You're out of your depth. BUF and LEX are apples and oranges.
No excuse for the behavior in BUF. But LEX was a different animal, and dismissing the crew as clowns throws away the very real safety gains to be made from the lessons of that accident.
I flew RJ's into Lexington at a previous carrier. I trained with/knew many Comair guys. Trust me, if a mistake like LEX can happen to Comair it can happen to anyone.
And firing up the wrong aircraft? You think they did that by accident? Tail swaps happen all the time.
I'll spare you any chest beating but trust me, my employers know my opinions all too well - a function of my position, you see....
