On the recent airing of the Flight 93 documentary....a pilot (I believe) specifically said the terrorists did not know how to work the GPS on the plane, and didn't know how to turn off the alarm when the auto pilot is turned off....

That was an interesting documentary.

It would take many hours of training to learn how to operate the FMS in any airliner.

Turning off the alarm is simple once one knows. It's a simple push of a button if one understands the system.

Yes it was. I learned a lot. I had no idea how tricky/different it would be to fly a commerical plane than the smaller planes. Thanks for your added info.
