200 self inflating parachutes shoot out ahead of the plane slowing it down, catching most of the energy and creating a mesh around the stricken airplane bringing it safely to ground.
Yes ahead of the plane, slowing it down as the plane passes through this "mesh" of parachutes.-- pashute, Jul 21 2014 Parachutes for small planes already exist http://www.wired.co...quits-over-bahamas/Per an annotation, we simply need something appropriately larger, as the final parachute for a large commercial airliner.

The final chute could be deployed from the top of the aircraft (see link), and be very large.-- Vernon, Jul 21 2014 // very large //
Ballistic recovery parachute for a civil airliner ?
So, you're 7000m AMSL travelling at 600 knots, and it All Goes Horribly Wrong. The object is to bring the airframe to the ground with a maximum vertical speed of about 5 m/s, and a similar horizontal speed, for an all-up mass of around 200,000 kg.
There are tables that tell you how big parachutes need to be for a given jump weight ...-- 8th of 7, Jul 22 2014 That's why there are 200 small chutes, [bigs]-- pocmloc, Jul 22 2014 each chute goes out separately adding up the effect. I saw that link before, and was solving for a large aircraft.-- pashute, Jul 22 2014 Never understood why all passengers can't pile into a single capsule with its own chute, and jettison the rest of the plane.-- 2 fries shy of a happy meal, Jul 22 2014 I always wondered that intentionally braking down pieces off the plane (much like F1 cars are designed to "loose" their mass while crashing) when In Big Trouble would help. I mean you can throw away large mass items like engines, wings, APU, cargo and so on.
The passenger area would be made a "cage" fitted with a nicely sized parachute.
Surely not a safe ride home (down down down there), but survival rate would be higher.
It would be a hell of a challenge for the engineers to create such a design.-- create, Jul 22 2014 or have an airplane within an airplane.
but that's not this idea...-- pashute, Jul 27 2014 random, halfbakery
