15 July 1933: At 5:10 a.m., Wiley Hardeman Post took off from Floyd Bennett Field, Long Island, New York, on a solo around-the-world flight. His airplane was a Lockheed Model 5C Vega, NR105W, which he previously flown around the world in 1931 with navigator Harold Gatty.

On this flight, Post flew approximately the same route around the Northern Hemisphere, making 11 stops ¹ over a 15,596 mile (25,099.3 kilometer) flight. He returned to Floyd Bennett Field at 11:50½ p.m., 22 July 1933, after 7 days, 18 hours, 49½ minutes. Post’s total flight time was 115 hours, 36½ minutes. ²

This was the first solo around-the-world flight. Wiley Post was the first pilot to have flown around the world twice.

“With his touchdown at Floyd Bennett on this evening of July, 22, Wiley Post became the first person to circumnavigate the earth twice by aircraft. Ne was the first person to fly around the world alone, and he had done it with all possible speed. Post’s record remains unique. Fourteen years later in 1947 his record was ostensibly broken; but it was done under such radically different circumstances that the new record was really meaningless.” ³

The Vega was a single-engine, high-wing monoplane designed by John Knudsen Northrop and Gerard Freebairn Vultee. It was a very state-of-the-art aircraft for its time. It used a streamlined monocoque fuselage made of longitudinal strips of vertical grain spruce pressed into concrete molds and bonded together with cassein glue. The wing and tail surfaces were fully cantilevered, requiring no bracing wires or struts to support them. They were built of spruce spars and ribs, covered with 3/32-inch (2.4 millimeters) spruce plywood.

The techniques used to build the Vega were very influential in aircraft design. It also began Lockheed’s tradition of naming its airplanes after stars and other astronomical objects.

The Winnie Mae was built by Lockheed Aircraft Company at Burbank, California in 1930 as a Model 5B Vega, serial number 122. It was purchased by an Oklahoma oil driller, Florence C. (“F.C.”) Hall, on 21 June 1930, and named for his daughter, Winnie Mae Hall, The Winnie Mae of Oklahoma. The new airplane was painted white with purple trim. In 1932, NC105W was modified to the Vega 5C standard.

The Lockheed Model 5C Vega is 27 feet, 6 inches (8.382 meters) long with a wingspan of 41 feet, 0 inches (12.497 meters) and overall height of 8 feet, 2 inches (2.489 meters). Its empty weight is 2,595 pounds (1,177 kilograms) and gross weight is 4,500 pounds (2,041 kilograms).

Winnie Mae was powered by an air-cooled, supercharged 1,343.804-cubic-inch-displacement (22.021 liter) Pratt & Whitney Wasp C, serial number 3088, a single-row, nine cylinder, direct-drive radial engine. The Wasp C was rated at 420 horsepower at 2,000 r.p.m. at Sea Level. It was 3 feet, 6.63 inches (1.083 meters) long with a diameter of 4 feet, 3.44 inches (1.307 meters) and weighed 745 pounds (338 kilograms).

The standard Model 5C had a cruise speed of 165 miles per hour (266 kilometers per hour) and maximum speed of 185 miles per hour (298 kilometers per hour). The service ceiling was 15,000 feet (4,570 meters) and range in standard configuration was 725 miles (1,167 kilometers).

Wiley Post flew the Winnie Mae for F.C. Hall, and flew it around the world in 1931 with Harold Gatty as navigator. Post used it to set several speed records and to compete in the National Air Races. He purchased the airplane from Hall, 8 July 1931.

