    some of the flight controls necessary to re-invert it.

    Wikipedia notes:

    The B-52 aircraft, callsign Czar 52,[4] took off at 13:58 and completed most of the mission's elements without incident. Upon preparing to execute the touch-and-go on Runway 23 at the end of the practice profile, the aircraft was instructed to go-around because a KC-135 aircraft had just landed and was on the runway. Maintaining an altitude of about 250 feet (75 m) above ground level (AGL), Holland radioed the control tower and asked for permission to execute a 360° left turn, which was immediately granted by the tower controller. The B-52 then began the 360° left turn around the tower starting from about the midfield point of the runway. Located just behind the tower was an area of restricted airspace, reportedly because of a nuclear weapons storage facility.[5] To avoid flying through the restricted airspace, Holland apparently flew the aircraft in an extremely tight, steeply banked turn while maintaining the low, 250 foot (75 m) AGL altitude. Approximately three quarters of the way around the turn, at 14:16, the aircraft banked past 90°, descended rapidly, tripped power lines, and hit the ground, exploding and killing the four crew members. McGeehan was seated in an ejection seat, but according to the medical statement, he had only "partially ejected at the time of impact", it does not state whether or not he cleared the aircraft. Huston was also seated in an ejection seat and the medical statement indicated that he had not initiated the ejection sequence. Wolff's seat was not ejection-capable. No one on the ground was injured.[6]
    It's been way too long since I studied Buffs, but IIRC the missing controls enable bank-recovery.  That estimate of 5 wingspans' altitude is way too generous, by the bye ...

    •  Yes, more like 1.35 spans. (3+ / 0-)

      I have always thought that the fact that spoilers are used for bank control (if I remember correctly anyway) on a B-52 is the reason for the lack of bank recovery. For a spoiler to work, you have to be generating lift elsewhere on the wing, in particular the wing you are trying to raise. At a 90 degree or greater bank angle you'd have to be thinking more like a stunt pilot (than a moron...) to pull that off, especially considering the very low altitude.

      Maj. Kong, is any of that anywhere near correct?

      Moderation in most things.
