But if that was the criteria wot about the BBMF's Chipmunk, DC3 and Lancaster?
Pilots who have been brought up on a diet of tricycle undercarriaged aircraft need to learn how handle a tail-dragger. The Chippy is a tail-dragging trainer so very suitable to the task or do you suggest letting new pilots to the BBMF loose on their own in a high-performance, single seat aircraft?
The DC3 is likewise used to provide new pilots with experience handling a large, multi-engined tail dragger before letting them loose on one of only two airworthy Lancaster bombers left flying.
But I'm sure an experienced, air-minded person such as yourself doesn't need an ex-stacker to explain this sort of stuff.
The Lancaster? Yes its not strictly a Battle of Britain aircraft and hence, when it joined the Battle Of Britain Flight in 1973, the extra word 'Memorial' was added to the unit's name. Up until that point the Lancaster had been operated by 44 Sqn from RAF Waddington but it was deemed more sensible to have one unit operating all the RAF's historic aircraft.
