It seems like I posted this already, but lately I have been doing so many things, I can hardly remember anything. :DAnyways, here is a link where you can read a bit about ATC and then click some links on the bottom of the page for ATC animations.Includes 9/11 animation too.http://www.edwardtufte.com/bboard/q-and-a-...00ji&topic_id=1

Thanks for the linkBrent Hebert
