21 October 1947: At Northrop Field, Hawthorne, California, Northrop Corporation Chief Test Pilot Max R. Stanley took off in the first YB-49, 42-102367, and flew it to Muroc Air Force Base for flight testing. The co-pilot was Fred C. Bretcher and Orva H. Douglas served as flight test engineer. The Flying Wing landed at Muroc 34 minutes later.

An estimated 4,000 spectators lined the streets surrounding Northrop Field. The YB-49 was escorted by a Lockheed P-80A Shooting Star and a Northrop P-61 Black Widow as it climbed to 10,000 feet (3,048 meters) en route to Muroc. Over Lancaster, California, the P-61 caught fire and was abandoned by its crew.

42-102367 had been converted from the second YB-35 pre-production test aircraft. The original Flying Wing’s four Pratt & Whitney Wasp Major (R-4360-21) radial engines were replaced by turbojet engines and several aerodynamic improvements were made.

The YB-49 was a very unusual configuration for an aircraft of that time. There was no fuselage or tail control surfaces. The crew compartment, engines, fuel, landing gear and armament were contained within the wing. Air intakes for the turbojet engines were placed in the leading edge and the exhaust nozzles were at the trailing edge. Four small vertical fins for improved yaw stability were also at the trailing edge.

The YB-49 had a length of 53 feet, 1 inch (16.180 meters), wingspan of 172 feet (52.426 meters) and overall height of 15 feet, 2 inches (4.623 meters). It weighed 88,442 pounds (40,117 kilograms) empty and its Maximum Takeoff Weight (MTOW) was 193,938 pounds (87,969 kilograms).

The Wing defined the airplane. The leading edge was swept aft 26° 57′ 48″, and the trailing edge, 10° 15′ 22″. The wing’s total area was 4,000 square feet (371.6 square meters). It had an aspect ratio of 7.4:1. At the root, the chord was 37 feet, 6 inches (11.430 meters), tapering to 9 feet, 4 inches (2.844 meters) at the tip. There was 0° angle of incidence at the root, -4° at the wing tips, and 0° 53′ dihedral.

The YB-49 was powered by eight General Electric-designed, Allison Engine Company-built J35-A-5 engines. (This same engine variant was used in the North American Aviation XP-86, replacing its original Chevrolet-built J35-C-3.) The engines were later upgraded to J35-A-15s. The J35 was a single-spool, axial-flow turbojet engine with an 11-stage compressor and single-stage turbine. The J35-A-15 had a Normal Power rating of 3,270 pounds of thrust (14.546 kilonewtons) at 7,400 r.p.m. The Military Power rating was 3,750 pounds (16.681 kilonewtons) at 7,700 r.p.m. The engine was 14 feet, 0.0 inches (4.267 meters) long, 3 feet, 4.0 inches (1.016 meters) in diameter and weighed 2,400 pounds (1,089 kilograms).

The YB-49 had four vertical fins extending above and below the trailing edge of the Wing. (U.S. Air Force 090706-F-1234K-048)

During testing the YB-49 reached a maximum speed of 428 knots (493 miles per hour/793 kilometers per hour) at 20,800 feet (6,340 meters). Cruise speed was 365 knots (429 miles per hour/690 kilometers per hour). The airplane had a service ceiling of 49,700 feet (15,149 meters). The YB-49 had a maximum fuel capacity of 14,542 gallons (55,047 liters) of JP-1 jet fuel. Its combat radius was 1,403 nautical miles (1,615 statute miles/2,598 kilometers).

The maximum bomb load of the YB-49 was 16,000 pounds (7,257 kilograms), though the actual number of bombs was limited by the volume of the bomb bay and the capacity of each bomb type. While the YB-35 Flying Wing was planned for multiple machine gun turrets, the YB-49 carried no defensive armament.

