I’m still going with Muzzie co-pilot kills pilot, angles plane down and nose dives it at 600+ MPH into sea. Whatever held together went to the bottom. Whatever didn’t probably was water logged and went to the bottom.
I’ve leaned toward this scenario from the gitgo. Co-pilot could turn off the transponder and never have to breach the door. I wonder what the optimum entry angle is to create the minimum debris field? He also could fully retard throttle on one engine, do an aileron roll into a half split-s until perpendicular to ocean and accelerate. Most have fallen out of their seats and those that haven’t are too disoriented to respond.
Why? What’s the point?
Terrorists’ actions are supposed to be terrorizing, not leave us scratching our heads. Why crash over water? What did that prove?
Stolen plane for perhaps a real terrorist attack? Plausible.
