16 July 1953: Lieutenant Colonel William F. Barns, United States Air Force, set a Fédération Aéronautique Internationale (FAI) absolute World Record for Speed Over a 3 Kilometer Straight Course at the low-altitude course at the Salton Sea, California. ¹

Colonel Barns flew this North American Aviation F-86D-35-NA Sabre, serial number 51-6145, a radar-equipped all-weather interceptor. Lieutenant Colonel Barns was the Air Material Command’s pilot representative at the North American Aviation Los Angeles plant. The Sabre was a standard production airplane, the first Block 35 model built. It was fully loaded with twenty-four 2.75-inch (70 millimeter) aerial rockets.

Barns made the FAI-required four passes—two in each direction—in the Sabre interceptor. His four passes were timed at 720.574, 710.515, 721.351, and 710.350 miles per hour. (1,159.651, 1,143.463, 1,160.902, and 1,143.198 kilometers per hour).

Barns averaged 715.745 miles per hour (1,151.88 kilometers per hour)  at only 125 feet (38 meters) above the surface. The air temperature was 105 °F. (40.5 °C.)

The surface of the Salton Sea is -236 feet (-71.9 meters)—below Sea Level. Barns’ Sabre was flying at -111 feet (-33.8 meters). Under these conditions, the speed of sound, Mach 1, was 794 miles per hour (1,278 kilometers per hour), so the margin between the record speed and the onset of transonic compressibility effects was increased. Barns’ Sabre reached a maximum 0.91 Mach under these conditions.

The Associated Press reported the event:

Air Force Colonel Breaks Record

THERMAL, Calif. (AP)—An Air Force colonel flashed to a new air speed record of 715.7 miles per hour Thursday in a north American F-86D Sabre Jet.

Skimming over the hot beach of Southern California’s Salton Sea, Lt. Col. William F. Barns, 32, broke the record set last Nov. 19 over the same run by Capt. J. Slade Nash of Edwards Air Force Base.

On his first try, Barns averaged 713.6 miles per hour, a record performance, but came back a half hour later to beat that.

The airplane could not exceed 500 meters altitude (1,640 feet) at any time after takeoff on the trial, and the 3-kilometer dash had to be made below 100 meters (328 feet).

The Daily Illini, 17 July 1953, Vol. 82, Number 189, at Page 1, Column 2.

The same F-86D, 51-6145, flown by Captain Harold E. Collins, set an FAI World Record for Speed Over a 15/25 Kilometer Straight Course of 1,139.219 kilometers per hour (707.878 miles per hour) at Vandalia. Ohio, 1 September 1953. ²

William Frederick Barns was born 30 August 1920 at Baltimore, Maryland. He was the son of Claude Cox Barns and Nellie C. Hedrick Barns. The family moved to the Hawaiian Islands in 1925. He attended Theordore Roosevelt High School, in Honolulu. In 1940, William was employed as a clerk at the Bishop National Bank.

Barns began civilian flight training at John Rodgers Field near Honolulu in 1941, and was at the airfield during the attack on the Hawaiian Islands by the Imperial Japanese Navy, 7 December 1941. Barns enlisted in U.S. Army Air Corps 13 April 1942. He had brown hair and eyes, was 5 feet, 10 inches (1.78 meters) tall, and weighed 138 pounds. After qualifying as a pilot at Luke Field, Arizona, Barns was commissioned as a second lieutenant, U.S. Army Air Forces.

During World War II, Barns flew 210 combat missions with the 324th Fighter Group. He was awarded the Distinguished Flying Cross and the Silver Star.

Colonel Barns married Miss Marylouise Hamilton at the Flyer’s Chapel of the Mission Inn, Riverside, California, 18 August 1947. They had two children, Terrie and Bill. At the time of Barn’s world speed record, the family resided in Palos Verdes Estates, a few miles south of the North American factory.

Colonel Barns retired from the U.S. Air Force, 31 May 1966. He died in Phoenix, Arizona, 17 April 1995.

North American Aviation F-86D-1-NA Sabre 50-463. (North American Aviation, Inc.)

The F-86D was an all-weather interceptor developed from North American Aviation F-86 Sabre day fighter. It was the first single-seat interceptor and it used a very sophisticated—for its time—electronic fire control system. It was equipped with radar and armed with twenty-four unguided 2.75-inch (69.85 millimeter) diameter Mark 4 Folding-Fin Aerial Rockets (FFAR) rockets carried in a retractable tray in its belly.

The aircraft was so complex that the pilot training course was the longest of any aircraft in the U.S. Air Force inventory, including the Boeing B-47 Stratojet.

