I will add one that actually happen at LKPR. In CzechAirlines some of the Boing pilots doesn´t rly like the Airbus pilots and oposite. Once where there was alot of planes waiting for departure making beeline the pilots in the front plane that was an airbus have some problems, and they were holding all the other planes behind as they can´t departure saying that they have some problem with the "computers". Then they answers the tower question and this happens.Airbus pilot: Tower we aren´t ready for departure we still have problems with the computer.Than the Boeing pilot come in.Boeing pilot: You know what? Press triangle square L2 and fly to the ###### hole with your playstation.Unfortunately the Airbus pilot take it too serious and complain to him so the Boieng pilot got some recourse from the authorities. :(
