Bomb issue
I would think that a bomb would leave a lot of surface debris, and a fireball that many would have been reporting on by now.
It was a clear night with other planes in the sky.
A fist full of plastic would have to be of very good quality and placed pretty well.
Aloha landed with 20 feet of the fuselage blown away from fatigue failure. I know, not the same differential.
Not saying it isn't possible.
Again....no one taking credit it for it ....yet.
