4 September 1949: At 11:30 a.m., Sunday morning, the prototype Bristol Brabazon Mk.I, G-AGPW, made its first flight at Filton Aerodrome. Chief Test Pilot Arthur J. “Bill” Pegg was in command with Walter Gibb as co-pilot. An 8-man flight test crew was also aboard. A crowd of spectators, estimated at 10,000 people, were present.

Designed as a transatlantic commercial airliner, development of the Type 167 began in 1943. The Mk.I prototype, G-AGPW, had been rolled out in December 1948. On 3 September 1949, the flight test crew performed a series of taxi tests.
The first flight lasted 26 minutes. The Brabazon had reached 3,000 feet (914 meters) and 160 miles per hour (257 kilometers per hour).

The Bristol Aeroplane Company Type 167 Brabazon Mk.I was a very large low-wing monoplane, designed to carry 100 passengers on transatlantic flights. it had been named to honor John Theodore Cuthbert Moore-Brabazon 1st Baron Brabazon of Tara, was the first airplane pilot to be issued an aviator’s certificate by the Royal Aero Club of the United Kingdom. He had previously been assigned certificate number 40 of the Fédération Aéronautique Internationale. He was issued Certificate Number 1 in England. He was a very important figure in the development of the British aeronautical industry.

The Type 167 was slightly larger than the United States Air Force Convair B-36A intercontinental strategic bomber. It was 177 feet, 0 inches (53.950 meters) long with a wingspan of 230 feet, 0 inches (70.104 meters) and overall height of 50 feet, 0 inches (15.240 meters). The fuselage had a maximum diameter of 25 feet (7.62 meters).
The leading edge of the inboard section of the Brabazon’s wing was swept 4° 16′ and had no dihedral, while the outer section was swept 14° 56′ with 2° dihedral. The wings had an angle of incidence of +3° 30′. The chord narrowed from 31 feet, 0 inches (9.449 meters) at the root, to 10 feet, 0 inches (3.048 meters) at the tip. The wings’ maximum thickness was 6 feet, 6 inches (1.981 meters). The Mk.I’s wing area was 5,317 square feet (494 square meters).
The horizontal stabilizer had a span of 75 feet, 0 inches (22.860 meters). The angle of incidence was +2° and there was no dihedral. The stabilizer’s area was 692 square feet (64.3 square meters).
The airplane’s empty weight was 169,500 pounds (76,884 kilograms), and its maximum takeoff weight of 290,000 pounds (131,542 kilograms). For the first flight, its gross weight was 200,000 pounds (90,718 kilograms).

The prototype was powered by eight air-cooled, supercharged, 3,271.87-cubic-inch-displacement (53.62 liter) Bristol Centaurus 20 eighteen-cylinder radial engines. They had a cruise power rating of 1,640 horsepower at 22,000 feet (6,706 meters); maximum continuous power and maximum climb power rating of 2,190 horsepower at 5,000 feet (1,524 meters); and 2,500 horsepower for takeoff. Each pair of engines drove a set of coaxial counter-rotating three-bladed Rotol constant-speed wooden propellers with a diameter of 16 feet, 0 inches (4.877 meters).
“Each Bristol Centaurus engine was coupled to a propeller gearbox at a 32-degree angle.” (Airbus, Filton)
Power was transmitted from each engine by an angled drive shaft to separate beveled gears in a dual reduction gear unit. The reduction gear ratio was 0.400:1. For one-engine-out operation, the effected propeller would be feathered, while the other engine of the pair continued to power the other counter-rotating propeller. The propellers were reversible for braking on landing.
Turboprop engines were planned for the Brabazon Mk.II.

Estimated performance of the Brabazon Mk.I (before flight testing was completed) was a cruise speed of 250 miles per hour (402 kilometers per hour), and maximum speed of 300 miles per hour (483 kilometers per hour), both at 25,000 feet (7,620 meters), the airplane’s service ceiling.
The maximum fuel capacity of the Mk.I was 13,650 gallons (51,671 liters), giving a maximum range at cruise speed of 5,460 miles (8,787 kilometers). This was sufficient for a flight from London to New York with the required fuel reserve.
Only one Brabazon Mk.I was built. The prototype Mk.II was never completed. The project was cancelled in 1952. The total cost of the Brabazon program was approximately £6,500,000 (estimated at £170,981,807, or $221,489,833 in 2017). G-AGPW was eventually scrapped.

