1350–1400: From the Middle English loupe & loup (loop of cloth; loophole; noose), from the earlier lowp-knot (loop-knot), of North Germanic origin, from the Old Norse hlaup (a run), used in the sense of “a running knot”, from hlaupa (to leap), ultimately from the Proto-Germanic hlaupaną (to leap, run) (and related to the Swedish löp-knut (loop-knot), the Danish løb-knude (a running knot) and the Danish løb (a course)..Etymologists are divided over whether loop has any connection with the Middle Irish & Old Irish lúb (bend, fold, loop) and perhaps akin to “leap”; nor is it clear if there was any relationship with the Middle Dutch lūpen (lie in wait, peep, peer).  The special use in metalworking dates from 1665-1675 and was etymologically unrelated; it was from the French loupe, a special use of loupe (wen, knob, gnarl), ultimately from a Germanic source.  The verb was derived from the noun.  Loop & looping are nouns & verbs, looper is a noun, looped is a verb & adjective and loopable & loopy are adjectives; the noun plural is loops.

Inner hippie: Lindsay Lohan likes the peace sign and made it her signature gesture but in an age when high definition photography makes possible, even at a distance, the precise capturing of the arches, loops, and whorls of fingerprints, it’s now a potential risk.  AI (artificial intelligence) engines are now reported as achieving a success rate in excess of 50% in generating fake fingerprints so accurately they can “fool” biometric scanners.

As an acronym, LOOP can mean (1) loss of offsite power, (2) Listed on Other Page (online marketplaces), (3) Law of One Price (finance; economic theory) and Long-Range Open Ocean Patrol (admiralty jargon).  In dactylography (the study of fingerprints), the three primary shapes assumed by the ridges (arches, loops, and whorls) were first formerly defined in 1880.  It was first used of magnetic recording tape or film in 1931 while in computer programming in the sense of “a sequence of instructions, executed repeatedly”, the first known reference dates from 1947.  The noun looper (plural loopers) can mean (1) someone who loops (in various contexts, (2) an instrument or tool, such as a bodkin, for forming a loop in yarn or cord etc, (3) A moth having a caterpillar which arches its body into a loop in order to bring the back part of the body forward as it walks due to having fewer prolegs (an appendage of the abdomen of some insect larvae), (4) a (no almost always electronic) tool for creating music loops, (5) a golf caddy and (6) in baseball, a synonym of blooper (a fly ball that is weakly hit just over the infielders).  The adjective loopy can describe (1) something in such a shape or (2) (in slang) someone thought crazy or deranged.  The latter meaning dates from as late as 1923 but a century earlier it had entered English in the sense of “crafty or deceitful) in the novels of Sir Walter Scott (1771–1832).

There are literally dozens of derived “loop” phrases and idiomatic forms, some of the better known being: “infinite loop” (also as endless loop) (in computer programming a series of instructions which repeats until interrupted), “feedback loop” (a self-reinforcing or self-weakening effect which was used in the language of the military, political science, psychology, physics and other fields before becoming popular in discussions of global warming, “close the loop” (in managerial jargon, to follow up; to tie up loose ends; to resolve), “in the loop” (being well-informed; up to date; having current knowledge; being part of the discussion; the companion antonym being “out of the loop”, “fruitloop” (someone thought crazy or deranged (Fruit Loops originally a brand of sugary breakfast cereal), “death loop” (in video gaming the situation in which a player is killed and then respawns in the exact same time and place, destined thus endlessly to be killed, usually in a gruesome way, “belt loop” (the fittings on trousers & skirts through which one’s belt passes), “Lebanese loop” (in slang the “skimming device” fitted to an automatic teller machine (ATM or “cash dispenser”) used by criminals to collect personal information (such as pin numbers), “loophole” (in figurative use an ambiguity or exception in a rule or law that can be exploited in order to avoid the usual consequences (and originally "a slit in a castle wall used for observation or mounting a weapon)) and “loop quantum gravity” (a mysterious theory which attempts to reconcile quantum mechanics and general relativity, according to which space can be regarded as an extremely fine fabric of finite loops).

In the loop: MECCA MAXIMA, Bondi Junction, Sydney, Australia.

MECCA Cosmetica is an Australian cosmetics house with a presence in Australia, New Zealand, the UK and the PRC (People’s Republic of China), its private label brands including Mecca Cosmetica, Mecca Max, Kit and Mecca-ssentials.  It runs a programme (a kind of hybrid of a loyalty & reward scheme) called “Beauty Loop”, organized into layers, the parameters of which are based on one’s annual spend; as one spends more, one ascends to a higher level and, the higher one’s level, the greater the rewards (ie an effective discount).  The MECCA Beauty Loop has four levels of recognition (1, 2, 3 & 4) and purchases made online or in-store contribute to one’s annual total.  MECCA labels the customer profile in the Beauty Loop layers progressively as (1) Beauty Discoverer, (2) Beauty Devotee (3) Beauty Aficionado and (4) Beauty Connoisseur, explaining the Beauty Loop mechanics thus:

All this and more when you spend $3,500 AUD per year (12 months).

Although the Murdoch press in April 2025 published a long critique of the scheme (their "inside information" obtained on this occasion without having to resort to phone hacking), Beauty Loop remains popular, said now to enjoy a membership in excess of 4½ million Beauty Discoverers, Devotees, Aficionados & Connoisseurs (MECCA doesn’t publish a breakdown) but in 2023 there emerged on-line speculation there may be an exclusive, secret layer of the loop (presumably known as Level 5) for those who spend much more.  It all sounded quite Masonic and there was speculation at least some MECCA staff must know about the mysterious Level 5 but were not permitted to discuss it and, if asked, were instructed to deny the existence of such a thing.  What Level 5 Beauty Loop members would be called attracted speculation and the most popular suggestions were “Beauty Addict”, “Beauty Obsessive” & “Beauty Cultist”, the consensus being floor staff would be able to confirm the identity of Level 5 members by some unobvious and ambiguous flag in the MECCA database rather than something Masonic like a secret handshake.

