Completing its final flight, Lockheed SR-71A 61-7972, flown by Lieutenant Colonel Raymond E. Yeilding and Lieutenant Colonel Joseph T. Vida, arrives at Washington Dulles International Airport, 6 March 1990, where it was turned over to the Smithsonian Institution National Air and Space Museum.
6 March 1990: On its final flight, Lieutenant Colonel Raymond E. (“Ed”) Yeilding and Lieutenant Colonel Joseph T. (“J.T.”) Vida established four National Aeronautic Association and three Fédération Aéronautique Internationale speed records with a Lockheed SR-71A Blackbird, U.S. Air Force serial number 61-7972.
Departing Air Force Plant 42 (PMD) at Palmdale, California, Yeilding and Vida headed offshore to refuel from a Boeing KC-135Q Stratotanker so that the Blackbird’s fuel tanks would be full before beginning their speed run. 972 entered the “west gate,” a radar reference point over Oxnard on the southern California coast, then headed east to Washington Dulles International Airport (IAD) at Washington, D.C.
The transcontinental flight, a distance of 2,404.05 statute miles (3,868.94 kilometers), took 1 hour, 7 minutes, 53.69 seconds, for an average of 2,124.51 miles per hour (3,419.07 kilometers per hour).
Intermediate closed-course records were also established: Los Angeles to Washington, D.C., 2,299.67 miles (3,700.96 kilometers), 1:04:19.89, averaging 2,144.83 m.p.h (3,451.77 km/h).; Kansas City to Washington, D.C., 942.08 miles (1,516.13 km), 25:58.53, 2,176.08 m.p.h. (3,502.06 km/h); and St. Louis to Cincinnati, 311.44 miles (501.21 km), 8:31.97, 2,189.94 m.p.h. (3,524.37 km/h).
Flight record data for 972’s record-setting transcontinental flight, prepared by V.A. Wright, Advanced Development Projects, Lockheed Aeronautical Systems Company.
This same SR-71 had previously set a speed record from New York to London of 1:54:56.4, averaging 1,806.957 m.p.h. (2,908.015 km/h). (It had to slow for inflight refueling.) Next, 972 set a record flying London to Los Angeles, 5,446.87 miles (8765.89 km), in 3 hours, 47 minutes, 39 seconds, averaging 1,435.49 m.p.h. (2,310.19 km/h). It also established an altitude record of 85,069 feet (25,929 meters).
This was 61-7972’s final flight. The total time on its airframe was 2,801.1 hours.
61-7972 is on display at the Steven V. Udvar-Hazy Center, Smithsonian Institution National Air and Space Museum.

Clarence Leonard “Kelly” Johnson. (guggenheimedal.org)
Clarence Leonard (“Kelly”) Johnson was born at Ishpeming, Michigan, United States of America, 27 February 1910. He was the third of five children of Peter Johnson, a stone mason, and Kjrstie Anderson Johnson. His parents were immigrants from Sweden.
C.L. Johnson, 1932 (Michiganensian)
Kelly Johnson attended Flint Central High School, graduating in 1928. After studying at a community college, Johnson transferred to the University of Michigan at Ann Arbor. He graduated in 1932 with a Bachelor of Science degree in Aeronautical Engineering (B.S.E. AeroE.). He won the Frank Sheehan Scholarship in Aeronautics, which enabled him to continue at the University to earn a Master of Science degree in Aeronautical Engineering (M.S.E.) in 1933.
Kelly Johnson started working as a tool designer for the Lockheed Aircraft Company in Burbank, California, in 1933. After transferring to the engineering department, he was assigned to the company’s Model 10 Electra project. Johnson identified a stability problem with the airplane’s design, and he was sent back to the University of Michigan to conduct a wind tunnel study which resulted in his proposal of the twin vertical tail configuration which was a characteristic of many Lockheed airplanes that followed. Johnson also served as a flight test engineer for the airplane.
A genius of aeronautical engineering and design, he was responsible for all of Lockheed’s most famous aircraft: the Lockheed Hudson and Neptune medium bombers, the P-38 Lightning twin-engine fighter, the P-80 Shooting Star, America’s first full-production jet fighter. He designed the beautiful Constellation airliner. The list is seemingly endless: The F-94 Starfire, F-104 Starfighter, U-2, A-12 Oxcart and the SR-71 Blackbird.

Kelly Johnson was married three times. He married Miss Althea Louise Young, who worked in Lockheed’s accounting department, in 1937. She died of cancer in December 1969. He then married Miss Maryellen Elberta Meade, his secretary, at Solvang, California, 20 May 1971. She died 13 October 1980 of complications of diabetes. He married his third wife, Mrs. William M. Horrigan (née Nancy M. Powers), a widow, and MaryEllen’s best friend, 21 November 1980. Johnson had no children.
Kelly Johnson retired from Lockheed in 1975 as a senior vice president. He remained on the board of directors until 1980.
Clarence Leonard Johnson died 21 December 1990 at St. Joseph’s Medical Center, Burbank, California, after a long period of hospitalization. He was buried at the Forest Lawn Memorial Park in the Hollywood Hills, Los Angeles, California.

De La Vaulx Medal
The following day, the same airplane, flown by two different crews, set a World Record for Altitude in Horizontal Flight at 85,068 feet (25,929 meters) and a World Record for Speed Over a Straight 15/25 Kilometer Course, 2,193.17 miles per hour (3,529.56 kilometers per hour). This second speed record became the new Absolute Speed Record, superseding the record set on this date by Alphonsus Bledsoe and John T. Fuller.
All six airmen were awarded the Henry De La Vaulx Medal by the FAI.
Today, 61-7958 is on display at the Museum of Aviation, Warner-Robins, Georgia. 32 of these long range strategic reconnaissance aircraft were built by the Lockheed Skunk Works.
