I think he means a real one, although I could be wrong.

Matt's correct, the real one based here in Corpus Christi. I tried a C-421 sim package once (long ago, I think Flight1 has it) and it was okay but nothing special about it.

Yep, we usually go through multiple beta versions - each version fixes things the testers have reported previously, so Beta 1 is just the first version we give to the testers. They report back, then we issue Beta 2 and so on until we're satisfied it's ready for release. We then issue a "Release Candidate" or RC version and if everyone signs off on it, that becomes the "Gold" code and is what gets released for sale.

I recently beta tested a Flight Simulator X addon product, and that had a total of four beta versions.
