Something similar allegedly happened at Waddo in the late '70s/early '80s. Apparently someone had said to the Bellevue Marriott/Crown Plaza bar flies "If ever you're in England...." Supposedly, they then turned up at the Mess during Happy Hour and there were folk bailing out of the windows to escape...!
I hasten to add that this was a story I was told (I'd left the V-force by then) - so it may rank alongside the 'Shackleton making carrier approach' fable!
