Foxbat

Foxbat or fox-bat (pronounced foks-bat)

(1) As Foxbat, the NATO (North Atlantic Treaty Organization) reporting name for the Soviet-era MiG-25 (Mikoyan-Gurevich MiG-25) high-altitude supersonic interceptor and reconnaissance aircraft.

(2) A common name for members of the Megachiroptera (the Pteropus (suborder Yinpterochiroptera), a genus of megabats), some of the largest bats in the world.

Fox is from the Middle English fox, from the Old English fox (fox), from the Proto-West Germanic fuhs, from the Proto-Germanic fuhsaz (fox), from the primitive Indo-European púḱsos (the tailed one), derive possibly from puḱ- (tail).  It was cognate with the Scots fox (fox), the West Frisian foks (fox), the Fering-Öömrang North Frisian foos, the Sölring and Heligoland fos, the Dutch vos (fox), the Low German vos (fox), the German Fuchs (fox), the Icelandic fóa (fox), the Tocharian B päkā (tail, chowrie), the Russian пух (pux) (down, fluff), the Sanskrit पुच्छ (púccha) (source of the Torwali پوش‎ (pūš) (fox) and the Hindi पूंछ (pūñch) (tai”).

Bat in the context of the animal was a dialectal variant (akin to the dialectal Swedish natt-batta) of the Middle English bake & balke, from the North Germanic. The Scandinavian forms were the Old Swedish natbakka, the Old Danish nathbakkæ (literally “night-flapper”) and the Old Norse leðrblaka (literally “leather-flapper”).  The Old English word for the animal was hreremus, from hreran (to shake) and it was known also as the rattle-mouse, an old dialectal word for "bat", attested from the late sixteenth century.  A more rare form, noted from the 1540s, was flitter-mouse (the variants were flinder-mouse & flicker-mouse) in imitation of the German fledermaus (bat) from the Old High German fledaron (to flutter).  In Middle English “bat” and “old bat” were used as a (derogatory) term to describe an old woman, perhaps a suggestion of witchcraft rather than a link to bat as "a prostitute who plies her trade by night".  It’s ancient slang and one etymologist noted the French equivalent hirondelle de nuit (night swallow) was "more poetic".  To “bat the eylids” is an Americanism from 1847, an extended of the earlier (1610s) meaning "flutter (the wings) as a hawk", a variant of bate.  Fox-bat is a noun; the noun plural is fox-bats.  When used of the MiG-25 (as "Foxbat", the NATO reporting name), it's a proper noun and thus used with an initial capital.

Fox-bat in flight.

The term fox-bat or flying fox, (genus Pteropus), covers some sixty-five bat species found on tropical islands from Madagascar to Australia and north through Indonesia and mainland Asia.  Most species are primarily nocturnal and are the largest bats, some attaining a wingspan of 5 feet (1.5 m) with an overall body length of some 16 inches (400 mm).  Zoologists list fox-bats as “Old World fruit bats” (family Pteropodidae) that roost in large numbers and eat fruit and are thus a potential pest, many countries restricting their importation.  Like nearly all Old World fruit bats, flying foxes use sight rather than echolocation, a physiological process for locating distant or invisible objects (such as prey) by means of sound waves reflected back to the emitter by the objects) to navigate, despite the largely nocturnal habit of most species.  In the database maintained by the International Union for Conservation of Nature and Natural Resources (IUCN), about half of all flying fox species are listed as suffering declining populations, 15 said to be vulnerable and 11 endangered. The fox-bats were previously classified in the suborder Megachiroptera, but most researchers now place them in the suborder Yinpterochiroptera, which also contains the superfamily Rhinolophoidea, a diverse group that includes horseshoe bats, trident bats, mouse-tailed bats, and others.

MiG-25 (Mikoyan-Gurevich MiG-25).

Once the most controversial fighter in the skies, there was so much mystery surrounding the MiG-25 that US, British and NATO planners spent years spying on it with a mixture of awe and dread.  Conceived originally by Soviet designers to counter the threat posed by Boeing’s B-70 Valkyrie bomber, development continued even after the B70 project, rendered redundant by advances in missile technology, was cancelled.  First flown in 1964 and entering service in 1970, nearly 1200 were built and were operated by several nations as well as the USSR.  Able (still) to outrun any other fighter, only the US Lockheed SR-71 Blackbird was faster but fewer than three dozen of those were built and those were configured only for strategic reconnaissance.  When first the West became aware of the Foxbat, it caused quite a stir because, combining stunningly high speed with high altitude tolerance and a heavy weapons load, it did appear to be the long-feared platform which would render Soviet airspace immune from US penetration.  It was the threat the Foxbat was thought to pose which was influential in the direction pursued by US engineers when developing the McDonnell Douglas F15.

The Foxbat however never realized its apparently awesome implications. Because the original design brief was to produce a device which could combat the fast, high-flying B-70, many of the characteristics desirable in a short-range interceptor were neglected in the quest for something which could get very high, very quickly.  At that it was a breathtakingly successful but there were compromises, the fuel burn was epic and, with a very high take-off and landing speed, it could operate only from the longest runways.  Still, at what it was good at it was really good and its very presence meant the US had to plan any mission within range of a Foxbat, cognizant of the threat it was thought to present.  Unbeknown to the West, at lower altitudes it presented little threat and was no dog-fighter; it was essentially a dragster built for the skies, faster in a straight line than just about anything but really not good at turning.  Its design philosophy was essentially the same as the Lockheed F-104 Starfighter, a US supersonic interceptor which first flew in 1954 with over 2,500 built and supplied to many air forces, the last of which wasn’t retired from active service until 2004.  An uncompromising machine built for speed, pilots dubbed it the “winged missile” and that assessment was not unrelated to it later gaining the nickname “widow-maker”; those who flew the thing described the characteristics it exhibited in low speed turns as: “banking with intent to turn”.

