26 July 1937: Jackie Cochran set a United States Women’s National Speed Record ¹ of 203.895 miles per hour (328.137 kilometers per hour) over a 1,000 kilometer (621.4 mile) course between the Union Air Terminal at Burbank, California, and San Francisco’s Golden Gate Bridge, and return, flying a Beechcraft D17W “Staggerwing,” NX17081, serial number 136. ²

A woman in the air, therefore, had a choice of flying around in a light plane for pleasure or of obtaining for herself new fast and experimental equipment and determining the maximum that could be obtained from its use. I followed the second course. The objective of each flight was to go faster through the atmosphere or higher into it than anyone else and to bring back some new information about plane, engine, fuel, instruments, air or pilot that would be helpful in the conquest of the atmosphere.

The Oakland Tribune reported:

WOMAN MAKES SPEED FLIGHT

Coast Record May have been Set on Oakland-L.A. Hop

     Jacqueline Cochrane[sic]Odlum, wife of a wealthy New York investment broker, today claimed a non-stop speed record for women fliers between Los Angeles and Oakland.

     The 27-year-old aviatrix made the round trip between Union Air terminal and Oakland yesterday in 3 hours 2 minutes and 51 seconds, averaging 203.89 miles per hour.

     While no official record now exists for a women’s flight over the 621.37 mile distance, Mrs. Odlum said she will seek recognition of her mark by the National Aeronautic Association and the Federation Aeronautique Internationale.

     Mrs. Odlum probably will enter her cabin racing plane, equipped with a 600-horsepower engine, in the Bendix races in September. She has been in the Bendix races before, and, in 1934, was in the London-to-Australia air derby but abandoned her hop in Bucharest.

     Floyd Odlum, to whom the aviatrix was married last year, is eminent in the world of finance and is known as the man who built the Atlas Corporation into one of the most successful investment trusts.

199 M.P.H. RECORD SET BY AVIATRIX

Jacqueline Odlum Establishes Second Flying Mark

     BURBANK, Calif., July 29—(I.N.S.)—Another women’s flying record—her second in a week—was hung up by Jacqueline Cochran Odlum, pretty aviatrix, timekeepers at the Los Angeles airport here announced today.

     Mrs. Odlum flew to Garden Grove, Cal., and back to set a new 100-kilometer speed record for women of 199 miles an hour. The previous record was held by Mrs. Louise Thaden, who did it at 196 miles and hour.

     A week ago [sic] Mrs. Odlum flew to San Francisco and back at 203.89 miles an hour to set an average speed record for 1,000 kilometers.

NC17081 was one of two special D17W biplanes that were built by the Beech Aircraft Corporation, based on the production D17S “Staggerwing.” Jackie Cochran set aviation records with both of the D17Ws. The first, c/n 136, was originally sold to famous aviator Frank Monroe Hawks, but that purchase was not completed. Cochran was given the use of the airplane by the Beechcraft.

The Beechcraft Model 17 was single-engine, single-bay biplane operated by a single pilot, and which could carry up to three passengers in an enclosed cabin. The airplane got its nickname, “Staggerwing,” from the lower wing being placed forward of the upper wing for improved pilot visibility. The airplane’s basic structure was a welded tubular steel framework 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 D17-series differed from earlier Beech Model 17 variants by having the fuselage lengthened to improve elevator effectiveness, and the ailerons were on the upper wing.

The D17S was  26 feet, 10.7 inches (8.197 meters) long with a wingspan of 32 feet, 0 inches (9.754 meters) and overall height of 10 feet, 3 inches (3.124 meters). It had an empty weight of 2,540 pounds (1,152 kilograms) and gross weight of 4,250 pounds (1,928 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 17 upper wing was 2 feet, 1–19/32 inches (0.65008 meters) aft of the lower wing. The leading edges had 0° 0′ sweep. Both wings had an angle of incidence of 5° 5′. The upper wing had no dihedral, but the lower wing had +1°. The mean vertical gap between the wings was 5 feet (1.52 meters), and the chord of both wings was 5 feet, 0 inches (1.524 meters). The total wing area was 269.5 square feet (25.04 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 Beechcraft D17S was powered by an air-cooled, supercharged 986.749-cubic-inch-displacement (16.170 liter) Pratt & Whitney R-985-AN-1, ³ a single-row 9-cylinder direct-drive radial engine with a compression ratio of 6:1. This engine was rated at 400 horsepower at 2,200 r.p.m., at 5,000 feet (1,524 meters), maximum continuous power, and 450 horsepower at 2,300 r.p.m. for take off, using 91-octane gasoline. The R-985-AN-1 was 3 feet, 7.05 inches (1.093 meters) long, 3 feet, 10.25 inches (1.175 meters) in diameter and weighed 682 pounds (309 kilograms) when constructed of aluminum, or 674 pounds (306 kilograms), built of magnesium. The engine drove a Hamilton Standard propeller with a diameter 8 feet, 3 inches (2.515 meters).

