22 November 1961: In recognition of the 50th Anniversary of Naval Aviation, a number of speed and altitude record attempts were planned, using the U.S. Navy’s new McDonnell YF4H-1 Phantom II fighter. On the morning of 22 November, Lieutenant Colonel Robert Bradford Robinson, Jr., United States Marine Corps, took off from Edwards Air Force Base on Operation Skyburner, an attempt to set a new World Absolute Speed Record. He was flying the second Phantom II built, Bu. No. 142260.
The Phantom carried three external fuel tanks for this flight. It had a 600-gallon (2,271.25 liter) centerline tank and two 370-gallon (1,400.6 liter) wing tanks. Robinson flew southeast toward NAS El Centro, then turned back to the northwest. Over the Salton Sea, he began to accelerate the YF4H-1 to build up speed for the record run over a measured twenty-mile course back at Edwards AFB. The Phantom’s two General Electric J79-GE-3A afterburning turbojets used a tremendous amount of fuel at full throttle and the centerline fuel tank was quickly emptied. Robinson jettisoned the empty tank over the Chocolate Mountain gunnery range. Continuing to accelerate, the two wing tanks were next jettisoned as they ran dry, this time at Bristol Dry Lake.

The Phantom entered the east end of the speed course in full afterburner. Having burned off more than 1,300 gallons of fuel, 142260 was much lighter now, and aerodynamically cleaner after dropping the external tanks. Robinson exited the west end of the 20-mile (32.2 kilometer) course in less than one minute.
Fédération Aéronautique Internationale rules require that a speed record must be made with two passes in opposite directions. The average speed of the two runs is the record speed. The Phantom was flying so fast that it covered another 105 miles (169 kilometers) before it could turn around. During the turn, it was still traveling at 0.9 Mach.
Robinson again put the engines in afterburner as he approached the course from the west. On the second run, the fighter was even lighter and its recorded speed was more than 1,700 miles per hour (2,736 kilometers per hour). The average of the two runs was calculated at 2,585.425 kilometers per hour (1,606.509 miles per hour.) This was the new FAI Absolute World Speed Record.¹
For his accomplishment, Lieutenant Colonel Robinson was awarded the Distinguished Flying Cross by Secretary of the Navy John B. Connally. The presentation took place on 25 November 1961 at Newport News, Virginia, during the commissioning of USS Enterprise CVA(N)-65.

In the next few weeks, the same YF4H-1 would establish a world record for sustained altitude—20,252 meters (66,444 feet).² Two years earlier, 6 December 1959, in Operation Top Flight, 142260 had established a world record for absolute altitude when it zoom-climbed to 98,557 feet (30,040 meters).³

17 November 1954: Lionel Peter Twiss, Chief Test Pilot for Fairey Aviation Company Ltd., was flying the company’s experimental supersonic airplane, the Fairey Delta 2, WG774, from the aircraft test center at RAF Boscombe Down, Salisbury, Wiltshire, England. This was the FD.2’s fourteenth flight.
When about 30 miles (48 kilometers) from the airfield and climbing through 30,000 feet (9,144 meters), the airplane’s fuel supply was interrupted and the engine flamed out.
Unwilling to lose a valuable research aircraft, Twiss decided to stay with the Delta 2 rather than ejecting, and he glided back to Boscombe Down, descending through a layer of cloud at 2,500 feet (762 meters). Without the engine running, the aircraft had insufficient hydraulic pressure to completely lower the landing gear and only the nosewheel strut locked in place. The FD.2 touched down at 170 miles per hour (274 kilometers per hour) and was seriously damaged.
WG774 was out of service for nearly a year. The wings had to be replaced and those which had originally been built for structural tests were used.

On 10 March 1956, Peter Twiss flew WG774 to set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 15km/25km Straight Course at an average speed over a 9-mile course, flown between Chichester and Portsmouth at and altitude of 38,000 feet (11,582 meters). Two runs over the course were made, with first averaging 1,117 miles per hour (1,798 kilometers per hour) and the second, in the opposite direction, was 1,147 miles per hour. (1,846 kilometers per hour). The FD.2 had averaged 1,822 Kilometers per hour (1,132 miles per hour)—Mach 1.731. ¹
Twiss had broken the previous record of 1,323.312 kilometers per hour (822.268 miles per hour) which had been set by Colonel Horace A. Hanes, U.S.Air Force, flying a North American Aviation F-100C Super Sabre over Edwards Air Force Base, California. ²

