Fuselage

Fuselage pronounced fyoo-suh-lahzh, fyoo-suh-lij, fyoo-zuh-lahzh or fyoo-suh-lahzh)

(1) In aeronautical design, the complete central structure of an airplane, to which are attached the wings (or rotors), tail and other stabilizing fins or surfaces (engines sometimes also directly attached or enclosed).  It is inside the fuselage where the crew, passengers, cargo and most internals systems are located.

(2) In design, a style which borrows from or alludes to the elements used in aircraft fuselages.

(3) By extension, the main body of an aerospace vehicle

1909 (In English): From the French fuselage, the construct being fusel(é) (spindle-shaped), from fuseler (to shape like a spindle), from the Old French fus or fuseau (spindle), from the Latin fusus (spindle) + -age.  The French suffix -age was from the Middle & Old French -age, from the Latin -āticum, (greatly) extended from words like rivage and voyage.  It was used usually to form nouns with the sense of (1) "action or result of Xing" or (more rarely), "action related to X" or (2) "state of being (a or an) X".  A less common use was the formation of collective nouns.  Historically, there were many applications (family relationships, locations et al) but use has long tended to be restricted to the sense of "action of Xing".  Many older terms now have little to no connection with their most common modern uses, something particularly notable of those descended from actual Latin words (fromage, voyage et al).  In English, the suffix -age was from the Middle English -age, from the Old French -age, from the Latin -āticum.  Cognates include the French -age, the Italian -aggio, the Portuguese -agem, the Spanish -aje & Romanian -aj.  It was used to form nouns (1) with the sense of collection or appurtenance, (2) indicating a process, action, or a result, (3) of a state or relationship, (4) indicating a place, (5) indicating a charge, toll, or fee, (6) indicating a rate & (7) of a unit of measure.  Fuselage is a noun & adjective; the noun plural is fuselages.

Many languages also borrowed fuselage but there were sometimes variations in spelling including in Catalan (fuselatge), Portuguese (fuselagem), Spanish (fuselaje), Russian (fjuzeljáž (фюзеля́ж)), Kazakh (füzeläj (фюзеляж)) and Ukrainian (fjuzeljáž (фюзеля́ж)).  It’s not clear when “fuselage” was first used in English, the earliest known reference dating from 1909 but it’s not improbable the word had earlier been in oral use.  The alternative was presumably “hull” (the body or frame of shop, boat or other such vessel).  Hull was from the Middle English hul, hulle & holle (seed covering, hull of a ship), from the Old English hulu (seed covering), from the Proto-Germanic hul- (and related to the Dutch hul (hood) and the German Hülle & Hülse (cover, veil)), and may have been from either the primitive Indo-European forms ḱel- (to cover, hide) or kal- (hard).  Hull came into wide use in aircraft design when “flying boats” were developed.

Flying boats: Short S.25 Sunderland (1938-1946) (left) and Dornier Do X (1929-1932) (right). 

Most aeroplanes have fuselages; flying boats have hulls, a tribute to the nautical part of their hybrid origin.  Commercially, flying boats were widely used during the inter-war years because of their range and, needing only a suitable body of water (sea, lake, river), their ability to operate in regions without suitable aerodromes.  A vital military machine during World War II (1939-1945), the advances in aircraft design during that conflict, coupled with the proliferation of airstrip construction able to be re-purposed for civil use doomed them for all but some specialist uses.  Quickly they almost vanished from European and (most) North American skies and waterways, enduring in the Far East only until infrastructure there too was improved.

The fuselage can be optional: Dunne D.5 (1908) (left), Northrop YB-49 prototype (1947) (centre) and Northrop Grumman B-2 Spirit (1989) (right).

In the early days of aviation, before even an airplane had flown the English Channel, designers had been intrigued when their slide-rule calculations suggested the optimal shape of a flying machine was a "flying wing" with no conventional fuselage and certainly no tail-plane apparatus.  Tests of scale models in primitive wind tunnels proved the math was substantially correct and proof of concept tests using an unpowered glider proved inconclusive, it being clear only a powered flight would demonstrate if such a design could achieve stable flight.  When tested, the designer admitted an early, under-powered, version was "more a hopper than a flyer" but when fitted with more powerful engines, the "flying wings" proved remarkably stable.  However, more conventional designs proved more suitable for military use and that, increasingly was where the source of funding was to be found.  Despite that, the idea continued to fascinate designers and a flying wing was one of the extraordinary range of experimental aircraft under development in Nazi Germany during World War II, most of which never made any contribution to the Luftwaffe's war effort.  In the US, Northrop built both propeller and jet-powered prototypes in the 1940s and after early difficulties, a stable platform emerged although, like most designs, it both offered advantages and imposed restrictions but the whole project was cancelled; ever since some have argued this was due to political influence while others claim the flaws in the concept were so fundamental they couldn't be fixed.  The Northrop Grumman B-2 Spirit (in service with the US Air Force (USAF) until at least 2034) is a modified version of a flying wing in that its really a variation of a delta with an integrated fuselage.

In the early days of aviation during the twentieth century’s first decade, French engineers and inventors were the most innovative on the planet and this is reflected in the world-wide adoption of many French terms for some of the bits and pieces which continue to be used.  English, rarely inclined to create a new word if there was a manageable one in some other language which could be absorbed (“borrowed” still the term etymologists, strangely perhaps, prefer) and the French words which formed the basis of the early lexicon of aviation are a particular example of technological determinism in language.  Other orthodox terms in aviation include:

Aileron: A hinged flight-control surface usually attached to the trailing edge of each wing and used to change the roll (ie cause fuselage to begin rotation).  Although the word “flaps” is commonly used of ailerons, the flaps are usually positioned closer to the fuselage and are used to increase or reduce lift & drag.  The flap-like devices mounted on the trailing edges of the vertical stabilizers (somewhere in the tail-section) are properly called “elevators”.  Aileron was a diminutive of aile (wing) and before powered flight (flying machines) had been used in ornithology to refer to the extremities of a bird's wings used to control their flight.  There is an entry in a French-English dictionary dating from 1877 (with the lead meaning: “small wing”) and in the context of the language of aviation, the earliest known use in entry in French technical literature is from 1908.

Empennage: The tail assembly of an aircraft, including the horizontal and vertical stabilizers, elevators, and rudder. Empennage was from the French empenner (to feather an arrow).

Chassis: This was the original term used in English to describe the framework of an aircraft but soon was replaced by "frame, structure etc"), presumably because of the association with the heavy steel constructions used in cars and trucks, things far removed from the lightweight designs needed in the air.  Chassis was from the French chassis (frame, supporting structure), from châsse (reliquary; coffin), from the Latin capsa (case).

