XB-70, world's most exotic aircraft, was designed in the 1950's as
high-altitude bomber flying three times the speed of sound. Due to
limited funds, only two built as research aircraft to study aerodynam-
ics, propulsion, and other aspects of large supersonic aircraft. Surviv-
ing XB-70 was retired to AF Museum, W-PAFB, Ohio, in 1969.
