I know of this ruling because of a pilot in the Air Force whose name was Flt Lt Hugh Rigg (his sister was the actress Dianna Rigg), he was a test pilot at Farnborough, and he'd had to bang-out of two test aircraft when I first heard of him, and the next time he had to leave a stricken aircraft the cunning bugger rolled it onto it's back, undid his straps and fell out. He reckoned that was the way to get round the three-strike rule, and it worked for a while.
