Halcyon days... 69-71 on ULAS at White Waltham on the venerable Chipmunk. 145bhp, if I recall, which was the same as a Vauxhall Cresta. Fri nite in the mess, Sat morning hungover, strap in, pull the chain, face full of cartridge fumes, taxy out, launch off to overhead the White Horse on Lambourn Downs, aerobat oneself silly, trundle back to White Waltham, attempt a three-pointer (and bounce), repeat same after lunch, then back to the mess for afternoon tea and toast, while waiting for the bar to open. Repeat same on Sunday. And get paid for it!
