IIRC, there a rock ape Flt Lt at Coltishall back in the 1970s who had - somewhere - a stash of C4 or equivalent.
He had a violent antipathy to anyone who left a party early when it was in full swing and would set out to roust them from their rooms. People learnt not to lock their doors - whether alone or accompanied - as this usual resulted in a sharp crack and the door falling inwards sans hinges and lock.
