Here is the thing, what are the odds that the captain was going to die. What are the odds the terrorist would of known it and gotten on to this flight. Furthermore what were the odds a terrorist is going to Mexico. Isn't there enough terror in Mexico?
I think the guy made a good call, again anyone can deviate from the fars in the event the emergency calls for it. I don't know what the weather was like but I am certain an extra set of ears and eyes was helpful even to handle the radio calls.
The thing I want to know is this, was the captain an MEI. How'd that be in the log book for instruction received.
