The F-22 is revolutionary with it's ability to supercruise. Combat experience or not, that makes the list.
I don't agree with the Camel being on the list... I don't recall it being anything near dominating in WWI. It was, however, manufacturable. I see it's presence on par with putting a Soviet T-34 on the list of best tanks. It deserves to be there, but it's manufacturability was it's greatest asset. It seems there were other WWI aircraft that were far better.
The F-4 is another oddity on the list. The only thing remarkable about it was that it was used by all branches of the U.S. millitary. It did everything OK, but nothing great. It's weapons system was innadequate given the poor reliability of the missiles in high temperature/hummidity environments at the time and the fact that it didn't have a canon. Hell... I'd rank the A-4 skyraider above the F-4.
I do think the F-15C should be ranked 1st though. Maybe it could slip to #2 if someone were to actually shoot one down.