The second ship, YB-49 42-102368, disintegrated in flight during a test flight north of Muroc Air Force Base, 5 June 1948, killing the entire crew, which included Captain Glen Edwards. The name of Muroc was changed to Edwards Air Force Base in his honor.

YB-49 42-102367 was destroyed by fire following a taxiing accident at Edwards, 15 March 1950. The program was cancelled on the same day.

Wiley Hardeman Post (Underwood and Underwood, Washington)

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. He 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

12 April  1918: Allan and Malcolm Loughead, owners of the Loughead Aircraft Manufacturing Company of Santa Barbara, California, set speed and distance records as they flew their twin-engine, ten-place F-1 flying boat from Santa Barbara to San Diego. The F-1 traveled 211 miles (340 kilometers) in 3 hours, 1 minute.¹

The F-1 took off from the waters off West Beach at Santa Barbara at 9:21 a.m., passed Point Fermin at 10:40 a.m., Oceanside at 11:55 a.m., and arrived at North Island at 12:23 p.m.² The airplane was flown by the two Loughead Brothers and carried two passengers.

GREAT SEAPLANE MAKES RECORD ON FLIGHT

     SAN DIEGO, April 12.—The big seaplane F-1, piloted by Malcolm Loughead and carrying three passengers, arrived here at 12:23 this afternoon.

     The F-1 left Santa Barbara at 9:21 this morning and the estimated distance of 190 miles between that city and San Diego was therefore covered in exactly three hours and two minutes, a speed of approximately 63 1-3 miles an hour. The big seaplane was first sighted over Point Loma and within a few minutes alighted on the surface of San Diego Bay a short distance from the United States army aviation station at North Island. At 12:23 the seaplane reached the North Island landing and was hauled ashore by army men in waiting. According to Pilot Loughead, the trip was made without incident, although during the latter part of the trip headwinds were met with which retarded the speed of the aircraft.

————

     Three hours and two minutes by air flight to San Diego from Santa Barbara—that’s the record established today by Allan and Malcolm Loughead, in their big hydroplane, F-1, carrying as passengers Alfred Holt and Carl Christopherson, employees of the Loughead Aeroplane Manufacturing Company.

     The distance of 190 miles, by airplane, was made without mishap. The start from Santa Barbara gathered quite a group of citizens, among them being a number of stockholders in the Loughead company, and thousands would have been there to witness the notable start had it been known at what hour the flight would start.

     During the morning the Lougheads received a dispatch from government officials at the aviation headquarters on North Island, San Diego, informing them that air and ocean conditions were perfect all the way south, and asking that the flight be made today.

     The Lougheads were even at that moment getting ready for the departure, and arrangements were hastened. The bay was ruffled by a breeze, and the combers sparkled in the warm sunlight, as the hydroplane motors were started, and the big fans began to whirr. There were hasty farewells, and every man waved his hat and every woman present shook a kerchief, while the cheers broke forth from all as the big plane sped down the ways, and went skidding into the sea.

     At the wheels were Allan and Malcolm Loughead, while Christopherson and Holt occupied places in the passengers’ quarters at the head of the big plane. The machine was guided in a half circle, taking a southwesterly course at first, until beyond the pleasure pier, where it rose from the bosom of the sea, and rapidly ascended to an altitude of about 500 feet, when it took a southeasterly course, and heading down the channel toward Oxnard.

     It was a perfect get-away, and no bird ever took to the air more gracefully than the big plane rose above the sea and soared away, easily, the very hypothesis of graceful motion, and the speed at which it was travelling soon took it out of sight to the south.

     From Ventura and Hueneme the flight was witnessed by a large number of citizens, and at Point Fermin, near San Pedro, the passing of the plane attracted great interest. In fact, all the way south, great crowds watched eagerly and it was a continuous ovation that greeted the airmen from the land.

     At San Diego the fliers were met by a big crowd, and their stay in the southern city is being made one prolonged reception. From many points along the coast today telephone and telegraph messages have flashed, reporting the passing of the machine, whose eventful trip is the biggest sensation of the day in aviation circles.

