Yes, he forgot something very important.
Aviation has fast become an occupation where you do and go where you are told. The pilots job really is to stop the thing crashing between dep and dest. I am sorry to say an "Airline pilot" is not much more than a robot these days. Computers can do our jobs.
Attempting a beat up is foolish in the extreme. It is just not worth it as recent events have proved. Who was he trying to impress? Certainly didn't impress me. If he needs to get his "rocks off" by trying to show how "good" he is, then may I suggest he do it in the simulator as that is the place to monkey around.
He also forgot another thing. The bigger you are, the harder you fall. Justice had to be shown to be done and was done it seems.
