better question: why did the RAF move over to regular sticks?
nothing ergonomic about the vertical stick, i mean when you're cruising in a car with one hand on the wheel, does you hand go naturally to the 1-2 oclock position, or to dead 3 oclock with your grip vertical?
afaik the usual pilot position for a kill in a spitty would have been hunched down into the sight, knees under your chin with your feet on the upper set of rudder pedals (reduces G-effects) with both hands on the stick, elbows braced hard against the side of the cockpit. bit different from lounging at a desk