Concours d'Elegance: Not strictly an aviation term and most associated with affairs like those in Pebble Beach where rows of vintage Bentleys, Ferraris and such (the latter always in a much better state of finish than when they left the factory) are judged for their closeness to perfection.  Although not strictly a term from aviation, there are such events for old aircraft.  Concours d'Elegance was from the French concours d'élégance (competition of elegance).

Pilot: Pilot was from the Middle French pilot & pillot, from the Italian pilota & piloto, (pedotta, pedot & pedotto the older forms), the pil- element probably influenced by pileggiare (to sail, navigate), ultimately from the unattested Byzantine Greek *πηδώτης (pēdṓtēs) (helmsman), from the Ancient Greek πηδόν (pēdón) (blade of an oar, oar) (the the Ancient and Modern Greek πηδάλιον (pēdálion) (rudder).  Familiar from nautical use, pilot was a straight borrowing for the person fulfilling the same function in the air.  The construct of pilotage was pilot + -age.

Canard: A type of aircraft configuration where the tail-plane is ahead of the main lifting surfaces.  In aviation, a canard is either (1) a type of aircraft in which the primary horizontal control and stabilization surfaces are in front of the main wing or (2) a horizontal control and stabilization surface located in front of the main wing of an aircraft (a fore-plane).  In just about any form of engineering involving movement and fluid dynamics (air, plasma, water etc), a canard is a small, wing-like structure used usually as a stabilizing device.  Canard was from the French canard (duck, hoax) and in English as “a canard”, is still used in that sense to mean “a false or misleading report or story, especially if deliberately so”.

The Fuselage Chryslers, 1968-1973

1969 Imperial LeBaron, four-door hardtop.

The “fuselage” Chryslers were released late in 1968 for the 1969 model year and, as a class, remain the largest regular production cars ever made by the US industry.  In the catalogue between 1968-1973, by the end of their run the Imperial was built on a 127 inch (3226 mm) wheelbase, was 235 ½ (5981 mm) inches in length and almost 80 (2022 mm) inches in width.  Big cars from Detroit were not uncommon in the 1960s (Buick in 1959 even naming their top-of-the-range model the Electra 225, a tribute to its 225 inch (5715 mm) length) but even by those standards the fuselage cars not only were vast but the bulbous shape (source of the “fuselage” tag) made them appear more excessive still; it wasn’t only for the big Chryslers the derisive “land yacht” was coined but the line exemplified the idea.  In fairness, the trend generally was “longer, heavier & fatter”, even once compact (by US standards) and agile machines like Ford’s Mustang and Thunderbird bloating with each update although the manufacturers were aware there was considerable public demand for something smaller and by the late 1960s, those in the pipelines were well-advanced.  However, demand for the full-sized cars remained strong and Chrysler decided their lines should be more full-sized than ever, thus the fuselage design.  There was at the time a bit of an aeronautical influence about and that was nothing new, jet aircraft and space rockets during the previous two decades having contributed many of the motifs which appeared on US cars.  During the development cycle for the fuselage cars, Chrysler were well-acquainted with the appearance of the Boeing 747, sketches circulating for some three years before its first public appearance in September 1968, coincidently just days after the Chrysler’s debuted.  In its appearance, the bulging 747 was the same sort of departure from the earlier, slender 707 as the 1969 Chryslers were from their rectilinear predecessors.

1969 Chrysler 300 advertising.  In graphics & text, the "fuselage" motif was integral to the promotion; it was no mere nickname. 

In some ways the styling has aged surprisingly well because the basic lines are uncluttered and, particularly on the higher priced editions, there was some nice detailing but at the time, critics found the look peculiar and a deviance from the direction other manufacturers were travelling.  The sides were unusually deep and rounded (recalling, obviously, an airplane’s fuselage) with a beltline so high the glasshouse (the cabin area defined by the windows) was relatively shallow, something accentuated by the surrounding bulk.  The corporation’s full-sized platform (internally the “C-Body”), it was shared by the Plymouth, Dodge, Chrysler and Imperial lines, the latter a surprise to some because since 1955 when it had been established as a separate division, the Imperial had been built on a unique platform.  However, despite some encouraging results in the 1950s, Imperial never achieved the volume which would have justified another unique platform so the line was merged into mainstream development.

1969 Imperial LeBaron advertising.  The "messaging" in this advertisement remains obscure.

The debut season saw good sales for the fuselage cars (though still more than 10% down on the previous C-Body (1965-1968)) but demand dropped precipitously in the next three years although sales were in buoyant in 1973 when many manufacturers set records; it was the last good year for the “old” American economy and the swansong of the long post-war boom built on cheap, limitless energy and the uniquely advantageous position the country enjoyed after the war; something squandered by the mistakes of more than one administration.  It was certainly unfortunate timing for Chrysler that the first oil crisis should hit just weeks after they had replaced the fuselage cars with something mechanically similar but with clever styling tricks (even the engineers admitted it was “nips & tucks; smoke & mirrors”), something dimensionally similar appeared both smaller and more modern.  Underneath, as the fuselage line had been, was essentially a good product, Chrysler’s basic engineering always good and while the big machines would never behave like a Lotus Elan, on the road they were competent and in most aspects as good as or better than the competition.

The last of Harry S Truman's (1884–1972; US president 1945-1953) many cars was a 1972 Chrysler Newport, the entry-level model in Chrysler's Fuselage range (some Plymouth & Dodge models were cheaper still).  Purchased some six months before his death, the licence plate (5745) was a special request, a reference to 7 May, 1945 (VE Day (Victory in Europe).  Truman was in office on that day and the plate has since permanently been retired.

The first oil shock hit demand for the 1974 cars and the timing was bad for all points in the production and distribution chain.  Noting the favourable reviews, dealers had ordered large stocks to meet the expected demand but the Arab Oil Embargo meant sales of big cars collapsed and the Chryslers, with V8 engines between 318-440 cubic inches (5.2-7.2 litres) were as thirsty as any of their ilk and supplies of cars expected to be sold in days languished on dealer’s lots for months.  In response, Chrysler shut down two manufacturing plants while trying to increase production or imports of small, fuel-efficient vehicles.  Sales of the big cars in 1974 were barely half those of the previous year and the breakdown of those was a harbinger for the whole industry, the numbers disproportionately slanted towards the higher-priced lines, the entry-level models attracting interest mostly from fleet operators and law enforcement.  The days of the low-cost big sedans which appealed to those like Harry Truman who liked the virtues without the ostentation, were over.

