Skydiver plans head-first freefall from the edge of space in dizzying bid to break Mach 1
By IAN SPARKS

He will leap head-first from a weather balloon 25 miles above Earth and plummet at more than 1,000mph with only a parachute for company.
He will face external temperatures of minus 100c while inside his carbon-fibre suit it will be a stifling 65c - almost 150 fahrenheit.

And most amazing of all, Michel Fournier is actually looking forward to it.
The daredevil Frenchman, a greyhaired 63-year-old former paratrooper, aims to become the first person to break the sound barrier in free-fall.

As he plunges through the stratosphere at supersonic speed, he also hopes to break three more world records - for the longest sky dive, the highest parachute jump and the highest altitude achieved by a human in a balloon.

Despite the intense cold outside, his £35,000 suit will heat up inside when it meets air resistance. His crash helmet will have its own air supply and reinforced ear pads to protect him from the sonic boom as he breaks through the Mach 1 sound barrier.

Fournier was one of three candidates selected in the 1980s to take part in a military endurance test to see whether a parachutist could descend from 125,000ft - almost 24 miles.

The project was shelved in 1988 - but he decided to go it alone. He hopes to make the jump over the Great Plains of Saskatchewan in Canada some time next month, weather permitting.

"I would be lying if I said I wasn't afraid, but I am also very excited," he said."It really is a leap into the unknown."

After leaping from the balloon, Fournier believes he will break the 760mph sound barrier within 37 seconds.

The lack of friction due to the thinness of the air will mean he can attain a much higher terminal velocity, and his team of scientists estimate he will reach the top speed of 1,113mph before he is slowed down by greater air resistance.

His parachute will not open until six minutes, 25 seconds after jumping and he will finally reach the Earth after around eight and a half minutes.
The record for highest leap was set in 1960 by a U.S. Air Force test pilot, at just under 20 miles.

1. Hope that chute opens at those speeds.

2. I'm betting he boils.

Even if the chute does open, whiplash anyone?

He'll probably catch on fire like those space capsules that carry returning astronauts (Apollo 13)

I sold my house, my collection of weapons, my stamp albums and my military medals to get this project off the ground after training for more than two yearsIsn't this what people do when they're preparing to die? Or something to that effect.

physics says he can't reach that speed.

non-enhanced terminal velocity is between 100-200 mph depending on body position.

Is that in the lower atmosphere where there is significantly greater friction or above it?

I looked it up, this guy almost broke the speed of sound.

Wasn't that just a bungee?
Also plummeting at 1000mph sounds physicly ridiculous. Both in possibility and survivability.
Bon voyage imbecile (had to)

I read the article I'm just skeptical of the accuracy.

I'm no physics major but how much of a difference in friction can there possibly be? It's still air.

There's a huge difference.

A fraction of it.

Yeah I saw a program on him before and it was amazing to me the balls it took to jump from that height. I knew this has happened before.

He won't have enough O2 present to set off the combustion reaction, and by the time he does, Earth Science + physics predicts that his velocity will have slowed substantially enough to offset (some [most {all}]) possible combustion reactions. I'm imagining they've pre-planned an extremely high heat potential exterior for whatever it is his gear is made out of. What with ΔT bouncing around like a B-ball.

Yeah. His suit must be extremely dense and ridiculously well-pressurized, which prolly costs the pretty penny he earned by selling all of his stuff.

Vertigo anyone?

All I can say is I would like an update if this is done.
