A. Scott Crossfield served as a U.S. Navy fighter pilot and flight instructor in World War II but never saw combat action before he eventually joined the National Advisory Committee for Aeronautics (NACA) which would later be known as NASA. Crossfield's flying expertise, dedication, and technical acumen quickly landed him on the flight line as a test pilot. NACA recognized his passion and skill as an aviator as well as the ambition he carried that would be necessary for the high-stakes test flights of the NACA X-plane program.

Scott Crossfield, born in 1921, began his storied career with an education in aeronautics from the University of Washington. Crossfield's post-war career was distinguished by his missions in experimental jets. His pioneering spirit, meticulous nature and strong understanding of engineering earned him respect in the field and positioned him as a central figure in the supersonic era. His contributions, both as a pilot and in aeronautical research & development, were instrumental in the early days of the jet age.

On November 20, 1953, Crossfield achieved a historic milestone in aviation when he became the first pilot to fly at Mach 2. Piloting the DouglasD-558-2 Skyrocket, Crossfield reached speeds of 1,291 mph, marking a record-breaking achievement. The aircraft, powered by a rocket engine and launched from a B-52 Superfortress, was designed specifically for its supersonic research mission.
"Scott Crossfield became the fastest man alive when he piloted the Douglas D-558-2 Skyrocket to a speed of Mach 2, or more than 1,290 mph" - NASA Dryden Flight Research Center .
This momentous flight marked a historic leap forward in aerospace engineering. By achieving Mach 2, NACA successfully addressed extreme aerodynamics, control challenges, and thermal stress. Crossfield's flight demonstrated the feasibility of sustaining twice the speed of sound, a stepping stone leading to critical insights into supersonic travel and aircraft design. His contribution helped researchers and engineers understand the effects of high-speed flight on both pilot and machine, providing data essential for developing the aircraft that would come next. The Douglas D-558-2 Skyrocket itself was an essential asset in this era of experimentation, its design was optimized to break the sound barrier and collect flight data under high-stress conditions. NACA and Crossfield's first successful Mach 2 flight paved the way for faster and more advanced aircraft by proving that these limits could be surpassed safely.

During his long career, Scott Crossfield achieved a number of remarkable firsts.
First pilot to reach Mach 2: On November 20, 1953, Scott Crossfield became the first person to fly at twice the speed of sound (Mach 2), achieving a speed of over 1,290 mph in the Douglas D-558-2 Skyrocket. (NASA) First person to fly both supersonic jet and rocket-powered aircraft: Crossfield was the first to pilot both a jet and a rocket plane at supersonic speeds, furthering research into different types of high-speed propulsion. (NASA) First test pilot of the X-15 hypersonic rocket plane: Crossfield completed the first series of flights in the experimental X-15 aircraft, which was later used to set multiple altitude and speed records beyond Mach 5.

"Scott Crossfield's contributions are legendary; he was truly a pioneer who helped pave the way for future generations of pilots and engineers," said Neil Armstrong, the first astronaut to walk on the moon" ( NASA ).
In 1955, Crossfield left NACA and joined North American Aviation, where he was instrumental in the development and testing of the X-15 RocketPlane, which was capable of reaching speeds up to Mach 6. The X-15 program, one of the most ambitious aeronautical research projects of its time, was designed to study the effects of high-speed, high-altitude flight on both pilots and spacecraft. Crossfield became the first person to fly the X-15. This program transitioned from atmospheric flight to near-space mission - pushing pilots and engineers into new realms of high-altitude research. Crossfield's early flights on the X-15 provided foundational data that influenced NASA's design and development of spacecraft suitable for human space exploration.
