of sound. Crossfield learned to fly with the Navy during World War II
and became an aeronautical research pilot with NACA (National Advisory Committee for Aeronautics) in 1950, flying the X-1 as well as the Douglas Skyrocket (D558-II) and other experimental jets. He was the chief engineering test

first powered flight of the X-15 in 1959 reached
Mach 2.11 and an altitude of 15,953 meters. Crossfield died in a plane crash