Fueling the conspiratorial atmospherics, MECCA adopted the Pentagon's "neither confirm nor deny" policy (invoked usually when questioned about the existence of nuclear weapons in certain places) so the hunt for a MECCA "deep throat" began and in mid 2024 it was revealed one had been found (apparently called “Jillie” according to the Alex Hourigan and Sally McMullen, hosts of the podcast Two Broke Chicks)  What “Jillie” disclosed was the mystical “Level 5” really existed and it was an “exclusive, invitation-only” stratum atop the loop and it was called the “Magic Circle”.  While the exact metrics have never been confirmed by a reliable source, the implication was Magic Circle members received tailored gifts, exclusive access to events, and a deeper level of personalization from MECCA.  Quite how high one’s annual Mecca-spend need to be to enter (and presumably retain) one’s place in the Magic Circle isn’t known but the consensus among the MECCA congregation is it will be in excess of Aus$10,000.  The secret out, a MECCA representative did respond to media requests and issued a statement: “Through Magic Circle we provide personalised service and access to exclusive events and opportunities to a select group of our most passionate and loyal Level 4 customers.  Our Magic Circle customers are those who regularly shop with Mecca, engage with our team and are active members of our beauty-loving community.”  Now we know.

KGB identity card, issued in 1982 for British SIS defector Kim Philby (1912–1988).

In his sometimes reliable memoirs, the English Soviet spy Kim Philby (1912–1988 and one of the “Cambridge Five”) wrote “One does not look twice at an offer of enrolment in an elite force”, a comment which reveals a state of mind probably still prevalent among a certain class in the UK: that somewhere, close but not quite within reach, there exists an exclusive group in which resides the “real” power and influence.  Paradoxically, it was among those conventionally though part of “the establishment” that the longing to be part of this “inner ring” was strongest.  The English writer, literary scholar and Anglican lay theologian C. S. Lewis (1898–1963) in an essay published in 1944 noted the phenomenon and claimed: “Of all the passions, the passion for the inner ring is most skilful in making a man who is not yet a bad man do very bad things.  Philby of course came to do very bad things  Whether MECCA cultists would, in their quest to be part of the Magic Circle, be prepared to resort to what the KGB’s double agents did can’t be predicted but Kim Philby certainly would have understood their obsession.

Curiously (and presumably coincidentally), the term “magic circle” was used of the mechanism by which a leader of the UK’s Conservative and Unionist (Tory) Party “emerged”, the system still in place as recently as 1963.  Tory Party leaders have been elected by a formal vote only since 1965 and even then, until 2001, it was only MPs who voted.  Prior to that, a leader was said to “emerge” from what was known as a “magic circle” and although never as mysterious as some suggested, it was an opaque process, conducted by party grandees.  The classic example was in 1957 when the choice was between Harold MacMillan (1894-1986; UK prime-minister 1957-1963) and Rab Butler (1902-1982).  To his office in the House of Lords, the lisping (fifth) Lord Salisbury (1983-1972) summoned those he thought good chaps (women at this point hadn’t yet become chaps) and asked “Hawold or Wab?  Hawold prevailed.

The change in process in 1965 came about at the insistence of Sir Alec Douglas-Home (1903-1995 and the fourteenth Earl of Home before in 1963 disclaiming his peerage to become prime-minister (1963-1964)).  Since 1957, the country had changed and there was much criticism of the murky manner by which Sir Alec had become party leader with a clamour, even within the party, both to modernize and appear more transparently democratic.  From this point, unleashed were the forces which would in 1975 see Margaret Thatcher (1925-2013; UK prime-minister 1979-1990) elected leader but the first beneficiary of the wind of change was Edward "Ted" Heath (1916-2005; UK prime-minister 1970-1974), a grammar school boy who replaced the quondam fourteenth earl.  Notably, to appear more modern, Heath in 1965 didn't repair (as he had with MacMillan when he emerged in 1957), to the Turf Club for a celebratory meal of oysters, game pie and champagne which “…might have made people think a reactionary regime had been installed”.  

A beltless Lindsay Lohan’s daring display of naked belt loops; note the fetching hooking of the thumbs (right).  A belt will usually include a loop next to the buckle, used to keep the end of the belt in place.  This is called the "keeper".

It can be hard now to understand quite what a change Heath's accession in 1965 flagged; the Tory Party previously had leaders from the middle class but never the lower middle class.  The significance of what emerged in 1965 was less the new leader than a changed Tory Party in a changed country.  Whether a more democratic process than the magic circle means much of a change in the character of the figure chosen seems doubtful because whatever happens, the extent of the variation probably is still something like that once described by Georges Clemenceau (1841–1929; Prime Minister of France 1906-1909 & 1917-1920) as the difference between: "a politician who would murder their own mother and one prepared to murder only someone else's mother".  Nor has the change in process likely to have discouraged those anxious to make it to the top of the “greasy pole”.  When the office beckoned Lord Melbourne (1779-1848; UK prime-minister 1834 & 1835-1841), he was disinclined to accept, fearing it would be “…a damned bore” but his secretary persuaded him, saying “…no Greek or Roman ever held the office and if it lasts but three months it’ll still be worthwhile to have been Prime Minister of England”.  That thought remains to console Liz Truss (b 1975; UK prime-minister Sep-Oct 2022) who, despite it all, can still remember and be glad.

Snarge

Snarge (pronounced snn-arj)

(1) In military & civil aviation, slang, the remains of a bird after it has collided with an airplane (ie bird strike), originally of impacts with turbine engines but latterly applied also to residue left on wings, fuselages etc.

