MT Office at RAF Rheindahlen was in a decrepit old building [manned by decrepit old Germans in the main] and the hatch to which 658s [? number correct?] were proferred and keys issued was low, requiring a crouched posture even for one vertically challenged as I.
The hatch was guarded by a low beam 1m in front, easily noted on the way in, but forgotten in the euphoria of actually getting the keys.