Winnie Mae was involved in an accident at Chickasha, Oklahoma, 21 April 1933. Flown by another pilot, the engine stopped on takeoff due to fuel starvation. It was found that gasoline had been stolen from the tanks by being siphoned. The damaged Vega was sent to Braniff Airways at Oklahoma City, Oklahoma, for repair and an extensive overhaul. One fuselage half was replaced, and the fuselage covered in balloon cloth. The cockpit was rebuilt, all new control cables installed, and the wing repaired and reinforced. The tail surfaces were recovered and the landing gear was sent to Lockheed to be rebuilt. The Wasp SC1 was completely overhauled modified with new cylinders which increased the compression ratio from 5.25:1 to 6.0:1. The carburetor was overhauled by Bendix-Stromberg, and new magnetos installed. Using 87-octane aviation gasoline, it could produce 500 horsepower at 2,200 r.p.m. (5-minute limit). The airplane’s original two-bladed Standard fixed-pitch steel propeller was replaced by a Smith 450-SI controllable-pitch propeller with Pittsburgh Screw and Bolt hollow steel blades.

Among other modifications, Post had the wing’s angle of incidence decreased 10° which reduced aerodynamic drag and increased the Vega’s speed by 10 miles per hour (16 kilometers per hour). The fixed tail skid was shortened to allow the airplane to reach a higher angle of attack for takeoff and landing. For the 1933 around-the-world flight, six fuel tanks were installed in the fuselage and four in the wings, giving the Vega a total fuel capacity of 645 gallons (2,442 liters). It was also equipped with a Sperry gyroscopic autopilot.

These modifications required the Vega to be licensed in a restricted category, and it was re-registered NR105W.

After Wiley Post was killed in an airplane crash near Barrow, Alaska, 15 August 1935, his widow, Mae Laine Post, sold NR105W to the Smithsonian Institution. It is on display in the Time and Navigation Exhibition at the National Air and Space Museum, Washington, D.C.

² The international organization for flight records, the Fédération Aéronautique Internationale, requires that a circumnavigation cross all meridians in one direction and be at least the length of the Tropic of Cancer, 22,858.729 miles (36,787.559 kilometers). Post’s flight was short of the required distance, so no official record was set.

³ Floyd Odom, Douglas A-26 Invader NX67834, 7–10 August 1947: Flight, “Just what he as proved is not clear. . . The late Wiley Post took come 187 hours to do the circuit. . . but that was fourteen years ago, in a Lockheed Vega with one 450 horsepower engine. Post had far less aid from navigational facilities, and almost only one piece of equipment common to the Winnie Mae and the Reynolds Bombshell is the automatic pilot, which in both cases enabled the human pilot to take occasional short snatches of sleep. Captain Odom’s engines had to run for 73 hours only, while Post’s kept going for 87. Pilot strain must have been approximately proportional to the length of time, so if human endurance is the criterion, Post’s was the greater achievement.”FLIGHT, Vol. 52, August 14, 1947, page 154

11 July 1935: At 5:31 a.m., Eastern Daylight Time, (01:31 UTC) Laura Houghtaling Ingalls took off from Floyd Bennett Field, Brooklyn, New York, and flew non-stop across the North American continent to the Union Air Terminal, Burbank, California. She landed there at 8:51 p.m., Pacific Daylight Time (19:31 UTC). The elapsed time of her non-stop transcontinental flight was 18 hours, 20 minutes, 30 seconds.

After departing Floyd Bennett Field, Ingalls flew along a commercial airway defined by radio beacons. Her route of flight was from Brooklyn, New York, to Pittsburgh, Pennsylvania—Columbus, Ohio—Indianapolis, Indiana—Kansas City, Missouri—Albuquerque, New Mexico—Burbank, California. This was only the third time that a non-stop transcontinental flight had been accomplished.

Her airplane was a single-engine Lockheed Model 9D Orion Special, registration NR14222, which she had named Auto da Fé. ¹ Ingalls had taken delivery of the Orion at the Lockheed Aircraft Company, Burbank, California, 1 February 1935. Contemporary newspaper reports said that the “Black Mystery Ship” cost $45,000.