(2) By adoption, the remains of birds and insects left on the windscreens of trains, cars, motorcycle fairings etc,

Early 2000s (probably): A portmanteau word, a blend of sn(ot) + (g)ar(ba)ge.  Snot (used here in the usual sense of “mucus, especially that from the nose”) was from the Middle English snot & snotte, from the Old English ġesnot & snott, from the Proto-West Germanic snott & snutt, from the Proto-Germanic snuttuz (nasal mucus), from the same base as snout and related to snite.  It was cognate with the North Frisian snot (snot), the Saterland Frisian Snotte (snot), the West Frisian snotte (snot), the Dutch snot (snot), the German Low German Snött (snot), the dialectal German Schnutz (snot), the Danish snot (snot) and the Norwegian snott (snot).  Trans-linguistically, “snot” is commendably consistent and its other uses (a misbehaving (often as “snotty”) child; a disreputable man; the flamed-out wick of a candle all reference something unwanted or undesirable).  That said, snot (mucus) is essential for human life, being a natural, protective, and lubricating substance produced by mucous membranes throughout the body to keep tissues moist and act as a barrier against pathogens and irritants like dust and allergens, working to trap foreign particles; it also contains antimicrobial agents to fight infection.  So, when “out-of-sight & out-of-mind” it’s helpful mucus but when oozing (or worse) from the nostrils, it’s disgusting snot.

Garbage (waste material) was from the late Middle English garbage (the offal of a fowl, giblets, kitchen waste (though in earlier use “refuse, that which is purged away”), from the Anglo-Norman, from the Old French garber (to refine, make neat or clean), of Germanic origin, from the Frankish garwijan (to make ready).  It was akin to the Old High German garawan (to prepare, make ready) and the Old English ġearwian (to make ready, adorn).  The alternative spelling was garbidge (obsolete or eye dialect).  Garbage can be used of physical waste or figuratively (ideas, concepts texts, music etc) judged to be of poor quality and became popular in computing, used variously to mean (1) output judged nonsensical (for whatever reason), (2) corrupted data, (3) memory which although allocated was no longer in use and awaiting de-allocation) or (4) valid data misinterpreted as another kind of data.  Synonyms include junk, refuse, rubbish, trash & waste.  Charlie Chaplin (1889–1977) used “Herr Garbage” as the name of the character who in The Great Dictator (1940) represented Dr Joseph Goebbels (1897-1975; Nazi propaganda minister 1933-1945).  Snarge is a noun and no derived forms have ever been listed but a creature which has become snarge would have been snarged and the process (ie point of impact) would have been the act of snarging.  Snarge is inherent the result of a fatality so an adjective like snargish is presumably superfluous but traces of an impact which may not have been fatal presumably could be described as snargelike or snargesque.

Dr Carla Dove at work in the Smithsonian's Feather Identification Laboratory, Washington DC.

The patronymic Dr Carla Dove (b 1962) is manager of the Feather Identification Laboratory at the Smithsonian Institution’s National Museum of Natural History in Washington DC where she heads a team identifying the types or species of birds that collide with military and civil aircraft.  She calls snarge “a term of art” (clearly she’s of the “eye of the beholder” school) and notes that although the scientific discipline of using snarge to determine the species involved in bird strikes began at the Smithsonian in 1960, the term doesn’t seem to have been coined there and its origin, like much slang with a military connection, is murky.  Although a 2003 article in Flying Safety magazine is sometimes cited as the source of the claim the word was “invented at the Feather Identification Laboratory”, Dr Dove is emphatic the staff there “borrowed it” from preparators (the technicians who prepare bird specimens for display or other uses by museums).  It certainly seems to have been in general use (in its specialized niche in military & aviation and wildlife safety circles) by at least the early-to-mid 2000s and the zeitgeisters at Wired magazine were in 2005 printing it without elaboration, suggesting at least in their editorial team it was already establish slang.  So, it may long have been colloquial jargon in museums or among those working in military or civil aviation long before it appeared in print but there no documentary evidence seems to exist.

The origin of the scientific discipline is however uncontested and the world’s first forensic ornithologist was the Smithsonian’s Roxie Laybourne (1910–2003).  In October, 1960, a Lockheed L-188 Electra flying as Eastern Airlines Flight 375 out of Boston Logan Airport had cleared the runway by only a few hundred feet when it flew into a flock of birds, the most unfortunate of which damaged all four engines, resulting in a catastrophic loss of power, causing the craft to nosedive into Boston Harbor, killing 62 of the 72 aboard.  Although the engines were turbo-props rather than jets, they too are highly susceptible to bird-strike damage.  At the time, this was the greatest loss of life attributed to a bird-strike and the FAA (Federal Aviation Authority) ordered all avian remains be sent to the Smithsonian Institution for examination.  There, Ms Laybourne received  the box of mangled bone, blood & feathers and began her investigation, her career taking a trajectory which would include not only the development of protocols designed to reduce the likelihood of bird strikes damaging airliners but also involvement with the USAF (US Air Force) & NASA (National Aeronautics and Space Administration).  Additionally, her work with the FBI (Federal Bureau of Investigation) and various police forces proved forensic ornithology could be of use a diagnostic tool in crime-solving; her evidence helping to convict murderers, kidnappers and poachers.  In 2025, journalist Chris Sweeney published The Feather Detective: Mystery, Mayhem, and the Magnificent Life of Roxie Laybourne, a vivid telling of the tale of a woman succeeding in a world where feminism had not yet wrought its changes.

Snarge on the nosecone of a Cessna Citation, Eisenhower Airport, Wichita, Kansas, July 2021.  The dent indicates the point of impact, the airflow holding the corpse in place.  By the time of landing, the leaked body fluids had congealed to act as a kind of glue.