The F-86D was larger than the F-86A, E and F fighters, with a wider fuselage. Its length was increased to 40 feet, 3 inches (12.268 meters) with a wingspan of 37 feet, 1.5 inches (11.316 meters), and its height is 15 feet, 0 inches (4.572 meters). The interceptor had an empty weight of 13,518 pounds (6,131.7 kilograms), and maximum takeoff weight of 19,975 pounds (9,060.5 kilograms). It retained the leading edge slats of the F-86A, F-86E and early F-86F fighters. The horizontal stabilizer and elevators were replaced by a single, all-moving stabilator. All flight controls were hydraulically boosted. A “clamshell” canopy replaced the sliding unit of earlier models

The F-86D was powered by a General Electric J47-GE-17 engine. This was a single-shaft, axial-flow turbojet with afterburner. The engine had a 12-stage compressor, 8 combustion chambers, and single-stage turbine. The J47-GE-17 was equipped with an electronic fuel control system which substantially reduced the pilot’s workload. It had a normal (continuous) power rating of 4,990 pounds of thrust (22.20 kilonewtons); military power, 5,425 pounds (24.13 kilonewtons) (30 minute limit), and maximum 7,500 pounds of thrust (33.36 kilonewtons) with afterburner (15 minute limit). (All power ratings at 7,950 r.p.m.) It was 18 feet, 10.0 inches (5.740 meters) long, 3 feet, 3.75 inches (1.010 meters) in diameter, and weighed 3,000 pounds (1,361 kilograms).

The maximum speed of the F-86D was 601 knots (692 miles per hour/1,113 kilometers per hour) at Sea Level, 532 knots (612 miles per hour/985 kilometers per hour) at 40,000 feet (12,192 meters), and 504 knots (580 miles per hour/933 kilometers per hour)at 47,800 feet (14,569 meters).

The F-86D had an area intercept range of 241 nautical miles (277 statute miles/446 kilometers) and a service ceiling of 49,750 feet (15,164 meters). The maximum ferry range with external tanks was 668 nautical miles (769 statute miles/1,237 kilometers). Its initial rate of climb was 12,150 feet per minute (61.7 meters per second) from Sea Level at 16,068 pounds (7,288 kilograms). From a standing start, the F-86D could reach its service ceiling in 22.2 minutes.

The F-86D was armed with twenty-four 2.75-inch (69.85 millimeter) unguided Folding-Fin Aerial Rockets (FFAR) with explosive warheads. They were carried in a retractable tray, and could be fired in salvos of  6, 12, or 24 rockets. The FFAR was a solid-fuel rocket. The 7.55 pound (3.43 kilogram) warhead was proximity-fused, or could be set for contact detonation, or to explode when the rocket engine burned out.

The F-86D’s radar could detect a target at 30 miles (48 kilometers). The fire control system calculated a lead-collision-curve and provided guidance to the pilot through his radar scope. Once the interceptor was within 20 seconds of its target, the pilot selected the number of rockets to fire and pulled the trigger, which armed the system. At a range of 500 yards (457 meters), the fire control system launched the rockets.

A potential adversary of the North American Aviation F-86D Sabre all-weather interceptor was the Tupolev Tu-85 long-range strategic bomber.

Between December 1949 and September 1954, 2,505 F-86D Sabres (sometimes called the “Sabre Dog”) were built by North American Aviation. There were many variants (“block numbers”) and by 1955, almost all the D-models had been returned to maintenance depots or the manufacturer for standardization. 981 of these aircraft were modified to a new F-86L standard. The last F-86D was removed from U.S. Air Force service in 1961.

After its service with the United States Air Force, the world-record-setting Sabre, 51-6145, was transferred to NATO ally, the Royal Hellenic Air Force.

Major General Vladimir Sergeyevich Ilyushin, Hero of the Soviet Union

14 July 1959: At Podmoskovnoe, USSR, famed Soviet test pilot Vladimir Sergeyevich Ilyushin flew the Sukhoi T-43-1, a prototype of the Su-9 interceptor, to a Fédération Aéronautique Internationale (FAI) World Record for Altitude of 28,852 meters (94,659 feet).¹

Vladimir Sergeyevich Ilyushin was the son of Sergey Ilyushin, the Soviet aircraft designer. He made the first flights of many Sukhoi fighters. A Hero of the Soviet Union, he retired with the rank of major general.

The Sukhoi T-43-1 was the prototype for the Su-9 all-weather interceptor, a single-place, single-engine Mach 2+ fighter. It was built from the first pre-production Sukhoi T-3, with a new nose section and enlarged rear fuselage to accommodate a larger engine.