The Lockheed Model 9 Orion was a single-engine, low-wing monoplane, designed in 1931 by Gerard Freebairn Vultee for airline use. It was capable of carrying six passengers in an enclosed cabin. The Orion was the first commercial airliner with retractable landing gear. It was faster than any military airplane in service at the beginning of the decade. Like other Lockheed aircraft of the time, it was constructed of strong, light-weight, molded wood, but the Orion would be Lockheed’s last wooden airplane.

Auto da Fé was powered by an air-cooled, supercharged, 1,343.804-cubic-inch-displacement (22.021 liter) Pratt & Whitney Wasp S1D1 nine-cylinder radial engine. The engine had a compression ratio of 6:1 and was rated 525 horsepower at 2,200 r.p.m. The S1D1 was a direct-drive engine, which turned a two-bladed Hamilton Standard variable-pitch, constant-speed propeller. The Wasp S1D1 was 4 feet, 3.438 inches (1.307 meters) in diameter, 3 feet, 6.625 inches (1.083 meters) long and weighed 763 pounds (346 kilograms). The engine was enclosed by a N.A.C.A. cowling.

The cruise speed of the Orion was 205 miles per hour (330 kilometers per hour) and the maximum speed was 220 miles per hour (354 kilometers per hour) at Sea Level. It had a range of 750 miles (1,159 kilometers) in standard configuration. The service ceiling was 22,000 feet (6,705 meters).

Ingall’s airplane had a fuel capacity of 630 gallons (2,385 liters) of gasoline and 40 gallons (151 liters) of engine oil. NR14222 was equipped with a Sperry Gyro Pilot and a Westport radio compass and receiver for navigation.

The Greek lower-case letter zeta (the astronomical symbol for the planet Jupiter) was painted on each side of the airplane under the cockpit rails. Ingalls had the same symbol on several of her airplanes. A source suggests that it was used as a stylized representation of her initials, “L.I.” (Her Lockheed Air Express carried the astronomical symbol for the constellation Sagittarius, which was Ingalls’ astrological sign.)

In 1937, NR14222 was sold to Rudolf Wolf, Inc., a burlap company in New York. It was then transferred to Fuerzas Aéreas de la República Española (FARE), the air arm of the Spanish Republican forces during the Spanish Civil War. What happened to the Lockheed Orion after that is not known.

Laura Houghtaling Ingalls was born at Brooklyn, New York, 14 December 1893. She was the first of two children of Francis Abbott Ingalls, a cotton goods merchant, and Laura McAlister Houghtaling Ingalls.

Laura Ingalls, 1920

Miss Ingalls lived in France prior to World War I, and returned there as a relief worker following the War. In 1920, she lived with her family in Tuxedo Park, New York, and was employed as a stenographer.

Laura Ingalls began flight training at Roosevelt Field, Long Island, New York, and completed her first solo flight on 23 December 1928.  In June 1929, she began training for a commercial pilot certificate at the Universal Flying School, Lambert Field, St. Louis Missouri.

Woman Pilot Finishes Studies

     Miss Laura Ingalls, who recently received a limited commercial license, has completed her studies at the Universal Flying School and is taking the examination for a transport license under Inspector Fox. Miss Ingalls’ home is in New York, where she is said to have received several offers of work as a pilot.

St. Louis Post-Dispatch, Vol. 82, No. 212, Sunday, 6 April 1930, Page 6-I, Column 1

Ingalls qualified for her limited transport license, 12 April 1930. (After qualifying for an F.C.C. radio-telephone operator license in 1934, her restricted transport license was upgraded to Scheduled Airline Transport Pilot, 26 January 1935.) Her pilot certificate number was 9330.

Laura Ingalls first gained public attention when she performed 344 consecutive loops with a de Havilland DH.60G Gipsy Moth at St. Louis, NR9720 (c/n 885), 4 May 1930. Three weeks later, she increased the number of loops to 980. On August 13, she completed 714 consecutive barrel rolls in the same airplane. (At the time, the airplane was a demonstrator for the Moth Aircraft Corporation, Lowell, Massachusetts, which was licensed by de Havilland to produce the DH.60 in the United States. Kits were built in England, then assembled in Massachusetts. Miss Ingalls later purchased the airplane, 23 June 1930.)

