From March 1960 to July 1961, the 43rd operated a combat-crew training school for B-58 aircrews, and, from July 1962 until late 1969 it served as one of two SAC B-58 wings with a strategic-bombardment mission. During the 1960s the wing established world-flight speed records in the B-58, beginning on 12 January 1961, when it set six international speed and payload records on a single flight, five of which were held by the Soviet Union. Three of these records lasted only two days, when they were broken by another 43rd Hustler, which flew over a 1,000 km closed course with a payload of 2,000 kg at an average speed of 1284.73 mph, simultaneously breaking the 1,000 kg and no payload records. The crew on the second flight was awarded the Thompson Trophy.
