I agree. Do pilots get to carry weapons, like a gun? If it was a suicide, I feel strongly that the pilot or co-pilot would have had to take out the other because the plane supposedly flew on for so long afterward. That would leave the FAs and passengers to figure it out. Passengers would likely be sleeping (although I would be shocked if each and every one was sleeping). I keep going back to the hidden axe. Don't FAs normally speak with the pilots at least periodically throughout a flight? I had never known about hidden axes on planes before now so it is possible the passengers didn't know about it either, but the FAs probably did. I just don't understand how a suicide could have occurred with no one talking some sense into him or overcoming him with force.
I've thought about something akin to a suicide bomber but I still don't understand why someone would continue for so long.
I am also curious about the possible psych issue. Depending on what was up, could there have been a psychotic break (think of that recent situation with the mom driving her kids around and eventually trying to drive them into the ocean)? That would account for what appears like illogical choices to us. You would think he would have been acting up though beforehand. Even in the case I just mentioned, the sister noticed and called LE.
IDK, no theory seems to account for all the weirdness. Hopefully the discovery will answer all the questions but I totally agree with whoever mentioned that even with a discovery and explanation, it will probably not be universally accepted.