The Fairey Aviation Company, Ltd., Delta 2 WG774 (c/n F9421) is the first of two single-place, single-engine delta-wing research aircraft which had been designed and built to investigate transonic and supersonic speeds. It first flew 6 October 1953 with Chief Test Pilot Peter Twiss in the cockpit.
In its original configuration, the FD.2 is 51 feet, 7½ inches (15.735 meters) long with a wingspan of 26 feet, 10 inches (8.179 meters) and overall height of 11 feet (3.353 meters). The wings’ leading edge were swept to 59.9° with an angle of incidence of +1.5°. Ailerons and flaps were at the trailing edge and acted in place of elevators. In its original configuration it had an empty weight of approximately 11,000 pounds (4,990 kilograms) and the all-up weight at takeoff was 14,109 pounds (6,400 kilograms).
The FD.2 was powered by a Rolls-Royce Avon RA.28R afterburning turbojet engine which produced 9,530 pounds of thrust (42.392 kilonewtons), or 11,820 pounds (52.578 kilonewtons) with afterburner (“reheat”). This was a single-shaft axial-flow turbojet with a 15-stage compressor and 2-stage turbine. The RA.28 was 10 feet, 3.0 inches (3.124 meters) long, 3 feet, 5.5 inches (1.054 meters) in diameter, and weighed 2,869 pounds (1,301 kilograms).
WG774 and its sistership, WG777, were used for flight testing throughout the 1960s. WG774 was modified as a test aircraft to study various features of the planned British Aerospace Concorde. The landing gear struts were lengthened and the fuselage extended by six feet. It received a “drooped” nose section for improved pilot visibility during takeoff and landings. New wings were installed which had an ogee-curved leading edge. With these modifications WG774 was redesignated BAC 221. In this configuration, WG774 was tested to Mach 1.65 at 40,000 feet (12,192 meters).
WG774 was retired in the early 1970s. It is on display at the Fleet Air Arm Museum, Yeovilton, Somerset, England.

Temporary Sub-Lieutenant (A) Lionel Peter Twiss, R.N.V.R., was assigned as the pilot of a Hawker Hurricane Mk.I with the Merchant Ship Fighter Unit. (Hurricanes could be launched by catapult from merchant ships to defend against Luftwaffe Focke-Wulf Fw 200 Condor reconnaissance bombers.)
He next flew the Fairey Fulmar fighter with No. 807 Squadron from HMS Argus (I49), in support of Malta in the Mediterranean Sea. Sub-Lieutenant Twiss is credited with shooting down one enemy fighter and damaging a bomber. He was awarded the Distinguished Service Cross, 22 September 1942. He and his squadron transitioned to the Supermarine Seafire aboard HMS Furious (47) and were in action during the invasion of North Africa. He was awarded a Bar, denoting a second award, to his D.S.C., 16 March 1943.
Sub-Lieutenant Twiss, D.S.C. and Bar, was promoted to the rank of Temporary Lieutenant, 17 August 1943. After returning to England, Twiss was trained as a night fighter pilot. He flew the de Havilland DH.98 Mosquito with an RAF night fighter unit on intruder missions over France. In 1944 he shot down two more enemy airplanes.
Later in 1944, Twiss was sent to the United States to work with the British Air Commission. In this position, he was able to fly various U.S. fighter aircraft, including the turbojet-powered Bell P-59 Airacomet.
Lieutenant-Commander Twiss was in the third class of the Empire Test Pilots’ School and after graduation he was assigned to Fairey Aviation for duty as a test pilot.
With the end of World War II, Lieutenant-Commander Twiss left the Royal Navy and continued working as a civilian test pilot at Fairey. He became to the company’s chief test pilot in 1954.

31 October 1959: At Joukovski-Petrovskoe, U.S.S.R., Гео́ргий Константи́нович Мосоло́в (Georgy Konstantinovich Mosolov), chief test pilot for Mikoyan-Gurevich, flew a prototype of the MiG-21 interceptor identified as the E-66, to set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 15/25 Kilometer Straight Course. His speed averaged 2,388 kilometers per hour (1,483.8 miles per hour).¹
The МиГ-21 prototype identified by the symbol E-66 is known at the Mikoyan Design Bureau as the E-6\3. Its first flight took place in December 1958. It is powered by a Tumansky 11F-300 afterburning turbojet engine. (A Wikipedia article suggests that this airplane was rebuilt to different configurations several times, with designations changed accordingly.)
Mosolov’s FAI altitude record of 28 April 1961 was also flown in a MiG-21 prototype called E-66. (FAI Record File # 8661) Photographs and motion picture film of that airplane show it marked with red numerals “31” on the forward fuselage.
The airplane in this photograph from the web site “Wings of Russia” is described as showing the Mikoyan-Gurevich E-6T\1 prototype, “31 Red,” flown to a world record altitude by Colonel Mosolov, 28 April 1961.
Colonel Mosolov was interviewed for an article in Air & Space Smithsonian Magazine. He told writer Tony Reichhardt that after completing the speed record course, he was 125 miles (201 kilometers) from base at 44,000 feet (13,411 meters). Low on fuel, he shut down the turbojet engine and began a long glide. He twice unsuccessfully attempted to restart the engine for the landing, but was forced to glide all the way to the runway. After landing, the fuel system was drained. Only 8 liters (2.1 gallons) remained.

