Folding Luggage Trolley

In a plane crash nearly everyone dies so: The airliners were stripped to provide a pair of doors of the cabin which can be folded flat so that the carriages and passengers can walk through, which can be opened emergency. There will be stairs leading to a separation between small luggage, which is illuminated and is stocked with a parachute for each passenger. (They will be informed in advance before the flight) They all have the strap in a suit parachute and heat, like a combination in which the body can survive extreme cold. The driver then slows down, when passengers are ready, at an altitude where the costumes are really adequate heat, and the speed is understandable for a jump. The passengers then exit through the static line or free fall (depending on time and / or aircraft) on a door built into the lower fuselage, next to the opening of the landing gear (in not weaken the fuselage to a large extent) and output with built in life jacket for landing in the water.

Are THEY?

For God's sake, if the aircraft is in good enough condition to allow all that, then the plane is safe to land. Even with a briefing you kill more people under a parachute to save. You must get training on systems. Skip plane is not all easy to do for the first time either. I am an active skydiver and I'll be gone in a heartbeat, but I figure I need at least five minutes to get on my rig and exit. More time for the doors and all that jazz.

It's still not going to happen. Have you been on a flight lately? take a 737, only 120 passengers or more and it takes 15 minutes to get everyone in the plane when it is parked at the door.

The only way I could see your idea is worth it to be is whether the landing gear was stuck and could not be released. In this case, it would be a great idea for people trained in parachute, not an information session on exit, but everyone has a better chance in landing the aircraft with the gear retracted.

Moreover, even with my parachute training. I do not have the skills to use supplemental oxygen. So the plane should be controllable enough to get below 17000 or 18000 feet MSL to make this plausible. Again, if the airplane is controllable enough to fly slow, and low level long enough for hundreds to put on parachutes and exit the plane is in pretty good shape to land.

Moreover, the vast majority of accidents occur during takeoff or landing, where a parachute is useless. there is not enough altitude or time to use a parachute.

There is not enough room to put on a parachute in a commercial aircraft. Everyone would have to wear the platforms before boarding the plane. Even if everyone had a parachute, there is no safe way out of the plane. You would need special equipment and training to survive the winds 560 + mph and an altitude over 30,000 feet. Without oxygen and protective gear you would die in that environment. The fastest skydiving jumps are at 150 knots, not 500 + knots and are made from 18,000 feet MSL or lower. Just out of the plane could kill you as you would be struck at the exit door. The next question would be landing a parachute. Most likely this case would use rounds and you just have to make a drop landing. It's pretty easy to learn. The direction of the canopy would require training. I'd say about 25% of the population on all flights are not healthy enough to survive a normal jump. Very young, old, and anyone not in good health would have no chance of surviving the exit, parachute flight or landing.

As a skydiver, we know that at some point we will exit our aircraft during an aircraft emergency, it does not happen very often, almost never, but it does. But here's the catch, it takes time and altitude to open the parachute. We wear seat belts in it.
