Test pilot. Space career. USAF Test Pilot. Selection. 1958 MISS Group. Missions. None. Alvin Swauger White (December 9, 1918 – April 29, 2006) was an American test pilot and mechanical engineer. He flew the maiden flights of both XB-70 Valkyrie aircraft, the first 2,000 mph (3,200 km/h) flight, and all subsequent Mach 3 exploration flights.
The F-104 was estimated to be 70 ft (20 m) to the side of, and 10 ft (3 m) below, the fuselage of the XB-70. The report concluded that from that position, without appropriate sight cues, Walker was unable to properly perceive his motion relative to the Valkyrie, leading to his aircraft drifting into contact with the XB-70's wing.

The sonic boom was not thought to be a serious issue due to the high altitudes at which the planes flew, but experiments in the mid-1960s such as the controversial Oklahoma City sonic boom tests and studies of the USAF's North American XB-70 Valkyrie proved otherwise (see Sonic boom § Abatement). By 1964, whether civilian supersonic aircraft ...
