Mach 3.3: SR-71 Blackbird Could Go ‘Coast to Coast’ in A Little Over an Hour

The SR-71: Still the Fastest Plane on Earth – The SR-71 Blackbird spy plane, during its legendary lifetime, had plenty of famous flights in different parts of the world. But one of its most significant flights took place in the United States…all the way across the United States, in fact.

Recently, the Aviation Geek Club looked back on a certain flight of the famous plane…the last one.

SR-71 History 

It took place in March of 1990, when the SR-71 Blackbird was being flown from California to Washington, D.C., in order to be turned over to the National Air and Space Museum, where it remains to this day.

In the fight, from Air Force Plant 42 (PMD) at Palmdale to Dulles International Airport in Virginia, Lieutenant Colonel Raymond E. (“Ed”) Yeilding and Lieutenant Colonel Joseph T. (“J.T.”) Vida set four different speed records.

The SR-71 flew from St. Louis to Cincinnati in eight minutes and 32 seconds and from Los Angeles to Washington, overall, in 64 minutes and 20 seconds. The flight was mostly at Mach 3.3, which was considered the “operational limit” of the plane.

Yeilding, who flew more than 90 reconnaissance missions in the SR-71, remembered that day back in 2015, for Auburn Engineer magazine.

“I remember that day so well – March 6, 1990. I got up at 1 a.m., got to my briefing at 2 a.m., and into the suit and onto the flight line at 3:45. We planned our takeoff for 4:30 – it was 7:30 in Washington – from Palmdale in the company of a small crowd that gathered for the last flight,” Yeilding told the magazine at his alma mater, Auburn University.

It was a challenging mission, for many reasons, he told the magazine.

“The first thing that we had to do was air refuel – the routine was to take off with half a load of fuel for safety, so we’d be light enough to climb in case an engine failed just after lift-off. At 27,000 feet, we did that, with a couple of KC-135Q tankers over the Pacific Ocean. Then, with a full load, we turned east, lit the afterburners, and had a 200-mile running start as we accelerated. Fuel was very tight for the coast-to-coast flight, so we planned to cross the West Coast accelerating through Mach 2.5 at 63,000 feet, before reaching our cruise speed at 76,000 feet,” he said.

He also has memories of the latter part of the flight.

“We overflew Wilmington, just below Philly, and were still supersonic in a descending left-hand turn, heading toward Washington. When we became subsonic we met another KC-135Q and took on more fuel at 25,000 feet. At Dulles International we made two low passes, one with afterburner, near the crowd that was waiting. We wanted to give them a look at the shock diamonds in the glowing afterburner plumes, and before landing, rocked the wings in salute.”

    The most amazing, piloted, atmospheric breathing airplane ever. And to think its predecessor, the CIA A-12 Oxcart, the aircraft the SR-71 is based on, flew for the first time almost 60 years ago on April 26th 1962. And the SR-71’s records still have not been broken in 57 years (the SR-71 first flew on December 22 1964). Hats off to Kelly Johnson and his team at Lockheed’s Skunk Works.