Georgy Konstantinovich Mosolov was born 3 May 1926 at Ufa, Bashkortostan, Union of Soviet Socialist Republics. He was educated at the Central Aviation Club, where he graduated in 1943, and then went to the Special Air Forces School. In 1945 he completed the Primary Pilot School and was an instructor at the Chuguev Military Aviation School (Kharkiv, Ukraine). In 1953 Mosolov was sent to the Ministry of Industrial Aviation Test Pilot School at Ramenskoye Airport, southeast of Moscow, and 6 years later, to the Moscow Aviation Institute. He was a test pilot at the Mikoyan Experimental Design Bureau from 1953 to 1959, when he became the chief test pilot.
Georgy Mosolov set six world speed and altitude records. He was named a Hero of the Soviet Union, 5 October 1960.
On 11 September 1962, an aircraft that Colonel Mosolov was flying suffered a catastrophic compressor failure at Mach 2.15 and began to break apart. Severely injured, Mosolov ejected from the doomed airplane at Mach 1.78. He survived but his test flying career was over. His recovery took more than a year, and though he was able to fly again, he could not resume his duties as a test pilot.
This Mikoyan-Gurevich E-152A, NATO code name “Flipper,” is one of the many MiG-21 prototypes flown by Georgy Mosolov.

29 October 1953: Lieutenant Colonel Frank Kendall (“Pete”) Everest, United States Air Force, flew a new prototype air superiority fighter, North American Aviation’s YF-100A Super Sabre, serial number 52-5754, over the 3 kilometer and 15 kilometer courses at the Salton Sea, in the Colorado Desert of southeastern California.
Flying four runs over the short course, Everest averaged 757.75 miles per hour (1,219.48 kilometers per hour). Although this was 4.80 miles per hour (7.725 kilometers per hour) faster than the FAI record set three weeks earlier by Lieutenant Commander James B. Verdin, U.S. Navy, with a Douglas XA4D-1 Skyray,¹ it was not fast enough to establish a new world record under FAI rules, which required that a new record exceed the previous record by 1%.

Next came four speed runs over the 15/25 kilometer course. All runs were made with the Super Sabre flying within 100 feet (30 meters) of the ground. The official Fédération Aéronautique Internationale (FAI) average speed was 1,215.298 kilometers per hour (755.151 miles per hour)—0.99 Mach. ²
The course at the Salton Sea was used because its surface lies 235 feet (72 meters) below Sea Level. The denser air causes undesired transonic effects to occur at lower speeds, but the higher air temperatures help to delay them, allowing the pilot a greater margin of control during the speed record runs.

Frank Kendall (“Pete”) Everest, Jr., was born 10 Aug 1920, at Fairmont, Marion County, West Virginia. He was the first of two children of Frank Kendall Everest, an electrical contractor, and Phyllis Gail Walker Everest. Attended Fairmont Senior High School, Fairmont, West Virginia, graduating in 1939. He studied at Fairmont State Teachers College, also in Fairmont, West Virginia, and then studied engineering at the University of West Virginia in Morgantown.
Pete Everest enlisted as an aviation cadet in the United States Army Air Corps at Fort Hayes, Columbus, Ohio, 7 November 1941, shortly before the United States entered World War II. His enlistment records indicate that he was 5 feet, 7 inches (1.703 meters) tall and weighed 132 pounds (59.9 kilograms). He graduated from pilot training and was commissioned as a second lieutenant, Air Reserve, 3 July 1942.

In 1944, Everest was returned to the United States to serve as a flight instructor. He requested a return to combat and was then sent to the China-Burma-India theater of operations where he flew 67 missions and shot down four Japanese airplanes. Everest was appointed commanding officer of the 29th Fighter Squadron (Provisional), 5th Fighter Group (Provisional) at Chihkiang, China, in April 1945. He was himself shot down by ground fire in May 1945. Everest was captured by the Japanese and suffered torture and inhumane conditions before being freed at the end of the war. He was promoted to the rank of major, 1 July 1945. He was returned to the United States military 3 October 1945.
Following World War II, Major Everest was assigned as a test pilot at Wright-Patterson Air Force Base, Ohio, before going west to the Air Force Flight Test Center at Edwards Air Force Base, California.
Major Everest was returned to the permanent rank of first lieutenant, Air Corps, 19 June 1947, with date of rank retroactive to 3 July 1945.
At Edwards, Pete Everest was involved in nearly every flight test program, flying the F-88, F-92, F-100, F-101, F-102, F-104 and F-105 fighters, the XB-51, YB-52, B-57 and B-66 bombers. He also flew the pure research aircraft, the “X planes:” the X-1, X-1B, X-2, X-3, X-4 and X-5. Pete Everest flew the X-1B to Mach 2.3, and he set a world speed record with the X-2 at Mach 2.9 (1,957 miles per hour, 3,149.5 kilometers per hour) which earned him the title, “The Fastest Man Alive.” He was the test pilot on thirteen of the twenty X-2 flights.
In 1957, Lieutenant Colonel Everest was awarded the Harmon Trophy “for the most outstanding international achievements in the arts and/or science of aeronautics for the preceding year,” and also received the Octave Chanute Award “for an outstanding contribution made by a pilot to the art, science and technology of aeronautics.”