Beryl Markham steps out of the cockpit of the Percival Vega Gull, probably late August 1936. (Library of Congress)
4–5 September 1936: At 6:50 p.m., British Summer Time, Beryl Markham departed RAF Abingdon, Oxfordshire, England, aboard a turquoise blue and silver Percival P.10 Vega Gull, registration VP-KCC. Her intended destination was New York City, across the Atlantic Ocean in America.
The airplane flown by Mrs. Markham, serial number K.34, was brand-new, built for John Evans Carberry (formerly, 10th Baron Carbery) for his entry in The Schlesinger air race from London, England, to Johannesburg, South Africa. He loaned the airplane to her for the transatlantic flight on condition that she would return it to England by mid-September, in time for the start of the race.

Designed by Edgar Percival and built by Percival Aircraft Limited at Gravesend, the P.10 Vega Gull was a four-place, single engine monoplane with fixed landing gear. Known as the K-series, it was a development of the previous D-series Gull Six. The airplane was 25 feet, 6 inches (7.772 meters) long with a wingspan of 39 feet, 6 inches (12.040 meters) and height of 7 feet, 4 inches (2.235 meters). The standard airplane had an empty weight of 1,740 pounds (789.25 kilograms) and loaded weight of 3,250 pounds (1,474.2 kilograms). K.34, the airplane flown by Markham, carried two auxiliary fuel tanks in the passenger compartment, for a total capacity of 255 gallons (965.3 liters).
The Vega Gull was powered by an air-cooled, normally-aspirated, 9.186 liter (560.573-cubic-inch-displacement) de Havilland Gypsy Six I, an inverted inline six-cylinder overhead valve (OHV) engine. The engine had a compression ratio of 5.25:1. It was rated at 184 horsepower at 2,100 r.p.m., and 205 horsepower at 2,350 r.p.m. for takeoff. The direct-drive engine turned a two-bladed Ratier variable-pitch propeller. The Gypsy Six I weighed 432 pounds (196 kilograms).
The Vega Gull had a cruising speed of 150 miles per hour (241 kilometers per hour) and a maximum speed of 174 miles per hour (280 kilometers per hour). The service ceiling was 17,000 feet (5,181.6 meters). Estimated range with the auxiliary fuel tank was 3,800 miles (6,115.5 kilometers).

John Carberry was a resident of Colony and Protectorate of Kenya so the new airplane received the civil registration marking, VP-KCC. It was named The Messenger.
Beryl Markham was an experienced airplane pilot who had most recently been employed as Chief Pilot, Air Cruisers Limited, owned by a French financier, François Dupré. She was certified both as a pilot and an aircraft mechanic, and had recently had her pilot’s license endorsed for “All Types.”