The study of aviation bird strikes is obviously a specialized field but snarge has come also to be used in the matter of insect deaths, specifically what has come to be called the “windscreen phenomenon” (also as “windshield phenomenon” depending on linguistic tradition).  What that refers to is the increasingly common instances of people reporting they are seeing far fewer dead insects on the windscreens of their cars, many dating the onset of the decline to the late 1990s and the most common explanations offered for this are (1) climate change, (2) habitat loss and (3) the increasing use (or potency) of pesticides.  Individual observations of one’s windscreen now tending to accumulate less snarge than in years gone by is of course impressionistic and caution must be taken not to extrapolate the existence of a global trend from one piece of glass in one tiny part of the planet: what needs to be avoided is a gaboso (the acronym for Generalized Association Based On Single-Observation (also as the derived noun & verb) which is the act of taking one identifiable feature of someone or something and using it as the definitional reference for a group (it ties in with logical fallacies).  However, the reports of increasingly snargeless windscreens were widespread and numerous so while that didn’t explain why it was happening, it did suggest that happening it was.

There was also the matter of social media platforms which have meant the volume of messages about a particular topic in the twenty-first century is not comparable with years gone by.  It’s simply impossible to calculate the extent to which these mass-market (free) platforms have operated as an accelerant (ie a force-multiplier of messaging) but few doubt it’s a considerable effect.  Still, it is striking the same observations were being made in the northern & southern hemispheres and the reference to the decline beginning in the late 1990s was also consistent and a number of studies in Europe and the US have found a precipitous drop in insect populations over the last three decades.  One interesting “quasi theory” was the improved aerodynamic efficiency of the modern automobile meant the entomological slaughter was reduced but quickly aeronautical engineers debunked that, pointing out a slippery shape has a “buffer zone” very close to the surface which means "bugs" have a greater chance of being sucked-in towards the speeding surface because of the differential between negative & positive pressure.  However, on most older vehicles, the “buffer zone” could be as much as 3 feet (close to a metre) from the body.  A bug heading straight for the glass would still be doomed but the disturbed air all around would have deflected a few

Lindsay Lohan with Herbie in Herbie: Fully Loaded (2005).

Herbie was a 1963 Volkswagen Type 1 (Beetle, 1938-2003) and despite the curves which made it look streamlined, its measured Cd (drag coefficient) was typically around 0.48-0.50, some 8% worse than contemporary vehicles of comparable frontal area.  What that meant was its buffer zone would extend somewhat further than the “New Beetle” (1997-2011) which had a Cd between 0.38-0.41, again not as good as the competition because it was compromised by the need to maintain a visual link with the way things were done in 1938.  On the 1963 models (like Herbie) the flat, upright windscreen created significant drag and was obviously a good device for “snarge harvesting” but the later curved screen (introduced in 1973 with the 1303) probably didn’t spare many insects.

Dr Manu Saunders' graphic example of insect snarge on a windscreen during the 2010 "locust plague" in western NSW (New South Wales), Australia, April 2010.

Dr Manu Saunders is a Senior Lecturer in Ecology and Biology and the School of Environmental and Rural Science in Australia’s UNE (University of New England) and she pointed out that “anecdata is not scientific evidence” and just because anecdotes are commonly presented as “evidence of global insect decline” (the so-called “insectageddon”), that doesn’t of necessity make locally described conditions globally relevant.  The problem she identified was that although there have been well-conducted longitudinal studies of snarge on windscreens using sound statistical methods, all have used data taken from a relatively small geographical area while around the planet, there are more than 21 million km (13 million miles, (ie more than 80 round trips to the Moon) of “roads”).  Dr Saunders does not deny the aggregate number of insects is in decline but cautions against the use of one data set being used to assess the extent of a phenomenon with a number of causal factors.

Still snarge-free: The famous photograph of the 25 917s assembled for inspection outside the Porsche factory, Stuttgart, 1969.  The FIA’s homologation inspectors declined the offer to test-drive the 25 which was just as well because, hastily assembled (secretaries, accountants and such drafted in to help), some of were capable of driving only a short distance in first gear.

Fortunately for Porsche, in 1969, although the decline in global insect numbers may already have begun, they were still buzzing around in sufficient numbers to produce the snarge which provided the necessary clue required to resolve the problem of chronic (and potentially lethal) instability which was afflicting the first 917s to be tested at speed.  In great haste, the 917 had been developed after the Fédération Internationale de l'Automobile (the FIA; the International Automobile Federation and world sport's dopiest regulatory body) “relaxed” the rules which previously had set a threshold of 50 identical units for cars classified as Group 4 (5 litre (305 cubic inch)) sports cars, reducing this to a minimum of 25.  What that meant was Porsche needed to develop both a car and a twelve cylinder engine, both items bigger and more complex than anything they’d before attempted, things perhaps not overly challenging had the typical two years been available but the factory needed something which would be ready for final testing in less than half the time.  Remarkably, they accomplished the task in ten months.

Porsche 917 LH Chassis 001 in the livery of the IAA (Internationale Automobil-Ausstellung (International Automobile Exhibition)) used for the Frankfurt Motor Show.

The brief gestation period was impressive but there were teething problems.  The fundamentals, the 908-based space-frame and the 4.5 (275 cubic inch) litre air-cooled flat-12 engine (essentially, two of Porsche’s 2.25 (137 cubic inch) litre flat-sixes joined together) were robust and reliable from the start but, the sudden jump in horsepower (HP) meant much higher speeds and it took some time to tame the problems of the car’s behaviour at high-speed.  Aerodynamics was then still an inexact science and the maximum speed the 917 was able to attain on Porsche’s test track was around 180 mph (290 km/h) but when unleashed on the circuits with long straights where over 200 mph (320 km/h) was possible the early 917s proved highly unstable, the tail “wandering from side-to-side” something disconcerting at any speed but beyond 200 mph, frightening even for professional race drivers.

