970 was lost on June 17, 1970.  Just after an in-flight refueling with KC-135Q #59-1474, the SR-71 suddenly pitched up and collided with the tanker.  RSO Maj. Mort Jarvis bailed out unharmed, but pilot LtCol. Buddy Brown broke both his legs during the ejection.  59-1474 managed to make it back to Beale AFB safely in spite of suffering what Brown described as "a severely damaged horizontal stabilizer."  40 years later, it's still flying with the Michigan Air National Guard.
