I guess he was gone but I did want to correct one of the many his misunderstanding and that was that the P-51, 51A, and early P-51B had much better range than the F4U and F4U-1 (not the 1D). The internal fuel of the noted F4Us was 350 gallons while the noted P-51s only had 180 gallons. F4U-1D and on had 237 gallons internally and the later P-51B had 270 gallons internally. So early in the war the F4U would have had a better range than the early P-51s, later in the war the P-51s would have a significant range capability.
