What are the odds on the same Lancaster crew taking out Glen Miller......?
Seriously though, I read about a Lancaster crew debrief when an inexperienced gunner admitted to his captain that he thought he had seen a night fighter close in cloud, but when it came into clear air a few seconds later he saw that it was another Lancaster. His captain gave him a savage dressing down - if he thought it was a night fighter then why didn't he shoot at it?
Loyalty in those times was to the crew - not the Sqn or the RAF. Those who moulded as a crew survived. Had the gunner who is supposed to have shot down Gibson hesitated, and it had been a night fighter, then they were gone. Gibson should have kept clear.