1978 Chrysler New Yorker advertising.  Still obviously bulky, the 1974-1978 re-style toned down the fuselage look although the interiors in tufted leather or velor became increasingly baroque.  Publications like Road & Track (R&T) where the writers disapproved of anything so big (they thought everyone should drive a Lancia) sneered at the extravagant fit-out, dismissing it as "gingerbread" but it was a luxurious and isolating environment.  There were still many who liked that sort of thing, none of whom maintained subscriptions to R&T.

So the writing was on the wall and even by 1977 when the oil crisis faded from memory and it seemed buyers were ready again to buy big, Chrysler was left with its now 1974 range while press and public fawned over General Motors’ (GM) newly slimmed-down, taut looking, full-size cars, the style and dimensions of which were so obviously the future.  Tellingly, while radically reduced in weight and external measurements, on the inside, they were in most places as capacious as both their predecessors and the now antique Chryslers which were still just an update of the 1969 fuselage range.  With the coming of 1976, the corporation had accepted the inevitable and axed the Imperial brand, Chrysler's top-of-the-range New Yorker tarted-up with left-over Imperial trim to become the new flagship.  The end was close and in 1978 it came, that the last year of the big Chryslers released with such high expectations a decade before and when the line was retired, it took with it the once popular four-door hardtop body-style, other manufacturers having already retired their models.  Shockingly inefficient though they are, the few surviving land yachts have a small but devoted following who appreciate what remains a unique driving experience (one as enjoyable as a passenger) and it's unlikely anything like them will ever be built again.

Prompt

Prompt (pronounced prompt)

(1) Something done, performed, delivered etc at once or without undue delay.

(2) Ready & quick to act as the circumstances demand (archaic).

(3) Quick or alert.

(4) Punctual.

(5) To move or induce to action; to occasion or incite (often as “prompted”).

(6) To assist by suggesting something.

(7) To remind someone of what has been forgotten (formalized in live performance (the stage, singing etc) where a “prompt” is a supplied from the wings to remind a performer of a missed cue or forgotten line (the noun prompter can indicate both a person employed to deliver cues or the device used (printed or on a screen).

(8) In computing, the message or symbol on the screen which indicates where an entry is require, the most basic of which is the “command prompt” of text-based operating systems which stood ready to receive a structured command.

(9) In computing, in artificial intelligence (AI), machine learning algorithms (MLI) and related systems, to request particular output by means of instructions, questions, examples, context, or other input.

(10) In commercial use, a time limit given for payment of an account for produce purchased, this limit varying with different goods (archaic).

(11) In futures trading, the “front” (closest or nearest).

(12) The act of prompting.

1350-1400: From the Middle English prompte (ready, eager (adjective) & prompten (verb), from the French prompt, all forms ultimately from the Latin prōmptus (evident; manifest, at hand, ready, quick, prepared), participle of prōmō (to take or bring out or forth, produce, bring to light) and the adjectival use of past participle of prōmere (to bring forth, deliver, set forth), the construct being from prō- (forth, forward; for; on behalf of, in the interest of, for the sake of; before, in front of; instead of; about; according to; as, like; as befitting), a combining form of the preposition prō, from the Proto-Italic pro-, from the primitive Indo-European pro-, o-grade of per-) + emere (to buy, obtain, take).  The synonyms can include urge, spur, remind, refresh, instigate, impel, punctual, quick, rapid, hasty & timely.  Modifiers are applied as requited including over-prompt, quasi-prompt & un-prompt.  Prompt is a noun, verb & adjective, promptness & prompter are nouns, prompter & promptest are adjectives, promptly is an adverb and prompting & prompted are verbs; the noun plural is prompts.

The noun (in the phrase “in prompte”) emerged in the early fifteenth century in the sense of “readiness" and was from the Latin verb prōmptus while the more familiar meaning “hint, information suggested, act of prompting” dates from the mid-1500s.  The formal use of prompt in the sense of the indicator on a screen ready to accept user input dates only from 1977 although the concept had been in use for decades.  The ideas of coaching (someone) or assisting them by providing a reminder of that which clearly had been forgotten (or imperfectly learned) was first used in the early fifteenth century, the best-known use in live theatre (to assist a speaker with lines) dating from the 1670s.  The adjectival use (ready, prepared (to do something), quick to act as occasion demands) was from the thirteenth century Old French prompt and directly from Latin prōmptus (brought forth), hence “visible, apparent, evident, at hand”, a use now obsolete.  The commercial sense of the noun prompt “a time limit given for payment for merchandise purchased" dates from the mid-eighteenth and while the concept remains, the word is no longer formally use although the phrase “prompt payment requested” often remains as a reminder.  It remains unclear whether the verb was derived from the adjective or vice-versa and another oddity is that the first recorded instance of “prompting”, the gerund (the verbal noun logically derived from prompt and meaning “incitement or impulse to action” is from 1402, a quarter of a century before the verb.

The formal use of prompt in the sense of the indicator on a screen ready to accept user input dates only from 1977 although the concept had been in use for decades and predates screens, prompts emerging as soon as user input switched from the flicking of switches to character-based entries via a keyboard or similar input device.  The first prompts were those which sat (undifferentiated) on a plotter or printer, awaiting user input.  Command prompts were familiar from the late 1970s and appeared in early versions of Apple and CP/M systems among others but it was the IBM PC which introduced them to what was then the (still small) mainstream.  When the IBM PC was released in 1981, the user interface was exclusively text-based and the PC-DOS (or MS-DOS) command prompt was (almost) the only way for users to interact with their hardware and software.  The quirky exception to that was that on genuine IBM machines, the BIOS (Basic Input/Output System) included a BASIC (the Beginners All-Purpose Symbolic Instruction Code programming language) interpreter so it was possible to do certain things with the hardware even if an operation system (OS) wasn’t present.  IBM’s lawyers guarded their BIOS with rare efficiency so the numerous PC clones almost all needed an OS to be useful.

