looking for website

I know that there is a website that will show you the up-to-date location of every airplane in the sky. I know there is one because I saw it on the news. They used it to represent how fast the skies emptied on 9\11. What is the address of this site? I think it would be neat to see just how many planes are in the air at any one given time

I'm not sure if this is the same exact thing that you saw on the news but try www.flytetrax.com. Its a pretty cool program... Shows you all the IFR flights (not sure if it shows VFR) their flight plans and everything. The only downside to this program is that you have to buy it. Not sure how much it is.. but they do have a 15 day free trial version that I used.
