Just Say NO.
It is tough to say NO to your boss. Beyond the Polish tragedy, I hope we can all learn something.
I think that the one thing that must be understood in the pilot/boss relationship is that the PILOT is the boss of the plane.
So, when the boss says: DO IT. YOU SAY: NOPE, DO YOU WANT TO FLY IT? Then here are the KEYS. (smaller planes usually have keys...for the ignition system...bigger planes sometimes have keys to the door, but don't need them to ''start'' the plane)
I would make it a law that if a pilot is fired for saying NO, then they get six months severence pay.