While programmers, nerds, and other obsessive types understood the charm of the command prompt and took to it fondly, most users had no wish to memorize even part of the sometime arcane command set needed and modern capitalism soon responded, menu systems soon available which allowed users to interact with their machine while hiding the essential ugliness beneath.  In time, these were augmented by graphical environments (some of which frankly overwhelmed the OS) and ultimately, the most successful of these would evolve into OSs, some of which included the ability to run multiple command prompts which at first contained and later emulated PC-MS-DOS.  The most elaborate of these was IBM’s OS/2 2.0 (and its successors) which permitted on a single machine literally hundreds of simultaneous command prompt sessions in a mix of 8, 16 & 32-bit flavors, some of which could even been launched as a bootable virtual machine, started from a floppy-diskette image.  Technically, it was an impressive achievement but around the planet, there were only a relative handful of organizations which needed such capabilities (typically those with megalomaniacs seduced by the idea of replacing perhaps dozens of MS-DOS based PCs each housing an interface handler of some type with one machine).  That could be made to work but the aggregate need was so limited that the direction proved a cul-de-sac.

The command prompt (with long file names, left) and the PowerShell prompt (right).  Both use the classic $p$g configuration.

The prompt didn’t however go away and in one form or another most OSs include one, Microsoft’s PowerShell (introduced in 2006 on Windows and ported to cross-platform compatibility within .NET in 2016) in its default configuration almost identical to that of the IBM-PC-1, all those years ago.  PowerShell included an enhanced list of commands but the earlier prompts were also not static and many options became available to customize the look, the list changing from release to release but a typical version included:

$Q (equal sign).
$$ $ (dollar sign).
$T (Current time).
$D (Current date).
$P (Current drive and path).
$V (OS version number).
$N (Current drive).
$G> (greater than sign).
$L & (less than sign).
$B| (pipe).
$E (Escape code (ASCII code 27)).
$_ (Carriage return and line feed).

Few actually customized their line beyond $P$G (so they would know the active sub-directory and that became the default with which most versions of PC/MS-DOS shipped) but $t $d$_$p$g had its followers (its displayed the time and the date above the prompt when in DOS.  Those for who aesthetics mattered could even set text and background colors and there were some genuinely nostalgic types who liked to emulate the bright orange or acid green screens they remembered from the world of the mainframes.  Most pleasing though was probably bright blue on black.

Prompt was one of the finalists for the Oxford University Press (OUP) 2023 Word Of The Year (WotY) although it didn’t make the cut for the shortlist.  Prompt was there not because the selection committee noted either a new international interest in punctuality or Microsoft’s PowerShell convincing a new generation to start enjoying a CLI (command-line interpreter) but because of the social and technological phenononom that is generative AI (artificial intelligence), the best-known of which is ChatGPT.  Of course, even those who weren’t dedicated command-line jockeys have for decades been interacting with the prompts of search engines but the influence of generative AI has been extraordinary and nudging “prompt” to OUP’s WotY finals is just a footnote, the editors noting even the emergence of a new job description: prompt engineer although, given the implications of generative AI, it might be a short-lived profession.  OUP also explained the expansion of meaning was a development of a wider sense: “Something said or done to aid the memory; a reminder” and that the earlier sense “prepared, ready” was long extinct although many clearly think of ChatGPT in this way.

Prompt would have been a worthy WotY and it’ll be with us for the foreseeable future, not something guaranteed for the winner: “Rizz”.  In its explanatory note, OUP sid rizz was “a popular Gen Z internet slang term”, a shortened form of the word “charisma”, used to describe someone’s ability to attract another person through style or charm, able also to be used as a verb (such as to “rizz up”, meaning to attract or chat up another person.  Rizz has about it the whiff of something which may quickly become cheugy (something once cool which became uncool by becoming too widely used by those who will never be cool) and the imprimatur of OUP’s WotY might be a nail in its coffin.  Time will tell but additionally, rizz is probably better click-bait than prompt, something to which even OUP's editors probably aren’t immune.  The other six finalists were:

Situationship: This describes a relationship (which may be sexual or romantic or neither) not thought (by the participants) formal or established (ie outside what are regarded as society’s conventions).  So, the state of relationship it describes in hardly new but it’s a clever use of language (the construct a portmanteau of situation + (relation)ship and it seems to have existed since around 2008-2011 (the sources differ) but its only recently that the use on social media and various dating apps and television shows that it’s achieved critical mass.

The anyway statuesque Taylor Swift, adding to the effect in 6 inch (150 mm) heels.

Swiftie: A (devoted / enthusiastic / obsessive etc) fan of the singer Taylor Swift (b 1989).  It was once pop culture orthodoxy that the particular conjunction of technological, demographic, economic and social conditions which were unique to the Western world in the 1960s meant what was described as the “claustrophobic hothouse” which produced “Beatlemania” couldn’t again happen.  While various pop-culture figures developed fan-bases which picked up descriptors (such as the “Dead Heads” associated with the Grateful Dead), the particular fanaticism surrounding the Beatles has never quite been replicated.  The Swifties however are said in devotion to go close and their numbers probably greater, Taylor Swift’s appeal truly cross-cultural and international; probably only the Ayatollahs and such are unmoved.  Etymologically, “Swiftie” is a conventional affectionate diminutive and among Swifties there are factions including die-hard Swifties, hardcore Swifties and self-proclaimed Swifties.  Someone a little ashamed of their fondness would presumably be a “confessed Swiftie” but none appear to exist and her appeal seems to transcend the usual pop-music boundaries.  Her songs are said to be "infectiously catchy" (a pleonasm she'd probably not allow in her lyrics).

Beige flag: Beige flag has a range and can be a trait which while not something distasteful or shocking, is of a nature which makes one pause and perhaps reconsider one’s relationship with whoever exhibits it.  It can be something which does little more than indicate the person isn’t interesting and is thus a adaptation of “red flag” which is something to which the only rational reaction is an immediate sundering of a relationship.  So a red flag might be being a Scientologist, a Freemason or listening to country & western music whereas a beige flag might be driving a front wheel drive car; undesirable but perhaps not a deal-breaker.  It can also mean something which suggests someone is just not interesting though not actually evil.  Of late however, the meaning of beige flag has shifted, thus it’s making OUP’s list of finalists.  Now, it appears to be used to reference traits which can be thought “neutral” and it’s been further adapted to cover those situations or objects which cause one briefly to pause, before moving on and probably forgetting what they’ve just seen.  It just wasn’t interesting.

Lindsay Lohan, de-influencing.

De-influencing: De-influencing is one which will probably annoy the pedants.  In the social media era, the word influencer has come to mean “someone who seeks to influence the consumption, lifestyle, political behavior etc of their online audience by the creation of social media content, often as a part of a marketing campaign”.  A de-influencer is “someone who attempts to discourage consumption of particular products or consumption in general using the same platforms”.  So the de-influencers are the latest in the long tradition of anti-materialists who have existed at least since Antiquity, whole schools of philosophy sometimes constructed around their thoughts.  There’s said to be a discernible increase in their presence on the socials and many are linked also the various movements concerned with environmental concerns, notably climate change.  The pedants will object because the de-influencers are of course trying to exert influence but OUP are right to note the trend and the associated word.

