I seem to remember reading somewhere that the Chipmunk was originally designed using not the Mosquito but the DH Hornet as some sort of aerodynamic template which would/could help at a time when man-hours available for design work would be hard to come by.
If you look closely and halve the number of engines, it could be true.
Has anyone else heard or read this?
I was lucky enough to have completed my CPL course on this lovely aircraft and went on to become an instructor on type for a couple of years - even had it as my first CPL type rating!
Ahhh, de Havilland................
