This 12-minute video alternates between being stone boring, abstractly artistic, and damned thrilling: a camera mounted to the right SRB (solid rocket booster) of the Discovery (STS-121), from about a minute before launch to detachment at about three minutes in, to splashdown in the Atlantic at 7:30 or so, and then another 4-plus minutes
of floating underwater.

More videos can be found here.  But that page isn’t persistent.  The underlying movies seem to be addressed 1 2 3 4 5;
I believe #2 is the one linked above.

Interestingly, this was the 32nd flight of Discovery, and the 115th space shuttle flight.  I really had no idea there had been so many.
