and which ones would that be? so your saying hartmann got his 200+ kills just by "getting up close" ? or that Ivan Kozhendub did the same? if you didnt know, Ivan was considered the "deflection shot master" and I dont recall him ever saying he was a bad shot?
You can have computer sights of anything you like, but I think you have to go to the enemy on the shortest distance and knock him down from point-blank range. You'll get him from in close. At long distance, it's questionable.
I opened fire when the whole windshield was black with the enemy . . . at minimum range . . . it doesn't matter what your angle is to him or whether you are in a turn or any other maneuver.

I am not a good shot. Few of us are. To make up for this I hold my fire until I have a shot of less than 20 degrees deflection and until I'm within 300 yards. Good discipline on this score can make up for a great deal.

Go in close, and when you think you are too close, go in closer.
— Major Thomas B. 'Tommy' McGuire, USAAF.
Granted, Hartmann doesn't say he's a bad shot, but he does say get in close to where the difficulty of the shot is minimal. I seem to recall both Billy Bishop and Greg Boyington favoring similar tactics in their biographies but I haven't found the exact quotes yet. Again, several fighter pilots spent a lot of time practicing their shooting (hunting and sport shooting in their spare time, etc.), but there was definitely a school of aces who favored getting in close where deflection and range were minimal and blasting away.
