So you know I've been wanting to ask this question for some time now.
Everytime you hear about an aviation disaster it is usually a plane that has had some trouble either with technical stuff or less often due to pilot error or otherwise, but what I want to say with that is that a big commercial jetliner never falls out of the sky like a rock but usually loses altitude gradually over some period of time after everything fails like in the worst scenarios where all engines fail and maybe even the system that control the aircraft's flying position.
Now surely there are sometimes moments like terrorist attacks or a plane being shot down by a missile like the recent Malaysian jet over Ukraine using the Russian Buk surface to air missile, in those situation my idea would not work because the plane and its fuselage is damaged and blow to pieces and it then falls almost like a rock in free fall.
So the idea is this, in normal technical problem situations where the plane descends as it loses power or maneuverability, why can't we equip every passenger with a parachute that has also special vest built in so that the person wearing it could float above water and not sink, as many flights cross oceans and large volumes of water where in the case of the plane falling help is far away.
So the question that rose to my mind while watching plane documentaries and disaster ones is this. Now at the cruising altitude of modern jetliners it would be impossible to open the doors due to the difference in air pressure and lack of oxygen but as the plane descends to lower altitude , something like 3/4 km it becomes perfectly fine to open the doors and the passengers could just jump for their lives.
Now normally when a plane falls there are almost never any survivors because the speed of impact is so large than both the plane and the people within get killed instantly so I think that jumping while the plane is still descending would have 90% or so higher chances of surviving.
What do you think why hasn't this been done given how relatively simply it is and inexpensive?
