The truth is, the only REAL options for a perked USAAF ride are the A-26, and the hated B-29.
Ahem. I believe that there is a contender for a USAAF perked fighter, the 20mm armed P-51. Now I know much-ado has been a-done regarding this bird (mostly negatives); so if you want to think of this offering as bait and reply with blah-blah-blah, go right ahead.
I have a 102 degree fever, my head hurts, my stomach is rebelling, my bowels are fluxing, and my nose is dripping snot like Victoria Falls drips water. Go ahead and flame me, you won't make me feel any worse than I do and my meds will keep me from seeing reality from your POV.
