The de Havilland Vampire, which made its maiden flight in September 1943, was the first Royal Air Force fighter with a top speed exceeding 500 mph (805 km/h). Although it never saw service during World War II—it was still in development at the war’s end—it is credited with a number of aviation firsts, including becoming the first jet to take off from and land on an aircraft carrier and to fly across the Atlantic. Which major Western powers were the only ones not to use this type of aircraft? Discuss
