After three? four? hours, my legs have fallen asleep, and I'll need to deal with the inevitable discomfort of waking them up again. Sleep is impossible: the seats offer no neck support, the bulkhead is hard and not built for sleeping on; trying to lie on the tray table causes my intestines to tie themselves into gas filled knots.

Well, the FAA is being ignored then. I just can't see that happening.
- will_hughes 9y agoI suspect the testing is only being done on a planeload of people who've just recently sat down. Keep them in their seats for 3 hours, knees jammed into the backs of seats, passengers with laptops and blankets and slippers, some of them asleep - and then see if you can evacuate a plane in 90 seconds.
