So much speculation; OK he was breathing, did not respond to ATC requests or the door, and made a control input. How does that all add up to the extraordinary speculative and hysterical attempt to find a mental health issue, and what business is it of ours (the public) until a proper investigation has been finished? Just as in the criminal justice system we have to wait until the committal and the trial before a verdict is announced, and to respect the man's and his family's right to this investigation and some privacy until the facts are there.