Laura Houghtaling Ingalls rests against the lower wing of her de Havilland DH.60G Gipsy Moth while its engine idles, October 1930. The forward cockpit is covered.

Miss Ingalls was the first woman to fly across the country from East to West. In 5 October 1930, she flew NR9720 from Roosevelt Field to Grand Central Air Terminal at Glendale, California, arriving 9 October. The flight required nine fuel stops, and took 30 hours and 27 minutes over four days.

Between 28 February and 25 April 1934, Laura Ingalls flew a Lockheed Model 3 Air Express, NR974Y, on a 17,000-mile (27,400 kilometers) solo flight around South America and over the Andes mountain range.

Laura Ingalls was awarded the Harmon Aviatrix Trophy for 1934.

Ingalls flew her Orion in the 1936 Bendix Trophy Race, finishing in second place behind Louise Thaden, with an elapsed time of 15 hours, 39 minutes.

Miss Ingalls bought a Ryan ST-A low-wing monoplane, NC18901 (c/n 179), which was powered by a 125 horsepower Menasco C4 Pirate inverted 4-cylinder engine. The Ryan ST was developed into the Ryan PT-16–22 military trainers of World War II.

In 1939, Laura Ingalls dropped political leaflets during a 2-hour flight over Washington, D.C. On landing, she was met by representatives of the Civil Aeronautics Administration. Her pilot’s license was suspended by the C.A.A. for violating the airspace surrounding The White House. Some sources indicate that the license was later revoked.

After the United States entered World War II, Miss Ingalls was arrested for acting as an unregistered paid agent of Nazi Germany. At trial, she was convicted. She served 1 year, 7 months, 15 days in prison. (Ingalls was initially incarcerated at the federal prison in Washington, D.C., but after having been severely beaten by other prisoners, she was transferred to the womens’ prison in Alderson, West Virginia.)

Laura Houghtaining Ingalls died at her home in Burbank, California, 10 January 1967, at the age of 73 years. Her ashes were interred at Wiltwyck Cemetery, Kingston, New York.

4–5 February 1929: At 5:37:30 p.m., Pacific Time, Monday, Frank Monroe Hawks, took off from Metropolitan Field, Los Angeles, California, (now known as Van Nuys Airport, VNY) in a new Lockheed Model 3 Air Express transport, NR7955, serial number EX-2. Also on board was Oscar Edwin Grubb, the final assembly superintendent for Lockheed. The pair flew non-stop to Roosevelt Field, Long Island, New York, arriving there at 2:59:29 p.m., Eastern Time, on Tuesday. The duration of the flight was 18 hours, 21 minutes, 59 seconds.

Hawks was a technical adviser to The Texas Company (“Texaco”), a manufacturer and distributor of petroleum products which sponsored the flight. On his recommendation, the company purchased the Air Express from Lockheed for use as a company transport.

On 17 January 1930, “Pilot Frank Hawks attempted a takeoff from a soggy field in West Palm Beach, Florida, destroying the aircraft christened ‘Texaco Five’ in a spectacular crash that catapulted it into a row of three parked aircraft. All three occupants were unhurt while the aircraft was destroyed.” —Bureau of Aircraft Accidents Archives

NC7955’s Department of Commerce registration was cancelled 31 January 1930.

The Lockheed Model 3 Air Express was a single-engine parasol-wing monoplane transport, flown by a single pilot in an open aft cockpit, and capable of carrying 4 to 6 passengers in its enclosed cabin. The airplane was designed by Gerard Freebairn Vultee and John Knudsen Northrop. It used the Lockheed Vega’s molded plywood monocoque fuselage.

