In 1976, it was a different time. The Cold War with the Soviet Union was in full swing and Americans were standing in line to buy gas.
That year was also the country’s bicentennial birthday. To celebrate, officials decided to attempt to break some records with an aircraft known as the Lockheed SR-71 Blackbird.
The SR-71, unofficially known as the “Blackbird,” was a long-range, advanced, strategic reconnaissance aircraft developed from the Lockheed A-12 and YF-12A aircraft. The first flight of an SR-71 took place on Dec. 22, 1964, and the first SR-71 to enter service was delivered to the 4200th (later 9th) Strategic Reconnaissance Wing at Beale Air Force Base, Calif., in Jan. 1966.
As told by Angela Woolen in the article SR-71 pilots, crew relive absolute speed record, on Jul. 28, 1976, retired Maj. Gen. Eldon (Al) Joersz, the pilot, and retired Lt. Col. George Morgan, the reconnaissance systems officer (RSO), set the world absolute speed record for jet-powered airplanes with a speed of 2,193 mph.
The record still stands today.
Today, SR-71 #958, the Blackbird that made the speed record run is on display at the Museum of Aviation near Warner Robins, GA.
Noteworthy, during the record-breaking event, Joersz and Morgan experienced an inlet unstart that however didn’t prevent the iconic Blackbird to set the absolute speed record.
SR-71 pilot David Peters explains;
‘If Joersz and Morgan had just a normal unstart without a burner blow out if probably didn’t slow them down much but they certainly would have had the record higher without it.’
If it weren’t for the inlet unstart that temporarily jammed up an engine, they could have gone faster than 2,193 mph. In fact they could have stayed under Mach3.3.
This note is from George Morgan: ‘Al and I had the ACTUAL speed record. 2200 indicated in our equipment aboard 958!
“Just to clear up a couple of points. First an unstart does not usually cause the engine to shut down. In this case it was just an unstart of the inlet which can be recovered rather quickly. Second unstarts were much more likely in the 2.6 to 2.9 range especially in the climb. High Mach unstarts were much more rare.”
It is true that any SR-71 with any crew could’ve made that record breaking run. But the commander would’ve picked his most reliable crew that he had. And he picked Al Joersz and George Morgan to make the flight. In the early days of the SR-71 they really didn’t want to call any attention to the Blackbird. In the spirit of the bicentennial 200-year anniversary of the United States, President Ford asked if an SR could make the speed run. SR-71 commanders never said no to a President.
The plane flew through the first of its two passes at a much, much higher speed than what was required to set the record. Just before start of the second pass, one of the engines shut down. Before the engine could be restarted, the plane was well beyond the start line. The engine did recover from the unstart.
Capt. Al Joersz, the record-setting pilot, said, “By the time we’d gone through the checklist, we’d already passed the second gate thus officially starting the run. Still, we exited the gate at Mach 3.2.”
“If they hadn’t had the unstart when they were going through the gate, the record speed would’ve been higher. Their goal was to make 2200 mph.”
However, once the engine was restarted after the inlet unstart, Joersz and Morgan could’ve pushed the Blackbird to the limit and gone Mach 3.3, but in 1976 they really didn’t want anyone to know how fast the SR-71 could go. It was still classified. For this reason, the US Air Force (USAF) chose to set the speed record “very carefully” avoiding to disclose how fast the SR-71 could really go.