Mrs. Markham and the airplane were ready for the solo transoceanic flight by 1 September, but were delayed by bad weather, with worse forecast. Captain Percival had recommended that she start from RAF Abingdon because its 1 mile runway (1.6 kilometers) would give the overweight airplane a longer takeoff run.
By the 4th, however, she was impatient with waiting and decided to takeoff regardless of the weather. She arrived at the airfield at about 5:00 p.m. Her takeoff was delayed while the runway was cleared of a wrecked bomber that had been overturned by the high winds.
Because of the high winds, the Vega Gull was airborne in just 600 yards (550 meters).
Beryl Markham and the Percival P.10 Vega Gull K.34, with Kenyan civil registration VP-KCC, westbound over England, 4 September 1936. (Henry How, Daily Mirror)
From the start, Markham encountered heavy rain, low clouds, fog, and gale force winds. Almost immediately, her carefully-prepared chart was blown out of a cockpit window. She flew most of the distance at an altitude of about 2,000 feet (610 meters). If she climbed higher, the rain turned to ice. If she flew lower she was in danger of the winds forcing her into the sea below. She had hoped to have the light of a nearly full moon as she crossed the Atlantic at night but the weather was so bad that she flew by reference to her instruments for the entire crossing.
During the transatlantic flight the Percival Vega Gull was sighted by several ships which reported her position. Although the airplane had a cruising speed of 150 miles per hour (241 kilometers per hour), because of the headwinds, Markham estimated her rate of advance at just 90 miles per hour (145 kilometers per hour). With the airplane running on fuel from the final tank, which should have lasted 11 hours, the gauge indicated that it was being consumed at a higher rate. She estimated her position as nearing Newfoundland but with rain, clouds and fog, she was only able to see brief views of the ocean below.
The dawn broke through the clouds. The wind changed and I stopped being so silly. I wouldn’t have imagined that there was an expanse of desolation so big in the whole world as the waste of sky and water I saw go past me since I left Abingdon. . . It was fog, rain, sleet for hours on end. If I climbed it was sleet, if I dropped it was rain. If I skimmed the sea it was fog. I couldn’t see anything beyond my wingtips. . .
That tank, on which I was banking my all, didn’t last eleven hours. It lasted nine hours and five minutes. . . I watched that tank getting emptier and emptier and still saw nothing but sea and clouds and mist. . . I could see nothing to save me. Good old Messenger was going to stop any moment and I said to myself, “If I’m going to go, now is the time to get ready for it.” The only thing anywhere around was fog, great hefty banks of it. And then I saw the coast. The beautiful coast. I’ve never seen land so beautiful. . . But then the engine began to go “put, put, put.”
. . . I knew then that I had to come down and made for the beach. I couldn’t land there; there was nothing but great big rocks and Messenger and I would have been dashed to pieces. I went inland.
My engine was missing badly now. It was sheer agony to watch my petrol gauge . . . I peered around for a field to land on. I was still peering when the engine stopped.
—Beryl Markham, quoted in Straight on Till Morning, by Mary S. Lovell, St. Martin’s Press, New York, 1987, Chapter 9 at Pages 177–178.
The field turned out to be a peat bog at Baliene Cove on Cape Breton Island, Nova Scotia, Canada. The airplane nosed over in the soft surface. Beryl Markham struck her head and was briefly knocked unconscious. She soon climbed out of the damaged Vega Gull and was taken to a nearby farm where help soon arrived.
Beryl Markham did not reach her intended destination of New York City. But what she did accomplish was the first East-to-West solo crossing of the Atlantic Ocean by a woman. Although Amelia Earhart had flown solo across the Atlantic in her Lockheed Vega four years earlier, her crossing was West-to-East. Because of the prevailing weather patterns, the westerly crossing is considered much more difficult.
Beryl and The Messenger returned to England aboard the passenger liner RMS Queen Mary. Although the damage was repaired, it was not in time to compete in The Schlesinger. John Carberry sold VP-KCC to Dar-es-Salaam Airways. It was written off in Tanganyika in August 1937, and de-registered in March 1938.
Beryl Markham was a remarkable woman whose exploits are too great to touch on here. She wrote West with the Night, which was considered by author Ernest Hemingway to be “a bloody wonderful book.” She died at her home in Nairobi, Kenya, 3 August 1986, at the age of 83.

