I was flying from LA to Sydney a few years ago and 2001: A Space Odyssey was available on the entertainment system. After a few hours and a couple of glasses of wine I put it on and fell straight asleep. I awoke groggily some time later to this[0] frame from the movie. The next second and a half I experienced pure terror until I realised I wasn't plunging to my death in the middle of the pacific ocean and how the pre-flight safety briefing really sugar coats the reality.
