A co-incidence?

Well, I was previously dismissive of the dangerously unhinged pilot theory, especially when it was based on his support for Anwar Ibrahim.  But now I am not so sure.

The other thing is that the climb to higher than safe altitude always seemed very hard to explain.  As part of a plan by someone to disable the passengers, it does make some sense.  It would be a very twisted and self absorbed pilot who would do it as part of a final joy flight, though.  But if it was a hijacker, it's a bit of co-incidence that it was on a flight piloted by someone with (allegedly) a fair bit of trouble in his personal life.

Maybe the glowing digital cockpit screen in these aircraft need to flash a question to the crew before they take off  "You aren't feeling too depressed or unhappy today to fly?  Think of your passengers."   Who knows, that may be enough for some potentially suicidal pilots to reconsider.
