I've only taken a look at the new threads about this FAA release for about a couple hours so far. But I wanted to make a new thread for less speculation and more analysis and such. To that end, here we go. I'll be posting information and details here shortly.

First up, to give everyone something to look at and while AA77.com finishes his very slow upload of the FAA Disk2 files.

The file "1 AEA 2869 disc 1 DCA CDRTM AAL-77 9-11-01.exe" under the "Pinnacle FOIA Materials" is a Lotus ScreenCam video of the CDR Replay software showing radar data from Reagan National. I performed a movie capture off the replay, time lapsed to speed it up slightly.
Here is it in AVI format zipped down to about 16MB

The following details I've have gathered for this radar replay.

Hi UT,

I found this on your bobcats the other day (p 3 of 6):

EDIT: And the narrative is on pages 5 & 6.

EDIT2: If I were to play "speculation hangman," bobcat == F-1_

Thanks dMole, so these are USAF planes.

I found Liden VOR but got nothing for MOL.

It appears this data has been available since early August. But it's new to me.
