Frenchman Plummeting 40 Kilometres From The Sky Will Break Sound Barrier, World Records
Posted by Gizmodo US Edition at 11:00 AM on May 25, 2008
Michel Fournier is about to make the greatest leap of his, and anyone else's, life. On Sunday, the 64-year-old retired French army officer will fly almost 40 kms into the sky in a giant balloon, step out of a pressurised capsule and plunge headfirst towards the earth, soaring through the atmosphere for an estimated 15 minutes.
A lot can go wrong when you're trying to reach 40 kms up in the air. At above 12kms, there's no longer enough oxygen to breathe. At 19 kms up, the air pressure can cause blood to boil. Fournier will be taking the trip in a special space suit, but if it malfunctions, he'll be dead within seconds.

If he makes it, Fournier will set records for falling the longest, farthest and fastest of anyone in history. The fall will be the cumulation of 20 years of research and physical and emotional preparation. To pay for his training and equipment, Fournier has sold almost all his belongings and spent roughly US$20 million, mostly raised from private donations.
Fournier has insisted that he's not free falling to break world records. And though the data collected from the jump could have ramifications on aerospace escape procedures, many argue that there is very little to be gained scientifically.
Rather, this experiment probably has its roots in something much more basic and instinctual, despite its decidedly high-tech makeup. Fournier is out to fulfil his all-too-human need to find and, hopefully, exceed his own limitations. [NYTimes and Le Grand Saut]

Poor lil fellar never had a chance... perhaps he should attempt the world record for knot tying first?
"French skydiver Michel Fournier's bid for a record-breaking parachute jump from Earth's stratosphere was aborted Tuesday when the balloon that was to carry him into the far reaches of the sky slipped away from his flight crew."

When Col. Joe Kittenger made his freefall from approximately 124,000 back in 1960 he did break the sound barrier. Just so everyone knows, the sound barrier at such high altitudes is not 741.2 MPH as it is at sea level, it is a lower airspeed, not to be be confused with his "true airspeed". Also, his main chute was automatically deployed at 24,000', this after over a 4 1/2 minutes freefall!! Col. Kittenger wrote a book with National Geographic called "The Long, Lonely Leap". Good luck in finding a copy. It took me 12 years to find 2 copies to have the Col. sign for me. I would bet that the Col. is helping along side with the hopeful success with this jump. One of the reasons that the Col. was doing these gigh altutude jumps was to help develope the pressure suits used for high altitude flight, etc....one of his gloves failed during his highest jump. Suit of today have changed quite a bit.

@Synthfilker: Of course you can hold your breath against that sort of pressure. That's silly. Muscles don't work in one direction only. Internal or external pressure makes no difference at all.
Even the people at NASA admit that it won't really affect you. They say it will probably damage your lungs in some unspecified way, but that no real catastrophic damage would happen.
@wagnerrp: You're VASTLY mistaken in that pressure calculation. VASTLY. Water exerts far more pressure than atmosphere ever does. The entire change in pressure of leaving the whole atmosphere is a difference of about 101 Kilopascals. From 1 atmosphere to 0 atmospheres. Which is the change in pressure you get when you descend maybe 10 or 11 METERS in water. At 100 feet you get somewhere around 400 kPa pressure, which is very roughly FOUR atmospheres of pressure.

@Pope John Peeps II: It has nothing to do with the difference in pressure, but rather the ratio. At that altitude, the air pressure is somewhere under 1kPa (compared to 101kPa at sea level). That is a change in pressure as if being at over a mile underwater. If you take a lungful of air at even 100ft down, you will damage your lungs if you try to hold your breath up the surface.

@Pope John Peeps II:
wow wow wow. Not true, at all. Firstly one atmosphere of pressure is added every 33 feet of seawater, so unless you have a really deep pool, or you fill it with something really dense you are not holding your breath against 2 atmospheres of pressure. Secondly, as you descend the volume of your lungs decreases in response to the increased pressure outside, so you essentially have the same pressure outside to in, in order to actually hold your breath against one atm of pressure you'd have to go down to 33 feet, breath in fully, then hold your breath and come to the surface. There's a reason you are told *never* to hold your breath on ascent while SCUBA diving, lungs aren't strong, at all, and you'll end up with air in your blood stream, which is bad.