     It is stated that the flight establishes a long distance record for a passenger-carrying hydroplane. The plane will be tested out by the government aviation officials, and it is expected that within a very few days the announcement will be made of a contract awarded the Loughead Brothers by the government for other machines.

     Experts who have examined the F-1 state that it is perfectly built, and the finest machine of its class afloat.

Loughead Aircraft Manufacturing Company F-1. (Lockheed Martin).

Designed by friend and employee John Knudson (“Jack”) Northrop, and built in a garage on State Street, the F-1 was launched on a wooden ramp at West Beach.

The airplane was intended for the U.S. Navy, but the end of World War I ended the requirement for new airplanes.

The Loughead F-1 was a twin-engine, three-bay biplane flying boat operated by a crew of 2. It could carry 8–10 passengers. The airplane was 35 feet (10.668 meters) long. The span of the upper wing was 74 feet (22.555 meters) and the lower wing was 47 feet (14.326 meters). The height was 12 feet (3.658 meters). The F-1 had an empty weight of 4,200 pounds (1,905 kilograms) and gross weight of 7,300 pounds (3,311 kilograms).

The F-1 was powered by two right-hand tractor, water-cooled, normally-aspirated 909.22-cubic-inch-displacement (14.899 liters) Hall-Scott A-5-engines. These were inline six-cylinder single-overhead-camshaft (SOHC) engines with a compression ratio of 4.6:1. It was rated at 150 horsepower and produced 165 horsepower at 1,475 r.p.m. The engines were mounted on steel struts between the upper and lower wings. The engines were direct-drive and turned two-bladed, fixed pitch propellers with a diameter of 8 feet, 8 inches (2.642 meters). The Hall-Scott A-5-a was 5 feet, 2.5 inches (1.588 meters) long, 2 feet, 0 inches (0.610 meters) wide and 3 feet, 7.875 inches (1.114 meters) high. It weighed 595 pounds (270 kilograms).

The F-1 had a cruise speed of 70 miles per hour (113 kilometers per hour) and maximum speed of 84 miles per hour (135 kilometers per hour).

The F-1 was converted to a land plane with tricycle undercarriage and redesignated F-1A. During an attempted transcontinental flight, it twice suffered engine failure and was damaged. Reconfigured as a flying boat, the airplane was used for sight-seeing before being sold. It was abandoned on a beach at Santa Catalina Island, off the coast of Southern California, and was eventually destroyed.

The Loughead Aircraft Manufacturing Company would go on to become one of the world’s leading aerospace corporations.

¹ The certifying source for this “record” is not known. The distance flown and elapsed time for the flight cited here are from Wikipedia. The Great Circle distance from today’s Santa Barbara Airport (SBA) to NAS North Island (NZY) is 193 statute miles (311 kilometers). However, contemporary news reports suggest that the Loughead brothers flew the F-1 along California’s southern coastline, rather than making a direct flight across the Santa Barbara Channel, Santa Monica Bay, the Catalina Channel, and on to San Diego Bay. At the time of this flight, the governing body for aviation in the United States was the Aero Club of America, while official flight records were certified by the Fédération Aéronautique Internationale, which was based in France. The ACA ceased to exist in 1923, replaced by today’s National Aeronautic Association. The FAI online records database list only two world records set in 1918, both altitude records set by Major Rudolph Schroeder, 18 September 1918, at Dayton, Ohio.

² The Los Angeles Times, the Oakland Tribune and the San Bernardino Daily Sun state that the time of the takeoff was 9:23 a.m. The Tribune cites the arrival time as 12:24 p.m., while the Daily Sun reported the time as both 12:32 and 12:24. Various newspapers reported the distance flown by the F-1 as 190 miles (306 kilometers), while The Salt Lake Herald-Republican-Telegram printed that it was 200 miles (322 kilometers).

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.”
