Developed from the Lockheed A-12 and YF-12A aircraft, the first flight of the SR-71 Mach 3 + spy plane took place on Dec. 22, 1964, and the first aircraft to enter service was delivered to the 4200th (later 9th) Strategic Reconnaissance Wing at Beale Air Force Base, Calif., in January 1966.
Throughout its nearly 24-year career, the SR-71 remained the world’s fastest and highest-flying operational aircraft. From 80,000 feet, it could survey 100,000 square miles of Earth’s surface per hour.
According to the book Velocity Speed With Direction – The Professional Career of Gen. Jerome F. O’Malley by Aloysius G Casey and Patrick A Casey, the Lead Sled was an unaffectionate name.
The SR-71 was nicknamed the Sled* by a few people after Jerry O’Malley and Ed Payne dropped 60,000 feet over Vietnam in 1968.
O’Malley and Payne have the distinction of logging the second combat sortie for their Blackbird. (They also have the honor of having the first successful combat sortie.) After refueling, they coasted near Saigon and headed north to cross the DMZ into North Vietnam. Near the end of their run, a message was received to abort the remainder of the mission based on confusion in the command chain on exactly what President Johnson meant in a speech he made that day about restricting “strike” aircraft flights north of the 19th Parallel over Vietnam.
As O’Malley eased back on the throttles, both engines rumbled in a compression stall and immediately flamed out! Jerry pushed the nose down to get to the denser air needed for an air start of the big engines. They decided that if they could not achieve an air start at 23,000 feet, they would call it “MAYDAY” and bail out at 14,000 feet. Attempts at 40,000 and 30,000 feet failed, and Ed Payne noted 26,000 feet. As he made ready for the call, he called out, “MAY. . .” the aircraft shook, and O’Malley said one engine had started. By the time they made 20,000 feet, Jerry had both engines “turning and burning.”
Jerry headed south and prepared for the descent. Jerry discussed at length the data he wanted Ed to record as they flew the normal profile back to the home base. When it came time to ease back on the throttles, the engines spooled down normally, and they landed back at Kadena without further incident.
The double-engine flameout was the precursor to several similar incidents that followed over Laos and served to reinforce the undesired nickname of Lead Sled …. back at the SAC Reconnaissance Center.
Later, as time went on, the term sled was used in an affectionate way.
*According to The Complete Book of the SR-71 Blackbird by Richard H. Graham, the Blackbird was dubbed ‘Sled’ because the U-2 pilots didn’t like calling the SR-71 by its proper nickname, so they came up with a derogatory name of their own, calling it the ‘Sled.’
