United planes were told to secure cockpit

I wanna know if any of the planes got wind of the fact that WTC the North Tower was struck?

If CELL phones were being used, I would imagine other planes heard. I would expect a huge fight if this was the case.

Just to add, I also find it almost unbelievable that the planes didn't get off a signal. I mean bank tellers frightened to death usually can get off an alarm.
