Damaging buildings, now I was good at that, I was temporarily assigned to an engine bay between squadrons for a month or so, I was responsible for shuffling about engine modules and their cases... Having to move a module I drove over and under it with the forks and started to lift it, blimey it was heavy, heavier than I remembered, but I persevered, forks straining to lift it then all of a sudden bang and it was up.. Stopping I looked behind the packing case to find I'd also lifted the cast iron heating pipe that ran the length of the building fracturing it... Oops, but good old PSA had drained the system for the summer... Thinks to self, own up and take the grief for a genuine accident or leave it for them to find in the winter... I do wonder when they found it..
