Yes, you're right but hence the quotes, those P51 pilots would probably say otherwise.

One of the things which stands out is on a year to year basis, 39, 40, 41, 41, 1/2 of 42, The German air Force were the masters of the skies! But when the industrial might of the U.S. begin to have a direct beariong ont he outcome of the war, its easy to see who won and why.
I don't have any doubt that the American pilots were by far, the best trained during that time in history! However, again, the Israel air Force proved how well their pilots were trained during the 67 war.
I think the one big advantage for any good fighter pilot is his ability to see before the attacker sees him! In almost every account of "Gabby's" kills, except in one instance, he saw the Krauts or Italian pilots before they knew he was anywhere around.
I think Robert Olds proved that also.
The Korean conflict was pretty much a "push", although we did manage to down more migs than they downed us.
Of course if you read the North Korean version of what happened, we lost by a large number.
I have talked to actual F-86 and F-84 pilots who fought those "Kooks" and all they would do is 5 or 6 would start a "merry go around" and when one of our guys when in to get a kill, he had someone on his "6". As soon as they, the Americans learned to attack on the "cardinal" points of the compass, that put a stop to that nonsense!
