The XCOR X-Racer Prototype, built for the Rocket Racing League was flown at the AirVenture 2008, and XCOR just released a couple of videos. This is an onboard camera split view from one flight and its a lot of fun to watch. The pilot is Richard Searfoss, Astronaut (former) and Col. USAF (Ret.), and the Flight Test Engineer is Mark Street.
Below is a music video showing a sped-up version of getting the X-Racer ready to go, and the flight.
