how many people have been saved by life belts?|||Parachutes are not for untrained people and jumping from an airliner is just not a thing that people can do--the first thing you would do is hit the tail section--a fatal mistake. And you cannot breathe at jet speed or at high elevations--so you are dead anyway !! There are life belts because firmly belted into a seat is the very best safeguard when a plane hits turbulance or it does have a surviveable wreck. Just like in a car--you keep going the speed at impact--your body can fly around at 100 or so mph---you can kill people by colliding with others in the plane. Not to mention hitting the interior sections at 100 or so mph. People in cars without using seatbelts are often ejected at highway speed or partially ejected--only to be cut in half by a rollover or being dragged half out of the car--an ugly sight for the family survivors who have to bury you.|||You cannot jump out of a commercial airline. A life jacket may be handy if you crash in water.|||I don't have any experience with this or anything, but you would think that it would be pretty pointless to give a parachute to someone who doesn't know how to use it. You open the parachute wrong and you might as well not have it.|||There is not enough oxygen at the heights traveled by commercial airlines. It is not practical to store the number of chutes needed for all passengers and crew. There is also the time needed for everyone to chute up. It just isn't practical.|||I agree with everyone else above , plus the fact that if you parachute over the ocean, the shute will probably drag you down under anyways, with or without a life belt/jacket on|||Everyone surviving the crash of an aircraft, in recent memory, have had their lives saved by seat belts.
Having made a few crushers of my own on landing a Cessna, I would have wound up in the baggage bay behind me if I hadn't been strapped in. Having been standing in the cockpit entry to take notes on the maintenance flight of a Hawker I'd repaired, I nearly went through the windscreen when the ex-navy pilot drove the old bird into the ground like he was trying to catch a wire on a carrier.
I recall a time when as soon as the light was off, everyone took their seatbelts off. Now, they ask you to keep them fastened at any time when you're in your seat.
An airliner, that you know is going to crash, is going to crash somewhere. You might not know where, but somewhere.
So, is it safer to have a bunch of uninitiated people, families with children, senior citizens, panic and try to put on parachutes in the confines of an airliner, (think of trying to dress in your locker,) and let the airplane fly uncontrolled into a neighborhood, business center, skyscraper,... Or is it safer to have everyone buckle up and have the pilots try to fly the airliner to a safe landing in spite of the problems?
For one thing, airliners aren't safe to deploy from in flight. I don't care what any fictional writer or screenplay writer has written. It can be done on some aircraft, but it's not something you want the uninitiated public trying.
The center of gravity shift, (if you could get everyone into parachutes,) of everyone trying to go out the only door that won't put them into the engines, wings, or horizontal stabilizer, (resulting in a particularly gruesome death,) is likely to render the airplane uncontrollable, causing a stall and higher death toll when it falls out of the air because 90 people are jammed in one doorway, without their seatbelts, when the aircraft smacks into the ground.
So, unless you're willing for the airlines to charge the general public for skydiving lessons, aircraft familliarity lessons, have people dying when they drop onto a lake, a freeway, or forests, while an aircraft that might safely be landed plows into a neighborhood, 80% of the people on board because they were all jammed at the one exit they could get out of safely, fasten your seatbelt when the sign is illuminated.
JT|||In a commercial operation everyones best chance of survival is to stay with the plane, strapped into your seat until the aircraft has stopped.|||You are more likely to survive the plane crash as opposed to trying to jump out of and aircraft as you most like would die trying to get out of the aircraft, that and the added weight of all of those parachutes takes away from the useful weight the air craft could carry.|||Even if they had parachutes and you could jump out of the plane without training you would be dead probably before you even hit the ground.|||Military aircraft do have parachutes. It would be a nightmare to require large commercial planes to get people fitted into parachutes, rarely has there been an in flight problem where the pilot can say the following..passengers remain calm, put on your parachute and in single file to to the back door and jump out, this is a recording we bailed about 5 minutes ago!|||The seat belts are NOT there to save your life in a crash. Older aircraft are designed to a 9g limit, some fighter aircraft are capable of turning faster than that. Newer ones are designed to meet 16gs.
The seat belts are there to save you during turbulance and high energy braking.
You are assuming that an aircraft is escapable during a crash, it is not. It could be pitching and rolling on all axis, or diving for the ground, which would pin you to your seat anyway.
As the other people said, without the proper training, the chute would be useless. Additionally, skydivers leave airplanes that are moving around 130 MPH. Commercial aircraft move at closer to 500+ MPH. That speed would shred a 'chute if deployed. Also, you can't open an aircraft door assuming the fuselage is still pressurized. One more thing, an aircraft flies at 36,000 ft. cruising altitude. Bailing out at that altitude would deprive you of oxygen and you'd freeze to death in your mini-skirt (remember the hottie kicked off by SWA?). You'd be dead anyway, so what's the point of installing the chute?
Oh, one more thing, everyone already complains that there isn't enough overhead bin space. Where would you put it?|||All commercial aircraft flying in or from the U.S. must have
seats usable as floating devices when flying over water. The larger aircraft will not use parachutes as it is almost impossible for people to jump out in an emergency. If you survive a crash over water (most passengers do not) you might live long enough to get rescued if you have something to hold on to. You
wont find much use for a parachute if you can't get out of the plane.|||Oh man, goooooooooooood question.
