25 November 1940: Glenn L. Martin Company’s engineer and test pilot William Kenneth Ebel, co-pilot Ed Fenimore and flight engineer Al Malewski made the first flight of the first B-26 Marauder, Army Air Corps serial number 40-1361.

The B-26 was a twin-engine medium bomber designed with high speed as a primary objective. Production of the new airplane was considered so urgent that there were no prototypes. All aircraft were production models.

The B-26 Marauder was 58 feet, 2.5 inches (17.742 meters) long with a wingspan of 65 feet, 0 inches (19.812 meters) ¹ and overall height of 19 feet, 10.3 inches (6.053 meters). At the root, the wings’ chord was 12 feet, 10.5 inches (3.924 meters), with an angle of incidence of 3° 30′. The wing center section had no dihedral, while the the outer panels had +1° 17′. The total wing area was 602 square feet (56 square meters). The bomber had an empty weight of 21,375 pounds (9,696 kilograms) and gross weight of 32,025 pounds (14,526 kilograms).

The prototype was powered by two air-cooled, supercharged, 2,804.4-cubic-inch-displacement (45.956 liter), Pratt & Whitney R-2800-5 two-row, 18-cylinder radial engines with a compression ratio of 6.65:1. The R-2800-5 had a Normal Power rating of 1,500 horsepower at 2,400 r.p.m. to 7,500 feet (2,286 meters) and a Takeoff/Military Power rating of 1,850 horsepower at 2,600 r.p.m. to 2,700 feet (823 meters). They turned 13 foot, 6 inch (4.115 meter) diameter four-bladed, constant-speed Curtiss Electric propellers through a 2:1 gear reduction. The R-2800-5 was 6 feet, 3.72 inches (1.923 meters) long, 4 feet, 4.06 inches (1.322 meters) in diameter, and weighed 2,270 pounds (1,030 kilograms).

40-1361 had a maximum speed of 326 miles per hour (525 kilometers per hour) at 14,250 feet (4,343 meters) with the engines turning 2,400 r.p.m. Its service ceiling was 25,000 feet (7,620 meters), and the absolute ceiling was 26,200 feet (7,986 meters).

When the B-26 entered service, it quickly gained a reputation as a dangerous airplane and was called the “widowmaker,” and also had several less polite nicknames. The airplane had relatively short wings with a small area for its size. This required that landing approaches be flown at much higher speeds than was normal practice. With one engine out, airspeed was even more critical. Some changes were made, such as a slight increase of the wingspan and the size of the vertical fin and rudder> At the same time, an emphasis was made on airspeed control during training. During World War II, the Marauder had the lowest rate of combat losses of any American bomber.

201 B-26s were built before production switched to the B-26A. Glenn L. Martin Co. produced 5,288 Marauders between 1941 and 1945, with manufacturing taking place at Middle River, Maryland, and Omaha, Nebraska. The Marauder served in the Pacific, Mediterranean and European combat areas, with both the United States and several Allied nations. When it was removed from service at the end of World War II, the “B-26” designation was reassigned to the Douglas A-26 Invader, a twin-engine light bomber.

The first Martin Marauder, B-26-MA 40-1361, was written off after a belly landing at Patterson Field, Ohio, 8 August 1941.

William Kenneth Ebel was born at Orangeville, Illinois, 2 January 1899. He was the first of two sons of Willam Henry Ebel, a farmer, and Nora Agnes Rubendall Ebel.

Ken Ebel attended Heidelberg College at Tiffin, Ohio. While at Heidelberg, on 1 October 1918, he enlisted as a private in the Student Army Training Corps (S.A.T.C.). With World War I coming to an end in November, Private Ebel was discharged 20 December 1918. Ebel graduated from Heidelberg in 1921 with a bachelor of arts degree.

Ebel returned to military service, enlisting as a private in the 104th Squadron (Observation), Maryland National Guard, based at Baltimore, Maryland.

Ebel continued his college education at the Case School of Applied Science in Cleveland, Ohio. In 1923, he earned a bachelor of science degree in mechanical engineering (B.S.M.E.)

On 11 September 1923, Private Ebel was appointed an aviation cadet, graduating from primary flying school on 3 June 1924. He received a commission as a 2nd lieutenant, Officers Reserve Corps (O.R.C.), United States Army, on 12 June 1925.

