he F-89 Scorpion was the first multi-seat, all-weather jet interceptor in the U.S. Air Force. It also became the first aircraft ever equipped with a nuclear air-to-air weapon ¿ the 1.5 kiloton Genie missile. The F-89 made its debut in 1948, joined the Air Force in 1950, and then served as the mainstay of Air Defense Command for 17 years. Over 1,000 F-89s were produced, including 350 of the ¿J¿ model equipped with pylons to carry the Genie. (One F-89 did fire the missile as part of Operation Plumbob in 1957.) Originally printed by Northrop and the USAF, this F-89 Flight Operating Manual taught pilots everything they needed to know before entering the cockpit. Classified ¿Restricted¿, the manual was recently declassified and is here reprinted in book form. This affordable facsimile has been reformatted and color images appear in black and white. Care has been taken however to preserve the integrity of the text.
