I've sat in a Bf-109, P-51, Sea Fury, and Corsair. I remember the -109 being the most crampped but I didn't feel that uncomfortable (I think I'm the same weight then as I am now, 5'9" 175/ 180 pounds. Lots of room in the Corsair, I remember the P-51 and the sea Fury about the same. The Post War stuff I've been in were all a lot larger with the exception of the back seat of a MiG-15 UTI, that was pretty cramped.
