Highest altitude jump

Surfing and found this. Its decades old, but still an amazing achievement.

Captain Kittinger was assigned to the Aerospace Medical Research Laboratories at Wright-Patterson AFB in Dayton, Ohio. For Project Excelsior (meaning "ever upward", a name given to the project by Colonel Stapp), as part of research into high altitude bailout, he made a series of three parachute jumps wearing a pressurized suit, from a helium balloon with an open gondola.

The first, from 76,400 feet (23,287 m) in November, 1959 was a near tragedy when an equipment malfunction caused him to lose consciousness, but the automatic parachute saved him (he went into a flat spin at a rotational velocity of 120 rpm; the G factor at his extremities was calculated to be over 22 times that of gravity, setting another record). Three weeks later he jumped again from 74,700 feet (22,769 m). For that return jump Kittinger was awarded the Leo Stevens parachute medal.

On August 16, 1960 he made the final jump from the Excelsior III at 102,800 feet (31,330 m). Towing a small drogue chute for stabilization, he fell for 4 minutes and 36 seconds reaching a maximum speed of 614 mph before opening his parachute at 18,000 feet (5,500 m). Pressurization for his right glove malfunctioned during the ascent, causing his hand to swell. He set records for highest balloon ascent, highest parachute jump, longest drogue-fall and fastest speed by a man through the atmosphere.

The jumps were made in a "rocking-chair" position, descending on his back, rather than the usual delta familiar to skydivers, because he was wearing a 60-lb "kit" on his behind and his pressure suit naturally formed that shape when inflated, a shape appropriate for sitting in an airplane cockpit.

For the series of jumps, Kittinger was decorated with an oak leaf cluster to his D.F.C. and awarded the Harmon Trophy by President Dwight Eisenhower.

I would love to do that. Edge of space stuff. Awesome.

Impressive stuff, it is hard to comprehend falling 19 miles.

Relative sizes of all earth's water v earth's atmosphere

This a model that shows the Earth (diameter 12,756 km) with the next largest sphere being all the Earth’s atmosphere rolled up into a ball (diameter 1999 km and 5140 trillion tons) and the smaller sphere is all the Earth’s water, sloshed up into a ball (diameter 1390 km and 1,4087 billion cubic kilometres). Despite the numbers, visually there’s a lot less than you might think.

And the really tiny sphere (diameter 62km), to the left, hat’s all the Earth’s fresh (drinkable) water.

I'd say NOTHING would ever give you the same buzz.

Depends if you like falling tbh.. Lots of ppl have nightmares where they keep falling and wakes up just before they hit the ground!

Altho I don't think it was an accident he jumped out of the airplane :D

maximum speed of 614 mph

thought the speed of a fall was set and not able to be any faster then what the gravity pull is unless you add a power source that increase the speed

Not correct. At that altitude the air is almost pure. No air resistance, so its perfectly possible to accelerate freefall to 614 mph. Thats also why he doesn't burn up. There's no resistance or impurities.

or, that fact there is no air at that altitude

Very little air resistance to put the brakes. Same reason he starts spinning like a top. If he'd ejected funny, wonder what rpm he could've ended up spinning at or if it'd end up fatal.

Suprised velocity not faster tbh, iirc top speed on normal skydives is 120-200mph? Guess already starting to hit atmosphere just as accelerating to a decent speed. He doesn't really want to come in like a meteorite at 20miles per sec either.

I'd guess it be hard to time... and have the parachute work at 20 miles/sec

i like the fact it was an unprecedented, dangerous experiment

and they got a ginger to do it!

why not use a ginger?

make the loss as little as possible in a experiment if it would go wrong

Hey maybe this could be a new and exciting FH poll

Who would you throw out of a helium balloon 20 miles up ? With no parachute.

so is 200ft but its not as epic, im voting terry wogan, 1) to see if radio2 would then go off the air, and 2) because im sure it would be fairly amusing voice recordage

dont be silly!
no one would watch eurovision if it wasnt for the woganator!

Why on Earth didn't I see this thread when it was made? Also can you tell I'm bored, this was on page 504.

I've wanted to do a H.A.L.O drop for years and then I read and article about this and was like "Fuck yeah!" First person to ever go faster than the speed of sound without a means of propulsion as well iirc.