The Model 3 received Approved Type Certificate No. 102 from the Aeronautic Branch, U. S. Department of Commerce.

The Lockheed Air Express was the first production airplane to use the “NACA Cowl,” an engine cowling for radial engines which had been designed by a team led by Fred Ernest Weick of the the National Advisory Committee for Aeronautics’ Langley Memorial Aeronautical Laboratory. The new cowling design tightly enclosed the engine and used baffles to control air flow around the hottest parts of the engines. The exit slots were designed to allow the air to exit the cowling at a higher speed than it had entered the intake. The new cowling design provided better engine cooling and caused significantly less aerodynamic drag. The addition of the NACA cowling increased the Air Express’s maximum speed from 157 to 177 miles per hour (253 to 285 kilometers per hour).

The day following Hawks’ transcontinental flight, Vultee sent a telegram to NACA:

COOLING CAREFULLY CHECKED AND OK. RECORD IMPOSSIBLE WITHOUT NEW COWLING. ALL CREDIT DUE TO NACA FOR PAINSTAKING AND ACCURATE RESEARCH. GERRY VULTEE, LOCKHEED AIRCRAFT CO.

The Lockheed Model 3 Air Express was 27 feet, 6 inches (8.382 meters) long with a wing span of 42 feet, 6 inches (12.954 meters) and height of 8 feet, 4½ inches (2.553 meters). The wing area was 288 square feet (26.756 square meters). The wing had no dihedral. The airplane had an empty weight of 2,533 pounds (1,149 kilograms) and gross weight of 4,375 pounds (1,984 kilograms).

The Model 3 was powered by an air-cooled, supercharged 1,343.804-cubic-inch-displacement (22.021 liter) Pratt & Whitney Wasp C nine cylinder, direct-drive radial engine. The Wasp C was rated at 420 horsepower at 2,000 r.p.m. at Sea Level. It was 3 feet, 6.63 inches (1.083 meters) long, 4 feet, 3.44 inches (1.307 meters) in diameter, and weighed 745 pounds (338 kilograms).

The Air Express had a cruising speed of 135 miles per hour (217 kilometers per hour), and maximum speed of 177 miles per hour (285 kilometers per hour). It’s service ceiling was 17,250 feet (5,258 meters).

Francis Monroe Hawks was born at Marshalltown, Iowa, 28 March 1897. He was the son of Charles Monroe Hawks, a barber, and Ida Mae Woodruff Hawks. He attended Long Beach Polytechnic High School, Long Beach, California, graduating in 1916. He then studied at the University of Southern California, in Los Angeles.

Frank Hawks was an Air Service, United States Army, pilot who served during World War I. He rose to the rank of Captain, and at the time of his record-breaking transcontinental flight, he held a commission as a reserve officer in the Army Air Corps. Hawks transferred to the U.S. Naval Reserve with the rank of Lieutenant Commander. His date of rank 27 May 1932.

His flying had made him a popular public figure and he starred in a series of Hollywood movies as “The Mysterious Pilot.”

On 28 December 1920, Miss Amelia Earhart took her first ride in an airplane at Long Beach Airport in California. The ten-minute flight began her life-long involvement in aviation. The airplane’s pilot was Frank Monroe Hawks.

Francis M. Hawks married Miss Newell Lane at Lewiston, Montana, 7 August 1918. They had a daughter, Dolly. They later divorced. He next married Mrs. Edith Bowie Fouts at St. John’s Church, Houston, Texas, 26 October 1926.

Frank Hawks was killed in an aircraft accident at East Aurora, New York, 23 August 1938. He was buried at Redding Ridge Cemetery, Redding, Connecticut.

14–15 January 1935

Jimmy Doolittle in the cockpit of American Airlines’ Vultee V-1A NC13770, January 1935. (NASM-157196)

14–15 January 1935: James Harold Doolittle set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Recognised Course of 329.98 kilometers per hour (205.04 miles per hour).¹

Doolittle took off from Union Air Terminal, Burbank, California, at 5:27 p.m., Pacific Standard Time, 14 January (8:27 p.m., Eastern Standard Time). Also on board were Mrs. Doolittle and Robert Adamson (1871–1935), an executive with the Shell Oil Company.