On Mulsanne Straight, Le Mans: The slippery 917 LH (left) which proved "unsafe at high speed" (left) and the (slightly) slower 917 K (right) which, in the hands of experts), was more manageable.

The instability needed to be rectified because the 917 had been designed with "a bucket of Deutsche Marks in one hand and a map of the Le Mans circuit in the other" and these were the days before the FIA (Fédération Internationale de l'Automobile (International Automobile Federation and world sport's dopiest regulatory body)) started insisting chicanes be spliced into any straight where high speeds beckoned and the Mulsanne Straight at Le Mans was then an uninterrupted 6 km (3.7 mile) straight line.  There, the test results and slide-rule calculations predicted, the 917s would achieve in excess of 360 km/h (224 mph).  Serendipitously, physics and nature combined to show the team where the problem lay: After one alarming high speed run, it was noticed that while the front and central sections of the bodywork were plastered with bloodied snarge, the fibreglass of the rear sections remained a pristine white, the obvious conclusion drawn that while the airflow was inducing the desired degree of down-force on the front wheels, it was passing over the rear of body, thus the lift which induced the wandering.  Some rapid improvisation with pieces of aluminium and much duct tape (to this day a vital tool in the business) to create an ad-hoc, shorter, upswept tail transformed the behaviour and was the basis for what emerged from the factory's subsequent wind-tunnel testing as the 917 K (K for Kurzheck (short-tail).  The rest is history.

Dodge Public Relations announces the world now has "spoilers".  Actually they'd been around for a while but, as Dodge PR knew, until it happens in America, it hasn't happened.

What happened to the 917 wasn’t novel.  In 1966, Dodge had found the slippery shape of its new fastback Charger had delivered the expected speed on the NASCAR ovals but it came at the cost of dangerous lift at the rear, drivers’ graphically describing the experience at speed as something like “driving on ice”.  The solution was exactly what Porsche three years later would improvise, a spoiler on the lip of the trunk (boot) lid which, although only 1½ inches (38 mm) high, at some 150 mph (240 km/h) the fluid dynamics of the air-flow meant sufficient down-force was generated to tame the instability.  Of course, being NASCAR, things didn’t end there and to counter the objection the spoiler was a “non-stock” modification and thus not within the rules, Dodge cited the “safety measure” clause, noting an unstable car on a racetrack was a danger to all.  NASCAR agreed and allowed the device which upset the other competitors who cited the “equalization formula clause” and demanded they too be allowed to fit spoilers.  NASCAR agreed but set the height at maximum height at 1½ inches and specified they could be no wider than the trunk lid.  That left Dodge disgruntled because, in a quirk of the styling, the Charger had a narrower trunk lid than the rest of the field so everybody else’s spoilers worked better which seemed unfair given it was Dodge which had come up with the idea.  NASCAR ignored that objection so for 1967 the factory added to the catalogue two small “quarter panel extensions” each with its own part number (left & right); once installed, the Charger gained a full-width spoiler.

Quadraphonic

Quadraphonic (pronounced kwod-ruh-fon-ik)

(1) Of, noting, or pertaining to the recording and reproduction of sound over four separate transmission or direct reproduction channels instead of the customary two of the stereo system.

(2) A quadraphonic recording.

(3) A class of enhanced stereophonic music equipment developed in the 1960s.

1969: An irregular formation of quadra, a variant (like quadru) from the older Latin form quadri- (four) + phonic from the Ancient Greek phonē (sound, voice).  All the Latin forms were related quattor (four) from the primitive Indo-European kwetwer (four).  Phonē was from the primitive Indo-European bha (to speak, tell, say) which was the source also of the Latin fari (to speak) and fama (talk, report).  Phonic, as an adjective in the sense of “pertaining to sound; acoustics" was used in English as early as 1793. Those for whom linguistic hygiene is a thing approved not at all of quadraphonic because it was a hybrid built from Latin and Greek.  They preferred either the generic surround sound which emerged later or the pure Latin lineage of quadrasonic (sonic from sonō (make a noise, sound)) which appeared as early as 1970 although it seems to have been invented as a marketing term rather than by disgruntled pedants.  Quadraphonic, quadrasonic and surround sound all refer to essentially the same thing: the reproduction of front-to-back sound distribution in addition to side-to-side stereo.  In live performances, this had been done for centuries and four-channel recording, though not mainstream, was by the 1950s, not uncommon.  Quadraphonic is and adjective but had been used as a noun; the (equally irregular) noun plural is quadraphonics.

Surround sound

Quadraphonic was an early attempt to mass-market surround sound.  It used four sound channels with four physical speakers intended to be positioned at the four corners of the listening space and each channel could reproduce a signal, in whole or in part, independent of the others.  It was briefly popular with manufacturers during the early 1970s, many of which attempted to position it as the successor to stereo as the default standard but consumers were never convinced and quadraphonic was a commercial failure, both because of technical issues and the multitude of implementations and incompatibilities between systems; many manufacturers built equipment to their own specifications and no standard was defined, a mistake not repeated a generation later with the CD (compact disc).  Nor was quadraphonic a bolt-on to existing equipment; it required new, more expensive hardware.

Quadraphonic audio reproduction from vinyl was patchy and manufacturers used different systems to work around the problems but few were successful and the physical wear of vinyl tended always to diminish the quality.  Tape systems also existed, capable of playing four or eight discrete channels and released in reel-to-reel and 8-track cartridge formats, the former more robust but never suited to the needs of mass-market consumers.  The rise of home theatre products in the late 1990s resurrected interest in multi-channel audio, now called “surround sound” and most often implemented in the six speaker 5.1 standard.  Modern electronics and the elimination of vinyl and tape as storage media allowed engineers to solve the problems which beset quadraphonic but there remain audiophiles who insist, under perfect conditions, quadraphonic remains the superior form of audio transmission for the human ear.

