Despite the tenuous link with the thread title, I was on another site and watched a video that ended with this video as a suggested viewing.
One of my all-time favourite documentaries, this first episode of the "Connections" with James Burke called `"The Trigger Effect" starts the series with the host in the WTC plaza. He rides up to the roof to talk about how civilization hangs on by a thread...
The episode then uses the East Coast black-out to show just how. Now for the clincher. Air-traffic control is one of the examples and, you guessed it, the incoming flight provided during the crisis was .... wait for it.... 9-11, of course. You can see it on the screen at precisely 9 minutes and 11 seconds into the video...
