Was the sound barrier broken by accident two years before Chuck Yeager?
In short: For years, pilots feared a lethal phenomenon known as the sound barrier, which caused aircraft to lose control and dive at high speeds. While Chuck Yeager is credited with the first supersonic flight in 1947, evidence suggests a German pilot may have accidentally achieved this feat during World War II.
In the 1930s and 1940s, pilots flying above 600 km/h faced a terrifying issue called compressibility. As planes approached the speed of sound, or Mach 1, their controls would lock, and the nose would pitch down into a fatal dive. This was a major danger for high-performance aircraft like the Lockheed P-38 Lightning, which claimed the life of test pilot Ralph Virden in 1941 when his tail structure failed during a high-speed dive.
On October 14, 1947, U.S. Army Air Force Captain Chuck Yeager officially became the first human to exceed the speed of sound in the Bell X-1 rocket plane over the Mojave Desert. This milestone earned him the Collier Trophy. However, the history of this achievement is complicated by reports that a German pilot may have inadvertently broken the barrier two years earlier.
