If an airliner looses it's air supply in flight (decompression) and crashes as we read about last week and all of the people were found EXCEPT the pilot I wonder what actually happened. What if the pilot wanted to crash the aircraft,for some reason, and had a plan to do it as follows: (1) Hide a parachute onboard the plane,(2) hide a supply of oxygen onboard,with mask(3)Sabotage the aircraft's main oxygen supply. If this "James Bond movie-like scenario was actually carried out could a man exit the plane in flight or would the air pressure keep the door of this jet sealed?(Some jet aircraft can be parachuted from while in flight as this appeared to happen several years ago with that guy whose name escapes me now.)What do you pilots think?
