At Sploid, Jesus Diaz shares some photos from the secret assembly line that built the SR-71 aircraft:
Built and designed in the 1960s after the A-12 Oxcart, the SR-71 Blackbird is still the fastest, most vanguardist air-breathing airplane in the history of aviation. These once classified photos reveal how Lockheed built both birds in secret, in California. They look taken at the Rebel base in Hoth.
H/T to Dave Owens for the link, and also a H/T to Jeff for linking to another photo story about how the aircraft were transported from Lockheed’s Skunk Works to Area 51.