It wasn’t until 1976 when a Soviet defector landed a new Foxbat in Japan in 1976 that US engineers were able to examine the airframe and draw an understanding of its capabilities.  What their analysis found was that the limitations in Soviet metallurgy and manufacturing techniques had resulted in a heavy airframe, one which really couldn’t maneuver at high speeds, and handled poorly at low altitudes. The surprisingly primitive radar was of limited effectiveness in conventional combat situations against enemy fighters, which, combined with the low altitude clumsiness meant that its drawbacks tended to outweigh the advantage it had in sheer speed at altitude, something which meant less to the US since missiles had replaced the B-70 strategic bomber (which never entered production).

In its rare combat outings, those advantages did however confer the occasional benefit.  In 1971, a Soviet Foxbat operating out of Egypt used its afterburners to sustain Mach 3 for an extended duration, enabling it to outrun three pursuing Israeli F4-Phantoms and one downed a US Navy F/A-18 Hornet during the first Gulf War (1991).  During the Iran-Iraq War (1980-1988), the Iraqi Air Force found them effective against old, slow machinery but sustained heavy losses when confronted with the Iran’s agile F-14 but most celebrated was probably the Foxbat’s success during the Gulf War in claiming both of the last two American aircraft lost in air-to-air combat.  Otherwise, the Foxbat has at low altitude proved vulnerable, the Israeli Defense Force (IDF) shooting down several in the war over Lebanon (1981) although they have of late been used, most improbably, in a ground attack role in the Syrian Civil War, the Syrian Arab Air Force, lacking a more appropriate platform, pressing the Foxbats into a ground support role, in at least one case using air-to-air missiles to attack ground targets.  The Soviet designers took note of the operating environment when developing the Foxbat’s successor, the MiG-31 (NATO reporting name Foxhound), a variant which sacrificed a little of the pure speed and climb-rate in order to produce a better all-round fighter.

Usually unrelated: 1957 Morris Minor Traveller (left) and 1960 Jaguar XK150 FHC (right).  Stations wagons with wood frames (real and fake) are in the US called "woodies" but the spelling "woody" also appears in UK use.  Although between 1968-1973, there were “badge-engineered” Versions of the Minor’s commercial derivatives sold as the Austin 6cwt & 8cwt Van & Pick up, all the “woodies” were Morris Travellers.

Although for the whole of the Jaguar XK150’s production run (1957-1961) the Morris Minor Traveller (1952-1973) was also being made in factories never more than between 20-60 odd miles (32-100 km) distant, so different in form and function were the two it’s rare they’re discussed in the same context.  One was powered by an engine which had five times won the Le Mans 24 hour endurance classic while the other was one of several commercially-oriented variants of a small, post-war economy car, introduced in the austere England of 1948.  The Traveller did however have charm and it was also authentic in its construction, the varnished ash genuinely structural, an exoskeleton which provided the strength while the panels behind were there just to keep out the rain.  By contrast, by the mid-1950s, the US manufacturers had abandoned the method and produced “woodies” with a combination of fibreglass (fake timber) and DI-NOC, (Diurno Nocturna, from the Spanish, literally “daytime-nighttime” and translated for marketing purposes as “beautiful day & night”) appliqué, an embossed vinyl or polyolefin material with a pressure-sensitive adhesive backing produced since the 1930s and perfected by Minnesota Mining & Manufacturing (3M).

In phased releases over 1957-1958, Jaguar made available the usual three versions of its XK sports car, the DHC (drophead coupé, a style which elsewhere was usually called a cabriolet or convertible) and FHC (fixed head coupé, ie coupé), later joined by the more minimalist OTS (open two-seater, a roadster) and the line was a link between flowing lines of the inter-war years and the new world, celebrated by the E-Type (1961-1974) which created such a sensation upon debut at the 1961 Geneva Motor Show.  One sometimes unappreciated connection between the XKs (XK120: 1948-1954, XK140: 1954-1957 & XK150: 1957-1961) and E-Type is neither was envisaged as the long-term model both became.  The XK120 had been shown at the 1948 London Motor show with the purpose of drawing attention to the new XK straight-six (which would serve in vehicles as diverse as racing cars, limousines and fire engines until 1992) but such was the public response it was added to the factory catalogue, the early models hurriedly built in aluminium to satisfy demand.  Later, Jaguar hadn't believed there would be a market for more than a few hundred E-Types so it was not designed in a way optimized for mass-production which was embarked upon only because demand was so high.  Many of the car's quirks and compromises remained part of the structure until the end of production more than a decade later.   

Minor modification: 1960 Jaguar XK150 3.4 Shooting Brake (“Foxbat”).

The Morris Minor Traveller was the last true woodie in production and is now a thing in the lower reaches of the collector market but there's one less available for fans because of a sacrifice to a project by industrial chemist and noted Jaguar enthusiast, the late Geoffrey Stevens, construction undertaken between 1975-1977. He wanted the Jaguar XK150 shooting brake the factory never made so blended an XK150 FHC with the rear compartment of a Morris Minor Traveller of similar vintage.  Mr Stevens in 1976 dubbed his creation “Foxbat” because, just as a MiG-25 landing in Japan was an event so unexpected it made headlines around the world, he suspected that in the circles he moved, a timber-framed XK150 shooting brake would be as much a surprise.  In that he proved correct and the unique shooting brake has been restored as a charming monument to English eccentricity, even the usually uncompromising originality police among the Jaguar community (mostly) fond of it.  In a nice touch (and typical of an engineer’s attention to detail), a “Foxbat” badge was hand-cut, matching the original Jaguar script.  Other than the hybrid coach-work, the XK150 is otherwise “matching-numbers” (chassis number S825106DN; engine number V7435-8).   

On the Wings of a Russian Foxbat: Deep Purple bootleg, 1977.

