Interesting theory, but was there chaos on board the 9-11 jets?
Not in my opinion.....

And what if the passengers of the other 4-thousand odd planes in the
air at the time learned of the hijackings and suicide crashings while
they were still in the air?

You don't think there'd be some freeky stuff happening on some of
those planes if they knew?

When all those planes were forced to land, I bet they were told
something like "ladies and gentlemen, this is the Captain speaking.
We've got a small problem with (you-name-it) and so as a precaution
we're going to make an unscheduled landing. Nothing to fear or be
worried about. Just sit tight and relax and we should be on our way
again shortly."

Heck, the flight crew never tells you the straight goods regarding the
status of your own flight (like delays, ETA, connections, etc) just to
keep you calm and not a pain in their side.

The less you know about anything happening in real time, the better.
Whether it's about the flight you're on, the goings-on in the cabin,
or the outside world in general.
