Trevor Paglen has written a fun book, peeking discreetly into the "black world" of secret military projects by reproducing the patches worn by workers on the projects. The patches are surprisingly artful and whimsical, often invoking wizards and dragons to heighten the aura of mystery. Here is a typical example:
In this case, the motto has proven accurate, as Paglen was unable to figure out what unit was associated with the patch. Probably has nothing to do with pornographic movies, but you never know. The staging areas for many of the secret operations are in the Southwest U.S., including the Area 51/Groom Lake facility where conspiracy theorists are convinced that the government is harboring alien technology from the crash at Roswell. Which, as you might imagine, makes for great source material for the patches. This one comes from the 509th Bomb Wing, in charge of the B-2 Stealth Bomber -- the 509th used to be based in Roswell, although it has now moved to Missouri.
"Gustatus Similis Pullus" translates from Latin as "Tastes Like Chicken." Get it? "To Serve Man?" If not, there is a subtle knife and fork on the patch just to drive home the message. Other times, the emphasis on secrecy is more overt. This patch is from the 22nd Military Airlift Squadron, which would fly C-5's to deliver classified aircraft from aerospace plants in Southern California to testing facilities around the country.
"NOYFB," in case you were wondering, stands for "None of your fucking business."
