This defiantly warranted its own thread, and mods, please let this thread fly here for a bit, as OPs post was based on requests to move the above account out of a flame-ridden thread.

There was a feature done by Tom Brokow during NBC coverage of the 2010 Winter Olympics about all of the TATL flights diverted to Gander, Newfoundland on 9/11. It does a great job capturing how a small town dealt with the influx of dozens of wide-body jets for several days. That feature can be found here..

If you are fascinated by these stories there is a documentary called Grounded on 9/11
It's a History Channel piece on how ATC shut down US airspace, and also addresses the Gander story in detail. IMO it is the best documentary related to aviation I have ever seen. Unfortunately it is not available on the web, but if these sorts of incidents fascinate you, it might be worth the buy. It will surely be shown in September when the History Channel runs all of its 9/11 documentaries.
