15 December 1959: At Edwards Air Force Base, California, Major Joseph William Rogers, United States Air Force, flew a Convair F-106A Delta Dart all-weather interceptor, serial number 56-0467, to a new Fédération Aéronautique Internationale (FAI) World Record for Speed over a 15 Kilometer-to-25 Kilometer Straight Course, breaking the record set two years earlier by Major Adrian E. Drew with a modified McDonnell F-101A Voodoo.¹

At an altitude of 40,000 feet (12,192 meters), Rogers made two passes over the straight 11 mile (17.7 kilometers) course, once in each direction, for an average speed of 2,455.736 kilometers per hour (1,525.924 miles per hour)—Mach 2.31. For his accomplishment, he was awarded the Distinguished Flying Cross, the FAI’s Henry De La Vaulx Medal, and the Thompson Trophy.

Major Rogers was the Air Force F-106 project officer assigned to Convair. He first attempted the record with another F-106A, 56-0459, but when that Delta Dart developed uncontrollable compressor stalls, 56-0467 was substituted. (This has led to confusion over which aircraft actually set the record, but in an interview, Colonel Rogers confirmed that it was 467.)

Joseph William Rogers was born at Chillicothe, Ohio, 28 May 1924. He grew up on a farm, and attended West High School, graduating in 1942. He enlisted in the U.S. Army Air Corps in 1943 and trained as a pilot. From 1944 he was assigned as a flight instructor in California. Rogers remained in the Air Force after World War II.

During the Korean War, Joe Rogers got the nickname “Whistlin’ Joe” when he put whistles on the wings of his North American Aviation F-51D Mustang in an effort to frighten enemy troops. 1st Lieutenant Rogers was awarded the Silver Star for his actions of 8 October 1950, in close support of a British infantry unit, which was surrounded on a hilltop by the enemy.

Though not officially credited, it is widely accepted that on 8 November 1950, with his Mustang Buckeye Blitz VI, he shot down an enemy Mikoyan-Gurevich MiG-15 jet fighter. An aerial victory of a piston-engine fighter over a jet fighter was a very rare occurrence. Rogers was one of a group of “The American Fighting Man” named Man of the Year by TIME Magazine. He flew 170 combat missions in the F-51 and another 30 in the Lockheed F-80 Shooting Star.

Rogers was a 1954 graduate of the Air Force Test Pilot School and worked as a test pilot on the North American Aviation F-86D Sabre radar-equipped interceptor, and then the Convair F-102 Delta Dagger and F-106 Delta Dart.

From 1960 to 1964 Rogers commanded the 317th Fighter Interceptor Squadron at Elmendorf Air Force Base, Alaska, which was, at that time, the largest squadron in the United States Air Force. In 1963, he flew a F-102 in the annual William Tell competition at Tyndall Air Force Base, Florida, which he won, and was named the Air Force’s “Top Gun.”

Next Rogers he commanded the Lockheed SR-71A and F-12A Test Force at Edwards Air Force Base. He is one of the few pilots to have ejected from an SR-71A, when 61-7953 went out of control, 18 December 1969. Both he and Radar Intercept Officer Lieutenant Colonel Gary Heidelbaugh safely escaped the doomed Blackbird.

Colonel Rogers was Vice Commander of the 3d Fighter Wing, flying the McDonnell F-4 Phantom II during the Vietnam War. After serving as Assistant Deputy Commander of the 7th and 13th Air Forces, he was appointed Chief of Staff for Operations at the Aerospace Defense Command Headquarters, Peterson Air Force Base, Colorado. Rogers retired from the Air Force in 1975 after 32 years of service.

Joe Rogers worked for Northrop Aerospace for the next 13 years, marketing the company’s F-5 and F-20 fighters.

During his service in World War II, the Korean War and the Vietnam War, Colonel Rogers was awarded the Silver Star, the Legion of Merit with two Oak Leaf Clusters, Distinguished Flying Cross with two Oak Leaf Clusters, and Air Medal with thirteen Oak Leaf Clusters.

Joe Rogers was married to the former Charis Tate. They had three children. Mrs. Rogers passed away in 2003.

Colonel Joseph W. Rogers died at Healdsburg, California, 6 August 2005, at the age of 81 years. He is buried at Arlington National Cemetery, alongside his wife.

The Convair F-106A Delta Dart was the primary all-weather interceptor of the United States Air Force from 1959 to 1988, when it was withdrawn from service with the Air National Guard. It was a single-seat, single engine delta-winged aircraft capable of speeds above Mach 2. The airplane was a development of the earlier F-102A Delta Dagger, and was initially designated F-102B. However, so many changes were made that it is considered to be a new aircraft.