@Pope John Peeps II:
You DO understand the difference between "vacuum" and "pressure" in your example, don't you? It's far easier to hold your breath against pressure (in the pool) than it is against vacuum.
Odds are, you can't even hold in half an atmosphere of positive pressure differential in your mouth... like when you try to blow up a "stiff" balloon. Your cheeks puff out, and your lips can't maintain a seal.
Holding your breath against a vacuum? I predict an epic fail.

But: I wish him "merde" :)

@wagnerrp: Well, that's not really true either. You can hold your breath against vacuum. One atmosphere of difference in terms of pressure is REALLY not that much. If you dive to the bottom of your local pool, that's about two atmospheres of pressure, and you can hold your breath against that.

On Saskatchewan. Two Americans were traveling through Canada on the train when they arrived at a Station. One guy got off to see where they were. He walked up to a man and asked, "Hi, can you tell me where we are?" Dude replies, "Saskatoon, Saskatchewan."

@Open_universe: Joseph Kittinger did break the sound barrier. The reason he could do it was because the thin atomsphere. With such a thin atomsphere there is much less resistance and practically no boom. Once he god down to the thick atmosphere his speed would have slowed.
This guy who is trying to do it and reengineer the whole thing is stupid. This was done in 1960. Not much has changed since then, other then tracking, etc. But I guess they might want to one-up him. But $20M is just dumb.

@bl1nk2much:
It shouldn't have to be any stronger of a parachute than if he was dropped at 40,000 ft. He'll reach his terminal velocity, which will decrease as he descends due to more air resistance, which should be fairly consistent, then at a similar altitude to a HALO jumper, open the parachute. In other words, the air resistance will slow him down enough that he shouldn't need too much of an extreme chute to make it down safely.

@SpeedyGonzalas: Thanks for the video. Very pretty, but somehow I don't think that's the official nasa footage ;-)
I heard the original nasa guy talk - very inspirational (go maker's faire!!). He said that they had to combat a potentially very lethal spin that's not encountered in normal parachuting: the person, facing down in the normal pose, would spin about their center, causing all their blood to flow to the brain and feet. I think they used a carefully constructed drag chute to stabilize this portion of the drop - if that chute would have failed, he would have been dead long before he could get a chance to deploy the main chute.

I've been hearing about this for years now, and every time I hear it, he's been years in the process of research and preparation, each time ready to make an actual low-orbit jump soon. There have even been mentions of people that might pose as rivals at various points. A quick Google search brings up names like Cheryl Stearns, Rodd Millner, and Steve Truglia.
I'm just waiting for when he finally takes the plunge. It might be a record-breaker if it ever actually happens, but it certainly won't be the first jump made from an extreme altitude.
@Sora57, snowninja:
Did you ever consider that maybe the scientific data gleaned from this might just be worth millions? If the world is screwed up because a man managed to collect enough funds to pull a stunt like this, then let's shut down NASA, the JPL, and the ESA.

NASA is apparently interested in the results of the jump, so it's possible some of the $20M came from government coffers.

@Open_universe: That's the transonic region. Depending on the aerodynamics of the vehicle, that's usually around .9 to 1.2 Mach. That's the real limiting factor for airliners as they have to stay below that (as opposed to below Mach 1). You end up with localized areas that go sonic. The air becomes very turbulent, and shock patterns becomes erratic.
On a rigid structure, this can be designed around. Most modern aircraft fans and compressors operate transonically.

Guys, what I was referring to is that, when an object breaks the sound barrier, it has to overcome the pressure wave that builds up around it. In truth, no plane flies AT the speed of sound, since that is the point of greatest instability. One has to break THROUGH the speed of sound, and flight then becomes stable again.
I think I read somewhere that when the US Air Force was examining wreckage of planes that had hit and stayed at the speed of sound, they found structural damage and lots of little holes, as if the pressure waves had ripped the plane apart. Yes, "in a land-based car" men have broken the sound barrier, but it might be a different story in a pressure suit.
I guess we'll find out soon enough.

And 12 miles up, should his protective systems fail, his blood could begin to boil because of the air pressure, said Henri Marotte, a professor of physiology at the University of Paris and a member of Fournier's team.
Uh. What the fuck is this guy talking about? Blood doesn't boil at less than one atmosphere's difference. Not even at one atmosphere's difference, in vacuum. At most, capillaries close to the skin's surface would break a little, but blood boiling is total bullshit.

