I am wondering if the flight simulator the captain had in his home could give a clue on what kind of manovers he was training for. We may find that he was training for fast ascensions to 45,000 feet to knock out the passengers, and that would make him the culprit. I am not sure if the software keeps track of it though, like a black box, but that is definitely something to look into. The next question is about motive, and I will never understand why people who want to commit suicide also feel they have to take 200+ lives with them.
