A new post is up at
RetroMechanix.com presenting a Bell "XF-109" brochure and mock-up inspection program dating from February 1959:
This is the last article in our series on this ill-fated supersonic VTOL fighter; the profusely illustrated color brochure focuses exclusively on the Air Force variant, while the program provides an interesting overview of the mock-up inspection process and the state of Bell facilities in 1959. The article features 72 images reproducing both documents in full.
