Didn’t the captain report leveling off at their assigned altitude? I heard that’s not normal? Perhaps it was his way of crying out for help after being hijacked? I mean the flight doesn’t fit the narrative of pilot suicide. I’m thinking a controlled landing was attempted. Never said it was went successful. Strange how the only piece recovered is a flap. And it would make sense if it was retracted. And who’s to say hijackers didn’t make their way into the cockpit by starting a fire, then getting out of control? Sure sounds a lot more believable than the depressurized with pilot still somehow flying story