The production D17S Staggerwing had a cruise speed of 202 miles per hour (325 kilometers per hour) and maximum speed of 212 miles per hour (341 kilometers per hour). The service ceiling was 23,000 feet (7,010 meters) and range was 840 miles (1,352 kilometers).

Beechcraft D17W NX17081 was built for Frank Hawks with an air-cooled, supercharged, 986.749 cubic-inch-displacement (16.170 liter) Pratt & Whitney Wasp Jr. SC-G single-row nine-cylinder radial engine with a compression ratio of 6.7:1. (Engine serial number 531.) This was the only geared variant of the Wasp Jr., and had a reduction ratio of 3:2. This engine was rated at 525 horsepower at 2,700 horsepower up to an altitude of 9,500 feet (2,896 meters) with 87-octane gasoline, and 600 horsepower at 2,850 r.p.m. for takeoff (when using 100-octane aviation gasoline). The additional 150 horsepower greatly increased the D17W’s performance over the standard production airplane. The Wasp Jr. SC-G was 3 feet, 10.469 inches (1.180 meters) long, 3 feet, 10.75 inches (1.187 meters) in diameter and weighed 864 pounds (392 kilograms).

After Jackie Cochran’s speed record, c/n 136 was registered NC17081, re-engined with a 971.930 cubic inch (15.927 liters), 420 horsepower Wright Whirlwind R-975 and re-designated D17R. After changing ownership several times, the Wright engine was replaced with a Pratt & Whitney R-985 and once again re-designated, this time as a D17S.

Early in World War II, the former speed record holder was impressed into military service. It was registered to the Defense Supplies Corporation, Washington, D.C., 14 April 1942, but the registration was cancelled four months later, 11 August 1942. Assigned to the United States Navy, c/n 136 was once again re-designated, this time as a GB-1 Traveler, and assigned Bureau of Aeronautics serial number (“Bu. No.”) 09776.

Beechcraft GB-1 Traveler Bu. No. 09776 was stricken off at NAS Glenview, Illinois, 30 June 1945.

16 July 1957: At 6:04 a.m., Major John Herschel Glenn, Jr., United States Marine Corps, took off from NAS Los Alamitos, on the coast of southern California, in a single-engine Vought F8U-1P Crusader, Bureau Number 144608. 3 hours, 23 minutes, 8.4 seconds later, he landed at Floyd Bennett Field, Brooklyn, New York. Over the 2,360 mile (3,798 kilometer) route, he averaged 725.25 miles per hour (1,167.18 kilometers per hour). This was the first supersonic transcontinental flight.

The purpose of “Project Bullet” was “. . . to test the sustained capability of the F8U at near maximum power over a long distance.” The Crusader’s average speed was faster than the muzzle velocity of a .45-caliber bullet, hence the project name.

Glenn’s aircraft was a photo-reconnaissance variant of the Navy’s F8U-1E carrier-based supersonic fighter. Rather than guns and missiles, it was equipped with six cameras that took panoramic images over the entire route. Though it carried more fuel than the fighter version, the Crusader still required three aerial refuelings to cover the distance. To rendezvous with the North American AJ-1 Savage air tankers, he had to slow and descend by deploying an air brake. After tanking, Glenn accelerated with afterburner and climbed back to 30,000 feet (9,144 meters). As fuel burned off, he gradually rose to 50,000 feet (15,240 meters).

After the completion of the flight, Pratt & Whitney, the engine manufacturer, tore down the J57-P-4A turbojet for an engineering inspection. As a result, all previous power limitations were lifted.

Bu. No. 144608 continued in active service with the Navy and was flown in combat with VFP-63 during the Vietnam War. On 13 December 1972, while landing aboard USS Oriskany (CVA-34), the Crusader struck the ramp of the flight deck and damaged its landing gear. It slid across the deck, severed the arresting cables and went over the side. The pilot, Lieutenant T. B. Scott, ejected safely but the record-setting fighter was lost in the South China Sea.