The origin of the term “bootlegging” dates from the late eighteenth century when it was used by British customs and excise officers to describe the trick smugglers used hiding valuables in their large sea-boots.  Since then, it’s been applied variously including (1) the distilling, transporting and selling of unlawful liquor (2) unlicensed copies of software and (3) unauthorized recordings of music and film.  In music, bootleg recordings began to appear in some volume in the 1960s and originally were often from live performances.  Often created from tapes of dubious quality with little or no editing, these bootlegs generally were tolerated by the industry because they tended to circulate among fans who anyway purchased the official product and were thought of just a form of free promotional material.  Later, when things became more organized and bootleggers began distributing replicas of official releases, the attitude changed and for decades the software industry fought ongoing battles against bootleg copies (which in some non-Western markets represented in excess of 90% of installations).

On the Wings of a Russian Foxbat, re-released (in re-mastered form with bonus tracks) in 1995 as Live in California, Long Beach Arena, 1976.

Taken from a performance by the English heavy metal band Deep Purple at the Long Beach Arena, Los Angeles on 27 February 1976, the bootleg On the Wings of a Russian Foxbat was released in 1977 and was another example of the effect on popular culture of the Soviet pilot’s defection.  The link with the event in Japan was that the quality of the band’s performance was unexpectedly good, their reputation at the time not good (they would break-up only weeks after the Long Beach show).  Additionally, the sound quality was outstanding (certainly by the usual bootleg standards), something not then easy to achieve in an outdoor venue with a raucous audience.  Curiously, the original On the Wings of a Russian Foxbat bootleg used for the cover art a picture of unsmiling soldiers from the PLA (People’s Liberation Army) from the Republic of China (then usually called “Red China” or “Communist China); presumably the bootleggers decided the star on the caps was “sufficiently Russian”.  In 1995, re-mastered, the recording (with a few bundled “extras”) was re-issued as an “official” release, the fate of many a bootleg with a cult-following.  With memories of the diplomatic incident in 1976 having faded, although On the Wings of a Russian Foxbat still appeared on the cover, the album was marketed as Live in California, Long Beach Arena, 1976.

Booby

Booby (pronounced boo-bee)

(1) A bird, a gannet of the genus Sula, having a bright bill, bright feet, or both; some are listed as threatened or endangered.

(2) A slang term for someone thought stupid or a dunce, ignorant or foolish (although still used in the mid-twentieth century, it's probably now obsolete, the meaning crowded out by intrusion of newer slang, some of which has also fallen victim to the linguistic treadmill).

(3) The losing player in a game (the historic UK usage "booby prize", now largely obsolete except in informal use).

(4) One of the many slang terms for the human female's breasts and related to the more common boob, boobs and boobie.

(5) In croquet, a ball that has not passed through the first wicket. 

1590s: From Spanish Latin from the earlier pooby, apparently a blend of (the now obsolete in this context) poop (to befool) and baby, perhaps by association with Spanish bobo (stupid person, slow bird), thought to be from an imitative root of the Latin balbus (stuttering).  Balbus was from the primitive Indo-European balb- & balbal- (tongue-tied) and was cognate with the Ancient Greek βαμβαίνω (bambaínō) & βαμβαλύζω (bambalúzō) (I chatter with the teeth), the Russian болтать (boltatʹ) (to chatter, to babble), the Lithuanian balbė́ti (to talk, to babble), the Sanskrit बल्बला (balbalā) (stammering) and the Albanian belbët (stammering).  The booby prize dates from 1883, a prize given to the loser in a game as concept which persists in some sporting competitions as "the wooden spoon", the idea being something as removed as possible from the usual silverware given as trophies.  The booby trap was first noted in 1850, originally a schoolboy prank (ie something only a "boob" would fall for); the more lethal sense developed during World War I and remain common military and para-military use.  Booby and boobyism are nouns, boobyish and (the non-standard but potentially useful)  boobyesque are adjectives; the noun plural is boobies.

Boobies: found usually in pairs

A nice pair of boobies.  Charmingly, blue-footed boobies are known to be monogamous, pairs often staying together for life.

A booby is a seabird in the genus Sula, part of the Sulidae family. Boobies are closely related to the gannets (Morus), which were formerly included in Sula, the genus created in 1760 by the French naturalist Mathurin Jacques Brisson (1723-1806).  The name is derived from súla, the Old Norse and Icelandic word for the other member of the family Sulidae, the gannet.  The English name booby was based on the Spanish bobo (stupid) as the tame birds often landed on board sailing ships, where they were easily captured and eaten.  As well as a popular addition to the diet of sailors for whom meat other than fish was a rarity, it was fortuitous for many, the Admiralty's archives revealing boobies are often mentioned as having been caught and eaten by shipwrecked sailors.  In taxonomic classification, variations include Abbott's booby (Papasula abbotti), blue-footed booby (Sula nebouxii), brown booby (Sula leucogaster), masked booby (Sula dactylatra), Nazca booby (Sula granti), Peruvian booby (Sula variegata), red-footed booby (Sula sula) & Tasman booby (Sula dactylatra tasmani).

One step at a time.

The distinctive blue feet (the result of pigments ingested from their diet of fish) also play a part in the bobby’s mating ritual although not exactly in the podophilic sense familiar in a sub-set of humans.  In the spring mating season, the bird’s feet become a bright turquoise blue and, to demonstrate their health and vitality conspicuously they will display them to potential partners.  The job done, as their eggs hatch, the blue hue fades to something less vivid.  One aspect of their behaviour which amused the ornithologists who first observed it was that if among fishers unloading their catch, it tossed a small fish from the by-catch, a booby will take it and waddled off somewhere to enjoy it in solitude rather than gulping it down as in common in many species.  Like penguins, although ungainly on land, they are skilled plunge divers which used their streamlined bodies and air sacs “fly” through the water, catching their prey at high speed and they hunt in "packs", coordinating their movement to maximize the catch.  Boobies have been recorded diving from as high as 90 m (300 feet), their speed upon entry estimated at around 100 km/h (60 mph).

Boobies in time, in step.

