Serious? :embarrassed: that's more shocking than the fact he made it alive. I was expecting some real big forces on his body.

The force you'd feel on the ground at that speed are caused by friction with the air. At such heights there's not much air, so friction is only marginal compared to low altitudes.

Only forces he would have felt are centrifugal forces due to spinning. Well, and the lack of pressure if he wasn't wearing a suit.
 
To get an idea how fast mach 1 actually is:



Felix Baumgartner and the Thrust SSC have one thing in common: they're both Mach 1 world record holders.

I wonder who will make it to 1000mph first, Felix or BloodhoundSSC?

Well, as Felix said that this is his last ever jump, and has now retired (well, from base jumps, sky dives etc. He is going to be a helicopter rescue pilot)

Bloodhound will be another history maker! Roll on 2014!

Have to quote it. The whole moment was just breathtaking. It almost brought tears to my eyes.
 
Tomorrow would be the day I'm missing Physics class... We're probably going to do something really interesting about this and I'm missing it.
 
not sure if its been posted but I read he went 70mph faster than the land speed record. Just incase people are struggling to comprehend the speed!
 
The force you'd feel on the ground at that speed are caused by friction with the air. At such heights there's not much air, so friction is only marginal compared to low altitudes.

He was talking about breaking Mach 1, which isn't related to friction. But the same thing applies. The air density was so low (which is why Felix went so fast in the first place) that the feeling of pressure difference before and after the shockwave probably wasn't much.

For a really sharp body, breaking the sound barrier feels like a sudden jump in drag, however things can be different for a blunt body like a human body. Local regions of flow would go supersonic before Felix actually went supersonic and this would make it harder to feel the difference in force before and after as the build up of drag would occur over time and not all at once.
 
Helmet cam footage is mental. Looked scary enough to see him tumble from the long-range camera, but on-board it looks even worse.
 
Slim Jim responds to Felix's jump by setting a different world record:



EDIT: Felix's hidden audio recording during the fall leaked. (:lol:)

That's because the air is so thin. He was falling faster than terminal velocity in "our" air.

it's because he was wearing a dead suit (Felix's words - presumably another name for his space suit)
 
have a physics assignment on this ,any pointers on where most of the information related to the jump are?
 
Tonight on BBC2 at 8:30pm UK time there is an hour and a half documentary on the run up to and the jump itself.

Radio Times Review by: Terry Payne
Felix Baumgartner is obsessed with leaping from high places. He calls it a curse. If you watched his recent fall to Earth from the edge of space you might think it better described as a blessing. A BBC crew has been following Baumgartner for the past four years through every giant leap and equally sizeable setback of his training. There are scenes of intense tenderness – with his mum and with his mentor Joe Kittinger, whose 1960 100,000ft jump record he aims to break – and moments of tension as delays, sackings and catastrophic equipment failures cause Baumgartner a serious crisis of confidence.

Then there’s the jump, with footage shot exclusively for this film. It could easily have been Baumgartner’s obituary; instead it’s a glorious tribute to a daredevil endeavour that demands the creation of new superlatives.
 
That was an amazing documentary. I didn't realise they cut out the bit of the ascent where he was worried about the visor. Fascinating also to see Felix pulled out of the project at one point.
