from nose to tail of space shuttle is just enough distance to create two sonic booms..

@gyptax Actually every sonic boom consists of two bangs. The pressure wave coming from the aircraft creates a "boom" when the pressure surrounding the person suddenly rises to that of the wave and then suddenly droping back to the surrounding pressure.

@anyhandleleft : yep.

Technically it's always a twin sonic boom, the distance between nose and tail is what makes it really matters. Just search for concorde sonic boom, you'll hear double one there too.

@garrrbo I don't know how much you know about flying, but the boom you hear is when the shuttle passes overhead on the downwind leg of its approach (parallel with the runway). Main gear touchdown is only about 3 minutes or so later. It touches down at about 250 mph, so it's movin' pretty damn good right up until final approach.
