Today in History – November 27, 1957 – Sun Run RF-101C aircraft transcontinental speed record

27 November 1957: “Four U.S. Air Force pilots of the 363rd Tactical Reconnaissance Wing successfully completed Operation Sun Run by establishing three new transcontinental speed records in a McDonnell RF-101C aircraft. The record-breaking mission showcased the speed and range of the RF-101C, an improved version of the first supersonic photo-reconnaissance aircraft, the RF-101A.

“Operation Sun Run called for six RF-101C aircraft — two to fly round-trip from Los Angeles to New York and back again, two for the one-way flight from Los Angeles to New York, and two for backups if problems arose with the four primary aircraft. The undertaking required massive coordination of aircraft crews and radar and weather stations from coast to coast.

Sebring (18th TRS commanding officer, Operation Sun Run operations officer), Lt. Col. William H. Nelson (9th AF, Operation Sun Run programs officer), Capt. Robert E. Burkhart, Capt. Robert M. Sweet, Lt. Gustav B. Klatt. (U.S. Air Force photo)
“Six pilots of the 17th and 18th Tactical Reconnaissance Squadrons of the 363rd Tactical Reconnaissance Wing were chosen for Operation Sun Run. Each prepared for the round-trip flight, since they would not know which flight they were assigned until a few days before the operation. All six pilots had extensive experience in photo reconnaissance aircraft, although the RF-101 was relatively new to Tactical Air Command.

“The success of Operation Sun Run also depended on the performance of the newly available KC-135 Stratotanker, the USAF’s first jet tanker. The KC-135’s speed allowed the RF-101s to refuel at an altitude of 35,000 feet and a speed of Mach 0.8. Crews from Strategic Air Command and Air Force Research and Development Command prepared for the 26 refuelings the Operation Sun Run RF-101Cs would require.

“At 6:59 a.m., 27 November 1957, Capt. Ray Schrecengost took off from Ontario International Airport near Los Angeles on the first RF-101C round-trip flight of Operation Sun Run. Next into the air were Capt. Robert Kilpatrick on his one-way flight and Capt. Donald Hawkins, flying back-up. Capt. Hawkins followed until the first refueling was complete, and then flew to March Air Force Base, Calif. At 7:50 a.m., Capt. Robert Sweet took off on the second round-trip flight. Lt. Gustav Klatt followed, beginning his one-way trip. Their backup, Capt. Robert Burkhart, also flew to March Air Force Base after the first successful refueling.

“All four RF-101C pilots easily surpassed the previous speed records and established new ones. The new Los Angeles to New York record was established by Lt. Klatt, at 3 hours, 7 minutes and 43.63 seconds. Capt. Sweet set the round-trip record, at a time of 6 hours, 46 minutes and 36.21 seconds, and the New York to Los Angeles record, at a time of 3 hours, 36 minutes and 32.33 seconds.”
