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 boat.

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.

In 1948, Ken Ebel became director of the Airplane Division of the Curtiss-Wright Corporation in Columbus, Ohio. Soon after, Curtiss-Wright sold its airplane division to North American Aviation. In 1950, the U.S. Navy’s primary submarine builder, the Electric Boat Company, appointed Ebel as Vice Pressident of Engineering for its Canadair Ltd., aircraft manufacturing subsidiary in Montreal, Quebec, Canada. (In 1952, after acquiring Convair, the corporation reorganized as General Dynamics.

Ebel returned to the United States in 1961 and served as a consultant for General Dynamics in Washington, D.C. Ebel retired in 1963, purchasing teh Mount Pleasant Orchards near Baltimore.

Mrs. Ebel died in 1968. He later married Helene H. Topping.

William Kenneth Ebel, Ph.D., died at the Greater Baltimore Medical Center, 12 July 1972.

25 November 1940: De Havilland Aircraft Company’s Chief Test Pilot, Geoffrey Raoul de Havilland, Jr., and engineer John Walker, made the first flight of the DH.98 Mosquito prototype, E0234, at Hatfield, Hertfordshire, England. The prototype’s Royal Air Force identification was W4050. 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 total fuel capacity of 553 gallons.

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.

22 November 1972: The Boeing B-52 Stratofortress bombers began combat operations in the Vietnam War with ARC LIGHT strikes against enemy troop concentrations and supply lines in June 1966. The B-52s flew so high and fast that they could neither be seen nor heard on the ground. It was more than six years before the first of the eight-engine bombers would be lost to enemy action.

B-52D-65-BO 55-0110, call sign OLIVE 2, was assigned to the 96th Bombardment Wing, Heavy. It flew combat missions from Andersen Air Force Base, Guam, and the U-Tapao Royal Thai Navy Airfield, Thailand. On 22 November, -110 was crewed by Captain Norbert J. Ostrozny, aircraft commander; Captain P. A. Foley, co-pilot; Bud Rech, radar navigator; Captain Robert Estes, navigator; Larry Stephens, electronic warfare officer; and Staff Sergeant Ronald W. Sellers, gunner.

Near Vinh, on the central coast of North Vietnam, OLIVE 2 was struck by an exploding S-75 Dvina surface to-air missile (NATO identified the S-75 as the SS-2 Guideline, commonly referred to as a SAM). The S-75 is a Soviet two-stage command-guided surface-to-air anti-aircraft missile. It is 10.60 meters (34 feet, 9.3 inches) long and 0.7 meter (2 feet, 3.6 inches) in diameter. It is liquid-fueled and has a maximum speed of Mach 4 and range of 24 kilometers (15 miles). The missile has a 200 kilogram (441 pound) fragmentation warhead. The loaded weight is 2,300 kilograms (5,071 pounds).

OLIVE 2 was seriously damaged and on fire, and the flight crew turned toward the airfield at U-Tapao.

After crossing the Thailand border, Captain Ostrozny ordered the crew to eject from the stricken bomber. All six crewmen escaped the doomed Stratofortress and were later rescued by a Sikorsky HH-53 Super Jolly Green Giant search-and-rescue helicopter.

55-0110 crashed 15 miles (24 kilometers) southwest of Nakhon Phanom, Thailand. It was the first Stratofortress lost to enemy action in more than six years of combat.

22 November 1944: At Lindbergh Field, San Diego, California, a brand new Consolidated Vultee PB4Y-2 Privateer, Bu. No. 59554, took off on its first test flight. A company crew of six men were aboard.

Shortly after takeoff at 12:20 p.m., the left outboard wing of the airplane separated. The airplane immediately went out of control and crashed near a residential area in Loma Portal, a short distance west of the airfield. The wing panel struck the roof of a house at 3121 Kingsley Street. All six crew members were killed. The house was occupied but there were no persons injured inside.

The wing section was recovered and the cause of the separation was quickly discovered. 98 of the 102 bolts which secured it to the inner wing section had never been installed. Two workers who were responsible for installing these missing bolts, and two inspectors who had signed off the work as having been properly completed, were fired.

The Consolidated Vultee PB4Y-2 Privateer was a long range heavy bomber produced for the United States Navy during World War II for patrol, anti-shipping/anti-submarine and bombing missions against Japanese installations on the remote islands of the vast Pacific Ocean area. The Privateer was developed from the Consolidated B-24 Liberator (which was designated PB4Y-1 in U.S. Navy service).

The PB4Y-2 was normally operated by a combat crew of 11–13 men. It was 74 feet, 7 inches (22.733 meters) long with a wingspan of 110 feet (33.528 meters) and overall height of 30 feet, 1½ inches (9.182 meters). The bomber had an empty weight of 39,400 pounds (17,872 kilograms) and its maximum takeoff weight was 64,000 pounds (29,030 kilograms).

