I get a shrug every time I ask anyone who might have an interesting answer to this question: “Why is there so much numeric symbolism in the visual imagery of the USAF (especially “black” projects)?”
This photograph clearly depicts five crew members and two vehicles, possible a coded boast they are at Area 52 of the Groom Lake facility in Nevada. It seems a little far-fetched until you see some of the insignia made visible by FOIA requests.
In fact, it’s public knowledge that OXCART did operate out of Area 51.