Continuing to serve as a reserve officer, in 1926 Ebel went to work as an engineer for the Glenn L. Martin Company, then located in Cleveland, Ohio. As a test pilot and engineer, Ebel flew the Martin M-130 four-engine flying boar

2nd Lieutenant Ebel,still with the 104th Squadron, Maryland National Guard, was promoted to the rank of 1st lieutenant on 21 December 1928. The U.S. Army advanced his rank to 1st lieutenant, Air Corps, 15 February 1929.

On 21 October 1929, William K. Ebel married Miss Florence E. Sherck at Seneca, Ohio. They would have two children, William Kenneth, Jr., and Lydia Lynn Ebel.

While testing a Martin BM-2 dive bomber, on 11 August 1932, W.K. Ebel “leaped to safety in a parachute Friday when a bombing plane he was testing failed to come out of a spin and crashed at Dahlgren, Virginia. The plane was going through its final tests before being delivered to the navy. It was wrecked in the crash.” Ebel became Member No. 495 of The Caterpillar Club.

25 November 1940: De Havilland Aircraft Company’s Chief Test Pilot, Geoffrey Roal de Havilland, Jr., and engineer John Walker, made the first flight of the DH.98 Mosquito prototype, E0234, at Hatfield, Hertfordshire, England. The multi-role combat aircraft was constructed primarily of layers of balsa covered with layers of birch, then a layer of doped cotton fabric. It was powered by two Rolls-Royce Merlin V-12 engines.

The construction materials took advantage of plentiful supplies of wood, and also made workers who were not in the standard metal aircraft industry able to take part.

The prototype was rolled out 19 November 1040, painted overall yellow.

The prototype had a wingspan of 54 feet, 2 inches (16.510 meters), and its gross weight was 19,670 pounds (8,922 kilograms). W4050 was powered by two liquid-cooled, supercharged, 1,648.96-cubic-inch-displacement (27.01 liter) Rolls-Royce Merlin Mk.21 single overhead camshaft (SOHC) 60° V-12 engines, producing 1,460 horsepower at 3,000 r.p.m. at 10,000 feet (3028 meters), with 10 pounds (0.69 Bar) of boost, and driving three-bladed de Havilland Hydromatic propellers through a gear reduction.

The DH.98 had been predicted to be 20 miles per hour (32 kilometers per hour) faster than the Supermarine Spitfire, but was actually much faster. In testing, the prototype reached 392 miles per hour (631 kilometers per hour) at 22,000 feet (6,706 meters). Improvements were continuously made, and with 2-stage superchargers, W4050 reached a maximum 437 miles per hour (703 kilometers per hour). The DH.98 prototype had a service ceiling of 34,000 feet (10,363 meters) and range of 2,180 miles (3,500 kilometers).

The production fighter variant, the Mosquito F. Mk.II, was 41 feet, 2 inches (12.548 meters) long with a wingspan of 54 feet, 2 inches (16.510 meters) and height of 15 feet, 3 inches (4.648 meters) in 3-point position. The wings had 1½° incidence with approxmatey 2½° dihedral. The leading edges were swept aft 2½°. The total wing area was 436.7 square feet (40.6 square meters). The fighter’s empty weight was 13,356 pounds (6,058 kilograms) and the maximum takeoff weight was 18,649 pounds (8,459 kilograms).

The Mk.II had a cruise speed of 265 miles per hour (426 kilometers per hour) at 15,000 feet (4,572 meters) and maximum speed of 380 miles per hour (612 kilometers per hour) at 21,400 feet (6,523 meters).

Mosquito bomber variants could carry four 500 pound bombs, or two 2,000 pound bombs, but were otherwise unarmed. Fighters were equipped with four Hispano Mk.II 20 mm autocannon and four Browning .303-caliber Mk.II machine guns in the nose.

6,411 DH.98 Mosquitoes were built in England, 1,134 in Canada and 212 in Australia. It was produced in bomber, fighter, night fighter, fighter bomber and photo reconnaissance versions.

W4050’s (the prototype’s Royal Air Force identification) fuselage was damaged while taxiing at Boscombe Down, 24 February 1941, and had to be replaced with one intended for a second prototype, W4051. It remained at de Havilland and was used to test different engines, armaments and versions. After a series of tests conducted in December 1943, the prototype Mosquito was permanently grounded. It was used as an instructional airframe and later placed in storage.

In September 1958, W4050 was turned over to the de Havilland Aircraft Heritage Centre. Today, the restored prototype DH.98 Mosquito is at the museum at London Colney, Hertfordshire, England.

