Fascinating video of SpaceShipOne with telemetry data from its history making flight on 21 June 2004.
During the flight there appears to be many small problems, but at the end of the day they accomplished their goal. Take note the audio seems to be a delayed 4-5 seconds.
Dropped from WhiteKnightOne at FL459
Top speed during climb Mach 2.48 (not sustained, mind you).
