Skydiving Across the English Channel
loonix_gangsta writes "Felix Baumgartner, an Austrian, has become the first person to skydive 35 km (22 miles) across the English Channel. Wearing a jumpsuit with a large carbon fin strapped to his back he reached speeds of up to 360 km/h. The whole flight took approximately 14 minutes. The newsitem is being covered by the BBC, SkyNews
and CNN."
He must have accelerated slowly.
.23h == 82.8km
14 minutes is ~0.23 hours. 360km/h *
What interests me, is how he managed to accelerate up to the 360 kph mark, and slow back down, without the sharp sudden stop that I associate with skydiving. (C'mon you know you saw him bouncing along a field until he smacked into an old hardwood)
I assert that my comment is only my opinion, not that of any employer, past, present or future.

"On the third and last jump in Excelsior III on August 16, 1960, Captain Kittinger jumped from a height of 102,800 feet, almost 20 miles above the earth. With only the small stabilizing chute deployed, Kittinger fell for 4 minutes, 36 seconds. He experienced temperatures as low as minus 94 degrees Fahrenheit and a maximum speed of 714 miles per hour, exceeding the speed of sound. The 28-foot main parachute did not open until Kittinger reached the much thicker atmosphere at 17,500 feet. Kittinger safely landed in the New Mexico desert after a 13 minute 45 second descent. Project Excelsior successfully proved the new parachute system would solve the problem of high altitude escape by crewmen."
