Good evening!
Having just screened this picture, I wanted to complete the USAF serial and got stuck somewhere nowhere, because I just could not properly identify this a/c:
http://www.flugzeugbilder.de/show.php?id=1209820
The uploader entered it as a EC-137D (it being some sort of C-137 was obvious as well to me ...), apparently operated by the AFSOC from Hurlburt Field. The Scramble USAF database lists an EC-137D 88-6008, but this entry is marked as uncertain.
So, if anyone could provide us with more information, that would be VERY welcome.
Cheers
JOEL
