Apologies and thanks to Orthos, and you.
"HOW can a plane be up there after it crashed?"
Simple question, huh?
Now, the software they are using is something called "Flight Explorer".
It displays all air traffic and the flights info, for an area.
The first thing that comes to mind is that Flight Explorer does time delay their data.
Says so right on their site. But it is in the 15 minute range, and never more than 30 minutes.
But this MSNBC footage has got to be from later than that.
* First Tower has already fallen.
* Both planes already hit. (they say)
* All planes have been grounded, nation-wide, and...
* Look at the screen. The whole New York/Boston air traffic area is damned near empty!
It's got to be close to an hour after the plane hit. It might be possible to compare this to some known time line and establish it more closely.
So...
