Strikehawk is correct about NAS Cecil Field being on the top of my list for FSX sceneries that I hope get updated for FSX. John Stinstrom did a magnificent job on the FS9 version (in my opinion). He even did his utmost best to recreate the barracks near the chow hall, along with many other buildings that were on base at the time. 90% or more of those buildings are all gone now, since the closure of NAS Cecil Field, back in the late 90s. The City of Jacksonville took it over. So a recreation of Cecil for FSX would be awesome!
Also, I know that Jim Cook created a version of Pax River for FSX, but am holding out for a more detailed one. And I've also hoped that perhaps NAS Agana, Guam would be done some day.... I have a few pictures of VQ-1's hangar, plus there are some pictures available on the net of other buildings at Agana.
As for Cecil, I have quite a few pictures of the base. Although I was at Patuxent River from 73-76, I don't have any pictures of the hangars. Wish I did!
