Fitter2:
Having recently been banned for a week from pprune for apparently "outing somebody" (who had already outed themselves) I dare not confirm your suspicions or I shall be banned for ever more.
However, DSB knew more about flying aeroplanes with finesse and flair than you and I will ever learn.
He owned the prototype Skylark 2 (especially beefed up for aeros). He never ever landed out in it and frequently appeared going past the gliding club bar, along the taxiway upside down at not a lot of feet, about one hour after we had closed the hangar doors and he would then set about doing a wonderful display having been gone for most of the day.
His aerobatic displays in the Bocian were beyond belief. I can remember him coming on after the noise and the razzamatazz of 4 Lightnings at a Battle of Britain display.
Despite the total lack of noise and razzamatazz of DSB in the Bocian, he got a standing ovation from around 25,000 spectators. His perfect square loops were a wonder to behold (not easy without an engine).
DSB was beyond the normal categories of "Above the Average", "Exceptional" etc. etc. He was one of that rare breed called "Natural Pilots". Whatever aeroplane he happened to be flying, he put it on like a "ratting jacket" (for our colonial friends, that means that he wore whatever machine he happened to be flying as if he had been born in it).
P.S. I quite enjoyed my week of being banned from pprune and so did my local landlord. My sex life improved also!
