The night before Graduation at Feltwell, one of the guys brought his motorcycle in to the Mess and started driving it briskly down the corridor. As he approached the end, where the Bar door was, he applied the brakes. The hall carpet followed him, with no discernible deceleration, as he ploughed in to the end wall, just missing our flt lt RAF Regt DS who was leaving the Bar.
ISTR he wasn't on the Parade the next day.
