negativeblue writes "Dropzone.com has (had) a story about the preparation of a man (Jeb Corliss) who prepares to land a wingsuit without a parachute. If you don't know the current abilities of parachutes, now-a-day, you should do your research. Basically airfoils, they can perform close to an airplane wing (high performance turns and lift)."
if you've ever seen a base jumping video 90% chance it was jeb.
Cool stuff, though. I won't be trying it.

...that this guy is more likely going to win a Darwin Award than survive his fall.
Oh well, I guess something's got to thin the herd...
There's a Mercedes gap too. I want one and can't afford one, but it's not government's job to do anything about it.
I sure hope he hasn't used wax and feathers as the material for his incredible man flying machine.
If you don't know the current abilities of parachutes, now-a-day, you should do your research.
Shouldn't that be wingsuits? I should dearly hope that most people know the abilities of parachutes - they have been a regular plot device in the media for years.
why most famous BASE jumpers are dead. This is it. Unless he's got some secret technology nobody knows about, this is likely suicide. It's also not good for the public image of skydiving when sombody dies like this.
I'm no expert in aerodynamics or atmospheric dynamics, but don't you take a huge risk with that (apart from the obvious things) with the help of a nasty gust, updraft or the like, an un recoverable spin could occur.... The problem with having a set of wings and no engine is once you our out of control, recovery won't be easy.
So we are gonna have Batman soon.. Position of Robin is probably available. Any takers ?
... and I shall strike upon thee with great vegeance, furious anger and a slightly positive karma.
I'm sure these guys know what they're doing and are figuring out the equations, but here's a suggestion I would like to make: try landing in the suit near the edge of a big cliff, like perhaps near the Grand Canyon, for example. If Jeb gets very low and doesn't like his chances, he could try his damndest to pull up and clear the cliff edge, giving him another chance to release his parachute.
On the other hand, if he did pass the point of no return and went for the landing and overshot a bit, that might be a problem. hmmm.
Water - try landing on water first. Or a mattress - king-size, preferably.
RTFM; please, I beg you.
...from the Addams Family. Every time he did a jump, he used a smaller parachute. By his theory, eventually he would not need any paracute at all.
And of course, he was correct. Eventually, he would have no need for a paracute...
That's falling... with STYLE!
Way cool... nice photos in TFA.

Not strictly true - the following is one of several true stories of WW2 bomber crew jumping without chutes and surviving.. in this case because he landed on a glass-roofed railwsy station and was slowed by successive levels of shattering glass
Man Survived 22,000-Foot Fall Out of Bomber
Also:
"The greatest fall without "riding" a piece of wreckage goes to Russian Lt. I.M. Chisov, who bailed out of his Ilyushin 4 bomber at 22,000 feet in January 1942, after being attacked by German fighters. His plan was to free-fall to 1,000 feet before opening his parachute, thus limiting his exposure to enemy fire while still in the air. Unfortunately he lost consciousness on the way down, and never opened his parachute. Like Vulovic, he landed in snow and survived, returning to duty three months later". - link
There was also a British gunner from a Lancaster bomber who fell from his aircraft during an attack and was saved by fir trees and deep snow.
That said, I still think this guy's a loon. Nobody ever volunteered to jump without a parachute before.
I have been a user for about 10 years. This ends Feb 2014. The site's been ruined. I'm off. Dice, FU
as no one has ever survived a landing attempt without a parachute.
I don't know whether people have survived "attempts", but you can certainly survive falls from airplanes without a parachute: hitting brushes, trees, water, or snow can break your fall sufficiently so that you don't die. Theoretically, even hitting a solid, hard surface is survivable if you break the fall correctly (but I don't know of any actual cases).
Be a real downer if it doesn't work. He'll probably be in a big depression.

The trick I think is to develop enough forward speed. More forward speed develops more lift. In a regular plane, you do something called a flare as you land. As you get close to the touchdown point, you steer up (technically, you change your angle of attack). This burns off forward speed and creates lift. This guy has a lot more freedom about his angle of attack. (Him landing on his feet would be the equivalent of a plane landing on its tail.) I think it could work but, of course, I'm not going to try it. My guess is that he will still have a lot of forward velocity when he has essentially no lift left.
The more I think about it, the more I think I agree with the parent.
If you've ever seen a skydiver's jump ship (the plane that takes them up) you'll realise that there's no way you'd ever describe it as "perfectly functioning". The old joke is they make the jump ship scary enough that the skydivers would rather jump out than land with it, but not so scary that the pilot wants to do the same.
The other joke is:
"What's the difference between skydiving and golf?
In one you go "Whack! Uh oh!" and in the other you go "Uh oh! Whack!"

The Hitch-Hiker's Guide to the Galaxy has this to say on the subject of flying:
"There is an art, it says, or rather, a knack to flying.
The knack lies in learning how to throw yourself at the ground and miss.
Pick a nice day, it suggests, and try it.
The first part is easy.
All it requires is simply the ability to throw yourself forward with all your weight, and willingness not to mind that it's going to hurt.
That is, it's going to hurt if you fail to miss the ground.
Most people fail to miss the ground, and if they are really trying properly, the likelihood is that they will fail to miss it fairly hard.
Clearly, it is this second part, the missing, which presents the difficulties.
One problem is that you have to miss the ground accidentally. It's no good deliberately intending to miss the ground because you won't. You have to have your attention suddenly distracted by something else when you're halfway there, so that you are no longer thinking about falling, or about the ground, or about how much it's going to hurt if you fail to miss it.
It is notoriously difficult to prise your attention away from these three things during the split second you have at your disposal. Hence most people's failure, and their eventual disillusionment with this exhilarating and spectacular sport.
If, however, you are lucky enough to have your attention momentarily distracted at the crucial moment by, say, a gorgeous pair of legs (tentacles, pseudopodia, according to phyllum and/or personal inclination) or a bomb going off in your vicinity, or by suddenly spotting an extremely rare species of beetle crawling along a nearby twig, then in your astonishment you will miss the ground completely and remain bobbing just a few inches above it in what might seem to be a slightly foolish manner.
This is a moment for superb and delicate concentration.
Bob and float, float and bob.
Ignore all considerations of your own weight and simply let yourself waft higher.
Do not listen to what anybody says to you at this point because they are unlikely to say anything helpful.
They are most likely to say something along the lines of, 'Good God, you can't possibly be flying!'
It is vitally important not to believe them or they will suddenly be right.
Waft higher and higher.
Try a few swoops, gentle ones at first, then drift above the treetops breathing regularly.
DO NOT WAVE AT ANYBODY.
When you have done this a few times you will find the moment of distraction rapidly becomes easier and easier to achieve.
You will then learn all sorts of things about how to control your flight, your speed, your manoeuvrability, and the trick usually lies in not thinking too hard about whatever you want to do, but just allowing it to happen as if it was going to anyway.
You will also learn about how to land properly, which is something you will almost certainly cock up, and cock up badly, on your first attempt.
There are private flying clubs you can join which help you achieve the all-important moment of distraction. They hire people with surprising bodies or opinions to leap out from behind bushes and exhibit and/or explain them at the critical moments. Few genuine hitch-hikers will be able to afford to join these clubs, but some may be able to get temporary employment at them."
-- Douglas Adams, 'The Hitch-Hikers Guide To The Galaxy'
It all comes down to how much you can move an object. When you hit water the object has to move sideways to get out of your way. This is much harder to achieve than moving something down (i.e. by breaking glass) plus the glass will weigh a hell of a lot less than a few hundred meters of water going straight down, so the opposing force is a lot less.
By breaking several layers of glass one by one you slow the body down with a succession of small forces rather than one big one.
