Why Airplanes Don't Have Parachutes

Hey guys! Do you know that there are special, super-big parachutes... for airplanes? But even an airplane can have a parachute of its own, why don't they supply each passenger on the flight with a personal parachute?! Wouldn't it save hundreds of lives should a crash happen?
Apparently, the answer is "no, it wouldn't." But every commercial airliner has a life-jacket under each seat, so why not shove a little parachute in there as well? Now now, have some patience, because to answer this question, we'll have to talk about some parachuting basics.

SUMMARY:
- Only specially-trained and equipped skydivers jump from altitudes higher than 15,000 ft. Otherwise you risk a lack of oxygen which can lead to confusion at critical times.
- A typical sport parachute and harness weighs about 15 pounds and doesn't come cheap! All the equipment a skydiver needs to own can cost from $6,000 to $9,000!
- Obviously, it's impossible to fit a 4-hour skydiving course in a 10-minute-long pre-flight instruction.
- Experts claim that most people wouldn't even get as far as to get ahold of their chutes.
- On board a commercial airplane that’s going down, there would be about 200 panicking people. Do you think they would patiently wait for their turn to exit the plane?
- If each of 200 passengers on board had a 15-pound parachute of their own, it would add more than 3,000 extra pounds to the flight's weight.
- Moving along, using a parachute to save your life only makes sense if your plane goes down mid-flight.
- The plane would be moving too fast for the passengers to leave it without smacking the side of the aircraft.
- So far, the largest plane equipped with a parachute can carry 5 people at the most.
- Apparently, a parachute can save a small plane that fits several people, but experts aren't so sure about big commercial aircraft.
- For a large plane, it would have to be not one parachute, but a system of chutes.
- The idea of a detachable cabin was first suggested by Gleb Kotelnikov, a Russian inventor, in the 1920s.
- This more than 9-decade-old plan is our best hope to ever equip airplanes with parachutes. Not any time soon, but one day - definitely.
