I'd rather caution on the side of extremely gullible than calling him a liar. I'd like to hear what he has to say about it and if he has any old documentation to share. I want to believe really badly, that would be so cool if a 95 year old world war 2 vet was playing aces high.
Sadly we've been down this road before. Only one has proven to be the real deal in terms of being a combat pilot. He never claimed to be an Ace though. That's what I can't figure out. If you are that bent on making it up. Don't claim to be someone that can easily be tracked down. So far in my 15 years of cartoon piloting, I've met a 109 Ace, and a P38 Ace. Both disappeared naturally when I started asking questions in good faith as I thought it was amazing. We also had the infamous Ken Jr and Ken Sr of 80+ missions with the 91st BG, own our own B17 and the fake memorial for Ken Sr after he 'died'. That was all BS too. Not to mention that great Scorpion King.
Only Earl turned out to be the Silver Star winning, DFC winning, P39/ Jug driver from the 350th FG in the MTO. He's still living but didn't make the transition from AW to AH.
If this guy is legit, then there should be no reason it can't be backed up, and if so, honored by the rest of us. As is, there is nothing out there and the 'facts' he's shared aren't even close to accurate.