John Glenn was the Navy/Marine Corps project officer for the Crusader. According to information recently discovered by The Museum of Flight, Glenn made his first flight in a Crusader when he flew the prototype XF8U-1, Bu. No. 138899, on 4 May 1956. According to Glenn’s logbook, he made two flights in the prototype on that date, totaling 2 hours of flight time. (Many thanks to Mike Martinez, a docent for the Museum, for providing this information.)

Soon after Project Bullet, John H. Glenn was selected for Project Mercury. On the third manned flight of the program, he became the first American astronaut to orbit the Earth. He was later elected a United States Senator from his home state of Ohio. At the age of 77, John Glenn flew aboard the Space Shuttle Discovery, STS-95, 29 October–7 November 1998, becoming the oldest person to fly in space.

The Chance Vought F8U-1P Crusader is a photographic reconnaissance variant of the F8U-1 air-superiority fighter. It is a single-place, single-engine turbojet-powered airplane designed to operate from the United States Navy’s aircraft carriers. The recon variant is 54 feet, 6.10 inches (16.614 meters) long with a wingspan of 35 feet, 8 inches (10.871 meters) and overall height (three-point position) of 15 feet, 9.1 inches (4.803 meters). With the wings folded for storage, the span is 22 feet, 6 inches (6.858 meters).

The swept wing is placed high on the fuselage and its angle of incidence is adjustable in flight. The wing has a total area of 375 square feet (34.84 square meters) and has a “dog tooth” leading edge, extending 1 foot, 0.7 inches (0.323 meters). The leading edges are swept aft to 47° (42° at ¼-chord), and there is 5° anhedral. The horizontal stabilator is placed lower than the wings. Its leading edge is swept aft to 50° and it has 3° 25′ dihedral.

The F8U-1P has an empty weight of 16,796 pounds (7,618.5 kilograms), and maximum takeoff weight of 27,822 pounds (12,620 kilograms).

The F8U-1P is powered by a single Pratt & Whitney J57-P-4 engine. The J57 was a two-spool, axial-flow turbojet engine with a 16-stage compressor section (9 low- and 7-high-pressure stages) and a 3-stage turbine section (1 high- and 2 low-pressure stages). Its Normal (continuous) rating is 8,700 pounds of thrust (38.70 kilonewtons) at 5,780 r.p.m. The Military Power rating is 10,200 pounds (45.37 kilonewtons) at 6,100 r.p.m., and it can produce 16,000 pounds (71.17 kilonewtons) at 6,100 r.p.m. with afterburner. The J57-P-4 is 20 feet, 10 inches (6.35 meters) long, 3 feet, 5 inches (1.041 meters) in diameter, and weighs 4,860 pounds (2,205 kilograms).

The F8U-1P has a maximum speed of 635 knots (741 miles per hour/1,176 kilometers/hour) at Sea Level, and 855 knots (984 miles per hour/1,583 kilometers per hour) at 35,000 feet (10,668 meters). Its service ceiling is 41,600 feet (12,680 meters), and it has a combat ceiling of 51,800 feet (15,789 meters) with afterburner. The airplane’s combat range is 1,740 nautical miles (2,002 statute miles/3,222 kilometers) at 495 knots (570 miles per hour/917 kilometers per hour)and 42,350 feet (12,908 meters).

The F8U-1P carried no armament.

Chance Vought built 1,213 F8U Crusaders. 144 were the F8U-1P photo reconnaissance variant. They were retired from U.S. Navy service in 1982.

Colonel Georgy Konstantinovich Mosolov

7 July 1962: Colonel Georgy Konstantinovich Mosolov, Hero of the Soviet Union, flew the Mikoyan-Gurevich E-152\1 to a two-way average speed of 2,681 kilometers per hour (1,666 miles per hour), setting a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 15/25 Kilometer Straight Course.¹

The Mikoyan-Gurevich Ye-152-1 shown with air-to-air missiles and a centerline fuel tank.

The E-152\1 (also known as Ye-152-1) was a prototype interceptor, similar to the production MiG-21. In documents submitted to FAI, the E-152\1 was identified as E-166. Colonel Mosolov made the first flight of the E-152\1 on 21 April 1961. The aircraft displayed at The Central Museum of the Air Forces at Monino, Russia, as E-166 is actually the E-152\2, sister ship of Colonel Mosolov’s record-setting prototype.

