Water under the bridge. It's not like you could get in trouble at this point anyway. Just make sure you have your facts straight before you go bashing other pilot groups for an arbitrated decision and then backpedal using fatal accidents as some sort of heinous barometer that says they are worse than someone else.
As already stated, I have never landed flaps 0. No one would do that "just because." Obviously it has to be an abnormal/flaps fail situation to land at flaps 0. I don't know how it is now, but when I was at 9E, in the flaps 0 profile, the very last portion of the profile was at 60 kts "CA - I have control. FO - You have control. If FO landing" So that shows that it is ok in an abnormal situation for a FO to land at flaps 0, and not just a Captain-only landing. But again, I never landed flaps 0. Just make sure you know the profile before you bash someone for something they never did to begin with.

No, what I said was nearly all of those regional airlines cease to exist after a fatal passenger death crash. Regions/Corporate Air, Air Midwest, Colgan, Chalks Ocean Airways. There is no denying that after the Colgan crash, the Colgan name had to go. Ocean Chalk airways was the oldest airline among the regionals to be in service but once the fatal crash happened in 2005, that airline was done for and shut down. It's not a matter of being worse than someone else, it's just looking at past history to see what happens to regional airlines when they have a big fatal passenger crash. Either the name disappears/changes, or the airline itself ceases to exist. This *fact* should have been accounted for in "career expectations." But anyway, like you said, what's done is done and is all water under the bridge.