Heat dome: A heat dome is a persistent high-pressure weather system over a particular geographic area, which traps a mass of hot air below it.  The weather phenomenon, the physics of which have for decades been understood by climate modelers and meteorologists, suddenly entered general in the high (northern) summer of 2023 when much of the northern hemisphere suffered from prolonged, unusually high temperatures, July measured as the hottest month ever recorded.  Under a heat dome, the atmospheric pressure aloft prevents the hot air from rising and dissipating, effectively acting as a lid or cap over the area, thus the image of a dome sitting over the land and they create their own feedback loop: Static areas of high pressure (which already contain warm or hot air trapped under the high) will become hotter and hotter, creating a heat dome.  Hot air will rise into the atmosphere, but high pressure acts as a lid and causes the air to subside or sink; as the air sinks, it warms by compression, and the heat builds. The ground also warms, losing moisture and making it easier to heat even more.  This is climate change in action and heat dome may well become as common an expression as “cyclone” or “hurricane”.

The UK's Royal Meteorological Service's simple illustration of the physics of a heat dome.  Heat domes are also their own feedback loop.  A static areas of high pressure which already contains warm or hot air trapped under the high will become hotter and hotter, creating a heat dome.  Hot air will rise into the atmosphere, but high pressure acts as a lid and causes the air to subside or sink; as the air sinks, it warms by compression, and the heat builds. The ground also warms, losing moisture and making it easier to heat even more.

Parasocial: The adjective parasocial designates a relationship characterized by the one-sided, unreciprocated sense of intimacy felt by a viewer, fan, or follower for a well-known or prominent figure (typically a pop-culture celebrity), in which the follower or fan comes to feel something similar to knowing the celebrity as they might an actual friend.  The parasocial is really a variation of fictosexual (an identity for someone for whom the primary form of sexual attraction is fictional characters) in that the pop-culture celebrity is also an at least partially fictional construct and the relationship is just as remote.  It’s almost irrelevant that one is flesh & blood and parasocial relationships do have certain advantages in that never having to have actual contact, one can never be rejected.  What appears most to have interested OUP is the idea that our relationship with celebrity culture is changing to something more intimate, presumably because the medium is the cell phone (mobile), increasingly our most personally intimate possession.

When one attempts transform a parasocial relationship into something conventional, one sometimes becomes a stalker.

(6) In the hierarchy of the Roman Catholic Church, a title used to address or refer to a cardinal (in the form “eminence”, “your eminence”, “his eminence” or “their eminences”).

(7) As “gray eminence” (the usual spelling of éminence grise), a “power behind the throne”.

1375–1425: From the late Middle English eminence (projection, protuberance (and by the early fifteenth century a “high or exalted position”)), from the Anglo-French, from the Old French eminence, from the Latin ēminēntia (prominence, protuberance; eminence, excellence; a standing out, a distinctive feature, most conspicuous part), the construct being equivalent to ēmin- (base of ēminēre (to stand out) + -entia (-ence) (the noun suffix), from eminentem (nominative eminens) (standing out, projecting (and figuratively “prominent, distinctive”)), from an assimilated form of the construct ex- (out) + -minere (related to mons (hill), from the primitive Indo-European root men- (to project).  The adjective eminent dates from the early fifteenth century and was used in the sense of “standing or rising above other places; exceeding other things in quality or degree” and was from the thirteenth century Old French éminent (prominent) or directly from the Latin eminentem.  From the 1610s, it came be used of those “distinguished in character or attainments”.  The noun pre-eminence (also as pre-eminence) was known as early as the twelfth century and then meant “surpassing eminence; superiority, distinction; precedence, a place of rank or distinction”.  It was from the Late Latin praeeminentia (distinction, superiority), from the Classical Latin praeeminentem (nominative praeeminens), the present participle of praeeminere (transcend, excel (literally “project forward, rise above”)) the construct being prae (before) + eminere (stand out, project).  The alternative for eminency is listed usually as archaic or obsolete.  Synonyms include conspicuousness, distinction, prominence, renown, celebrity, note & fame in the context of status and elevation or prominence when applied to topography.  Eminence & eminency are nouns, eminently is an adverb and eminent is an adjective (and a non-standard noun); the noun plural is eminences or eminencies.

The use in anatomy is to describe certain protuberances including (1) hypothenar eminence (plural hypothenar eminences) (the ulnar side of the human hand; the edge of the hand between the pinky and the outer side of the wrist, (2) ileocecal eminence (plural ileocecal eminences) (the ileocecal valve), (3) median eminence (plural median eminences) (part of the inferior boundary for the hypothalamus in the human brain and (4) frontal eminence (plural frontal eminences) (either of two rounded elevations on the frontal bone of the skull (known also as the “tuber frontale”).

Extract from xona.com's color list.

As a name for a deep or dark shade of purple, name eminence has been in regular use since the nineteenth century and there have always been variations in the shades so described; on the color charts of different manufacturers, this continues.  In digital use however, eminence as a shade of purple has been (more or less) standardized since 2001 when xona.com promulgated their influential color list.  Although “eminence” is the form of address for a cardinal in the Roman Catholic Church, it’s presumable this has no relationship with the color eminence because cardinals wear red and it’s the monsignors who don a purple which does look like the shade typically described as eminence.  As far as is known, the name “monsignor” has never been applied to any shade.  Monsignor is one of the honorary titles Popes for centuries granted to priests within their Papal Court and there were many degrees of these, conferred usually on priests worked closely with the Holy Father in Rome.  Over time, the use of monsignor was expanded and could be granted to priests beyond Rome on the recommendation of a bishop.  Recently, Pope Francis (b 1936; pope since 2013) has restricted this, returning to the older ways and this will have please some bishops, not all of whom were anxious to see too much purple in their diocese.  The monsignor’s purple (which most would probably call a magenta) was connected to the tradition in the Roman empire to vest new dignitaries with a purple toga and in medieval heraldry the color symbolized justice, regal majesty and sovereignty although not so much should be made of this in the context of the Vatican’s choices in ecclesiastical fashion: Originally, it was never envisaged monsignors would wander far from the Holy See.

