The North American XB-70 is one of the most unusual looking aircraft in
aviation history, and only two were constructed. It was originally
designed as a Mach 3 high-altitude bomber, but was later used as a
research aircraft. This new book by John Campbell and Garry Pape gives a
short, detailed history of the XB-70, including production, flight
tests, and the fatal crash of Aircraft #2 in 1965. Aircraft #1 is now
at the U.S. Air Force Museum at Wright-Patterson AFB.
