Thank you Rockhound and I note your head bashing. However the facts are that one could equally say that there was no earthly reason for a 41 year old (whom many would say was also young) in good health (as an active pilot) and at the prime of a flying careeer, to commit suicide.
I thought the Captain had a distinguished flying career in both the military and in the airlines. If it was blemished, I would ask just how serious those blemishes really were, and how they compared with other career pilots. If those blemishes were serious enough to justify suicide then why was he, and all the other pilots with blemishes, not stopped from flying.
It always comes back to this same (head-bashing) point that one pilot has every possible bit of circumstance argued against him, while the other pilot is automatically free from the enquiry that would show up the very evidence you seek.
