"Bay" Adams of 3 SQN RAF (mentioned in "The Big Show") once related the tale when they were flying Tempests in a large Wing gaggle over Kiel to mark the end of the War.
His engine seized and had to put it down in a field. Good landing, unstrapped and climbed out. He saw a Brit army officer at the side of the field beside his jeep. He motioned to the army chap to come over, but the pongo didn't budge.
"Bugger me" said Bay, carried over his parachute pack to where the soldier was with his jeep.
"You could have come over to pick me up, mate" said Bay.
"My dear chap, well I couldn't really" replied the brown job. "You've just walked through a minefield!"