Until the sixteenth century bishops wore green and this use persists on the traditional coat of arms that each bishop chooses when elected.  In the 1500s, the switch was made to “amaranth red,” named after the amaranth flower although, despite the name, the actual hue is more like fuchsia but, being similar to a purple, church historians maintain there’s some symbolic value linking with the bishop being charged to govern his local diocese.  Technically, the Holy See describes the color worn by cardinals as “scarlet” and their eminences are described as “princes” of the church although part of the mystique of the place is that the red symbolizes the blood they’re all supposed to be prepared to spill to defend the pope.  When the Pope places the biretta (the hat with 3 or 4 stiffened corners worn as part of liturgical dress) on top of the cardinal’s head, he says, “(This is) scarlet as a sign of the dignity of the cardinalate, signifying your readiness to act with courage, even to the shedding of your blood, for the increase of the Christian faith, for the peace and tranquility of the people of God and for the freedom and growth of Holy Roman Church.”  As a title of honor within the church, eminence was in use as early as the 1650s although apparently since the 1720s, the honorific has been exclusive to cardinals.

The term gray eminence was from the French éminence grise, plural eminences grises or eminence grises (literally “grey eminence” and the French spelling is sometimes used in the English-speaking world).  It was applied originally to François Leclerc du Tremblay (1577–1638), also known as Père Joseph, a French Capuchin friar who was the confidant and agent of Cardinal Richelieu (1585–1642), the chief minister of France under Louis XIII (1601–1643; King of France 1610-1643).  The term refers to du Tremblay’s influence over the Cardinal (who bore the honorific of Eminence), and the colour of his habit (he wore gray).  Aldous Huxley (1894–1963) sub-titled his biography of Leclerc (L'Éminence Grise (1941)): A Study in Religion and Politics.  Huxley discussed the nature of both religion & politics, his purpose being to explore the relationship between the two and his work was a kind of warning to those of faith who are led astray by proximity to power.

Use of the term éminence grise suggests a shadowy, backroom operator who avoids publicity, operating in secret if possible yet exercising great influence over decisions, even to the point of being “the power behind the throne”.  In this a gray eminence differs from a king-maker or a svengali is that those designations are applied typically to those who operate in the public view, even flaunting their power and authority.  Probably the closest synonym of the gray eminence is a “puppetmaster” because of the implication of remaining hidden, and although never seen, the strings they pull are if one looks closely enough.  The svengali was named for the hypnotist character Svengali in George du Maurier’s (1834–1896) novel Trilby (1894).  Svengali seduced, dominated and manipulated Trilby who was a young, half-Irish girl, transforming her into a great singer but in doing so he made her utterly dependent on him and this ruthlessly he exploited.

The brown eminence

Adolf Hitler (1889-1945; German head of government 1933-1945 & head of state 1934-1945) followed by his "brown eminence", Martin Bormann (1900–1945).

Bormann attached himself to the Nazi Party in the 1920s and proved diligent and industrious, rewarded in 1933 by being appointed chief of staff in the office of Rudolf Hess (1894–1987; Nazi Deputy Führer 1933-1941) where he first built his power base.  After Hess bizarrely flew to Scotland in 1941, Hitler abolished the post of Deputy Führer, assigning his offices to Bormann and styling him Head of the Parteikanzlei (Party Chancellery), a position of extraordinary influence, strengthened further when in 1943 he was appointed Personal Secretary to the Führer, a title he exploited to allow him to act as a kind of viceroy, exercising power in Hitler’s name.  Known within the party as the der brauner Schatten (the brown shadow) which was translated usually as “Brown Eminence” (an allusion to an éminence grise), he maintained his authority by controlling access to Hitler to whom his efficiency and dutifulness proved invaluable.  The "brown" refers to the Nazi's brown uniforms, a color adopted not by choice but because when the cash-strapped party in the 1920s needed uniforms for their Sturmabteilung (The SA, literally "Storm Division" or Storm Troopers and known as the "brownshirts"), what were available cheaply and in bulk was the stock of brown army clothing intended for use in the tropical territories the Germans would have occupied had they won World War I (1914-1918).  Bormann committed suicide while trying to make his escape from Berlin in 1945 although this wasn't confirmed until 1973.

Lindsay Lohan's inner eminence on film.

Lindsay Lohan (2011) by Richard Phillips & Taylor Steele.

Screened in conjunction with the 54^th international exhibition of the Venice Biennale (June 2011), Lindsay Lohan was a short film the director said represented a “new kind of portraiture.”  Filmed in Malibu, California, the piece was included in the Commercial Break series, presented by Venice’s Garage Center for Contemporary Culture and although the promotional notes indicated it would include footage of the ankle monitor she helped make famous, the device doesn't appear in the final cut.

At the festival, co-director Richard Phillips (b 1962) was interviewed by V Magazine and explained: “Lindsay has an incredible emotional and physical presence on screen.  “[She] holds an existential vulnerability, while harnessing the power of the transcendental — the moment in transition. She is able to connect with us past all of our memory and projection, expressing our own inner eminence.”

Pre 900: From the Middle English noun nail & nayl, from the Old English nægl and cognate with the Old Frisian neil, the Old Saxon & Old High German nagal, the Dutch nagel, the German Nagel, the Old Norse nagl (fingernail), all of which were from the unattested Germanic naglaz.  As a derivative, it was akin to the Lithuanian nãgas & nagà (hoof), the Old Prussian nage (foot), the Old Church Slavonic noga (leg, foot), (the Serbo-Croatian nòga, the Czech noha, the Polish noga and the Russian nogá, all of which were probably originally a jocular reference to the foot as “a hoof”), the Old Church Slavonic nogŭtĭ, the Tocharian A maku & Tocharian B mekwa (fingernail, claw), all from the unattested North European Indo-European ənogwh-.  It was further akin to the Old Irish ingen, the Welsh ewin and the Breton ivin, from the unattested Celtic gwhīnā, the Latin unguis (fingernail, claw), from the unattested Italo-Celtic əngwhi-;the Greek ónyx (stem onych-), the Sanskrit ághri- (foot), from the unattested ághli-; the Armenian ełungn from the unattested onogwh-;the Middle English verbs naile, nail & nayle, the Old English næglian and cognate with the Old Saxon neglian, the Old High German negilen, the Old Norse negla, from the unattested Germanic nagl-janan (the Gothic was ganagljan).  The ultimate source was the primitive Indo-European h₃nog- (nail) and the use to describe the metal fastener was from the Middle English naylen, from the Old English næġlan & nægl (fingernail (handnægl)) & negel (tapering metal pin), from the Proto-Germanic naglaz (source also of Old Norse nagl (fingernail) & nagli (metal nail).  Nail is a noun & verb, nailernailless & naillike are adjectives, renail is a verbs, nailing is a noun & vern and nailed is a verb & adjective; the noun plural is nails.

