I am researching military aircraft crashes with a general or admiral or "flag officer" at the controls. For example:
17 January 1968, Minot AFB, ND, KC-135A, over-rotated in blizzard after waiving weather minimums.
9 September 1972, Randolph AFB, TX., T-38A, crashed on takeoff after boasting of an "aerobatic departure."
26 April 1984, Nevada Test Ranges, MiG-23, crashed during flight after waiving conversion training to fly the airplane.
I am sure there are others, and would especially be interested in those of non-U.S. forces.