Based on the use by mainstream internet sites (including nominally reputable news organizations), boob (more commonly in the plural as boobs) seems to have emerged as the preferred slang for breasts, probably because it seems the term women find most acceptable and the one they most often use, not infrequently as their default descriptor.  The origin appears to lie in bubby (plural bubbies), a slang term for the female breast dating from the 1680s which is thought to be imitative of a baby's cry or the sucking sound heard during lactation.  It was most associated with south-east England although that may reflect more extensive documentation rather than proof of regionalism.  Inherently anyway a form in oral use, the alternative pronunciations included buhb-ee, boo-bee & boob-ee so the evolution to boob was perhaps not unexpected although most dictionaries list the earliest known instance as a late 1930s Americanism with the back-formed clippings boob & boobs not appearing until the early post-war years, initially as a vulgarism, women not embracing use for decades although that their approval seems to have coincided with late second-wave feminism is presumably coincidental.

In fashion, the boobie top (less commonly as booby-top) is a style of clothing (including dresses) which in some way draws attention to or emphasizes the breasts.  The design is most associated with generous displays of cleavage or skin but is used also to refer to garments which wholly cover the breasts in such as way as to highlight the size, shape or movement.  In the industry, a “boobie top” differs from a “boob tube” in that while the former seeks to highlight the breasts as a feature (either by using the fabric tightly to shift the focus to the size and shape or with a cut which displays the cleavage component of the décolletage) while a “boob tube” is a different interpretation of the minimalist: it completely envelopes the breasts (ie little or no visible cleavage) but otherwise exposes the torso.

A “tube top” in the original style (left) and a “boob tube” (right), both now likely to be advertised as a “boob tube”.

The style was in 1972 first described as a “tube-top” (strapless and extend from the armpits to the naval; such garments had earlier been available but the name was new) and the companion “tube skirt” appeared the next season (again, a re-labeling).  The first “boob tubes” were advertised in 1977 and the early were all a truncated version of the “tube top” in that they wrapped only around the breasts); inherently it was a midriff-baring creation and could be thought of as a kind of strapless, bandeau bra designed for outdoor wear (on warmer days).  Constructed with elasticized fabrics, they were designed to be worn without a bra but, like all forms of structural engineering, physics does limit what's possible and they came later to be available also with a “built in bra”.  Others just choose boob tubes made with a thicker material so a strapless bra unobtrusively could be worn beneath but, VBS (visible bra-straps) no longer being a sin against fashion, some now choose a to make the bra part of the look.  In truth, the terms “tube top” & “boob tube” were all a bit misleading because it was only the material covering the breasts which tended toward a truly tubular bra with the rest being more or less flat and a better description might have been “flange” but this wouldn’t have had the same appeal in a boutique so “tubes” they became.  In product descriptions, the distinction between “tube top” and “boob tube” quickly became blurred and the latter tends now often to be used of both types. 

US Army booby trap messaging, 1942.  Such infections have for centuries been a significant part of military medicine because STIs often would reduce unit strength (ie "battle-ready" troops).

During World War II (1939-1945), the US military kept up with evolution of slang, something reflected in advertising which lent a new definition to "booby trap", a familiar concept in which soldiers were well-drilled.  Despite the efforts of padres, it was rare for commanders to attempt to impose morality and when on deployment it was common for there to be "authorized" brothels (often separate facilities for officers and other ranks) with the prostitutes subject to regular inspection by medical staff and allowed to practice their ancient profession only if the supervising doctor issued a "clean" certificate.  Until well into the twentieth century (and the beginning of the antibiotic era), it wasn't unusual for the losses of combat-ready troops to illness & disease to exceed those caused by battlefield causalities and although the numbers were dwarfed by conditions such as malaria, preventing and treating sexually transmitted diseases (STDs, then called venereal disease (VD)) was an important component of military medicine.  It wasn’t until the 1970s the initialism VD began to be replaced by STD (VD thought to have to have gained too many specific associations) but fortunately for AT&T, in 1951 they renamed their STD (Subscriber Toll Dialing) service (for long-distance phone calls) to DDD (Direct Distance Dialing), apparently for no better reason than the alliterative appeal although it's possible they just wanted to avoid mentioning “toll” with all that implies.  Many countries in the English-speaking world continued to use STD for the phone calls, even after the public health specialists had re-purposed the initialization.  In clinical use, STI (Sexually Transmitted Infection) seems now the preferred term.

The other booby trap: Helpful advertising circa 1950.

In Western legal systems, two aspects of consumer protection which greatly advanced in the twentieth century were product liability and “truth in advertising”.  What the changes in product liability did was break the nexus of “privity of contract”, meaning it was no longer required that to seek redress or compensation, an injured party had to be the purchaser of the defective goods.  That reform took shape during the inter-war years but “truth in advertising”, although an old concept enforced in contract law, really became a movement in the post-war years; it was designed to remove from commerce “deceptive or misleading” claims although advertising agencies still had a wide scope to be “economical with the truth” if they could make their assertions fit into the “mere puffery” rubric.  One field never policed was women’s shapewear (corsets and such) which, with a judicious placement of struts, elasticized panels, ribs and padding could variously make body parts appear curvier, straighter, smaller, larger or higher.  The Wonderbra (and its many imitators) was probably the best known example because among the many garments and devices it was the one which most dramatically deceived and misled.  Of all this trickery the law remained silent and the sage advice remained: caveat emptor.

