The thing with dropping the 110G and the Mossie is where do you draw the line?
Of course its subjective - but the way I figure, no one uses the 110 as an ATA fighter and very few use the Mossie for that role.
I cant really think of any other eligible aircraft I would not consider a "fighter."
Personal opinion and suggestion, only.
Maybe an easy cutoff (if it were even a popular idea in the first place) would be single-seat AC, only.