4 September 1936: Louise Thaden was the first woman to win the Bendix Trophy Race when she and her co-pilot, Blanche Wilcox Noyes, flew a Beechcraft C17R “Staggerwing,” NR15835 (manufacturer’s serial number C17R-77), from Floyd Bennett Field, Brooklyn, New York, to Mines Field, Los Angeles, California, in 14 hours, 55 minutes, 1.0 seconds. With one fuel stop at the Beech Aircraft Company factory in Wichita, Kansas, Thaden and Noyes had averaged 165.35 miles per hour (266.11 kilometers per hour), even though—against the advice of Walter Beech—they had maintained only 65% power for the entire race. They landed at 4:49.49 p.m., Pacific Standard Time (00:49, 5 September, UTC).
In addition to the trophy, Mrs. Thaden won a prize of $4,500 for first place, plus $2,500 for the fastest speed in the race set by a woman (unaccompanied by a man).
She was also awarded the Harmon Trophy.
Laura Ingalls, flying her Lockheed Orion 9D Special, NR14222, finished in second place, arriving 45 minutes after Thaden and Noyes, at 5:54.28 p.m.. William Warner finished in third place in a Vultee V-1A, and George Pomeroy was fourth flying a Douglas DC-2 transport. And in fifth place was Amelia Earhart and Helen Richey in Earhart’s Lockheed Model 10E Electra Special, NR16020.

Iris Louise McPhetridge was born 12 November 1905 at Bentonville, Arkansas. She was the first of three daughters of Roy Fry McPhetridge, owner of a foundry, and Edna Hobbs McPhetridge. She was educated at the University of Arkansas at Fayetteville, a member of the Class of 1927. She was president of the Delta Delta Delta (ΔΔΔ) Sorority, Delta Iota (ΔΙ) Chapter, head sports for basketball and president of The Panhellenic.
Louise McPhetridge had been employed by Walter Beech as a sales representative at Wichita, Kansas, and he included flying lessons with her employment. She received her pilot’s license from the National Aeronautic Association, signed by Orville Wright, 16 May 1928.
Mrs Thaden set an FAI World Record for Altitude of 6,178 meters (20,269 feet) over Oakland, California, 7 December 1928.¹ On 17 March 1929, she set an FAI record for duration of 22 hours, 3 minutes.²
In 1929, she was issued Transport Pilot License number 1943 by the Department of Commerce. Mrs. Thaden was the fourth woman to receive an Airline Transport Pilot rating.

Miss McPhetridge married Mr. Herbert von Thaden at San Francisco, California, 21 July 1928. Thaden was a former military pilot and an engineer. They would have two children, William and Patricia.
Thaden had founded the Thaden Metal Aircraft Company, builder of the all-metal Thaden T-1, T-2, and T-4 Argonaut. Thaden went on to design molded plywood furniture for the Thaden-Jordan Furniture Corporation. His designs are considered to be works of art, and individual pieces sell for as much as $30,000 today.

Louise Thaden served as secretary of the National Aeronautic Association, and was a co-founder of The Ninety-Nines. She served as that organization’s vice president and treasurer. She set several world and national records and was awarded the national Harmon Trophy as Champion Aviatrix of the United States in 1936.
Louise Thaden stopped flying in 1938. She died at High Point, North Carolina, 9 November 1979.

The Beechcraft C17R was single-engine, single-bay biplane operated by a single pilot and could carry up to four passengers in its enclosed cabin.The basic structure was a welded tubular steel frame with wood formers and stringers. The wings and tail surfaces were built of wood spars and ribs with the leading edges and wing tips covered with plywood. The airplane was covered with doped fabric, except the cabin and engine, which were covered in sheet metal. It was equipped with electrically-operated retractable landing gear and wing flaps.
The Beechcraft Staggerwing got its name because its lower wing was placed ahead of the upper wing (negative stagger). While most biplanes had staggered wings, the Staggerwing was unusual in having negative stagger. This not only increased the pilot’s field of vision, but improved the airplane’s stability in a stall. The Staggerwing was a fast airplane for its time and set several speed and altitude records.
The Beech C17R was 24 feet, 5 inches (7.442 meters) long with a wingspan of 32 feet, 0 inches (9.754 meters) and overall height of 8 feet, 2 inches (2.489 meters). According to the Bureau of Air Commerce license certificate dated 9 October 1936, C17R-81 had an empty weight of 2,393 pounds (1,085 kilograms), and its maximum gross weight was 3,900 pounds (1,769 kilograms).

