Sorry about the delay in responding. Things have been kind of busy.
Regarding 9/11 and security issues and dispatch in general.
On 9/11 in some cases individual flight dispatchers and airlines took action before the FAA regarding grounding flights. Also, when flights were ordered grounded, flight dispatchers worked with the crews to put the flights in the best possible place under the circumstances. They were a valuable resource.
In my own experience as a flight dispatcher, I had several occasions where a flight had a bomb threat during flight or had hijacking situations. In all cases the decision as to where the flight should go or what should be done was made working with flight dispatcher and the crew with the best information possible and with management input as well. We also had effective communications with the crew during those situations.
