When i was based at 615 (just up the road at Kenley) rumour had it that Bill would do inverted circuits in the Swallow !! Wish I had met him.
The Comper Swift G-ABTC had been rebuilt at Tangmere when owned by the Station Commander J A Kent.
Tangmere and Kenley both classic battle of Britain airfields, and both got hammered. Kenley never extended for jet operations whist TG got a much longer runway. When Al Pollock flew his Hunter under tower bridge he had taken off from TG.
