He did not pass the speed of sound :(
- MrFoof 14y agoIndeed, he didn't break the speed of sound. When he hit around an estimated 729mph, he was spinning a fair bit. It looked as if he made the decision to attempt to stabilize (I think he mentioned during descent that he thought he was going to pass out) himself at the cost of not breaking the sound barrier.
- monochromatic 14y agoSurely the speed of sound is much lower at that altitude, since it's so cold. Are people talking about the sea-level speed of sound?
- arrrg 14y agoOn their website they say that the speed of sound would be about 690mph at the height that he was expected to reach it, not 768mph – that speed just applies at standard temperature and pressure. I would very much like confirmation on that point, but it seems to me that pointing to the 729mph you saw is no such confirmation.

- k-mcgrady 14y agoI don't think it has been confirmed yet, he was pretty close.
- thomasilk 14y agoAt the moment it looks like he passed it.
- agumonkey 14y agoOn the live stream they said he topped 1173km/h. What speed was the target ? I mean speeds are defined in air and 'normal condition', there was almost no gas around him during his fall right ?
- Lapsa 14y ago1,236 kilometres per hour (768 mph)
- izend 14y agoSpeed of sound has a non-linear relationship with altitude. http://www.wolframalpha.com/input/?i=speed+of+sound+at+100000+feet http://www.wolframalpha.com/input/?i=speed+of+sound+at+10000...
- jonmrodriguez 14y agoWith altitude. Non-linear with attitude would mean w/ angle of attack, which would be fascinating.
- mittermayr 14y agohe did, just confirmed and verified by the notary.
- stordoff 14y agoAccording to the press conference, he hit 833MPH (Mach 1.24).
- tripzilch 14y agoIt was also not the "edge of space".
