Who Broke Mach 2?
Mach 2, the speed of twice the speed of sound, has been a significant milestone in the history of flight. Breaking the sound barrier was a significant achievement for pilots and aircraft designers alike. In this article, we will explore who was the first to break Mach 2.
Captain Albert Scott Crossfield: The First to Break Mach 2
On November 20, 1953, Captain Albert Scott Crossfield became the first person to fly an airplane at Mach 2, reaching a speed of 1,290 mph (Mach 2.005) in the Douglas D-558-II Skyrocket research aircraft. This historic flight took place at 50,000 feet altitude over the Pacific Ocean off the coast of California. Crossfield, a U.S. Air Force test pilot, was on a mission to test the capabilities of the Skyrocket, which was designed to explore the boundaries of high-speed flight.
Background on Mach 2
Mach 2 is a speed of approximately 1,290 mph (2,100 km/h), twice the speed of sound, which is about 670 mph (1,070 km/h). Breaking Mach 2 is a significant achievement because it requires the aircraft to be able to withstand the intense heat generated by friction with the air, as well as to maintain stability and control.
The Skyrocket’s Design
The Douglas D-558-II Skyrocket was a purpose-built research aircraft designed to investigate the physics of high-speed flight. The aircraft had a streamlined fuselage and a highly swept wing, which reduced drag and increased lift. The Skyrocket was powered by a rocket engine and a jet engine, providing a combined 10,000 pounds of thrust. The aircraft’s design and construction were tailored to withstand the extreme stresses and heat generated by flying at Mach 2.
Key Features of the Flight

Crossfield’s Career
Crossfield was a highly accomplished test pilot and engineer with a long and distinguished career. He was a World War II veteran and went on to fly experimental aircraft for the U.S. Navy and Air Force. In addition to his work with the Skyrocket, he also flew the X-15, a rocket-powered aircraft that reached speeds over Mach 4.
Conclusion
Breaking Mach 2 was a significant milestone in the history of aviation, and Captain Albert Scott Crossfield’s achievement will always be remembered as a major achievement. The development of high-speed aircraft and the exploration of the Mach 2 range have played a crucial role in our understanding of aerodynamics and the design of modern commercial and military aircraft. Today, we recognize Crossfield’s bravery and skill, as well as the remarkable engineering and design that went into the creation of the Skyrocket, as key factors in achieving this incredible feat.
