I was once told that, when the luckless aircraft commander finally made it to Boscombe Down, there was a transatlantic telephone call waiting for him.
It was Curtis E LeMay. 'Old IronAss' told the poor sod, in words of few syllables, that henceforth he was busted to Second Lieutenant....
No idea whether or not this was true - but allegedly it's the sort of thing LeMay would do.....