First commercially available in 1965, the eight-track cartridge format (which would later become the evil henchman of quadraphonic) convinced manufacturers it was the next big thing and they rushed to mass-production and one genuine reason for the appeal was that the 8-track cartridge was the first device which was practical for use as in-car entertainment.  During the 1950s, the US car industry had offered the option of record players, neatly integrated into the dashboard and in the relatively compact space of a vehicle's interior, the sound quality could be surprisingly high.  Although not obviously designed with acoustic properties optimized for music, the combination of parallel flat surfaces, a low ceiling and much soft, sound absorbing material did much to compensate for the small size and range offered by the speakers.  However, although they worked well when sitting still in showroom or in certain vehicles, on the road things could be different.  The records (the same size as the classic 7 inch (180 mm) 45 rpm "singles") played by means of a stylus (usually called "the needle") which physically traced the grooves etched into the plastic disks rotating at 16.66 rpm which, combined with an etching technique called "ultra micro-grooving" meant the some 45 minutes of music were available, a considerable advance on the 4-5 minutes of the standard single.  The pressings were also thicker than other records, better to resist the high temperatures caused by heat-soak from the engine and the environment although, in places like Arizona, warping was soon reported.  To keep the stylus in the track, the units were fitted with a shock-absorbing, spring enclosure and a counterweighted needle arm.  Improbably, in testing, the system performed faultlessly even under the most adverse road conditions so the designers presented the product for corporate approval.  At that point there was a delay because the designers worked for the Colombia Broadcasting Corporation (CBS) which had affiliations with thousands of radio stations all over the country and no wish to cannibalize their own markets; if people could play records in their cars, the huge income stream CBS gained from advertising would be threatened as drivers tuned out.  The proposal was rejected.

Highway Hi-Fi record player in 1956 Plymouth.

Discouraged but not deterred, the engineers went to Detroit and demonstrated the players to Chrysler which had their test-drivers subject the test vehicles to pot-holes, railway tracks and rolling undulations.  The players again performed faultlessly and Chrysler, always looking for some novelty, placed an order for 18,000, a lucrative lure which convinced even CBS to authorize production, their enthusiasm made all the greater by the proprietary format of the disks which meant CBS would be the exclusive source.  So, late in 1956, Chrysler announced the option of "Highway Hi-Fi", a factory-installed record player mounted under the car's dashboard at a cost of (US$200 (some US$1750 in 2023 terms)).  Highway Hi-Fi came with six disks, the content of which reflected the reactionary tastes of CBS executives and their desire to ensure people still got their popular music from radio stations but the market response was positive, Chrysler selling almost 4000 of the things in their first year, the early adopters adopting with their usual alacrity.

The second generation of players used standard 45 rpm singles: Austin A55 Farina (left) and George Harrison's (1943–2001) Jaguar E-Type S1 (right); all four Beatles had the players fitted in their cars and lead guitarist Harrison is pictured here stocking his 14-stack array.  The lady on the left presumably listened to different music than the Beatle on the right (although their in-car hardware was identical) but tastes can't always be predicted according to stereotype; although he disapproved of most modern music, Rudolf Hess (1894–1987; Nazi deputy Führer 1933-1941) told the governor of Spandau prison (where he spent 40 of his 46 years in captivity) he enjoyed The Beatles because their tunes "were melodic".  

At that point, problems surfaced.  Tested exclusively in softly-sprung, luxury cars on CBS's and Chrysler's executive fleets, the Highway Hi-Fi had to some extent been isolated from the vicissitudes of the road but when fitted to cheaper models with nothing like the same degree of isolation, the styluses indeed jumped around and complaints flowed, something not helped by dealers and mechanics not being trained in their maintenance; even to audio shops the unique mechanism was a mystery.  Word spread, sales collapsed and quietly the the option was withdrawn in 1957.  The idea however didn't die and by the early 1960s, others had entered the field and solved most of the problems, disks now upside-down which made maintaining contact simpler and now standard 45 rpm records could be used, meaning unlimited content and the inherent limitation of the 4 minute playing time was overcome with the use of a 14-disk stacker, anticipating the approach taken with CDs three decades later.  Chrysler tried again by the market was now wary and the option was again soon dropped.

Clearly though, there was demand for in-car entertainment, the content of which was not dictated by radio station programme directors and for many there were the additional attractions of not having to endure listening either to advertising or DJs, as inane then as now.  It was obvious to all tape offered possibilities but although magnetic tape recorders had appeared as early as 1930s, they were bulky, fragile complicated and expensive, all factors which mitigated against their use as a consumer product fitted to a car.  Attention was thus devoted to reducing size and complexity so the tape could be installed in a removable cartridge and by 1963, a consortium including, inter alia, Lear, RCA, Ford & Ampex had perfected 8-track tape which was small, simple, durable and able to store over an hour of music.  Indeed, so good was the standard of reproduction that to take advantage of it, it had to be connected to high quality speakers with wiring just as good, something which limited the initial adoption to manufacturers such as Rolls-Royce and Cadillac or the more expensive ranges of others although Ford's supporting gesture late in 1965 of offering the option on all models was soon emulated.  Economies of scale soon worked its usual wonders and the 8-track player became an industry standard, available even in cheaper models and as an after-market accessory, some speculating the format might replace LP records in the home.