While most biplanes had staggered wings, the Staggerwing was unusual in having negative stagger. This not only increased the pilot’s field of vision, but improved the airplane’s stability in a stall. The leading edge of the Model C17 upper wing was 2 feet, 1 inches (0.635 meters) aft of the lower wing. The leading edges had 0° sweep. Both wings had an angle of incidence of 3°. The upper wing had no dihedral, but the lower wing had +1°. The mean vertical gap between the wings was 5 feet (1.524 meters), and the chord of both wings was 5 feet, 0 inches (1.524 meters). The total wing area was 273 square feet (25.4 square meters). The horizontal stabilizer had 0° incidence, while the vertical fin was offset 0° 43′ to the left of the airplane’s centerline.

The Staggerwing was offered with a selection of engines of different displacements and horsepower ratings. The C17R was powered by an air-cooled, supercharged, 971.930-cubic-inch-displacement (15.927 liter) Wright Whirlwind 440 (R-975E3), a 9-cylinder direct-drive radial engine with a compression ratio of 6.3:1. The R-975E3 was rated at 420 horsepower at 2,200 r.p.m., and 440 horsepower at 2,250 r.p.m. for takeoff, burning 92-octane gasoline. The engine was 43.00 inches (1.092 meters) long and 45.25 inches (1.149 meters) in diameter. It weighed 700 pounds (318 kilograms). The serial number of the engine installed in C17R-81 was 12885. It drove a two-bladed adjustable pitch Hamilton Standard propeller with a diameter of 8 feet, 6 inches (2.591 meters), serial number 18560.
This engine gave the C17R Staggerwing a cruise speed of 195 miles per hour (314 kilometers per hour) at 5,000 feet (1,524 meters), 202 miles per hour (325 kilometers per hour) at 10,000 feet (3,048 meters) and maximum speed of 211 miles per hour (340 kilometers per hour). The service ceiling was 21,500 feet (6,553 meters) and its range with standard fuel capacity, 98 gallons (371 liters) was 800 miles (1,288 kilometers).

The Beechcraft C17R flown by Louise Thaden to win the Bendix Trophy, serial number C17R-77, had already been sold to the government of the Republic of Honduras, but Walter Beech let Thaden use it for the race before delivering to the owner. It was painted in Sherwin Williams Consolidated Blue with white stripes. The rear passenger seats were removed and a 56 gallon (212 liter) auxiliary fuel tank installed in their place.
After the race, the Staggerwing overhauled, repainted Insignia Blue with silver wings, and was flown to Central America by Paul E. Zimmerman. It was assigned to the Escuela Militar de Aviacion.
Three C17R Staggerwings have been registered as N15835, including serial numbers C17R-74; C-17R-77, the Bendix race winner; and C17R-81, which was owned by Thaden. Current FAA records indicate that the first, C17R-74, is currently registered N15835.

4 September 1922: First Lieutenant James H. (“Jimmy”) Doolittle, Air Service, United States Army, made the first transcontinental crossing of the United States in a single day when he flew a DH.4B-1-S single-engine biplane, Air Service Serial Number 22-353, from Pablo Beach, Florida, ¹ to Rockwell Field, San Diego, California, a distance of 2,106 miles (3,390 kilometers). He made one refueling stop at Kelly Field, San Antonio, Texas, which lasted 1 hour, 16 minutes. The total duration of the flight was 21 hours, 19 minutes.

