I have been thinking about the passengers and how they would deal with them. If they didn’t have weapons on board and wanted to quietly get to their destination, they were flying at a perfect time of night. The passengers would probably be asleep. Any deviation, the pilot could tell the passengers it was a minor navigation correction. Given the length of the flight, people on board might not notice
Staying primarily over water would keep the cell phones inactive till they reached land. Then they could more dramatically deal with the everyone on board.
I want to believe that our government is on this in a big way.

Climbing altitude and then diving 20K feet in a minute would certainly wake people up. It could be they intended to do what you said but there was a struggle of some sort.

People have told me they often use their cell phones when flying over the ocean. Or even their computers. So I would think it would be possible for one to make a call, send a text, or even send an email. Is this not so? I thought, when flying, cell phones can operate via satallite , not relying entirely on "towers."