The North American Aviation F-100 Super Sabre was designed as a supersonic day fighter. Initially intended as an improved F-86D and F-86E, the “Sabre 45” soon developed into an almost completely new airplane.
The Super Sabre had a 49° 2′ sweep to the leading edges of the wings and horizontal stabilizer. The total wing area was 385.2 square feet (35.79 square meters). The wings had an angle of incidence of 0°, with no twist or dihedral. The ailerons were placed inboard on the wings and there were no flaps, resulting in a high stall speed in landing configuration. The horizontal stabilizer was moved to the bottom of the fuselage to keep it out of the turbulence created by the wings at high angles of attack. The F-100A had a distinctively shorter vertical fin than the YF-100A. The upper segment of the vertical fin was swept 49° 43′.
There were two service test prototypes, designated YF-100A, followed by the production F-100A series. The first ten production aircraft (all of the Block 1 variants) were used in the flight testing program.
The F-100A Super Sabre was 47 feet, 1¼ inches (14.357 meters) long with a wingspan of 36 feet, 6 inches (11.125 meters). With the shorter vertical fin, the initial F-100As had an overall height of 13 feet, 4 inches (4.064 meters), 11 inches (27.9 centimeters) less than the YF-100A.

The F-100A had an empty weight of 18,135 pounds (8,226 kilograms), and its maximum takeoff weight was 28,971 pounds (13,141 kilograms). It had an internal fuel capacity of 744 gallons (2,816 liters) and could carry two 275 gallon (1,041 liter) external fuel tanks.
The new air superiority fighter was powered by a Pratt & Whitney Turbo Wasp J57-P-7 engine. The J57 was a two-spool axial-flow turbojet which had a 16-stage compressor section (9 low- and 7 high-pressure stages) and a 3-stage turbine (2 high- and 1 low-pressure stages). Its continuous power rating was 8,000 pounds of thrust (35.586 kilonewtons). The Military Power rating was 9,700 pounds (43.148 kilonewtons) (30-minute limit). Maximum power was 14,800 pounds (43.148 kilonewtons) with afterburner (5-minute limit). The engine was 20 feet, 9.7 inches (6.342 meters) long, 3 feet, 3.9 inches (1.014 meters) in diameter, and weighed 5,075 pounds (2,303 kilograms). Later production aircraft used a J57-P-39 engine, which had the same ratings.

2 September 1953: Colonel J. Stanley Holtoner, U.S. Air Force, flew a production North American Aviation F-86D-35-NA Sabre, serial number 51-6168, to a Fédération Aéronautique Internationale (FAI) World Speed Record over a 100 kilometer course at Vandalia, Ohio, averaging 1,110.75 kilometers per hour (690.188 miles per hour).¹ Colonel Holtoner was the commanding officer of the Air Force Flight Test Center, Edwards Air Force Base, California. He was awarded the Thompson Trophy.
On the previous day, Captain Harold E. Collins flew another F-86D Sabre, 51-6145, setting an FAI World Speed Record over a 15 kilometer straight course of 1,139.219 kilometers per hour (707.878 miles per hour).²

The The North American Aviation, Inc. F-86D Sabre was an all-weather interceptor developed from North American Aviation F-86 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 search radar and armed with twenty-four unguided 2.75-inch (69.85 millimeter) Mk 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 longer and wider fuselage. It was also considerably heavier. The day fighter’s sliding canopy was replaced with a hinged “clamshell” canopy. A large, streamlined radome was above the reshaped engine intake.
The F-86D Sabre was 40 feet, 3¼ inches (12.275 meters) long with a wingspan of 37 feet, 1½ inches (11.316 meters), and overal height of 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.
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, F-86D 51-6168 was transferred to the Greek Air Force. In 2009, it was photographed, stripped and sitting on its belly, at Agrinion Airport (AGQ), Greece.