25 November 1920: Lieutenant Corliss Champion Mosely, Air Service, United States Army, won the first Pulitzer Trophy Race flying an Engineering Division-designed-and-built Verville-Packard R-1, serial number A.S. 40126. The race, the first of a series, started at Mitchel Field, Long Island, New York. Turning points were at Henry J. Damm Field, near Babylon, and Lufberry Field at Wantagh. The total length of the race was approximately 132 miles (212 kilometers).

Weather was cold and cloudy, with a threat of snow. The New York Times reported that, With the sun for the most part of the time concealed behind snow clouds, it was possible to watch the contest without suffering eye strain. . . .

Still, more than 25,000 spectators watched the race at Mitchell Field, and several thousand more at each of the turns.

The race began at 11:30 a.m. The 34 entrants took off at intervals for spacing. They would race against the timer’s clock. The first to take off was Captain Harold E. Hartney, U.S. Army Air Service, flying a Thomas-Morse biplane.

Again, from the New York Times:

The interest to the spectators seemed to centre in the much heralded Verville-Packard, which has been undergoing secret tests. . . This machine was the last to start. A cheer went up as the dark gray machine with lightning-like speed mounted into the air, its course being marked by a stream of smoke several hundred feet in length. For a few moments it was lost in the haze and then the powerful craft swooped again into view, crossed over the starting line headed for the Henry J. Damm Field.”

Of the 34 airplanes to start, 11 dropped out from mechanical trouble and 1 was disqualified.

Lt. Moseley’s airplane covered the first lap in eleven minutes six and seventy one hundredths seconds.”  The Verville-Packard R-1 won the race with an elapsed time of 44 minutes, 29.57 seconds, for an average speed of 178 miles per hour. Captain Hartney finished second  with an elapsed time of 47:00.03.

The Chicago Daily Tribune wrote: At last the pride of the Army air service, the Verville-Packard chasse biplane, has established its worth by romping ahead of thirty-four starters in the first Pulitzer trophy aeronautical race, held Thanksgiving day at Mitchel field, Mineola. . . Never in the history of official flying in America has a man traveled with such great velocity. . . .”

Albert Victor Verville

The Verville-Packard R-1 was developed from an experimental fighter, the Verville-Clark Pursuit (VCP-1), designed for the U.S. Army by Alfred Victor Verville, and was the first of a series racing airplanes built for the Army. A single-place, single-engine, single-bay biplane, it had a plywood monocoque fuselage with wood wings and control surfaces covered with doped fabric. The ailerons were on the lower wing, only. The R-1 had an upper and lower wingspan of 23 feet, 0 inches (7.010 meters), with a total area of 222.7 square feet (20.7 square meters). Its gross weight was 3,394 pounds (1,539 kilograms).

In the original pursuit configuration, the VCP-1 was powered by a liquid-cooled Wright Hispano-Suiza V-8 engine producing 300 horsepower. The R-1 Racer substituted a Packard Motor Car Company 1A-2025 engine.

The 1A-2025 was a water-cooled, normally-aspirated, 2,025.444-cubic-inch-displacement (33.191 liter), 60° single overhead cam (SOHC) V-12 engine with four valves per cylinder and a compression ratio of 5.08:1. The engine was rated at 540 brake horsepower (b.h.p.) at 1,800 r.p.m. at Sea Level, 379 horsepower at 10,000 feet (3,048 meters) and 299 horsepower at 15,000 feet (4,572 meters). The total dry weight of the Packard 1A-2025 was 1,142 pounds (518 kilograms).

Corliss Champion Moseley

Corliss Champion Moseley was born at Boise, Idaho, 21 July 1894. He was the first of six children of David Henry Moseley, a farmer, and Clara Leigh Moseley. He attended Long Beach Polytechnic High School, in Long Beach, California, and the University of Southern California (USC), Los Angeles, from 1914 to 1917.

Moseley enlisted as a private in the Signal Corps, U.S. Army, 20 August 1917. Following his graduation from the School of Military Aeronautics at Berkeley, California, he was commissioned a 1st lieutenant, 29 May 1918.

Lieutenant Moseley was sent to France, and is credited with having shot down one enemy airplane. He was promoted to captain, 12 May 1919. Following World War I, the Air Service was reorganized and Moseley was appointed a 1st lieutenant, 1 July 1920. On 15 September 1924, Moseley was promoted to the rank of major. He was assigned as the first commanding officer of the 115th Observation Squadron based at Clover Field, Santa Monica, California. This was the first aviation unit of the California National Guard.

Moseley left the military and in 1925, he founded Western Air Express at Los Angeles, which would become Western Airlines.
