I think most people in this forum are under the false impresson that the Captain was fired.
No, he was NOT fired but demoted from a Captain on expatriate terms to a Co-pilot on local terms. (Essentially saying please leave) He chose to leave the airline on his own. I understand that he is working as a Copilot now and expected to make 340 command soon.
The tragical part is that he is a very good operator and a very cool headed and decent guy, a kind of person who is least likely to make this kind of mistake. The whole incident is an invaluable lesson to all of us in aviation.
