I don't know about WWII or Korea, but I recall reading that he missed becoming an ace in Vietnam when the AIM-4s on his Phantom II failed on what would have been a sure Sidewinder kill.
He was a great tactician who, in one classic engagement, lured MiGs to attack Phantoms that were flying F-105 flight profiles. That was a very unpleasant and costly surprise for the MiGs.
Ahhh, yes. Operation Bolo. Imagine the surprise felt by the MiG pilots...
