My favorite comic book in the 60's was Enemy Ace, along with Sergeant Rock and The Haunted Tank, etc... In 1998, I started flying a WW1 air combat sim called Red Baron II, then later Red Baron 3-D, on-line and most of the other sim-pilots took historical WW1 pilot names, but there were three of us who went with fictional ones, Von Hammer, Bruno Stachel (The Blue Max), and Steve Savage (The Balloon Buster). There was also a dedicated Red Baron Forum from Sierra, the makers, so I was Hans von Hammer there as well, and have been ever since.. We actually have some real-world events in which we all get together for big "Red Baron Party", and no one can remember anyone's names, so we're all known by our screen personas all weekend..
It even carried over into my WW2 re-enactments, my character's name is Von Hammer during those events too. I have a complete "biography" of my character in my Soldbuch, hometown, Mother, father, siblings, relatives, all the stuff that would have been in a real German Soldbuch...
My avatar changes from time to time, but right now, it's a pic of me modeling the P-82 Twin Mustang..
