Well, since they haven't been in business before, I'd say it's not likely to be disguntled former employees. A DO has to have an ATP and three of the last six years as PIC in 121 or 135 ops. They can't find someone who meets those criteria and have to try to get a waiver? Oh, right, they're paying 600-700 a week. And you say since the DO is top management, to have to fire him, it must have been a big problem. The question is, where was the problem? Was the DO doing something wrong, or were the owners asking him to do something he didn't think was right? It could go either way.
I think the reason you see the negativity here is we're all wondering what they're smoking? They've been working on this for a while on a shoe string. Problem is, ATOS requires you to jump through the same hoops, whether you're a one plane start up or American Airlines. You know as soon as they start, AA and Continetal will have $39 fares to Louisiana out of DFW and IAH. After 30+ years doing this foolishness, I wish them luck. I sent a resume off 350 but it's been 20 years since I was near a Jetstream and I haven't heard anything back. I'm not holding my breath.
