Rocket Sled land speed record

This is an old video I found somewhere. The rocket sled hits a top speed of 10330km/h (mach 9.74) (6400+ mph) on a 16 kilometer rail. Used to be a world record.

The part in the middle of the video is a different segment and talks about John Stapp's acceleration to 1017km/h in 5 seconds and how he temporarily lost is his vision.
Then it goes back to the main segment about the unmanned rocket sled.

space shuttle does mach 25, speed is irrellevant it's acceleration/deacelleration that can kill you.

Not true. DO not confuse mach with g force. Astronauts do many times mach 9 and suffer no harm at all.

This looks like fun. I think I'll make one myself actually.

I mean... how hard could it be (must be read in Jeremy Clarkson's voice).

he pulled around 42g when he came to a stop

According to wikipedia, the current record holder for rocket sleds stands at Mach 8.5

@efendulov you have ignored the fact that with modern tech it is near impossible to accelerate an object to mach 10 at less than ten thousand meters true altitude. it is even harder to mantain this speed, even if the craft is going at this speed only a tiny fraction of the way. also, if there were a person in it as the video indicates then they would have died because of immense wind buffeting.

@Teh1337bix I keep getting this explained to me every once in a while since my post have been thumbed up a lot for some reason, but if you scroll down to where I first posted this, you'll see I foresaw this objection and wrote "however going hypersonic like this inside the atmosphere would ignite you ;D"