This airplane set two other FAI world records. Test Pilot Alexander Vasilievich Fedotov flew it to 2,401 kilometers per hour (1,492 miles per hour) over a 100 kilometer course, 10 October 1961² ; and on 11 September 1962, Pyotr Maksimovich Ostapenko set a world record for altitude in horizontal flight of 22,670 meters (74,377 feet feet).³

The Mikoyan Gurevich E-152\1 is a single-place, single-engine delta-winged prototype all-weather interceptor. It is 19.656 meters (64.448 feet) long  with a wingspan of 8.793 meters (28.848 feet). The leading edge of the wings are swept back to 53° 47′. The empty weight is 10,900 kilograms (24,030 pounds) and takeoff weight is 14,350 kilograms (31,636 pounds).

It was powered by a Tumansky R-15B-300 turbojet engine producing 22,500 pounds of thrust (100.085 kilonewtons) with afterburner. This was the original engine for the MiG-25.

Maximum speed Mach 2.82 (3,030 kilometers per hour, 1,883 miles per hour) at 15,400 meters (50,525 feet). The service ceiling is 22,680 meters (74,405 feet). Internal fuel capacity is 4,960 liters (1,310 gallons), and the E-152\1 could carry a 1,500 liter (396 gallon) external fuel tank. Its range is 1,470 kilometers (913 miles).

After a two-year test program, E-152\1 and its sistership, E-152\2 were converted to E-152M\1 and E-152M\2.

Colonel Georgy Konstantinovich Mosolov, Hero of the Soviet Union

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 assigned as an instructor at the Chuguev Military Aviation School at 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, and Honored Test Pilot of the Soviet Union, 20 September 1967. The Fédération Aéronautique Internationale awarded him its Henry De La Vaulx Medal three times: 1960, 1961 and 1962. The medal is presented to the holder of a recognized absolute world aviation record, set the previous year.

On 11 September 1962, an experimental Mikoyan Ye-8 that Colonel Mosolov was flying suffered a catastrophic compressor failure at Mach 2.15. Engine fragments heavily damaged to prototype and it began to break apart. Severely injured, Mosolov ejected from the doomed airplane at Mach 1.78. He had suffered a severe head injury, two broken arms and a broken leg during the ejection and became entangled in the parachute’s shroud lines. His other leg was broken when he landed in a forest. The following day he suffered cardiac arrest. During a surgical procedure, he went in to cardiac arrest a second time.

Mosolov 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.

Georgy Mosolov served as an international representative for Aeroflot until 1992. He was also a department head at the Higher Komsomol School (Moscow University for the Humanities).

Mosolov was Chairman of the USSR Hockey Federation from 1969 to 1973. He was an Honored Master of Sports of the USSR.

Colonel Georgy Konstantinovich Mosolov, Soviet Air Forces, Hero of the Soviet Union, died 17 March 2018, at Moscow, Russia, at the age of 91 years. He was buried at the Vagankovsoye cemetery in Moscow.

26 May 1961: The Firefly, the Blériot Trophy-winning Convair B-58A-10-CF Hustler, serial number 59-2451, assigned to the 43rd Bombardment Wing, Carswell Air Force Base, Fort Worth, Texas, set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Recognized Course by flying from Washington, D.C. to Paris in 3 hours, 39 minutes, 49 seconds, for an average speed of 1,687.69 kilometers per hour (1,048.68 miles per hour).¹

During the same flight, the B-58 flew the New York to Paris segment in 3 hours, 14 minutes, 44.53 seconds, at an average speed of 1,753.16 kilometers per hour (1,089.36 miles per hour).

The aircrew, Major William R. Payne, Aircraft Commander, Captain William L. Polhemus, Navigator, and Captain Raymond R. Wagener, Defensive Systems Officer, won the Harmon and Mackay Trophies for this flight.

The B-58A Hustler was a high-altitude Mach 2 strategic bomber which served with the United States Air Force from 1960 to 1970. It was crewed by a pilot, navigator/bombardier and a defensive systems operator, each located in individual cockpits. The aircraft had a delta-winged configuration similar to the Convair F-102A Delta Dagger and F-106 Delta Dart supersonic interceptors. The fuselage incorporates the “Area Rule” which resulted in a “wasp waist” or “Coke bottle” shape for a significant reduction in aerodynamic drag. The airplane’s only control surfaces are two “elevons” and a rudder. There are no flaps.

