I turned up for happy hour and was asked by the Stn Cdr why my uniform was so creased. I told him that spending an afternoon in a sweaty cockpit in a parachute harness tended to do that, Sir.
It had been a booming day, I was at a lose end so I had negotiated and aerotow in a lunchtime gap in the UAS traffic, which they agreed provided I did not return before UAS stopped operating.