Pre 900: From the Middle English lepen, from the Old English hlēapan, from the Proto-West Germanic hlaupan, from the Proto-Germanic hlaupaną (a doublet of lope, lowp, elope, gallop, galop, interlope and loop).  It was cognate with the German laufen (to run; to walk), the Old Norse hlaupa the Gothic hlaupan, the West Frisian ljeppe (to jump), the Dutch lopen (to run; to walk), the Danish løbe and the Norwegian Bokmål løpe, from the primitive Indo-European klewb- (to spring; stumble) (and may be compared with the Lithuanian šlùbti (to become lame) & klùbti (to stumble).  The verb forms are tangled things.  The third-person singular simple present tense is leaps, the present participle leaping, the simple past leaped or leapt (lept & lope the archaic forms) and the past participle is leaped or leapt or (lept & lopen the archaic forms).  That leapt and leaped remain in concurrent use is another of those annoy things in English which are hangovers from their ancient entrenchments in regional use and, as a general principle leapt tends to be is preferred educated British English while leaped is seen more frequently in North America (although leapt is in those places not uncommon, especially in areas with historical ties to England).  The transitive sense as in “pass over by leaping” was in use by the early fifteenth century and there are references to the children’s game “leap-frog” documented in the 1590s, and so obvious was the use of that figuratively it probably quickly was adopted but the first attested entry dates from 1704.  The familiar “to leap tall buildings in a single bound” comes from the Superman comics of the 1940s although in idiomatic use, “leaps” has been paired with “bounds” since at least since 1720.  Leap is a noun, verb & adjective, leaper & leapling are nouns and leaping and leapt & leaped are verbs; the noun plural is leaps.

The leap year is “a year containing 366 days” and use dates from late fourteenth century Middle English lepe gere, a genuine innovation because no equivalent term existed in the Old English. The origin is thought to come from the effect of fixed festival days, which normally advance one weekday per year, to “leap” ahead one day in the week.  The Medieval Latin was saltus lunae (omission of one day in the lunar calendar every 19 years), the Old English form being monan hlyp.  The adjustments happened in the calendars of many cultures, always with the purpose of ensuring the man-made devices for tracking dates (and therefore time) remained consistent with the sun; summer needed always to feel like summer and winter like winter.  Different methods of handling the intercalary were adopted and in England the bissextile was the device.  The noun & adjective bissextile (plural bissextiles) dates from the early 1580s and was from the Latin bisextilis annus (bissextile year), the construct being bisextus + -ilis, deconstructed as bis- (two; twice; doubled) + sextus (sixth) + dies (day) and was a reference to the Julian calendar's original reckoning of its quadrennial intercalary day as a 48-hour 24 February (subsequently distinguished as the two separate days of the sixth day before the March calends (sexto Kalendas Martii) and the “doubled sixth day”.  In modern use, 24 February is now understood as “five days before 1 March” but in Roman use it was called “the sixth” because the counting of dates was then inclusive.

The most physically demanding (and dangerous) part of Lindsay Lohan’s impressive leap into a Triumph TR4 in Irish Wish was undertaken by a body double (the young lady in this case deserving the “stunt-double” title).

Ready to leap: Lindsay Lohan with stunt double Aoife Bailey (b 1999).

Lindsay Lohan's Netflix movie Irish Wish (2024) was said by Irish reviewers to be "a mix of Leap Year meets Just My Luck meets Freaky Friday in which Lohan stars as quiet book editor Maddie Kelly, who embarks on a journey to find love by learning to love herself first."  Like Irish Wish, Leap Year (2010) was filmed in Ireland but unlike 2010, 2024 was a leap year.  IMCDB’s (Internet Movie Cars Database) comprehensive site confirmed the Triumph TR4 was registered in Ireland (ZV5660, VIN:STC65CT17130C) as running the 2.1 litre version (17130C) of the engine.  The Triumph 2.1 is sometimes listed as a 2.2 because, despite an actual displacement of 2138 cm³; in some places the math orthodoxy is ignored and a "round up" rule applied, something done usually in jurisdictions which use displacement-based taxation or registration regimes, the "rounding up" sometimes having the effect of "pushing" a vehicle into a category which attracts a higher rate.  Those buying a TR4 for use in competitions with a 2.0 litre limit could specify the smaller unit from the factory but being based on a tractor engine (!) and thus fitted with wet-cylinder liners, “sleeving” a 2.1 back to 2.0 wasn’t difficult.  The lack of the "IRS" (independent rear suspension) badge on the trunk (boot) lid indicates the use of the live rear axle and that detail was of no significance in the plot although, given the leap scene, a convertible of some sort would have been required.  Although on the road the IRS delivered a smoother ride, those using TR4s in competition usually preferred the live rear-axle because it made the car easier to steer “with the throttle”.

The replacement of the bissextile by the then novel 29 February every four years-odd appears such an obviously good idea it seems strange it took centuries universally to be adopted in England although the documents reveal the shift was certainly well in progress by the mid-fifteenth century and in an echo of later practices, the more curmudgeonly the institution, the slower the intrusion of the new ways, the Admiralty and houses of parliament ignoring 29 February until well into the 1500s.  It wasn’t until the Calendar (New Style) Act (1750) passed into law that 29 February received formal recognition in UK law.  The reform worked well from the start but in some jurisdictions, government lawyers took no chances and for the handful of souls born on a 29 February, their birth dates were deemed to be 28 February or 1 March for all legal purposes (eligibility for drivers licenses or pensions, age of consent etc).  One born on 29 February is a “leapling” and there are said to be a few as five million of these lonely souls on the whole planet.  In many countries hospitals and midwives note the frequency with which expectant mothers approaching March request staff do whatever is required to avoid them giving birth to a leapling, fearing the child will feel deprived by having fewer birthdays than their siblings of friends.  The math of the leap year is it is one (1) evenly divisible by 4, (2) except for years are evenly divisible by 100 except that (3) years evenly divisible by 400 are leap years.  So, 2000 was while 1900 was not; 2100 will not be a leap year, but 2400 will be.  However, because the rotation of the Earth is changing (and thus the length of days), as is its distance from the Sun, even a 29 February now and then is not enough to keep everything in sync.  So, there are also leap seconds, spliced in as needed and unlike 29 February, only those dealing with atomic clocks and such notice addition.

