The thing about the Baron is that he was by all accounts a fine young man, but mostly what makes him a legend is simply the kill count: 80 kills is a huge number, and only a few men have ever bested it, although some that did (such as Eric Hartmann) did so by a very large amount. But even some of the best fighter pilots who ever put on a helmet, guys like Saburo Sakai, Gabby Gabreski, Robin Olds...never got 80 kills.
Well, he excelled in the earliest days of the sport, so to speak.
All of the tactics were experimental at best. Later pilots stood on the shoulders of these guys, I would suppose.
