Latest reports I read, Luibitz was been treated for an eye condition that he believed would end his career and end in blindness, which makes his decision acceptable- not !
Just looking at the news with his smiling picture by the bridge, maybe it would have been better for everyone involved if he had decided to jump from it there and then.
I don't understand how anyone could do this, if he was suicidal why not throw yourself out of a tall building, which would have resulted in the same result, instead of taking another 150 people with him, many were children and he would have known that.
I guess a rational person can not...