The production Su-9 is similar in appearance to the Mikoyan Gurevich MiG-21, but is much larger and heavier. It is 17.37 meters (56.99 feet) long with a wingspan of 8.43 meters (27.66 feet) and overall height of 4.88 meters (16.01 feet). The interceptor’s empty weight is 8,620 kilograms (19,004 pounds), and the maximum takeoff weight is 13,500 kilograms (29,762 pounds).

Both the T-43-1 prototype and the production Su-9 are powered by a Lyulka AL-7 nine-stage axial flow turbojet engine which produces 22,050 pounds of thrust with afterburner.

The Su-9 has a maximum speed of Mach 2.0 (2,135 kilometers per hour, 1,327 miles per hour). The service ceiling is 16,760 meters (54,987 feet) and range is 1,125 kilometers (699 miles).

The T-43-1 later set FAI records for sustained altitude and speed over a measured course.

The hydrogen balloon Örnen (Eagle) on the polar ice cap, 14 July 1897. (Nils Strindberg)

14 July 1897: At 8:11 p.m., G.M.T., the Andrée Arctic Expedition’s hydrogen gas balloon, Örnen (Eagle), came to rest on an ice floe in the Arctic Ocean, at N. 82° 52′, E. 29° 32′. ¹ This was the end of a planned transpolar flight and the beginning of a three-month struggle for survival.

At 1:50 p.m., 11 July 1897, Örnen rose from its protective enclosure on Danskøya (Danes Island) in the Svalbard Archipelago of Norway. Carried aloft in the balloon’s gondola were the expedition’s leader, Salomon August Andrée, and his fellow explorers, Knut Hjakmar Ferdinand Frænkel and Nils Strindberg.

The goal of the expedition was to fly across the North Pole and onward to Alaska on the North American Continent. Andrée considered that the balloon would need to retain enough gas during the voyage to remain airborne for 30 days. Supplies for the three men for that period were carried. 36 homing pigeons would allow the explorers to report their progress to the outside world.

This would be the expedition’s second attempt. The previous year, adverse winds forced the aeronauts to abandon the flight.

Henri Lachambre

Örnen had been designed and manufactured by Henri Lachambre at his balloon factory at Vaugirard, a suburb on the Left Bank of the Seine, Paris, France. The envelope was assembled from approximately 3,360 pieces of a thin woven Chinese silk fabric called pongee, stitched by hand. The seams were covered by glued strips of pongee. The upper two-thirds of the gas bag had three layers of fabric, while the lower one-third had two plies. It is estimated that 8 million stitches were required. Once completed, the envelope was covered with varnish.

The gondola was constructed of wood and wicker. It had an upper, observation, deck, and an enclosed lower sleeping quarters/darkroom.

A net made of more than 300 hemp ropes covered the balloon, and were braided into twelve ropes which were attached to a lifting ring. The gondola was suspended below this. At Sea Level, the inflated balloon with its gondola were approximately 97 feet (29.6 meters) high, and 68 feet (20.7 meters) in diameter. Its total volume is estimated at 4,800 cubic meters (approximately 170,000 cubic feet).

Buoyancy was provided by hydrogen gas which was produced on site at Danskøya. Hydrogen is the lightest element, and gaseous hydrogen has just 7% of the density of air. This provides greater buoyancy for lighter-than-air vehicles than other gases, but hydrogen gas molecules are also the smallest and they diffuse through fabric barriers more easily than any other gas. (Tests before Örnen was launched found that the balloon was losing about 35 cubic meters/1,236 cubic feet of hydrogen each day.)

Balloons have a disadvantage in that they go where the wind takes them. They are not steerable like dirigibles. So, steady southerly winds would be needed to carry Örnen to the North Pole, and northerly winds to travel from there to Alaska. Andrée had a theory that he believed would allow him to steer his balloon as much as 30° to either side of the prevailing wind.

Andrée’s idea was that if several long, heavy ropes were dragged behind the balloon, their weight and friction would cause the balloon to travel slower than the wind was blowing. He could then use two small sails to steer.

Örnen with guide ropes dragging in the water.

Also, these ropes could be used to control the balloon’s altitude. By pulling the ropes in, the weight supported by the balloon would increase, and it would descend. Letting more rope out would mean that the extra weight would be transferred to the surface, and the balloon would rise.

Altitude was critical. Andrée planned to maintain about 150 meters (approximately 500 feet). As the balloon ascended, atmospheric pressure on the envelope decreased. The pressure differential between the atmosphere and the hydrogen would increase, forcing the hydrogen to pass through the envelope more quickly. Any hydrogen loss was permanent, and the balloon’s buoyancy would decrease.