Leap is common in idiomatic use:  To do something in “leaps and bounds” suggests commendably quick progress.  A “leap in the dark” is to take some action while being uncertain of consequences and the related “leap of faith” is trusting in something that cannot be seen or proven so in a sense they’re two ways of saying much the same thing although “leap of faith” does also imply some trust in something or someone.  To have one’s heart “leap into one’s throat” is an allusion to the sensation felt sometimes in the throat when something scary happens.  To “leap for joy” is much the same as “jump for joy” and describes joyous happiness.  To “leap at” something is enthusiastically to take up an offer, avail one’s self of an opportunity etc.  When doing so, one might be said to “leap into action”.  To be cautioned to “look before you leap” is to suggest one should be sure of things before doing something; if one ignores the advice then it’s a “leap of faith” or a “leap into the dark”.  To “leapfrog” is to skip a step in some process, the connotation almost always positive.  To suggest someone “take a flying leap” is much the same as telling them to “go jump in the lake” or, as is now more common: “fuck off”.  The concept of the "quantum leap" was in 1913 introduced (as the "quantum jump") by Danish physicist Niels Bohr (1885–1962) in his "Bohr model" of the atom.  In the strange world of quantum mechanics it describes the discontinuous change of the state of an electron in an atom or molecule from one energy level to another and was adopted figuratively to refer to an "abrupt, extreme change".  In modern use, it has come to mean a large or transformative change, a use to which pedants sometimes object but this is how the English language works.  The “leap year bug” is jargon rather than a idiom and describes the growing number of instances of problems caused by computers (and related machines) for whatever reason not correctly handling the existence of leap years.  Most are caused by human error and some are not being rectified because the original error has been built upon to such an extent that it’s easier to handle the bugs as they occur.  If something is said to be “a bit of a leap” or “quite a leap” it means there's some scepticism about the relationship one thing and another (often cause & effect). 

Jaguar's Leaper

The radiator cap of course began as a mere functional device which could be unscrewed to allow coolant to be added but, inevitably, possibilities occurred to stylists (they weren’t yet “designers”) and soon the things were a small platform for miniature (though many were anything but small) works of art to covey an image to suit at least what was imagined to be the character of the vehicle on which they sat.  Although such embellishments are now remembered for their decorative qualities (and many in the art deco era during the inter-war were lovely creations), some genuinely were functional and “topping-up” the coolant was for decades a frequent part of the motoring experience so, however attractive they may have been, their use as a handle means they may be thought architectonic as well as artistic. The Jaguar Leaper had fangs and while that sounds ominous for pedestrians, some of the radiator cap & hood emblems looked more lethal still and even before the “safety movement” of the 1960s, there had been discussions about the dangers they posed.  For the safety of pedestrians, the few survivors now are spring-loaded or retract when the vehicle is in motion.

Leaper on 1960 Jaguar Mark 2 3.8.  Owners found the fitting handy when opening the hood.

“Leaper” really was the factory’s name for the lunging feline figure which for decades adorned the space atop or behind the grill on many Jaguars.  The story of the origin is murky and while there may be some myth-making in it, the most likely explanation seems to be that when late in 1934 newly appointed Ernest William "Bill" Rankin (1898-1966, Advertising Manager and Public Relations Officer, Jaguar Cars 1934-1966) settled (from a list of charismatic wild animals) on “Jaguar” as a name for a new “sporty” SS (then the company name) car and, part of the “brand identity” was to design an appropriate radiator cap ornament.  Rankin was acquainted with the draftsman & technical illustrator Gordon Crosby (1885–1943) who he knew to be an amateur sculptor and it was to him the commission was granted.  Crosby delivered a prototype cast in bronze and according to company mythology, Jaguar’s founder, Sir William Lyons (1901–1985) thought it looked like “a cat shot off a fence” but liked the concept so, lengthened and softened into something sleeker, the refined shape emerged as the “Leaper”, first fitted in 1938.  The tales do differ, some suggesting Sir William’s “cat shot off a fence” thoughts were prompted by the sight of an earlier, third–party ornament which inspired him to task Mr Rankin with finding a replacement and, in the absence of documentary proof, Jaguar fans can pick the story they prefer.

Leaper on 1950 Jaguar Mark V 3.5.  The Mark V (1948-1951) was the last Jaguar with the external radiator cap and thus the last time a Leaper was also a cap-handle.

The SS name came from the Swallow Sidecar Company which Lyons had in 1922 co-founded with William Walmsley (1892–1961), reorganized as “S.S. Cars” after 1934 when Walmsley withdrew and the adoption in 1935 of “Jaguar” as a model name was mere marketing and nothing to do with the by then unsavoury reputation of the German SS (Schutzstaffel (protection squad), which began in 1923 as a small security guard for Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) but which evolved into a kind of parallel army for the Nazi Party and later into an armed formation almost a million-strong).  Even by 1945 when motor vehicle production resumed and the corporate name S.S. Cars formerly was changed to “Jaguar Cars Limited”, the rationale was the stronger brand identity of the latter rather than an aversion to anything associative with the Nazis.  Indeed, in 1957 Jaguar returned to SS as designation with the release of the XKSS, a road-going version of the Le Mans-winning D-Type race car.

An early Leaper (left) and the later "in flight" version (right) with the fully extended hind legs.

First fitted to production SS Jaguars in 1938, it became standard equipment on all until 1951 when the Mark V was discontinued.  As the last Jaguar to feature an external radiator cap, the assumption was that was the end of the Leaper and the strikingly modernist XK120 which created a sensation at the 1948 London Motor Show had only a radiator grill; the spirit of the age was that the ornaments were antiquated relics.  However, elsewhere in the industry, modernity and nostalgia managed peacefully to co-exist and while there was no revival of external radiator caps, the ornaments refused to die and from expensive Mercedes-Benz and Rolls-Royce to the most humble Austins and Chevrolets, the chromed constructions continued and sometimes grew, those not able to sit atop grills (many now with no “top” as such) re-imagined as hood (bonnet) ornaments.  So, in 1955 the Jaguar Leaper made a comeback on the new small saloon (the 2.4), the mascot using the subtle post-war re-working of the hind legs, made more outstretched to suggest the big cat in “mid-leap”, about to take its prey.

Rendered usually in fibreglass anodized with a shiny silver finish (although some, daringly, were gloss black), large leapers were often a feature of Jaguar dealerships (left).  Once decommissioned, they were sometimes sold and, applying dreadful and indefensible gender stereotyping, were a good gift for the garden (right) of the Jaguar-owning husband or boyfriend who "has everything". 

