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.

one small correction, the SR-71 didnt carry the drone, it was the YF-12 version A. damn near the same bird though.

[Blackbird101]

When Lockheed converted the YF-12 to carry the Drone, the plane was then called the MD21.

MD standing for Mother/Daughter.

R.I.P. to veterans of cold war...many have given lives from both parties. My uncle was ready to shut down SR-71

When released, the drone could not break through the shock wave wall of the MD-21. It basically bounced off the shock wave and back down unto the MD-21 essentially cutting it in half (with the assistance of the very high dynamic pressures involved at mach 3). They had performed this same routine many times in a .9 dive but never in level flight. This flight marked the end of the program. It was called off by the narrarator of this video - Kelly Johnson - the designer of the beautiful P-51.

@Mrpl3973 Originally to carry a high speed nuke

@Nickomfacc at mach 3, if something pushes the back of the plane down and the nose goes up, the sheer force of resistance will break up the plane...

What a beautiful aircraft...

[Nickomfacc]

what caused it to break up, what actually happened?

[Mrpl3973]

What was the drone for?

[DeKarle1992]

They both survived the ejection and landed on sea, but Ray Torick opened his helmet visor by mistake and his suit filled up with water which caused him to drown.

For God sake why were they flying so close together? Once they launched the darn thing, why didn't they peel away? It looked like they ran into it from behind? I heard that the early SRs had problems with compressor stalls until they figured out how to move the spike properly. Maybe the D21 had a compressor stall and plowed backwards into the M21.

@mantishrimpruler2 FASCINATING. Thanks for that info...just fascinating.

Long live the SR-71, its pilots, its managers, its designers, its constructors, and let's not forget this tragic incident. *snif*

@Blackbird101 actually it was based on the a-12 not yf-12, the yf-12 is the prototype fighter version of which only 2 were built. no blackbird was ever converted to carry the d-21 drone, the 2 m-21s built were built seperatly on the line and built from scratch. but it took the design of the a-12. the plane was called an m-21 and the drone is called a d-21 but when together the combination is the m/d-21 not the plane.
