In February 2008, a video was leaked on the internet featuring a French air hostess performing a striptease for her pilot. Allegedly shot by other crew members on a flight to London, the video showed the saucy stewardess putting on a bit of a show in the cockpit.
Such hi-jinks among the crew are worrying enough when they're supposed to be concentrating on turbulence or "chicken or fish?", but at least most sky-high workers are discreet enough to be rarely caught. When passengers get the same idea, it's far more, er, in your face. A flight from Charlotte to Los Angeles last year was diverted to Albuquerque after a 50-year-old man removed all his clothes mid-flight and refused to put them back on again.