Nail is modified or used as a modifier in literally dozens of examples including finger-nail, toe-nail, nail-brush, nail-file, rusty-nail, garden-nail, nail-fungus, nail-gun & frost-nail.  In idiomatic use, a “nail in one's coffin” is a experience or event that tends to shorten life or hasten the end of something (applied retrospectively (ie post-mortem) it’s usually in the form “final nail in the coffin”.  To be “hard as nails” is either to be “in a robust physical state” or “lacking in human feelings or without sentiment”. To “nail one's colors to the mast” is to declare one’s position on something.  Something described as “better than a poke in the eye with a rusty nail” is a thing, which while not ideal, is not wholly undesirable or without charm.  In financial matters (of payments), to be “on the nail” is to “pay at once”, often in the form “pay on the nail”.  To “nail something down” is to finalize it. To have “nailed it” is “to perfectly have accomplished something” while “nailed her” indicates “having enjoyed sexual intercourse with her”.  The “right” in the phrase “hit the nail right on the head” is a more recent addition, all known instances of use prior to 1700 being “hit the nail on the head” and the elegant original is much preferred.  It’s used to mean “correctly identify something or exactly to arrive at the correct answer”.  Interestingly, the Oxford English Dictionary (OED) notes there is no documentary evidence that the phrase comes from “nail” in the sense of the ting hit by a hammer.

Double-headed nails are used for temporary structures like fencing.  When the shaft is hammered in to the point where the surface of the lower head is flat against the surface of that into which it's being hammered, it leaves the upper head standing proud with just enough of the shaft exposed to allow a claw-hammer to be used to extract nail.  There is a story that as part of an environmental protest against the building or demolition of some structure (the tales vary), activists early one morning went to the temporary fencing around the contested site and hammered in all the double-headed nails.  This is believed to be an urban myth.

The sense of “fingernail” appears to be the original which makes sense give there were fingernails before there were spikes (of metal or any other material) used to build stuff.  The verb nail was from the Old English næglian (to fix or fasten (something) onto (something else) with nails), from the Proto-Germanic ganaglijan (the source also of the Old Saxon neglian, the Old Norse negla, the Old High German negilen, the German nageln and the Gothic ganagljan (to nail), all developed from the root of the nouns.  The colloquial meaning “secure, succeed in catching or getting hold of (someone or something)” was in use by at least the 1760; hence (hence the law enforcement slang meaning “to effect an arrest”, noted since the 1930s.  The meaning “to succeed in hitting” dates from 1886 while the phrase “to nail down” (to fix in place with nails) was first recorded in the 1660s.

As a noun, “nail-biter” (worrisome or suspenseful event), perhaps surprisingly, seems not to have been in common use until 1999 an it’s applied to things from life-threatening situations to watching close sporting contests.  The idea of nail-biting as a sign of anxiety has been in various forms of literature since the 1570s, the noun nail-biting noted since 1805 and as a noun it was since the mid-nineteenth century applied to those individuals who “habitually or compulsively bit their fingernails” although this seems to have been purely literal rather than something figurative of a mental state.  Now, a “nail-biter” is one who is “habitually worried or apprehensive” and they’re often said to be “chewing the ends of their fingernails” and in political use, a “nail biter” is a criticism somewhat less cutting than “bed-wetter”.  The condition of compulsive nail-biting is the noun onychophagia, the construct being onycho- (a creation of the international scientific vocabulary), reflecting a New Latin combining form, from the Ancient Greek ὄνυξ (ónux) (claw, nail, hoof, talon) +‎ -phagia (eating, biting or swallowing), from the Ancient Greek -φαγία (-phagía).  A related form was -φαγος (-phagos) (eater), the suffix corresponding to φαγεῖν (phageîn) (to eat), the infinitive of ἔφαγον (éphagon) (I eat), which serves as aorist (essentially a compensator for sense-shifts) (for the defective verb ἐσθίω (esthíō) (I eat).  Bitter-tasting nail-polish is available for those who wish to cure themselves.  Nail-polish as a product dates from the 1880s and was originally literally a clear substance designed to give the finger or toe-nails a varnish like finish upon being buffed.  By 1884, it was being sold as “liquid nail varnish” including shads of black, pink and red although surviving depictions in art suggests men and women in various cultures have for thousands of years been coloring their nails.  Nail-files (small, flat, single-cut file for trimming the fingernails) seem first to have been sold in 1819 and nail-clippers (hand-tool used to trim the fingernails and toenails) in 1890.

The expression "nail down the lid" is a reference to the lid of a coffin (casket), the implication being one wants to make doubly certain anyone within can't possible "return from the dead".  The noun doornail (also door-nail) (large-headed nail used for studding batten doors for strength or ornament) emerged in the late fourteenth century and was often used of many large, thick nails with a large head, not necessarily those used only in doors.  The figurative expression “dead as a doornail” seems to be as old as the piece of hardware and use soon extended to “dumb as a doornail” and “deaf as a doornail).  The noun hangnail (also hang-nail) is a awful as it sounds and describes a “sore strip of partially detached flesh at the side of a nail of the finger or toe” and appears in seventeenth century texts although few etymologists appear to doubt it’s considerably older and probably a folk etymology and sense alteration of the Middle English agnail & angnail (corn on the foot), from the Old English agnail & angnail.  The origin is likely to have been literally the “painful spike” in the flesh when suffering the condition.  The first element was the Proto-Germanic ang- (compressed, hard, painful), from the primitive Indo-European root angh- (tight, painfully constricted, painful); the second the Old English nægl (spike), one of the influences on “nail”.  The noun hobnail was a “short, thick nail with a large head” which dates from the 1590s, the first element probably identical with hob (rounded peg or pin used as a mark or target in games (noted since the 1580s)) of unknown origin.  Because hobnails were hammered into the leather soles of heavy boots and shoes, “hobnail” came in the seventeenth century to be used of “a rustic person” though it was though less offensive than forms like “yokel”.

