ASA never flew ATR-72-500s. They did fly ATR-72-212s. I would think someone who claims they flew it would know that and know there's a pretty significant difference. But then you make a lot of wild claims, and judging by the comments here you have a serious credibility problem.

I've never met you, so I can't say for sure, but I've read a lot of your stories here, and always come away thinking "this guy is a management stooge whose full of crap. Another bootstrapper who thinks his crap doesn't stink". Read the room man. If 50 guys are telling you you're out in left field, maybe they're not the ones who are wrong.
