Only true aviation geeks are likely to celebrate, or even notice, the milestone being celebrated this year in the history of aviation: the debut, a century ago, of the autopilot. In June 1914, at a historic aeronautical-safety competition in Paris, a 21-year-old American daredevil pilot-inventor named Lawrence Burst Sperry stunned the aviation world by using the instrument to keep a biplane flying straight and level along the Seine. According to his biographer, William Wyatt Davenport, Sperry stood on a wing as the plane, in effect, flew itself—a feat that won him the event’s $10,000 prize.
By eliminating the need for taxing “hand flying” on long journeys, and thereby reducing pilot fatigue, Sperry’s autopilot ultimately made flying much safer. But it had another, less obvious benefit. It freed up pilots to do other things with their hands—and bodies. The brilliant young Sperry himself soon grasped the possibilities. Legend has it that in late November 1916, while piloting a Curtiss Flying Boat C‑2 some 500 feet above the coast of Long Island, he used his instrument to administer a novel kind of flying lesson to one Cynthia Polk (whose husband was driving an ambulance in war-torn France). During their airborne antics, however, the two unwittingly managed to bump and disengage the autopilot, sending their plane into Great South Bay, where they were rescued, both stark naked, by duck hunters. A gallant Sperry explained that the force of the crash had stripped both fliers of all their clothing, but that didn’t stop a skeptical New York tabloid from running the famous headline “Aerial Petting Ends in Wetting.” For his caper, Sperry is generally considered the founder of the Mile High Club, a cohort that loosely includes all those who have ever “done it” in flight (though precisely what constitutes “it” remains a lurking definitional issue).
“Flying,” the 1930s stunt pilot Pancho Barnes is often quoted as saying, “makes me feel like a sex maniac in a whorehouse with a stack of $20 bills.” Today’s overcrowded, underfed, overstressed airline passengers, consigned to travel in “just a bloody bus with wings” as Ryanair CEO Michael O’Leary puts it, are unlikely to share that enthusiasm. It’s all the more remarkable, then, that airborne sex remains on the bucket list of plenty of passengers, at least male ones. A “Sex Census” published in 2011 by the condom maker Trojan found that 33 percent of American men aspire to have sex on an airplane. (The top locale for women: a beach.) Similarly, nearly a third of the Brits who responded to a 2010 TripAdvisor poll said they wanted to try in-flight sex.
A lot of U.S. fliers may have already acted out that fantasy. In a global survey of more than 300,000 adults conducted in 2005 by the condom maker Durex, 2 percent of respondents worldwide (and 4 percent of American respondents) claimed to have had sex on an airplane. A 2010 survey commissioned by Sensis Condoms (when did condom makers become avid pollsters?) found a similar incidence of in-flight sex (3 percent) among its respondents. Assuming that about 100 million Americans have traveled by air, and discounting for lying braggarts, if even only 1 percent of them have indulged, then that’s a million or so Mile Highers.
Less-than-scientific anecdotes abound too. When Virgin Atlantic installed diaper-changing tables aboard its new Airbus A340-600 long-haul jets, in 2002, it wasn’t just mothers and children who found them useful. Within weeks, according to the airline, the tables were destroyed by “those determined to join the Mile High Club.” That said, the airline’s founder, the billionaire bad boy Sir Richard Branson, has waxed nostalgic about a tryst he had at age 19 in a Laker Airways lavatory (“It was every man’s dream”). Almost 20 years ago, Singapore Airlines, for its part, reported that a third of its cases of “unruly behavior” involved in-flight sex.
For the airlines, the “sexy skies” are all about marketing the fantasy. Actual in-flight sex is the last thing they want to deal with, especially since 9/11, when the preferred cabin ambience has become no-fun, no-drama—a shift more self-protective than puritanical. Is it just love, or is that couple huddled together in their seats trying to ignite explosive-filled sneakers? Even a visit to the bathroom can trigger a full-bore fighter-jet scramble, as it did on the 10th anniversary of 9/11, when a pair of F‑16s shadowed a Frontier flight until it landed in Detroit after two passengers made for the lavatory at the same time. Cabin crews working chock-full flights now also have no time, much less the inclination, to play chaperone.