Balloon Örnen airborne, around 2:00 p.m., 11 July 1897. The wake of the steering ropes can be seen on the surface of the sea. (Andréemuseet, Griänna, Sweden)

Problems began immediately. As the guide ropes dragged through the water, they became heavier. They pulled the balloon down to the surface and the gondola actually touched the water. The aeronauts frantically began dumping ballast. Three of the four ropes became entangled and were pulled loose. Örnen began to rise again, but having lost ballast and the weight of the three guide ropes, it climbed to about 1,600 feet (490 meters). The loss of hydrogen accelerated.

The Eagle floated northward above a fog bank. It sank into the fog and sunlight shining on the envelope decreased. The balloon cooled and the gas inside began to contract. Buoancy decreased and the balloon sank further into the fog.

An alternating pattern of rising and falling developed. After the explorers passed into the Arctic ice pack, the gondola would alternately bounce across the broken ice, then rise again into the sky. At about 10:00 p.m., July 12, the gondola settled on to the ice and remained there for the next thirteen hours.

At 10:55 a.m., 13 July, once again airborne, the balloon continued on its flight. Drizzle and fog caused ice to form on the envelope. The gondola dragged behind. After jettisoning hundreds of pounds of ballast and equipment, Örnen rose higher, but again settled toward the ice. The remaining guide rope was lost. Realizing that the end of the flight was inevitable, the crew opened to valves to release the hydrogen. The balloon settled to the ice, and at 8:11 p.m., 14 July 1897, the crew climbed down from the gondola onto the ice floe.

Örnen on the arctic ice, 14 July 1897 (Nils Strindberg)

The total elapsed time of the journey was 65 hours, 35 minutes. In that time, Andrée, Frænkel and Strindberg had traveled 295 miles (475 kilometers) from their starting point on Danskøya.

The next three months were a courageous battle for survival as the three explorers tried to make their way back to civilization. They reached Kvitøya (White Island), an ice-covered island at the northeast of the Svalbard Archipelago. Andrée’s final journal entry was made on 17 October.

The bodies of the three men were discovered in 1930. Their remains were taken to Sweden.

There is much speculation as to the cause of their deaths, ranging from exposure, exhaustion, illness, suicide, or bear attack.

Track of the 1897 Andrée Arctic Expedition.

The expedition left behind journals with detailed meteorological data and other observations. More than 200 photographic images were left on film negatives protected in metal canisters.

The 1897 Andrée Arctic Expedition is the subject of books, newspaper and magazine articles, at least one motion picture, as well as many Internet articles of varying detail. The images taken by Nils Strindberg are available on the Internet and tell of their experiences.

13 July 1919

Airship R 34 over Pulham Airship Station, Norfolk, United Kingdom, 1919.

13 July 1919: The Royal Air Force rigid airship R 34 completed its two-way crossing of the Atlantic Ocean and at 6:57 a.m. landed at Pulham Airship Station, Norfolk, United Kingdom. The airship was under the command of Major George Herbert Scott, A.F.C., R.A.F. The total complement, including passengers, was 30 persons.

The return flight from Mineola, Long Island, New York took 73 hours, 3 minutes. According to records of the Fédération Aéronautique Internationale, the distance flown by R 34 on the return flight was 6,138 kilometers (3,814 miles).

This was the first “double crossing” by an aircraft. The round trip flight began at East Fortune Airship Station near Edinburgh, Scotland, on 2 July. The East-to-West crossing took 108 hours, 12 minutes.

Major Scott was appointed Commander of the Most Excellent Order of the British Empire.

This map shows the outbound and return tracks of His Majesty's Airship R 34, 2–13 July 1919.
This map shows the outbound and return tracks of His Majesty’s Airship R 34, 2–13 July 1919.

During the return flight on of the airship’s five engines suffered a broken connecting rod which damaged the cylinder block. It could not be repaired.

R 34 was based on extensive study of the captured German Zeppelin, L-33. It was built for the Royal Naval Air Service by William Beardmore and Company, Inchinnan, Renfrewshire, Scotland, but with the end of World War I, the RNAS and Royal Flying Corps were merged to become the Royal Air Force. 643 feet long (196 meters), with a maximum diameter of 78 feet, 9 inches (24 meters), the dirigible had a total volume of 1,950,000 cubic feet (55,218 cubic meters). The airship had a light weight metal structure covered with doped fabric. Buoyancy was provided by 55,185 cubic meters (1,948,840 cubic feet) of gaseous hydrogen contained in 19 gas bags inside the airship’s envelope. R 34 had a gross lift capacity of 59 tons. Useful lift was 58,240 pounds (26,417 kilograms).

