Thank you 56P...Respect your opinion.
Still find it hard to believe... just from a pure human side.
It would take some type of major madman with major psycological problems to do what you suggest and whilst I admit Tsu may have had some issues to contend with...others also experience similar challenges in life and get on with life.. Whether they are a pilot or in some other just as noble profession..
If he was that psycologically disturbed...surely someone would have noticed and grounded him..(if that is the right terminology)...
I remain undecided.. to be honest.. but thank you nonetheless..
