The USAF's first jet-powered bomber capable of reaching Mach 2.0, the Convair B-58 Hustler carried a crew of three and a nuclear payload. A complex aircraft, the B-58 suffered teething problems during development and became infamous for its maintenance requirements. It also compiled a dubious safety record: out of 116 Hustlers, 26 were lost in accidents. Nevertheless, the B-58's career spanned nearly a decade between 1960-70. It might have continued even longer, but Secretary of Defense Robert McNamara believed the aircraft, which was designed for high-speed, high-altitude tactical approach, was vulnerable to air-to-air missile attack. Its replacement the F-111A Aardvark would be designed to perform a low approach attack. Originally printed by the U.S. Air Force, this B-58A flight operating manual taught pilots everything they needed to know before entering the cockpit. Originally classified Restricted , this manual was declassified long ago and is here reprinted in book form.
