Crashed and destroyed 18 January 1972 in Scotland (Ben Marselis) RAF Leuchars (Doc Servo). Killed were LT COL Floyd B. Sweet and LT COL Kenneth T. Blank (Doc Servo).
55th TFS, 20th TFW, tail code "
JS".
A member of the board of investigation states that weather was not a factor, and that eyewitnesses saw the aircraft from over a mile away. He says the accident occurred because the crew failed to extend the wings forward to the landing configuration following a high altitude navigation mission. The wings were at the 35 degree sweep when the aircraft entered the GCA pattern and when the base leg to final turn was initiated, the aircraft stalled and was too low to the ground to permit recovery. It was determined that the aircraft's stall speed in that configuration was approximately 235 knots. (WK)
