SR71 Sistership, The MD21 Blackbird Accident

I compiled this video from long lost footage of the Mach 3 fatal accident involving the D21 Drone and the mothership called the MD21(an SR-71 Sister Ship). The Lockheed Taqboard Program was cancelled after this accident. Video is narrated by Kelly Johnson, Designer of the Blackbirds.
