I like to think I know as much about aircraft as possible, but only as a passenger. I have flown on many types from small Cherokee´s through Islanders, Caravelles, Mercures, Viscounts, DC3´s and most of the Boeing and Airbus types. Even 2 Boeing 757´s can have different set-ups onboard.
I watch every demo and look for my exit route. I am afraid that anyone sat between me and that exit that doesn´t watch the demo is mine for the taking. While they sit and wonder I will be scrambling over them, no intention of helping them. They should have helped themselves by watching the demo.
Sorry if this sounds harsh.