The PB4Y-2 was powered by four 1,829.39-cubic-inch-displacement (29.978 liter) air-cooled, supercharged Pratt & Whitney R-1830-94 two-row 14-cylinder radial engines. The turbosuperchargers installed on B-24s were deleted, as high altitude operation was not required by the Navy. The R-1830-94 had a Normal Power rating of 1,100 horsepower at 2,600 r.p.m. to 7,500 feet (2,286 meters), and 1,000 horsepower at 2,600 r.p.m., at 14,700 feet (4,481 meters). The Military Power rating was 1,350 horsepower at 2,800 r.p.m. to 2,000 feet (610 meters), and 1,100 r.p.m. at 2,800 r.p.m. to 13,750 feet (4,191 meters). The engines drove three-bladed Hamilton Standard propellers through a 16:9 gear reduction. The R-1830-94 was 4 feet, 0.40 inches (1.229 meters) in diameter, 4 feet, 11.63 inches (1.515 meters) long and weighed 1,573 pounds (714 kilograms).

The PB4Y-2 Privateer had a cruise speed of 158 miles per hour (254 kilometers per hour) and a maximum speed of 249 miles per hour (401 kilometers per hour) at 12,000 feet (3,658 meters). Its service ceiling was 18,300 feet (5,579 meters) and maximum range of 2,900 miles (4,667 kilometers).

Defensive armament for the Privateer consisted of twelve .50-caliber Browning M2 machine guns mounted in six powered turrets. The maximum bomb load was 8,000 pounds (3,629 kilograms).

The most distinctive visual difference between the B-24/PB4Y-1 Liberator and the PB4Y-2 Privateer is the substitution of a single tall vertical fin for the two outboard oval-shaped fins and rudders of the earlier design. Those two fins blocked the view of gunners as they scanned the skies and oceans. Testing by Ford, the major producer of B-24 Liberators, found that a single large vertical fin also provided better stability. A second identifying characteristic of the Privateer are the gun turrets. A large, spherical, Engineering and Research Corporation (ERCO) ball turret was installed in place of the B-24’s Emerson turret at the nose. Two Martin turrets were placed on top of the fuselage rather than one on the B-24. Two teardrop-shaped ERCO power turrets replaced the open waist gun positions of the Liberator and because they could converge directly under the bomber, eliminated the need for a belly-mounted ball turret.

739 PB4Y-2 Privateers were accepted by the U.S. Navy in 1944–1945. Bu. No. 59544 was deleted from the production contract and payment for that airplane was deducted from the total paid to Consolidated Vultee. The Privateers remained in service with the U.S. Navy until 1954 and with the United States Coast Guard until 1958. Two remain airworthy today, Bu. No. 66300, at the Yanks Air Museum, Chino, California, and Bu. No. 66302, at Goss Hawk Unlimited, Inc., Casa Grande, Arizona. Another six are on display.

The pilot of the Privateer was Marvin Rea Weller. Weller had a ruddy complexion, brown hair and eyes, was 5 feet, 10 inches (1.78 meters) tall, and weighed 143 pounds (65 kilograms). He was born at Augusta, Virginia, 8 August 1919, the fourth of five children of Walton Tobias Weller, a farmer, and Mayna Rea.

Weller graduated from Mt. Sidney High School in Fort Defiance, Virginia, and then attended the Augusta Military Academy, 1937–38.

Marvin Weller was taught to fly by H. P. Grim, Jr., at Staunton Airport, a small airfield five miles northeast of Staunton, Virginia, in 1937. He was then employed as an assistant instructor and flew for a locally-based airline. Later, Weller worked as a flight instructor at Georgia Aero Tech in Augusta, and the Ryan School of Aeronautics at San Diego, California. Both schools provided basic and primary flight instruction for the U.S. Army Air Corps.

Weller married Miss Audrey Lorraine Brubeck of Staunton, 27 April 1941, at Fort Defiance, Virginia. They lived in San Diego.

Marvin Weller had been employed as a test pilot and aircraft commander by Consolidated-Vultee for two-and-a-half years at the time of his death.

The funeral of Marvin Rea Weller was presided by Rev. J.M. McBryde, who married Mr. and Mrs. Weller three years earlier. His remains were interred at the Thornrose Cemetery, Staunton, Virginia.

16 November 2004: Balls 8, the Boeing NB-52B “mothership” at the NASA Dryden Flight Research Center (located at Edwards Air Force Base, California) performs a farewell flyover during its final flight. 52-008 was both the oldest airplane in the U.S. Air Force inventory and the lowest time B-52 Stratofortress still operational.

Boeing RB-52B-10-BO Stratofortress 52-008 was built at Seattle, Washington and made its first flight 11 June 1955. It was turned over to NASA 8 June 1959 for use as a air launch vehicle for the X-15 rocketplane. North American Aviation modified the bomber for its new role at Air Force Plant 42, Palmdale, California. It was redesignated NB-52B.
