How did the Hindenburg Crash?
920713
A spark of static electricity caught some leaking hydrogen on fire.  The skin of the ship was made of aluminum oxide which some solid rockets use for fuel today, so that burned pretty quickly and caught the rest of the ship on fire.  The static electricity is said to have been caused by some bad weather.

sky dive (something dangerous)

Because there is no air, yet at the same time they need to hit the air so they can get lift for a soft landing.  The problem is that the air that does exist at such high altitudes is so sparse that it doesn't have the density to provide the lift, so it ends up hitting the craft at a super fast speed which heats it up.  Eventually however, the air is dense enough to provide the lift that it needs.

I heard on a radio show (Coast-to-Coast AM) an amazing and incredible replay of a man in 1970's Los Angeles (via CB radio) who actually became airborne in a chaise lounge with 100 large helium-filled balloons.  It is simply riveting to listen to the recorded account in which his voyage was suddenly jump-started due to the unexpected power of lift from the balloons in which his chaise lounge (anchored to a jeep) was torn away.  He soared to 24,000 feet!  A pilot of a major airline passing by was in shock and had to report to the tower the flying chaise lounge!  It was hysterical!  The man was an engineer, I believe at one of the local aerospace companies.  He maintained CB radio contact with his girlfriend on the ground, who was totally frantic and freaked out.  He took with him a be-be-gun to shoot each balloon gradually to lower his altitude.  Eventually, he brought the chaise lounge back down to the area of Glendale, and he crash landed in a residential backyard right next to another man--- laying on his chaise lounge.  It was unbelievable, and a riot!

Yes this happens and it happens because when an airplane lands it displaces air around it with a high pressure and speed.This large volume of displaced air with high speed exerts a high pressure on the car and it flies away from the track

I don't think it's a picture of the actual plane that later crashed, but a still/publicity photo of the band on another plane.  \n\nThe one from the crash, was a chartered Convair 240 carrying the band between shows from Greenville, South Carolina to LSU in Baton Rouge, Louisiana and it crashed near a forest in McComb, Mississippi.

He accidentally killed himself.  He was an inexperienced pilot and while piloting a plane with his wife and sister-in-law on board, he crashed.  The crash resulted in the death of all.  It was a hazy night and he crashed into the Atlantic ocean.

The following assumes the plane is in the air and high enough to kill you!\n\nAfter around 10 seconds (c1000ft) you will be falling at c120mph - although there are a handfull of cases of people surviving what are reported as 'free-fall' landings, they are usually under partial failures of a canopy or a main/reserve wrap.\n\nI watched a girl 'go in' under a main/reserve wrap - I would reckon she was doing c30mph when she hit ... way off the 120mph you would do with nothing.  Fortunately she survived.  Imagine a car hitting you at 120mph!\n\nI suspect that the tandem incident in an answer above is either an urban myth or involved a partial malfunction - even if the jumpers landed on their backs (required for instructor to be underneath) the deceleration trauma would be fatal at the nearly 200mph a tandem reaches (faster due to twice the weight and the same surface area - physicist please do not flame me I am right ... this is why tandems deploy a drogue chute long before the main).\n\nIt is pretty likely someone will suggest aiming for water - this DOES NOT work.  Hitting water is pretty much like hitting concrete due to waters inability to get out of the way at these sort of speeds.\n\nBottom line, unless you get rescued in mid-air by other jumpers jumping with you (has happened a few times!) or, as you suggest, jump without one, you have an almost nil chance of survival.\n\nThe best advice if you jump without one or have a double failure is to tie your shoelaces together - it wont help but it will take your mind off the problem!\n\nBlue skies, black death =8-)\n\n\nDrop me a note if you need any more information\n\n\nADDITIONAL - response to other answers (good debate folks)\n\nWith regard to an answer above I have also heard or hitting trees etc as helping but only where the speed was already low due to a partial malfunction - documented case of a guy surviving by falling through the roof of a convent and another into very deep snow.  Ditto on the 'relaxed' posture.\n\nOpening you chute 'a couple' of seconds before impact is probably an exaggeration as it needs (say) 4 to deploy fully (reserve maybe 3) - as soon as deployment starts you will decellerate massively but you need it open for it to be borderline 'safe'.  BTW if you pull low on a drop zone and survive you are unlikelly to be jumping there again!\n\nWith regard to the chair idea ... em not unless you are a cartoon character :-)

Because it couldnt fly

there are multiple possibilities.\n\n*  fire/suffocation - perhaps the plane's engines caught fire or the internal pressure was lost causing decompression and oxygen loss.  death would have been either extremely painful (fire) or relatively painless (lack of oxygen)\n\n*  impact trauma - perhaps they lived through the descent, only to suffer massive body trauma upon impact.  though the plane's structure would have absorbed the bulk of the blow, the sudden deceleration of impact would have caused their bodies to slam into the seatbelts/restraints, causing severe internal damage.  airline safety procedures for impact assume a controlled skid landing - this would have been the equivalent of dropping a large rock into a pond.  extremely painful and not too quick.  of course, that doesn't matter because of the next point.\n\n*  drowning - the impact would have burst open the frame like a tin can, letting water enter the cabin.  death by drowning is not terribly pleasant as far as I understand it.

There seems to be a part missing.\n\nPossibly airplane:Wright::telephone:Bell

The infrastructure to deliver teh hydrogen isn't set up yet.  But the biggest problem is where do you get the hydrogen?  It's not like you can sink a hydrogen well.  You need to liberate it from some other molecule like water and that takes a lot of energy.  Right now the cheapest form of energy is fossil fuel so we would just burn oil to liberate the hydrogen.  \nIt is also a problem to transport.  Needs to be highly compressed or it takes up a lot of space.  That takes more energy.  It is a bit dangerous to carry a compressed gas around.  The tank could rupture but don't worry about H-bomb issues.  Fusion isn't easy to do.  And the Hindenburg was more of a problem with the skin of the blimp.  As far as explosion I would rather be in a car accident with hydrogen then gas.  Once the collision is over the hydrogen will float up and away.  The gas will pool around all the hot engine parts and electric sparks and will be more likely to catch afire and burn you.\n\nThe up side of hydrogen is that it can be reacted in a fuel cell.  This is much more efficient then an internal combustion engine.

it's a plane that goes into a steep dive.  the folks in the fuselage section are not strapped in and experience weightlessness during freefall

Give it up!  What new questions?  Airplanes crashed into building!!  People were killed, not just Americans.

it is a very controversial issue ,many says he died in plane crash  but i personally does not believe in this\n\nyou have to wait for the exact reason my dear

It was a plane!!! The passengers died and the plane is disintegrated. Look at flight 97...the one that crashed in the field...tell me...where is the plane and passengers...at that speed and height nothing is left for viewing...its all disintegrated. Or perhaps you can explain to the families that lost love ones that it was some secret missile.

Remember, momentum is affected by mass.  The fly's mass makes it easier to dissipate the inertia.  So it seems that the fly could crash into the front, but not likely. Of course, most people are worrying about other things at the time, so no specific measurements have been taken!  The air inside has mass also, so in effect the car and the air mass have become one unit, in which the fly is also a small part.  When it stops, it helps everything else stop.
