Guys sitting in the cockpit don't always work out. During the war there was a B-52 backing out of the wash rack and another leaving a hanger after some reapirs. Who ever was at fault both aircraft were seriously damaged when the tail of one "D" model went into the nose of the other "D' model effectively putting both out of service for some time.
Not long after that a B-52 was being taken back to the reventment area to prep for its next mission when the aircraft broke free of its tug and went rolling across the flightline eventually sticking its nose into the wide depression near the taxiway. Nobody was in the aircraft at the time.
Shortly after that our squadron was given a briefing on the bomber tactics that we never knew about, seeing that we were only Security Police. One thing this officer from S.A.C. did say was with the maint. people we had at the moment, who needed needed the guys outside the fence for trouble? Not exactly a glowing review for aircraft maintennance.
