Non-military pilot here, sorry for the intrusion. I did work at the Hawkworks though, and have to say the stories that we were secretly making stealth Blackhawks brought us much mirth. One of my coworkers included this picture in an email with the subject "Google Earth spot explained-DO NOT DISTRIBUTE!!!!"
Of course, the conspiracy people will view this denial as proof something was going on there.
Gotta go. Black stealth helicopters circling my position.
