While re-reading Lundstrom's The First Team at Guadalcanal I found this interesting statistic. Referring to the period Ferbruary 1, 1942 to June 4, 1942 "...in direct confrontations between the two fighters, fifteen Zeros secumbed as opposed to ten F4Fs (seven pilots killed.)" The conditions under which they fought were similar and the only varibles I can think of were possiblly the skill of the piots and certainly the tactics. It seems that contrary to conventional wisdom that while the Zero was better in a dogfight, the Wildcat was the better overall fighter.