@Windhawk: Terminal velocity changes with altitude. More specifically, terminal velocity changes with air density. Drag is directly proportional to air density, so less density, less drag, and higher terminal velocity.
From the opposite side, the speed of sound is proportional to the root of temperature. It is considerably lower at altitude than it is at room temperature.

At 32 feet per second per second how do you break the sound barrier? If you are in freefall you hit terminal velocity well below the sound barrier.

If he's travelling faster than sound and he screams, will he hear it?
Reminds me of an old joke: what's the last thing to go through a fly's mind when it hits your windshield? It's asshole.
Good luck dude. Don't be that fly.

@Kareem King:"1. Man survives jump, eaten by bear"
I think it would be more accurate if it was..."Man survives jump, eaten by shark"
since, you know he'll probably land in the water.

@Open_universe: It's been done in a car, too (or at least a land-based jet):
"The current absolute (or unlimited) [land speed] record holder is ThrustSSC, a twin turbofan jet-powered car which has achieved 763 mph (slightly under 1228 km/h) over one mile, breaking the sound barrier." --Wikipedia

Based on the information above, here are 10 headlines to accompany his potential death.
10. World record set for longest suicide.
9. Man locks self in capsule, floats into outer space.
8. Man in fire retardant suit catches fire.
7. Unidentified aircraft shot down by military. People continue to live.
6. Sky diver hit by jumbo jet.
5. Parachute proves useless for man rocketing to ground.
4. Death drop, 15 minutes without parachute.
3. Man dies of shitting, heart attack.
2. Man jumps from space, lands on flagpole.
1. Man survives jump, eaten by bear.

Google "Joe Kittinger", he's the Air Force officer who currently holds the freefall record. The Air Force discovered that he needed to have a small drogue chute deploy relatively quickly after jumping out of the high altitude balloon as a human won't just go straight down head-first, as the diagram above implies, but rather will spin around. Stability is very important.
I also feel that it is STUPID of this guy to have squandered $20 million for this feat. Bang some supermodels instead, fercrissake!

a guy i know said that in one of the of the first types of outter space missions, a man, wearing a home made space outfit, got into a hot air ballon, and got high enough so that he could jump from the hot air ballon into a part of the atmosphere that was high enough so that he could float. then i think he somehow pushed himself forward (could he have swam) towards the earth, and opened up his parachute.
that little story, whether true or not, reminded me of that is all.

Posted 11:38 AM 25/5/08
holy fuckin shit!
and btw, he'll only be travelling that fast when he's really high up. as he gets closer to earth the atmosphere will get thicker, air resistance (drag coefficient, whatever) will increase, and he'll slow down (hopefully without turning into a fireball first). If his chute opens around the same altitude as a normal skydiver, at that point his speed would just be regular terminal velocity (200km/s)

This guy keeps trying, and every time, something goes wrong. Given his perpetual scrappiness, hopefully this time he'll make it. His scrappiness, however, is itself a risk given relatively modest funding for such a high tech challenge.
One cool aspect of a jump this high is that there is no wind whipping by you at first, flapping your suit and whizzing by your head, as there would be on a typical jump. Since the atmosphere is so thin that high up, you just fall. There's not enough air to resist, whip and flap... just a clean, fast, silent drop until the atmosphere thickens out at lower altitude. Assuming he makes it that far.

@CutePuppyz: How can there be no gain from surviving this? This would be the ultimate thrill. I would be afraid that even sex would be boring after that. Okay, so that ain't so much a gain as it is a loss. Nevermind.

Wasn't a very similar stunt pulled off way way back? I seem to recall seeing something about it on Discovery. That guy also used a balloon and had a "space suit" to stay alive.

Betchya he depressurizes the capsule before he jumps.
Also, to the question about what happens to the capsule after he jumps, the reason his last attempt failed is because the charges that are supposed to separate the capsule from the balloon after he jumps fired while they were filling the balloon and it floated away before he ever got off the ground.
So the intent is to return the capsule to the ground by separating it from the balloon. I can just see it now - the guy lands safely, is greeted by the press and adoring public, and then is crushed by the capsule on its way back down.
