Thanks ever so much for that one ... I really was in need of a lift in this constant chasing down of multiple personality sufferers .... my day is now much brighter ..
I did read a long time back a tale which suggested that the early military aviation side of things had pilots (often with a cavalry background) "mounting" their avian steed from the left .. which led to the LH seat thing in fixed wing aircraft ... no idea whether this is kosher but it makes some sense, I guess ?