The F-106A is 70 feet, 8¾ inches (21.558 meters) long with a wingspan of 38 feet, 4 inches (11.684 meters). The top of the vertical fin was 20 feet, 3¼ inches (6.179 meters) high. The Delta Dart weighs 24,646 pounds (11,179 kilograms) empty, 35,500 pounds (16,103 kilograms) gross, andhas a maximum takeoff weight (MTOW) of 41,831 pounds (18,974 kilograms).

The F-106 was powered by a Pratt & Whitney J75-P-17 afterburning turbojet engine. The J75-P-17 was a two-spool axial-flow turbojet engine with afterburner. It used a 15-stage compressor section (8 high- and 7 low-pressure stages) and a 3-stage turbine section (1 high- and 2-low pressure stages. The J75-P-17 was rated at 16,100 pounds of thrust (71.62 kilonewtons) 24,500 pounds (108.98 kilonewtons) with afterburner. The engine was 3 feet, 7.0 inches (1.092 meters) in diameter, and weighed 5,875 pounds (2,665 kilograms)

The interceptor has a cruise speed of 650 miles per hour (1,046 kilometers per hour). Major Joseph Rogers demonstrated the maximum speed of Mach 2.31 (1,525 miles per hour/2,454 kilometers per hour) at 40,000 feet (12,192 meters) during his record-breaking run. The F-106A had a service ceiling is 57,000 feet (17,374 meters) and a rate of climb of 29,000 feet per minute (150 meters per second). It had a combat radius of 575 miles (925 kilometers) and a maximum range of 1,809 miles (2,911 kilometers).

The Delta Dart was armed with four AIM-4 Falcon air-to-air guided missiles and one AIM-2A Genie unguided rocket with a 1.5 kiloton W25 nuclear warhead. In 1972, the General Electric M61 Vulcan 20mm cannon was added.

Convair built 342 F-106 interceptors. 277 were F-106As and the remainder were F-106B two-seat trainers.

F-106A 56-0467 was built in April 1958 and was the eighteenth production aircraft. After being used for flight testing at Edwards Air Force Base it was converted back to an operational interceptor and assigned to the 329th Tactical Fighter Squadron at nearby George Air Force Base.

On 14 August 1961, while taking off from George Air Force Base, Victorville, California, on a routine training mission, 56-0467’s right tire blew out. The pilot, James Wilkinson, flew until most of the airplane’s fuel had been exhausted, and then landed at Edwards Air Force Base because of its longer runway and available emergency equipment. After touching down, the right wheel and brake assembly caught fire. The flames quickly spread to the wing and fuselage. The aircraft slid to a stop and the pilot safely escaped. 467 was totally destroyed.

56-0459, which had been scheduled to make the speed record flights, is on display at the McChord Air Force Base Museum.

12 December 1957: Major Adrian Eason Drew, U.S. Air Force, commanding officer, 481st Fighter Bomber Squadron, 27th Fighter Bomber Wing, Tactical Air Command, set a new Fédération Aéronautique Internationale (FAI) absolute speed record over the 15/25 kilometer course at Edwards Air Force Base, California.¹ Major Drew flew a modified McDonnell F-101A-5-MC Voodoo, serial number 53-2426.

The Voodoo, the ninth production F-101A, had been bailed to Pratt & Whitney by the Air Force to test a new J57-P-55 afterburning turbojet engine intended for the F-101B Voodoo, and it was redesignated JF-101A. The new engine produced 16,000 pounds of thrust with afterburner. The modified aircraft had longer jet exhaust tubes, and air scoops were installed in the belly to provide additional cooling air for the afterburners.

At 39,000 feet (11,887 meters), Major Drew accelerated for 65 miles (105 kilometers) before entering the 10.1 statute mile (16.25 kilometers) course. He made one pass in each direction. Actual time on course, each way, was 29.8 seconds. The official average speed for the two passes is 1,943.5 kilometers per hour (1,207.64 miles per hour). Although the air temperature was -79 °F. (-62 °C.), frictional heating brought the Voodoo’s skin temperature to 190 °F. (88 °C.), high enough to blister the airplane’s paint.

Major Drew was awarded the Distinguished Flying Cross and the Thompson Trophy for 1957.

Adrian Eason Drew was born 8 October 1920 in Georgia, the first of six children of John Robert Drew, a farmer, and Ada Elma Eason Drew.

After one year of college, Adrian Drew enlisted as a private in the U.S. Army Air Corps, 31 March 1942, at Fort McClellan, Alabama. He was 5 feet, 8 inches (1.73 meters) tall and weighed 143 pounds (64.9 kilograms).

On 14 November 1942, Drew married Miss Sarah B. Kaylor in Pinellas County, Florida. They would have three daughters, Nancy, Bonnie and Jo Anne.

Colonel Drew was a combat pilot during World War II, the Korean War and the Vietnam War. He commanded the 309th Strategic Fighter Squadron from January to October 1955, flying the Republic F-84 Thunderjet. In August 1957, he became the first commanding officer of the 481st Fighter Bomber Squadron at Bergstom Air Force Base,  Austin, Texas. Lieutenant Colonel Drew commanded the 354th Tactical Fighter Squadron at George Air Force Base, California, from 1962 to 1964, flying the Republic F-105D Thunderchief, and briefly commanded the 355th Tactical Fighter Wing.