On the saloons, the design lasted 14 years and it was offered as an option on the XK150 (1957-1961) for while the XK120 (1948-1954) in 1948 had seemed streamlined modernity exemplified, the world had moved on and by 1957, although much improved and still stylish, the lines now seemed baroque rather than minimalist; the Leaper now fitted in well.  For the big Mark X saloon in 1961, paradoxically, a smaller Leaper was cast and this remained in use until the car (by then called 420G) was retired in 1970 so it was thus the last of the early Leapers, the XJ unadorned upon its debut in 1968 with the last of the legacy saloons (240, 340 (1967-1969 and both renamed and often de-contented versions of the Mark 2 (1959-1967)), S-Type (1963-1968) & 420 (1966-1968) produced in 1969.  The aftermarket though remained buoyant with many XJs and XJSs fitted with Leapers by owners who liked the look or dealers who thought they would.  It does seem they were fitted at the plant to many of the New Zealand-assembled XJs and the factory may have been in two minds about it: the hoods of all XJs (1968-1992) included on the underside skin- panel marks indicating where the holes should be drilled.  Not until the X300 XJ in 1994 would they again be factory-fitted to some models (in “pedestrian friendly” spring-loaded form) and this continued until 2005.

1958 Jaguar XK150 DHC (drop head coupé, left) and 1967 420G (right).

When in 1957 the Leaper appeared as an option on the XK150, Jaguar used the standard part fitted to the saloons but for the Mark X in 1961, a smaller version was cast, despite the car (stylistically something of a preview of the “fuselage” Chryslers of 1969) being the widest then produced in the UK (and it would remain so until 1992 when the company released the XJ220).  So, although the Leaper genuinely was smaller, the compression of relativities exaggerated the effect.  Jaguar took the opposite approach to Mercedes-Benz, the Germans creating a larger cartouche (the three-pointed star inscribed within a circle which sat atop the grill) for use on the big 600 Grosser (1963-1981).  What that did was maintain the relative dimensions familiar from the symbol’s use on smaller models.

Leaper on a US market 1999 Jaguar Vanden Plas (X308) which in the US market were fitted with the fluted grill used otherwise only on the Daimler variants.  The solid-timber picnic tables (a feature adored by the English middle class) were much admired.

The US market Vanden Plas models were the only Jaguars on which the Leaper was used in conjunction with the fluted grill fitted to the home market and RoW (rest of the world) Daimlers.  Because it was Mercedes-Benz and not Jaguar which after 1966 held the US rights to the Daimler brand, Daimlers since then sold in the US were badged as Jaguar Vanden Plas although they were otherwise identical to Daimlers including the fluted fittings.  The supercharged Daimler Vanden Plas was the most exclusive of the X308s and was noted for details such as the rear picnic tables being crafted from solid burl walnut timber rather than the veneer over plastic used on cheaper models.

1970 S2 Jaguar E-Type (top) from the "R2" run of 1000-odd (almost all of which were registered as 1971 models) with the Leaper badges on the flanks (left-side p/n BD35865 (left); right side p/n BD35866 (right)).  A Growler appeared in the front centre-bar (right).

The Series 2 E-Type (1968-1971) was marred by the clutter of bigger bumpers, protuberant headlight assemblies, badges and side-marker lights and so much did they detract from lovely, sleek lines of the Series 1 cars (1961-1967), bolting a luggage rack to the boot (trunk) lid probably seemed no longer the disfigurement it would once have been.  The disfigurement had begun with the transitional E-Types (the so-called 1.25 & 1.5 cars built in 1967) and indicate what would have been necessary to ensure post-1973 MGBs & MG Midgets conformed with the US headlight height stipulation.  It could have been done on the MGB but the shape of the Midget made the modification impossible (at least within aesthetic acceptability) but BL (British Leyland) took the cheaper route (always their preferred option) and raised the suspension height, compromising handling and lending the things a slight cartoonish quality but by then power had been so reduced by emission controls the view probably was handling prowess was no longer so important.  Remarkably, demand for both the by the antiquated MGB and Midget remained strong until sales finally ended in 1980.  The left-hand (left) and right-hand (right) fender badges, being directional, were different part numbers (BD35865 & BD35866 respectively) and those used on E-Types were silver on black whereas the variants used on the XJs were gold on black, some of which depicted the leaping feline at a slight slope, both matters of note for those wishing to restore cars to the challenging “factory original” standard.

1976 Jaguar XJC 4.2.

This XJC is one of many in the wild which, at some point, was fitted with a Leaper but it’s a shame whoever made the addition didn't at the same time remove the unfortunate vinyl roof.  Like the headlight covers sometimes added to the later (S1.25 & 1.5) S1 E-Types, removing an XJC's vinyl roof is one of the rare exceptions Jaguar's usually uncompromising originality police not only tolerate but encourage.  The Leaper badges on the flanks (behind the front wheel arch) were factory-fitted on the Series 1 (1968-1973) & Series 2 (1973-1979) XJs but whether on the XJ or E-Type were just disfiguring clutter and having them in silver & gold and with the feline sometimes at a different angle seems a minor but needless complication to the production process.

Still under the control of the doomed British Leyland, Jaguar lacked the resources fully to develop the XJC (1975-1998) and although it was displayed to much acclaim in 1973, not for another two seasons would it appear in showrooms, the programme starved of capital because greater priority was afforded to the XJ-S (1975-1996 and from 1991 officially “XJS”, a change most of the world informally had long adopted) which was thought a product with greater potential in the vital US market.  The XJC thus debuted with problems including (1) flawed sealing of the side windows which resulted in intrusive wind-noise, (2) a tendency of the doors to droop because, although longer and thus heavier than those of the four-door saloons, the same hinges were used and (3) the pillarless (ie a two-door hardtop) construction induced a slight flexing in the roof’s metal and while not a structural issue, because regulators had (quite sensibly) had lead removed from paint, the paint on the roof was prone to crazing.  The solutions (the development of exotic paint additives or re-designing the roof with heavier-gauge metal) would have been expensive and time-consuming so, in the British Leyland tradition, the Q&D (quick & dirty) approach was preferred and a vinyl roof was glued on but modern paints mean the ugly vinyl can now be removed so the roof’s lovely lines can be admired.  There are those who claim the “crazing paint” tale is just an urban myth and the awful stuff was glued on as a deliberate aesthetic choice because the look was then inexplicably popular (one of many lapses of good taste in the 1970s) but it's well-documented history.