The airship was powered by five water-cooled, normally-aspirated, 15.395-liter (989.483-cubic-inch-displacement) Sunbeam Maori Mk.IV dual overhead cam (DOHC) 60° V-12 engines with four valves per cylinder. The Mk.IV’s cylinder bore had been increased from 100 millimeters to 110 millimeters (3.94 to 4.33 inches), resulting in a larger displacement than previous Maori variants. The Maori Mk.IV was a direct-drive engine which produced 275 horsepower at 2,000 r.p.m. Each engine turned a two-bladed, 17 foot diameter (5.182 meter) propellers through a remote gearbox with a 0.257:1 reduction. The two wing engines were equipped with reversible gearboxes. With the engines turning 1,800 r.p.m., the R 34 had a cruising speed of 47 knots (54 miles per hour/87 kilometers per hour) and consumed 65 gallons (246 liters) of fuel per hour.

Louise Thaden with the Porterfield Model 35-W. (FAI)

12 July 1936: Louise Thaden set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over 100 Kilometers with an average speed of 176.35 kilometers per hour (109.58 miles per hour.)¹ She flew a Porterfield Model 35-W Flyabout over a course at Endless Caverns, near New Market, Virginia.

Less than two months later, 4 September 1936, Mrs. Thaden became he first woman to win the Bendix Trophy Race when she and her co-pilot, Blanche Noyes, flew a Beechcraft C17R “Staggerwing,” NR15835, from Floyd Bennett Field, Brooklyn, New York, to Mines Field, Los Angeles, California.

Harmon Aviatrix Trophy (NASM)

She was awarded the Harmon Aviatrix Trophy for 1936.

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 Wilbur Wright, 16 May 1928. In 1929, she was issued Transport Pilot License number 1943 by the Department of Commerce. She 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.

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.

Louise Thaden flew this Porterfield Model 35-W to set a World Record for Speed, 12 July 1936. (FAI)

The Porterfield Model 35-W was based on the prototype Wyandotte Pup, which had been designed by Noel Ross Hockaday. The airplane was built by students of the aviation club of Wyandotte High School, Kansas City, Kansas.

Hockaday had previously been a designer for the American Eagle Aircraft Corporation and had designed that company’s Eaglet high-wing monoplane. Edward Everette Porterfield, Jr., the founder of American Eagle, was present when the Wyandotte Pup made its first flight. He bought the airplane and its production rights. American Eagle had gone out of business during the early years of The Depression, and a new company, Porterfield Aircraft Corporation, was formed to manufacture the airplane as the Porterfield Model 35.

The Porterfield Model 35 Flyabout was produced in several variants, and was available with LeBlond, Velle, Warner or Continental engines. It was was a single-engine, high-wing monoplane, which carried a pilot and one passenger in tandem in an enclosed cabin. The airplane had fixed landing gear with a tail skid. The fuselage was a welded tube structure, while the wing was built around two spruce spars, with spruce and plywood ribs. The airplane was covered with doped fabric. A distinctive feature of the Porterfield series are the parallel wing struts. (Most similar aircraft have their struts arranged in a “V”.)

The Model 35-W was powered by an air-cooled, normally-aspirated, 301.458-cubic-inch-displacement (4.940 liter) Warner Aircraft Corporation Scarab Junior. This was a 5-cylinder radial engine with two valves per cylinder and a compression ratio of 5.2:1. The Scarab Junior was rated at 90 horsepower at 2,050 r.p.m. at Sea Level for takeoff (five-minute limit). The engine was 1 foot, 2 inches (0.356 meters) long, 3 feet, 0.5 inches (0.927 meters) in diameter, and weighed 237 pounds (107.5 kilograms). The engine was covered by a Townend Ring.

The 35-W had a cruise speed of 110 miles per hour (177 kilometers per hour) and maximum speed of 120 miles per hour (193 kilometers per hour). Its range was 340 miles (547 kilometers).

Porterfield Aircraft Corporation built approximately 240 Model 35s. Twenty-five of these were the Model 35-W.

Noel Ross Hockaday was born 24 May 1905 in Kinmundy, Illinois. He was the first of two children of Jake Fred Hockaday, a farmer, and Mary Kathryn Sills Hockaday. He married to Ruby I. Kelley at Los Angeles, 31 March 1937..

In addition to the Eaglet and Pup, Hockaday designed the Rearwin Airplanes Inc., Speedster, Sportster and Cloudster. (Rearwin, like Porterfield, was based at Fairfax Airport, Kansas City, Kansas.)

In 1940, Hockaday worked for the Lockheed Aircraft Corporation. Hockaday later formed Hockaday Aircraft Corporation at Burbank, California, to produce the Hockaday Comet.
