George Welch … Pearl Harbor hero …
On 12 October 1954, one of America’s most remarkable fighter pilots and test pilots was killed pushing a new airplane to its limits.
George S. Welch was North American Aviation’s chief engineering test pilot when he took F-100A Super Sabre 52-5764 into a Mach 1.55 dive over California’s Mojave Desert. The test called for a hard 7.3-G pullout to verify the fighter’s structural limits. Instead, the aircraft encountered inertial roll coupling, departed controlled flight, and broke apart. Welch survived the initial breakup and ejection, but died while being flown to the hospital at Edwards Air Force Base.
It was a tragic end to a career that had already spanned two very different eras of aviation.
Welch first became famous on December 7, 1941. He and fellow 2nd Lt. Kenneth Taylor raced to Haleiwa Field, climbed into their P-40s, and took off against the Japanese attack on Oahu. Welch was credited with four aerial victories that morning and later received the Distinguished Service Cross. He would go on to fly P-39 Airacobras and P-38 Lightnings in the Southwest Pacific, ultimately receiving credit for 16 enemy aircraft destroyed before malaria ended his combat tour.
In 1944, Welch left active military service and joined North American Aviation as a test pilot. There he helped move American fighter aviation from piston engines into the jet age. He made the first flight of the XP-86, prototype of the F-86 Sabre, on October 1, 1947, and later made first flights in several other North American fighters.
Welch also became part of one of aviation history’s enduring debates. Some witnesses later claimed that during early XP-86 testing he exceeded Mach 1 before Chuck Yeager’s historic Bell X-1 flight on October 14, 1947. NASA’s historical review, however, notes that no surviving test data proves the claim. Official records show Welch reaching Mach .93 in November 1947, while the XP-86 was conclusively flown supersonically after receiving a more powerful engine in April 1948.
By 1953, Welch was testing another revolutionary North American fighter, the F-100 Super Sabre, the Air Force’s first operational fighter capable of sustained supersonic flight. An Air Force publication from 1954 credited Welch as the first man to fly the F-100 supersonically in level flight.
The airplane that killed him also taught engineers an important lesson. Welch’s accident helped focus attention on the dangerous phenomenon of inertial roll coupling in early supersonic aircraft. NACA test pilot Scott Crossfield subsequently spent months flying F-100As with different vertical fins to study the problem, contributing to changes that improved the Super Sabre’s stability.
George Welch’s career began in combat over Pearl Harbor and ended at the edge of the supersonic frontier. He was just 36 years old when he died.
