Some have suggested that the hijackers — if it was hijacked — might have donned oxygen masks and depressurized the plane, rendering the other occupants unconscious and then dead.

But wouldn’t that have set off an alarm and deployed the passengers’ masks, enabling at least one to send off a message?

The zig-zag course — a gambit to burn off fuel and lighten the 777 prior to landing on a short runway?

But wouldn’t flying low achieve the same effect — and evade radar at the same time?

Point-counterpoint — so much possible, so little certain.
