Talk about coincidende: yesterday I was doing a research about this plane...
There's no video, but there's a picture:
Continuing the XB-70 facts:
The incident involving 20207 was a publicity stunt for General Electric, who built the engines powering the Valkyrie, and the 4 other aircraft.
The aircraft that impacted was a F-104. The pilot died on impact. Only one of the two pilots from the XB-70 ejected, and suffered a broken arm when the clam-shell doors slammed down on an imporperly placed arm (the XB-70 had clam-shell style ejection seats).
The operational B-70 would've had a crew of 4, with the entire cockpit ejecting as a whole in case of emergancy.
A third XB-70 was in the works when 20207 crashed. NASA planned to use the Valkyrie as a test bed for experimental propulsion systems. However, after the crash, it was scrapped.
While many think the crash of 20207 was to blame for the cancellation of the Valkyrie, its fate was sealed before hand. Improved SAMs, expensive operational costs, and a very large radar signature (created by the intake's air damn) are what did it.
North American is now owned by Boeing, and is effectively dead.