Lieutenant Doolittle was awarded the Distinguished Flying Cross for “demonstrating the possibility of moving Air Corps units to any portion of the United States in less than 24 hours.”
Maintenance technicians service Lieutenant Doolittle’s DH-4B-1-S at Kelly Field.
The Airco DH.4 was a very successful airplane of World War I, designed by Geoffrey de Havilland. It was built by several manufacturers in Europe and the United States. The DH-4B was a rebuilt DH.4 with fuel capacity increased to 110 gallons (420 liters). The DH-4B was 30 feet, 6 inches (9.296 meters) long with a wingspan of 43 feet, 6 inches (13.259 meters) and height of 10 feet, 4 inches (3.150 meters). Loaded weight of the standard DH-4B was 3,557 pounds (1,613.4 kilograms).
In place of the Rolls-Royce Eagle VII V-12 of the British-built version, Army Air Service DH-4s were powered by a water-cooled, normally-aspirated, 1,649.336-cubic-inch-displacement (27.028 liter) Liberty L-12 single overhead cam (SOHC) 45° V-12 engine with a compression ratio of 5.4:1. The Liberty produced 408 horsepower at 1,800 r.p.m. The L-12 as a right-hand tractor, direct-drive engine. It turned turned a two-bladed fixed-pitch wooden propeller. The Liberty 12 was 5 feet, 7.375 inches (1.711 meters) long, 2 feet, 3.0 inches (0.686 meters) wide, and 3 feet, 5.5 inches (1.054 meters) high. It weighed 844 pounds (383 kilograms).
The Liberty L12 aircraft engine was designed by Jesse G. Vincent of the Packard Motor Car Company and Elbert J. Hall of the Hall-Scott Motor Company. This engine was produced by Ford Motor Company, as well as the Buick and Cadillac Divisions of General Motors, The Lincoln Motor Company (which was formed by Henry Leland, the former manager of Cadillac, specifically to manufacture these aircraft engines), Marmon Motor Car Company and Packard. Hall-Scott was too small to produce engines in the numbers required.
This same airplane, DH.4B-1-S, A.S. No. 22-353, was flown from the Gulf of Mexico to the Canadian border by Lieutenant H.G. Crocker, 26 May 1923.

Jimmy Doolittle was one of America’s foremost pioneering aviators. He set many records, won air races, tested and developed new flying equipment and techniques. He was a highly-educated military officer, having earned his Bachelor of Arts from the University of California Berkeley School of Mines, and M.S and D.Sc. degrees in Aeronautical Engineering from the Massachusetts Institute of Technology.
During World War II Colonel Doolittle planned and led the famous Halsey-Doolittle Raid against Japan, 18 April 1942, for which he was awarded the Medal of Honor. As a brigadier general he commanded Twelfth Air Force in North Africa. Promoted to major general, he was given command of the Fifteenth Air Force in the Mediterranean Theater. From 1943 until 1945, Lieutenant General Doolittle commanded Eighth Air Force. He was preparing his command to move against Japan, equipped with Boeing B-29 Superfortress bombers when World War II came to an end.

After the war, Lieutenant General Doolittle was placed on the inactive list. On 4 April 1985, by Act of Congress, James H. Doolittle was promoted to General.
General James Harold Doolittle is the only person to be awarded both the Medal of Honor and the Medal of Freedom. He died 27 September 1993 at the age of 96 years. He was buried at the Arlington National Cemetery, Arlington, Virginia.

3 September 1954: At the Dayton Air Show, being held for the first time at the James M. Cox Municipal Airport, Major John L. (“Jack”) Armstrong, U.S. Air Force, flew his North American Aviation F-86H-1-NH Sabre, 52-1998, to a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 500 Kilometers Without Payload, averaging 1,045.206 kilometers per hour (649.461 miles per hour). ¹
Similar to the F-86H-1-NH Sabre flown by Captain Armstrong, this is F-86H-10-NH 53-1298. (U.S. Air Force)
The North American Aviation F-86H was a fighter-bomber variant of the famous Sabre Jet day fighter. It was equipped with a much more powerful General Electric J73-GE-3 turbojet engine. The engine was larger that the J47 used in previous F-86 models, and this required a much larger air intake and airframe modifications. The fuselage was 6 inches deeper and two feet longer than the F-86F. This accommodated the new engine and an increase in fuel load. The tail surfaces were changed with an increase in the height of the vertical fin and the elevators were changed to an “all-flying” horizontal stabilizer. The first F-86Hs built retained the six Browning AN-M3 .50 caliber machine guns of the F-86F, but this was quickly changed to four Pontiac M39 20 millimeter revolver cannon.

