Without disrespecting victims (RIP), can someone briefly explain how and why people die during plane crash? Is it lack of oxygen, or cold temperature or actually a hard landing on the water surface? AFAIK most studies conclude there is no good place on the plane to be safer than other, whether its front, back, left side or right. Any ideas how to expand ones survival chances? Will TSA let you in with parachute -- is it even worth carrying one??
That would mean an opening if there's an opening in the plane, while still above the ground, the plane is done anyway.
I think it's the fire or suffocation (the plane is sealed) if it falls in the water. I really don't know. Go over to reddit, there people there are better chances of an answer.