Jaguar’s cancelled Growler (left) and the new (EV-friendly) Leaper.  According to the MBAs, the message the Leaper conveys is: “Always leaping forward, it is a representation of excellence and hallmark of the brand.”

The companion bad to the Leaper was the “Growler” which featured the head of a Jaguar, mid-growl.  There were over the years many version of the Growler and it appeared variously on trunk-lids, grills, steering wheel bosses and such.  Because as a fitting it was never rendered in a way likely to cause injury to pedestrians, it might have been supposed it wouldn’t be vulnerable to cancellation but it transpired the Growler poses a significant moral hazard, presumably on the basis that while the somehow sensuously feminine Leaper is acceptable, the Growler embodies toxic masculinity.  Whether Jaguar’s MBAs discovered this from focus groups or divined it from their own moral superiority hasn’t be revealed but in 2024 the company announced the Growler would not re-appear when the new range was launched in 2025.  Given the public response to the DEI (diversity, equity & inclusion) themed preview of the company's EV (electric vehicle) re-brand, the presence or not of the Growler may not be of great significance but a new expression of the Leaper, (with something of a stylistic debt to the IBM logo), would be included so there’s that.

1985 Jaguar XJ-SC with after-market large Leaper.  Because of regulations, US the market XJ-S used quad circular headlights rather than the twin oval units otherwise fitted and while many don't like them, the "four eyes" look was closer to Jaguar's traditions.

Leapers have been fitted to some XJ-S and XJSs where they really don’t belong, the factory never installing one.  If it’s done, the least-worse approach is to use the small Leaper from the Mark X/420G and remove the Growler badge (if fitted) while the WCS (worst case scenario) is to leave Growler in place and add a large Leaper which really is too much clutter; with pre-modern Jaguars, less usually is more.  Still, for those who insist, reproductions of the classic 4¾ inch (120 mm) feline predator are available and those manufactured by German Jaguar tuner Jochen Arden comply with the EU’s rigorous safety regulations in that maximum pedestrian impact protection is afforded by the design integrating both lateral and horizontal rotation of the assembly.  The part is supplied as a kit which includes adapter plates to suit a number of otherwise leaperless jags and, being German-made, there is of course a “lifetime corrosion warranty”, the small print limited to (1) rusty Leapers purchased after November 2011, (2) not damaged and (3) validity restricted to the original purchaser and presentation of the original invoice.

1988 Jaguar XJ-S V12 Convertible by Hess & Eisenhardt (left) and 1989 Jaguar XJ-S V12 Convertible (right).  Note the bulkier soft-top used by the factory, necessitated by retention of the coupé's fuel tank.  The after-market, anodized plastic fittings on the wheel arches are, on an XJ-S, as undesirable as a Leaper.

When introduced in 1975, the XJ-S was available only as a coupé, the prevailing feeling in industry it was only a matter of time until US regulators outlawed convertibles.  For a number of reasons, the ban was never imposed and by the 1980s toes were again being dipped in the topless market, Jaguar in 1982 releasing the XJ-SC which featured a targa-like structure somewhere between that used on the Triumph Stag (1970-1977) and the various landaulets with “fold-back” roofs.  It was thus not a true “convertible” and sales were disappointing, demand limited further by the thing being purely a two-seater, the rear compartment re-configured as a generously-sized storage apace.  The dealer-feedback (notably from the US) however indicated there would be demand for a convertible XJ-S, something confirmed by US specialists Hess & Eisenhardt selling some 2000 of the conversions fabricated between 1986-1988.  Accordingly, in 1988 the factory released an XJ-S convertible and although also a two-seater, it proved a great success.  Interestingly, the factory’s design almost replicated the approach earlier taken by Jochem Arden with most of the coupe’s components retained.  This did necessitate the soft-top not folding especially low, unlike the Hess & Eisenhardt cars although to achieve that, modifications were made to the fuel tank and among some that proved controversial.

1968 Mercury Cougar GT-E 428 in Augusta Green Poly (left) and 1968 Mercury Cougar GT-E 427 in Grecian Gold (right).  Other than the Jaguaresque iconography, about the only thing European about the Cougar was the use of the French spelling of “litre”.  Ford in 1966-1967 also used a “7 Litre” badge, for a model which was fitted variously with the 427 & 428 cubic inch (7.0 litre) FE V8s.  The interchangeable badges were probably not a cost-saving measure but may have been to avoid the complaints Shelby American received as a consequence of fitting both the 427 and the less robust 428 to AC Shelby Cobras universally badged as “427”.

1968 Mercury Cougar GT-E 427 in Grecian Gold (left side badge).

Ford's Mercury division also had a stylized feline, introduced in 1967 when the Cougar debuted.  Unlike Jaguar's symbol, the cougar wasn't leaping but was caught more in mid-prowl although Mercury's marketing department would probably have liked people to have thought of it like that; the Cougar was that sort of car.  Although in colloquial use, cougars are often referred to as “big cats”, in zoological taxonomy, felinologists restrict the “big cat” classification to the genus Panthera (lions, tigers, leopards, snow leopards & jaguars) and one defining feature of the Panthera cats is their ability to roar, made possible by a specific adaptation in the larynx and hyoid bone.  Lacking the anatomical feature, like cheetahs, cougars are not able to roar.  Often known as the mountain lion, puma, or Puma concolor, despite their size, the cougar is more closely related to smaller cats so it’s properly a “large” cat rather than a “big cat”.