The F-86H Sabre was 38 feet, 10 inches (11.836 meters) long with a wingspan of 39 feet, 1 inch (11.913 meters) and overall height of 14 feet, 11 inches (4.547 meters). Empty weight was 13,836 pounds (6,276 kilograms) and gross weight was 24,296 pounds (11,021 kilograms).
The F-86H was powered by a General Electric J73-GE-3D or -3E engine, a single-spool, axial-flow, turbojet engine, which used a 12-stage compressor section with variable inlet vanes, 10 combustion chambers and 2-stage turbine section. It produced 8,920 pounds of thrust (39.68 kilonewtons) at 7,950 r.p.m. (%-minute limit). The J73 was 12 feet, 3.2 inches (3.739 meters) long, 3 feet, 0.8 inches (0.935 meters) in diameter and weighed 3,650 pounds (1,656 kilograms).
The F-86H had a maximum speed of 601 knots (692 miles per hour/1,113 kilometers per hour) at Sea Level and 536 knots (617 miles per hour (993 kilometers) at 35,000 feet (10,668 meters). The fighter bomber had an initial rate of climb of 12,900 feet per minute (65.53 meters per second) and it could reach 30,000 feet (9,144 meters) in 5.7 minutes. The service ceiling was 50,800 feet (15,484 meters). With a full load of bombs, the F-86H had a combat radius of 350 nautical miles (402 statute miles/648 kilometers) at 470 knots (541 miles per hour (870 kilometers per hour). The maximum ferry range was 1,573 nautical miles (1,810 statute miles/2,913 kilometers).
F-86H Sabres (after the first ten production airplanes) were armed with four Pontiac M39 20 mm autocannon with 150 rounds of ammunition per gun. In ground attack configuration, it could carry a maximum bomb load of 2,310 pounds (1,048 kilograms), or one 12–24 kiloton Mark 12 “Special Store” that would be delivered by “toss bombing.”
The F-86H Sabre became operational in 1954. 473 F-86H Sabres were built before production ended. By 1958 all that remained in the U.S. Air Force Inventory were reassigned to the Air National Guard. The last one was retired in 1972.

John Leroy Armstrong was born in Orange County, California, 19 July 1922. He was the fourth child of Milton Williams Armstrong, an engineer, and Olive M. Meyer Armstrong. As a child, he was called “Jake.”
Major Armstrong had been a fighter pilot during World War II, flying Lockheed P-38 Lightnings, initially with the 554 Fighter Training Squadron, 496th Fighter Training Group.
On 13 March 1944, Armstrong made a forced landing at North Killingholme when his fighter ran out of fuel.
2nd Lieutenant Armstrong was assigned to the 79th Fighter Squadron, 20th Fighter Group based at RAF Kings Cliffe, Northamptonshire, England, 26 March 1944. He flew the Lockheed P-38 Lightning.

The 79th transitioned to the P-51 Mustang. Armstrong was promoted to first lieutenant 26 June 1944. He was officially credited with having destroyed one enemy Focke-Wulf Fw 190. On 28 August 1944, while flying his 30th combat mission, his North American Aviation P-51D-5-NA Mustang, 44-13791, Guardian Angel, was shot down by anti-aircraft gunfire while he was attacking a railway roundhouse at Bad Greuznach, Germany. Armstrong bailed out but was captured. He was held as a prisoner of war at Stalag Luft I at Barth, Western Pomerania. Armstrong was returned to U.S. military control in June 1945.
Major Armstrong had been awarded the Distinguished Flying Cross, the Air Medal with five oak leaf clusters (six awards), the Purple Heart, the Prisoner of War Medal, World War II Victory Medal, and the European-African-Middle Eastern Campaign Medal.
Two days after setting the speed record, Jack Armstrong was attempting to increase his record speed. The Sabre broke up in flight and Major Armstrong was killed.
John Leroy Armstrong’s remains were buried at the Loma Vista Memorial Park, Fullerton, California, 11 September 1954.
This exhibit at the National Museum of the United States Air Force, Wright-Patterson AFB, Ohio, commemorates Major Armstrong’s record-setting flight. His flight helmet is included in the display. Visible behind the display case is North American Aviation F-86H-10-NH Sabre 53-1352. (U.S. Air Force)