The airplane was a Vultee V-1A Special, NC13770, owned by American Airlines and leased to Shell.

Doolittle crossed overhead Floyd Bennet Field at 8:26 a.m., Eastern Standard Time, 15 January. He then landed at Newark Airport, New Jersey, at 8:34½ a.m. The flight from Burbank to Brooklyn had a duration of 11 hours, 59 minutes, and broke a record set two months earlier by Eddie Rickenbacker.

The Vultee V-1A was a large, all-metal, single-engine airliner of full monocoque construction with retractable landing gear. It could be flown by one or two pilots and carry up to eight passengers. The V-1A was designed by Gerard Freebairn Vultee and Richard Palmer, based on an earlier design by Vultee and Vance Breese, who were working for the Airplane Development Corporation. The prototype made its first flight 19 February 1933 with test pilot Marshall Headle at the controls.

NC13770, serial number 24073, was the eighth V-1A built, and was one of the original ten ordered by American Airlines. The V-1A was 37 feet, 0 inches (11.278 meters) long with a wingspan of 50 feet, 0 inches (15.240 meters) and height of 10 feet, 2 inches (3.099 meters). The wings had root chord of 11 feet, 3 inches (3.429 meters) and tip chord of 5 feet, 0 inches (1.524 meters). Total wing area was 384.0 square feet (35.675 square meters). There was 3° dihedral. The V-1A had an empty weight of 5,212 pounds (2,364 kilograms) and gross weight of 8,500 pounds (3,856 kilograms).

Vultee V-1A Special NR13770

The Vultee V-1A was powered by an air-cooled, supercharged, 1,823.129 cubic-inch displacement (29.785 liter) Wright Aeronautical Division Cyclone 9 R-1820-F2 ² (R-1820-20 or R-1820-102), a nine-cylinder radial engine with a compression ratio of 6.4:1. This was a direct-drive engine with a Normal Power rating of 691 horsepower at 1,950 r.p.m., at Sea Level. It required 87-octane gasoline. The R-1820-F2 was 3 feet, 7-3/8 inches (1.102 meters) long, 4 feet, 5-3/4 inches (1.365 meters) in diameter, and weighed 937 pounds (425 kilograms).

The V-1A had a cruise speed of  215 miles per hour (346 kilometers per hour) and maximum speed of 235 miles per hour (378 kilometers per hour). The airplane’s service ceiling was 23,000 feet (7,010 meters). In standard configuration, it had a range of 1,000 miles (1,609 kilometers).

NC13770 was later sold to Harry Richman of Miami Beach, Florida, who christened the airplane Lady Peace. It registration was cancelled 8 October 1937. During the Spanish revolution, the airplane was captured by the Nationalists. It is believed to have been scrapped in the early 1950s.

¹ FAI Record File Number 13232

² Some sources identify the Vultee V-1A’s engine as the Wright SR-1820-F2 (R-1820-05, R-1820-37, and R-1820-84). These engine variants have the same compression ratio, dimensions and weights as the R-1820-F2. The Normal Power rating for the -05 is 840 horsepower at 1,950 r.p.m.; the -37 is 690 horsepower at 1,950 r.p.m.; and the rating for the -84 is 740 horsepower at 1,950 r.p.m. Two contemporary aviation news magazines identified the engine as simply a “Wright Cyclone F2,” which is less than helpful, as there are at least 8 different “-F2” variants, designated as R-1820-F2, GR-1820-F2, SR-1820-F2 and SGR-1820-F2. Some of these have military versions; others do not. Normal Power ratings for these -F2 engines range from 664 to 840 horsepower, all at 1,950 r.p.m.
