It does appear the National Geospatial Intelligence Agency will be terminating public access to many of it's available aeronautical references on 1 October, 2007. Documents currently available have a start date of 30 August, 2007, so these are probably the last of these we'll see...
U.S. Flight Information File in several formats (raw data):
https://164.214.2.62/products/usfif/index.cfm
Planning/Enroute Supplements:
https://164.214.2.62/products/usfif/enroute.cfm
Certain Enroute Charts, including those for AP1B:

Military versions of terminal procedures & diagrams:

If you enjoy military aircraft monitoring ("milair"), especially in the 225-400 MHz band, or, if you are just a hard core aviation buff, I'd suggest downloading at least from the Planning/Enroute supplements:
AP1B, the FIH, U.S. IFR and U.S. VFR supplements and also possibly GP (general planning) and others in the AP1 series. Refuelling buffs will also want the chart sets for AP1B. These are all large documents, though the NGA server is notoriously quick.
We had filed official objections to removal of these documents from public access during the comment period last year. They went unanswered and were apparently over ruled, along with many other objections.
It will be interesting to see if other online references such as www.airnav.com will be able to maintain listings of UHF paired frequencies at air traffic control facilities.
It is unknown if the above publications will still be available for purchase in hard copy formats from the FAA after October 1st, but you may want to consider purchasing hard copies now, as well.
The official FAA data file - "ATA100" - will probably remain available for download from various online sources, but this is NOT the same data set as the above documents.
Thus ends an era of data, its been fun. Please standby while we return you to dark ages of milair monitoring... Where's that "search" button...