That never happened although the home units were widely available and by the late 1960s, the 8-track was a big seller for all purposes where portability was needed.  It maintained this position until the early 1970s when, with remarkable suddenness, it was supplanted the the cassette, a design dating from 1962 which had been smaller and cheaper but also inferior in sound delivery and without the broad content offered by the 8-track supply system.  That all changed by 1970 and from that point the 8-track was in decline, reduced to a niche by late in the decade, the CD in the 1980s the final nail in the coffin although it did for a while retain an allure, Jensen specifying an expensive Lear 8-track for the Interceptor SP in 1971, despite consumer reports at the time confirming cassettes were now a better choice.  The market preferring the cheaper and conveniently smaller cassette tapes meant warehouses were soon full of 8-track players and buyers were scarce.  In Australia, GMH (General Motor Holden) by 1975 had nearly a thousand in the inventory which also bulged with 600-odd Monaro body-shells, neither of which were attracting customers.  Fortunately, GMH was well-acquainted with the concept of the "parts-bin special" whereby old, unsaleable items are bundled together and sold at what appears a discount, based for advertising purposes on a book-value retail price there’s no longer any chance of realizing.

1976 Holden HX LE

Thus created was the high-priced, limited edition Holden LE (not badged as a Monaro although it so obviously looked like one that they've never been known as anything else), in "LE Red" (metallic crimson) with gold pin-striping, Polycast "Honeycomb" wheels, fake (plastic) burl walnut trim, deep cut-pile (polyester) carpet and crushed velour (polyester) upholstery with plaid inserts over vinyl surrounds in matching shades; in the 1970s, this was tasteful.  Not exactly suited to the image of luxury were the front and rear spoilers but they too were sitting unloved in the warehouse so they became part of the package and, this being the 1970s, rear-seat occupants got their own cigar lighter, conveniently located above the central ashtray.  Not designed for the purpose, the eight-track cartridge player crudely was bolted to the console but the audio quality was good and five-hundred and eighty LEs were made, GMH pleasantly surprised at how quickly they sold.  When new, they listed at Aus$11,500, a pleasingly profitable premium of some 35% above the unwanted vehicle on which it was based.  These days, examples are advertised for sale for (Aus$) six-figure sums but those who now buy a LE do so for reasons other than specific-performance.  Although of compact size (in US terms) and fitted with a 308 cubic inch (5.0 litre) V8, it could achieve barely 110 mph (175 km/h), acceleration was lethargic by earlier and (much) later standards yet fuel consumption was very high; slow and thirsty the price to be paid for the early implementations of the emission control devices bolted to engines designed during more toxic times.

1976 Holden HX LE Polycast "Honeycomb" wheel (14 x 7").

The Polycast process used a conventional steel wheel with a decorative face of molded polyurethane, attached with mechanical fasteners or bonded using adhesives (in some, both methods were applied) and although some snobs still call them "fake alloy" wheels, legitimately, they're a category of their own.  Because the rubbery, molded plastic fulfilled no structural purpose, designers were able to create intricate shapes which would then have been too delicate or complex to render (at an acceptable cost) in any sort of metal.  By consensus, some of the Ploycast wheels were among the best looking of the decade and, unstressed, they were strong, durable and long-lasting while the manufacturers liked them because the tooling and production costs were much lower than for aluminium or magnesium-alloy.  Another benefit was, being purely decorative (essentially a permanently attached wheelcover), their use faced no regulatory barriers; US safety rules were even then strict and Citroën at the time didn't both seeking approval for the more exotic "resin" wheels offered in Europe on the SM).

Aftermath of the pace car crash, Indianapolis 500, 29 May 1971; dozens were injured but there were no fatalities, despite impact with the well-populated camera stand being estimated at 60 mph (100 km/h).

The Holden LE's wheels came straight from the Pontiac parts bin in the US where they'd first appeared on the 1971 Firebird Trans-Am.  The concept proved popular with manufacturers and a set of Motor Wheels' "Exiter" (14" x 7", part number 36830 and advertised also as "Exciter") was fitted to the Dodge Challenger Pace car which crashed during the 1971 Indianapolis 500.  The crash was unrelated to the wheels, the driver (one of the Dodge dealers providing the pace car fleet) blaming the incident on somebody moving the traffic cone he'd used in practice as his pit-lane braking marker.    Motor Wheel's advertising copy: “What wheel can survive this beating?” and “...the new wheel too tough for the 'mean machine'” predated the crash at Indianapolis and was intended to emphasise the strength of the method of construction.

Twenty years on, the “parts bin special” idea was a part of local story-telling.  Although most doubt the tale, it's commonly recounted the 85 HSV VS GTS-R Commodores Holden built in 1996 were all finished in the same shade of yellow because of a cancelled order for that number of cars in "taxi spec", the Victorian government having mandated that color for the state's cabs.  While a pleasing industry myth, most suspect it's one of those coincidences and the government's announcement came after the bodies for the GTS-R had already been painted.  Being "taxi yellow" doesn't appear to have deterred demand and examples now sell for well into six figures (in Aus$).      

1971 Holden HQ Monaro LS 350

The overwrought and bling-laden Holden LE typified the tendency during the 1970s and of US manufacturers and their colonial off-shoots to take an elegant design and, with a heavy-handed re-style, distort it into something ugly.  A preview of the later “malaise era” (so named in the US for many reasons), it was rare for a facelift to improve the original.  The HQ Holden (1971-1974) was admired for an delicacy of line and fine detailing; what followed over three subsequent generations lacked that restraint although to be fair, while the last of the series (HZ, 1977-1980) ascetically wasn't as pleasing as the first, dynamically, it was much-improved.   

1973 Ford Falcon XA GT Hardtop (RPO83).

In the era of the LE, Ford Australia had it's own problem with unwanted two-door bodyshells.  Released too late to take advantage of what proved a market fad, Ford’s Falcon Hardtops (XA; 1972-1973, XB; 1973-1976 & XC; 1976-1979) never enjoyed the success of Holden’s Monaro (1968-1976), Chrysler’s Valiant Charger (1971-1978) or even that of Ford’s own, earlier Falcon Hardtop (XM; 1964-1965 & XP; 1965-1966).  The public’s increasing and unpredicted uninterest in the style meant that by 1976, like Holden, Ford had languishing in unwanted in their hands hundreds of body-shells for the big (in Australian terms although in the US they would have been classed “compacts”) coupés.  When released in 1972 Ford’s expectation was it would every year sell more than 10,000 Hardtops but that proved wildly optimistic and not even discounting and some “special editions” did much to stimulate demand.  By 1977 sales had dropped to a depressing 913 and with over 500 bodies in stock, the projection no more than 100 would attract buyers meant a surplus of 400; an embarrassing mistake.