In the 1930s, the straight-8 became a favorite for manufacturers of luxury cars, attracted by its ease of manufacture (components and assembly-line tooling able to be shared with straight-sixes), the mechanical smoothness inherent in the layout and the ease of maintenance afforded by the long, narrow configuration.  However, the limitations were the relatively slow engine speeds imposed by the need to restrict the “crankshaft flex” and the height of the units, a product of the long strokes used to gain the required displacement.  By the 1950s, it was clear the future lay in big-bore, overhead valve V8s although the Mercedes-Benz engineers, unable to forget the glory days of the 1930s when the straight-eight W125s built for the Grand Prix circuits generated power and speed Formula One wouldn’t again see until the late 1970s, noted the relatively small 2.5 litre (153 cubic inch) displacement limit for 1954 and conjured up a quixotic final fling for the layout.  Used in both Formula One as the W196R and in sports car race as the W196S (better rememberd as the 300 SLR) the new 2.5 & 3.0 litre (183 cubic inch) straight-8s, unlike their pre-war predecessors, solved the issue of crankshaft flex by locating the power take-off at the centre, adding mechanical fuel-injection and a desmodromic valve train to make the things an exotic cocktail of ancient & modern.  Dominant during 1954-1955 in both Formula One & the Sports Car Championship, they were the last of the straight-8s.

Schematic of Buick “Nailhead” V8, 1953-1966.

Across the Atlantic, the US manufacturers also abandoned their straight-8s.  Buick introduced their overhead valve (OHV) V8 in 1953 but, being much wider than before, the new engine has to be slimmed somewhere to fit between the fenders; it would not be until later the platform was widened.  To achieve this, the engineers narrowed the cylinder heads, compelling both an conical (the so-called “pent-roof”) combustion chamber and an arrangement in which the sixteen valves pointed directly upwards on the intake side, something which not only demanded an unusual pushrod & rocker mechanism but also limited the size of the valves.  So, the valves had to be tall and narrow and, with some resemblance to nails, they picked up the nickname “nail valves”, morphing eventually to “nailhead” as a description of the whole engine.  The valve placement and angle certainly benefited the intake side but the geometry compromised the flow of exhaust gases which were compelled through their anyway small ports to make a turn of almost 180^o on their way to the tailpipe.

It wasn't the last time the head design of a Detroit V8 would be dictated by considerations of width.  When Chrysler in 1964 introduced the 273 cubic inch (4.5 litre) V8 as the first of its LA-Series (that would begat the later 318, 340 & 360 as well as the V10 made famous in the Dodge Viper), the most obvious visual difference from the earlier A-Series V8s was the noticeably smaller cylinder heads.  The A engines used as skew-type valve arrangement in which the exhaust valve was parallel to the bore with the intake valve tipped toward the intake manifold (the classic polyspherical chamber).  For the LA, Chrysler rendered all the valves tipped to the intake manifold and in-line (as viewed from the front), the industry’s standard approach to a wedge combustion chamber.  The reason for the change was that the decision had been taken to offer the compact Valiant with a V8 but it was a car which had been designed to accommodate only a straight-six and the wide-shouldered polyspheric head A-Series V8s simply wouldn’t fit.  So, essentially, wedge-heads were bolted atop the old A-Series block but the “L” in LA stood for light and the engineers wanted something genuinely lighter for the compact (in contemporary US terms) Valiant.  Accordingly, in addition to the reduced size of the heads and intake manifold, a new casting process was developed for the block (the biggest, heaviest part of an engine) which made possible thinner walls.

The nailhead wasn’t ideal for producing ultimate power but it did lend itself to prodigious low-end torque, something much appreciated by Buicks previous generation of buyers who has enjoyed the low-speed responsiveness of the famously smooth straight-8.  However, like everybody else, Buick hadn’t anticipated that as the 1950s unfolded, the industry would engage in a “power race”, something to which the free-breathing Cadillac and Chrysler’s Hemis were well-suited.  The somewhat strangulated Buick Nailhead was not at all suited and to gain power the engineers were compelled to add high-lift, long-duration camshafts which enabled the then magic 300 horsepower number to be achieved but at the expense of smoothness and tales of Buick buyers returning to the dealer to fix the “rumpity-rump” idle became legion.  Still, the Nailhead was robust, relatively light and offered what was then a generous displacement and the ever inventive hot-rod community soon worked out the path to power was to use forced induction and reverse the valve use, the supercharger blowing the fuel-air mix through the exhaust ports and the exhaust gases through the larger intake ports.  Thus the for a while Nailhead enjoyed a career as a niche player although the arrival in the mid 1950s of the much more tunable Chevrolet V8s ended the vogue for all but a few devotees who continued use well into the 1960s.  Buick acknowledged reality and, unusually, instead of following the industry trend and drawing attention to cubic inch displacement and horsepower, publicized their torque output, confusing some (though probably not Buick buyers who were a loyal crew).

Lockheed SR-71 Blackbird (1964-1999).

Not confused was the United States Air Force (USAF) which was much interested in power for its aircraft but also had a special need for torque on the tarmac and that briefly meant another small niche for the Nailhead.  The Lockheed SR-71 Blackbird (1964-1979) was a long-range, high-altitude supersonic (Mach 3+) aircraft used by the (USAF) for reconnaissance between 1966-1998 and by the National Aeronautics & Space Administration (NASA) for observation missions as late as 1999.  Something of a high-water mark among the extraordinary advances made in aeronautics and materials construction during the 1950s & 1960s, the SR-71 used the Pratt & Whitney J58 turbojet engine which used an innovative, secondary air-injection system to the afterburner, permitting additional thrust at high speed.  The SR-71 still holds a number of altitude and speed records and Lockheed’s SR-72, a hypersonic unmanned aerial vehicle (UAV) is said to be in an “advanced stage” of design and construction although whether any test flights will be conducted before 2030 remains unclear, the challenges of sustaining in the atmosphere velocities as high as Mach 6+ onerous given the heat generated.

At the time, the SR-71 was the most exotic aircraft on the planet but during testing and early in its career, to fly, it relied on a pair of even then technologically bankrupt Buick Nailhead V8s.  These were mounted in a towed cart and were effectively the turbojet’s starter motor, a concept developed in the 1930s as a work-around for the technology gap which emerged as aero-engines became too big to start by hand but no on-board electrical systems were available to trigger ignition.  The two Nailheads were connected by gears to a single, vertical drive shaft which ran the jet up to the critical speed at which ignition became self-sustaining.  The engineers chose the Nailheads after comparing them to other large displacement V8s, the aspect of the Buicks which most appealed being the torque generated at relatively low engine speeds, a characteristic ideal for driving an output shaft.  After the Nailhead was retired in 1966, later carts used Chevrolet big-block V8s but in 1969 a pneumatic start system was added to the infrastructure of the USAF bases from which the SR-71s most frequently operated, the sixteen-cylinder carts relegated to secondary bases the planes rarely used.
