I saw this video yesterday and was like holy shit, that's possible? Apparently some guy in the Air Force a few decades ago skydived from more than 100,000 feet (you can fuckin see space, as you see in the video) to prove it was feasible for pilots of high-flying jets.
this would be amazing. I want to do it.
Holy shit that takes balls to do doodhuh;
I'd have a heart attack long before reaching that height and there is no way in hell i'd jump

it is honestly one of the most enjoyable and orgasmic things I can imagine
Wow, I didn't even know jets could go that high.
That actually is pretty damn awesome. I'd love to do that some day.

I don't know if ejaculation is a good idea when you're accellerating at 9.8 m/s^2
Holy shit he's almost in space...
I want to skydive one day. Maybe not from that height, but I want to.
That's gotta be the most exciting thing anyone could ever possibly hope to do....holy fuck
I WANT TO DO THIS.

yes you can see the fucking curvature of the planet and shit and free fall for like 5 minutes

It is a balloon, not an jet.

This.
You can see the curviture of the earth from 60,000 feet, as was evident with the Concorde.
Am I the only one who's seen this video many times before? Great song, my favorite from Boards of Canada.
But yeah, pretty incredible, dunno about myself doing it though because I'm pretty sure I'd puss out.

No suspect music added for effect on that one.

And even at that altitude it gets dark as a nigger.

"...the ascent took one hour and 31 minutes..." or roughly 1,130 feet per minute, not bad at all, comparable to some low performance WWII aircraft
Depending on the strength of the balloon, you can raise the air to a pretty intense temperature. Force bouyant is pretty impressive, even in air. It would slow down while the air thins, though.

yes but it would be 40% cooler from 100,000 feet

60000(1.40) = 84000.
You mean about 67% cooler.

this is why math is wrong and I am right

i was going to ask how far (and for what duration) one could glide from the point of departure at that height with those winged free fall suits on

it's a difficult calculation due to changing air density, thus a changing C constant...I think that's a double integral calculation, and then you have to find the new air resistance after the parachute deploying, and the force upwards which will reduce the landing speed at h=0 to...nothing faster than 30 mph, preferably.

what about the earths rotation, jet streams etc... akudood;

We're assuming that the corliolis effect doesn't effect elevation of landing, since you'd probably land in the ocean any.
Also the wind may or may not be a significant factor, I didn't think of it. But compared to falling from 100k ft in the air, I don't think it's a factor. But air resistance functions on a F = Cv^2 (usually) equation, so it's pretty significant.
so basically we have to jump from a balloon at 100k with a cool suit to find out

I'll do it and let you know
the guy landed in new mexico, not the ocean, since swimming with a pressure suit and helmet and a bunch of equipment would probably be a minor inconvenience

Unless you know you had flotation devices which would be inexpensive and light but whatever

...or you could just parachute onto the desert and not risk drowning, and at the very least, not get wet. seems like an easy call

The Cessna I used to fly climbed at 500 fpm on a good day and if we really wanted our ears to pop we would climb at 700 so that's pretty damn good

statistically a very low probability, in such cases most problems arise as a result of human error, not design flaw
chutes are packed by hand, by specialists, and checked, re-checked, very unlikely such an individual would make a mistake twice and have no one notice it

i don't think a grown man has enough punch at terminal velocity to make much of a crater, probably just a big mess

That would cost so much money, if they released this kind of activity to the public.

if you have the money, resources, and expertise, there is nothing to stop you, no one own space (officially) or this kind of activity

yeah I was going to say this. it's not like if you actually did the necessary training and bought/prepared all the equipment, someone could stop you.