The “Hustler” was 96.8 feet (29.5 meters) long, with a wing span of 56.8 feet (17.3 meters) and an overall height of 31.4 feet (9.6 meters). The wings’ leading edges were swept back at a 60° angle. The wings had a 3°0′ angle of incidence, 2°14′ dihedral, and a total area of 1,542.5 square feet (143.3 square meters).

The B-58A had an empty weight of 51,061 pounds (23,161 kilograms). Its Maximum Takeoff Weight (MTOW) was 90,000 pounds (40,823 kilograms), but once airborne, it could take on additional fuel from a tanker, raising the bomber’s maximum weight to 125,147 pounds (56,766 kilograms).

The B-58A was powered by four General Electric J79-GE-5 afterburning turbojet engines, suspended under the wings from pylons. These were single-shaft axial-flow engines with a 17-stage compressor and 3-stage turbine. The J79-GE-5 had a continuous power rating of 9,700 pounds of thrust (43.15 kilonewtons), Military Power, 10,000 pounds of thrust (44.49 kilonewtons), and Maximum Power, 15,600 pounds (69.39 kilonewtons) with afterburner. (All ratings at 7,460 r.p.m.) The engine was 16 feet, 10.2 inches (5.131 meters) long and 3 feet, 2.0 inches (0.889 meters) in diameter. It weighed 3,570 pounds (1,619 kilograms).

The bomber had a cruise speed of 626 miles per hour (1,007 kilometers per hour) from 30,000 to 50,000 feet (9,144–15,240 meters), and a maximum speed of 1,319 miles per hour (2,124 kilometers per hour) at 56,100 feet (17,099 meters). The B-58’s service ceiling was 67,200 feet (20,483 meters).

Jet fuel (JP-4) was carried in three tanks inside the airplane’s fuselage, and two tanks in a streamlined drop tank. The total capacity of the five tanks was 15,369 gallons (58,178 liters). Its combat radius was 2,589 miles (4,167 kilometers) and the maximum ferry range was 6,483 miles (10,434 kilometers).

The B-58 weapons load was a combination of W-39, B43 or B61 nuclear bombs. The W-39 was carried in the centerline pod. (A two-component mission pod was also available.) The W-39 was the same warhead used on the PGM-11 Redstone intermediate range ballistic missile and the SM-62 Snark intercontinental cruise missile. It was a two-stage radiation-implosion thermonuclear warhead with an explosive yield of 3.8 megatons. The warhead weighed 6,230 pounds (2,826 kilograms). The B-43 and B-61 bombs were carried on four hardpoints under the fuselage.

There was a defensive General Electric M61 Vulcan 20 mm rotary cannon mounted in the bomber’s tail, with a maximum 1,040 rounds of ammunition. The gun was remotely-controlled by the Defensive Systems Officer.

18 March 1937, 5:40 a.m.: Amelia Earhart and her crew sighted Diamond Head on the island of Oahu, Hawaiian Islands. The Electra landed at Wheeler Army Airfield, Honolulu, after an overnight flight from Oakland, California, completing the first leg of a planned around-the-world flight in 15 hours, 47 minutes.

The airplane was Earhart’s Lockheed Electra 10E Special, registration NR16020. Also aboard were Paul Mantz, Amelia’s friend and adviser, as co-pilot, navigator Captain Frederick Joseph Noonan, formerly of Pan American Airways, and Captain Harry Manning of United States Lines, also a close friend of Amelia’s, acting as radio operator and navigator.

About an hour after takeoff from Oakland, California, the Electra overtook the Pan American Airways Hawaii Clipper, which had departed San Francisco Bay an hour-and-a-half before Earhart. She took photographs of the Martin M-130 flying boat.

In her log, Amelia Earhart described the sunset over the Pacific Ocean:

“. . . golden edged clouds ahead, then the golden nothingness of sunset beyond. . .  The aft cabin is lighted with a weird green blue light, Our instruments show pink. The sky rose yellow. . . Night has come. The sea is lovely. Venus is setting ahead to the right. The moon is a life-saver. It gives us a horizon to fly by. . . .”

Amelia: The Centennial Biography of an Aviation Pioneer, by Donald M. Goldstein and Katherine V. Dillon, Brassey’s, Washington and London, 1997, Chapter 18 at Page 171.

On arrival at Hawaii, Earhart, saying that she was very tired, asked Paul Mantz to make the landing at Wheeler Field.
