The aircraft in this photo collided with a civilian registered F-104N flown by famous test pilot Joe Walker, who tragically died in the accident during a photo flight.

The second XB-70A (62-207) was built with an added 5 degrees of dihedral on the wings as suggested by the NASA Ames Research Center, Moffett Field, CA, wind-tunnel studies. The first XB-70 had been found to have poor directional stability above Mach 2.5, and only made a single flight above Mach 3 but the second XB-70, that made its first flight on Jul. 17, 1965, achieved Mach 3 for the first time on Jan. 3, 1966 and successfully completed a total of nine Mach 3 flights by June on the same year.
A joint agreement signed between NASA and the Air Force planned to use the second XB-70A prototype for high-speed research flights in support of the American supersonic transport (SST) program.