Two weeks before a scheduled promotion to Brigadier General, Colonel Drew suffered a major heart attack and was forced to retire from the Air Force. He died 27 July 1985 at the age of 64 years. He was buried at Shawnee View Gardens Cemetery, Cumming, Georgia.

The McDonnell F-101 Voodoo was originally designed as a single-seat, twin-engine long range bomber escort, or “penetration fighter” for the Strategic Air Command, but was developed as a fighter bomber and reconnaissance airplane. The Voodoo first flew 29 September 1954, and the first F-101A was delivered to the Air Force 2 May 1957.

The F-101A was 67 feet, 5 inches (20.549 meters) long with a wingspan of 39 feet, 8 inches (12.090 meters). It was 18 feet (5.486 meters) high. The Voodoo weighed 24,970 pounds (11,245 kilograms) empty and had a maximum takeoff weight of 50,000 pounds (22,680 kilograms).

The standard F-101A was equipped with two Pratt and Whitney J57-P-13 afterburning turbojet engines. The J57 was a two-spool axial-flow turbojet which had a 16-stage compressor (9 low- and 7 high-pressure stages), and a 3-stage turbine (1 high- and 2 low-pressure stages). The J57-P-13 was rated at 10,200 pounds of thrust (45.37, and 15,800 pounds (70.28 kilonewtons) with afterburner.

The J57-P-55 engines installed in the JF-101A were rated at 10,700 pounds of thrust (49.60 kilonewtons), and 16,900 pounds (75.18 kilonewtons) with afterburner. They were 20 feet,  11.93 inches (6.399 meters) long, 3 feet, 4.5 inches (1.029 meters) in diameter, and weighed 5,215 pounds (2,365 kilograms).

The maximum speed of the F-101A was 1,009 miles per hour (1,624 kilometers per hour) at 35,000 feet (10,668 meters). Its service ceiling was 55,800 feet (17,008 meters). It carried 2,341 gallons (8,862 liters) of fuel internally. With external tanks, the fighter bomber had a maximum range of 2,925 miles (4,707.3 kilometers).

The F-101A was armed with four 20mm Pontiac M39 single-barreled revolver cannon, with 200 rounds per gun. It could carry a Mark 28 bomb on a centerline mount.

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 II, 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

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. 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. 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. It 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.

For his effort to save a valuable research aircraft, Peter Twiss was awarded the Queen’s Commendation for Valuable Service in the Air. Notice of the award was published in The London Gazette, 22 February 1955, at Page 1094:

Lionel Peter Twiss, Test Pilot, Fairey Aviation Company Ltd. (Hillingdon, Middlesex.)

     For services when an aircraft, undergoing tests, sustained damage in the air.

On 10 March 1956, Phillip 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, USAF, flying a North American Aviation F-100C Super Sabre over Edwards Air Force Base, California. (FAI Record File # 8867)

Peter Twiss was the first British pilot, and the FD.2 the first British airplane, to exceed 1,000 miles per hour (1,609 kilometers per hour) in level flight. Twiss is also the last British pilot to have held a World Absolute Speed Record.

For his services as a test pilot, Lieutenant-Commander Lionel Peter Twiss, D.F.C. and Bar, was appointed Officer of the Most Excellent Order of the British Empire, 13 June 1957.

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.

Lionel Peter Twiss was born 23 July 1921 at Lindfield, Sussex, England. He was educated at the Sherborne School, a prestigious boarding school for boys, in Dorset. He briefly worked as a tea taster following school, but in 1939 enlisted in the Royal Navy Fleet Air Arm. He was trained as a fighter pilot.

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 from HMS Argus (I49) in support of Malta in the Mediterranean Sea. Twiss is credited with shooting down one enemy fighter and damaging a bomber. He was awarded the Distinguished Flying Cross, 22 September 1942. He and his squadron transitioned to the Supermarine Seafire aboard HMS Furious (49) and were in action during the invasion of North Africa. He was awarded a Bar, denoting a second award, to his D.F.C.

After returning to England in 1943, Twiss was trained as a night fighter pilot and 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.

Twiss was in the third class of the Empire Test Pilots’ School and after graduation was assigned to Fairey Aviation. With the end of World War II, Lieutenant-Commander Twiss left the Royal Navy and continued working as a test pilot at Fairey.

Peter Twiss ended his career testing aircraft in 1959, having flown more than 4,500 hours in nearly 150 different aircraft. His autobiography, Faster than the Sun, was published in 1963.

Lieutenant-Commander Lionel Peter Twiss, O.B.E., D.F.C. and Bar, died 31 August 2011 at the age of 90 years.

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.

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.