Edsel Ford II with Falcon Cobra #001, publicity shot, Ford Australia's Head Office, Campbellfield, Victoria.  The badge below the Cobra decal reads 5.8; Australia switched to the metric system in 1973 but because of the nature of the machines, almost always the V8s are described either as 302 (4.9) or 351 (5.8), cubic inches being a muscle car motif. 

Scrapping them all had been discussed but in Australia at the time was Edsel Ford II (b 1948), great-grandson of Henry Ford (1863-1947), grandson of Edsel Ford (1893–1943) and the only son of Henry Ford II (1917–1987).  The scion had been sent to southern outpost to learn the family business and been appointed assistant managing director of Ford Australia; his solution profitably to shift the surplus hardtops was hardly original but, like many sequels, it worked.  What Edsel Ford suggested was to use the same approach which in 1976 had been such a success when applied in the US to the Mustang II (1973-1978): Create a dress-up package with the motifs of the original Shelby Mustangs (1965-1968), the most distinctive of which were the pair of broad, blue stripes running the vehicle’s full length.  In truth, the stripes had been merely an option on the early Shelby Mustangs but so emblematic of the breed did they become it’s now rare to see one un-striped.  The blinged-up Mustang IIs had been dubbed “Cobra II” and although mechanically unchanged, proved very popular.  One (unverified) story which is part of industry folklore claims the American’s suggestion was initially rejected by local management and discarded before a letter arrived from Ford’s Detroit head office telling the colonials that if Edsel Ford II wanted a Falcon Cobra with stripes, it must be done.  As Edsel's father once told a Lee Iacocca (1924–2019) who seemed to be getting ideas above his station: "Don't forget my name is on the building". 

Falcon Cobra #31.  The rear-facing bonnet (hood) scoop was the most obvious visual clue identifying the Option 97 (#002-031) cars although the after market responded and it became possible to buy replica scoops as well as the decals and plaques for those who wanted their own "Cobra look".

The Australian cars thus came to be “Cobra” and as well as providing a path to monetizing what had come to be seen as dead stock, the cars would also be a platform with which Ford could homologate some parts for use in racing.  The latter task was easy because in November 1977 Ford had built 13 “special order” XC Hardtops which conformed with the “evolution” rules of the Confederation of Australian Motor Sport (CAMS, then the regulatory body) for homologating parts for Group C touring car events.  Cognizant of the furore which had erupted in 1972 when high-output engines were homologated in road cars, the changes were mostly about durability and included enlarged rear wheel wells to accommodate wider wheels and tyres, a reverse hood (bonnet) scoop which drew desirable cool-air from the low-pressure area at the base of the windscreen, twin electric fans (switchable from the cockpit) which replaced the power-sapping engine-driven fan, a front tower brace (K-brace) which stiffened the body structure, an idler arm brace and front and rear spoilers.

Falcon Cobra #094 which was one of the "fully optioned" of the Option 96 build (#081-200 including the 351 V8, air-conditioning, power steering & power windows).

A prototype Falcon Cobra was built in April 1978 with production beginning the following July.  Unusually, all were originally painted Bold Blue before the areas which would become the stripes and the sill & wheel-arch highlights was masked with a coating of Sno White was painted over the top (thin Olympic (Blaze) Blue accent stripes separated the colors and “Cobra” decals were fitted to the sides and rear).  Each of the 400 built was fitted with a sequentially numbered plaque (001 to 400) on the dash and the production breakdown was:

#001: Created for promotional use, it was allocated for the photo-sessions from which came the images used in the first brochures (351 automatic).

#002-031: The Option 97 run which contained the parts and modifications intended for competition and produced in conformity with CAMS’s “evolution” rules (351 manual).

#032-041: 351 manual with air-conditioning (A/C) & power steering (P/S).

#042-080: 351 manual with A/C, P/S & power windows (P/W).

#081-200: 351 automatic with A/C, P/S & P/W.

#201-300: 302 manual.

#301-360 (except 351): 302 automatic with A/C & P/S.

#351: 351 manual.

#361-400: 302 automatic with A/C, P/S & P/W.

Moffat Ford Dealers team cars in the Hardie-Ferodo 1000 at Bathurst, finishing 1-2 in 1977 (left) and on the opening lap in 1978 (right).  In 1978, the cars (actually 1976 XB models modified to resemble XCs) matched their 1977 qualifying pace by starting second & third on the grid but in the race both recorded a DNF (did not finish). 

The Option 97 run (#002-031) included the modifications fitted to the 13 cars built in November 1997 but also included was engine & transmission oil coolers, a tramp rod (fitted only to the left-side because most racing in Australia is on anti-clockwise circuits and most turns thus to the left) and a special front spoiler which directed cooling air to the front brakes.  Visually, the Option 97 run was differentiated from the rest by the (functional) bonnet scoop and a pair of Scheel front bucket seats (part number KBA90018) in black corduroy cloth. Collectively, the 370 Option 96 and 30 Option 97 made up the 400 SVP (Special Value Pack) that was the Falcon Cobra.  The Cobra’s blue & white livery appeared on the race tracks in 1978 but the best known (the pair run by Allan Moffat's (v 1939) “Moffat Ford Dealers” team were actually modified XB Hardtops built in 1976 and the same vehicles which had completed the photogenic 1-2 at Bathurst in 1977.
