Yes, I'm inclined to agree there Maestro...the Lightning to LG, is what the Mosquito is to me, but the reality here is about single-engined fighters. Both the Mossie Lightning were superb aircraft but even I have conceded that this is about s/s fighters. The P-38's biggest problem in the ETO was not having an engine in front of the cockpit, and therefore gave no heating for the pilot....no matter how good the pilot, he's not able to give his best if he's freezing his nuts off trying to dogfight at 30,000 odd ft. In the PTO, it was the opposite, because of insufficent cooling and a cockpit hood that couldn't slide back, the pilots were virtually in their undies tennis-shoes, but they were able to dogfight, albeit most aggressively! - Even at altitude, the sun's heat through the canopy kept them hot. Anyway, the Corsair was really the first US Fighter to check the Japs Air Supremacy, the Wildcat was deadly too, but not as fast , and all that was learned from the Wildcat from it's baptism-of-fire at the heroic defence of Wake Island onward, went into the Corsair and Hellcat. The early Lightnings had teething troubles, particuarly with the tail-section, and once their engines incorporated opposite-rotating props that made the torque manageable, they were otherwise a handful for one pilot to dogfight. Also, in the MTO, Lightnings were sort-after for PR work particuarly, but also ground-attack and escort.
As Lanc points out too, the Beaufighter did superb work in all these theatres and IT'S firepower WAS formidable, they just weren't as fast.
- All said and done though, I feel the Spits Mustangs are real canidates for 'Best Fighter', so let's continue............
