William Barton Bridgeman was an American test pilot who broke aviation records while working for the Douglas Aircraft Company, testing experimental aircraft. In July 1951, the United States Navy announced the D-558-II Skyrocket piloted by Bridgeman had "attained the highest speed and altitude ever recorded by a piloted plane". On August 15 of the same year, he set a world record with a speed of Mach 1.88 and an unofficial record height of 79,494 feet (24,230 m).
