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.

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.

Medal of Honor

Citation: On 9 August 1944, Capt. Lindsey led a formation of 30 B-26 medium bombers in a hazardous mission to destroy the strategic enemy held L’lsle Adam railroad bridge over the Seine in occupied France. With most of the bridges over the Seine destroyed, the heavily fortified L’Isle Adam bridge was of inestimable value to the enemy in moving troops, supplies, and equipment to Paris. Capt. Lindsey was fully aware of the fierce resistance that would be encountered. Shortly after reaching enemy territory the formation was buffeted with heavy and accurate antiaircraft fire. By skillful evasive action, Capt. Lindsey was able to elude much of the enemy flak, but just before entering the bombing run his B-26 was peppered with holes. During the bombing run the enemy fire was even more intense, and Capt. Lindsey’s right engine received a direct hit and burst into flames. Despite the fact that his ship was hurled out of formation by the violence of the concussion, Capt. Lindsey brilliantly maneuvered back into the lead position without disrupting the flight. Fully aware that the gasoline tanks might explode at any moment, Capt. Lindsey gallantly elected to continue the perilous bombing run. With fire streaming from his right engine and his right wing half enveloped in flames, he led his formation over the target upon which the bombs were dropped with telling effect. Immediately after the objective was attacked, Capt. Lindsey gave the order for the crew to parachute from the doomed aircraft. With magnificent coolness and superb pilotage, and without regard for his own life, he held the swiftly descending airplane in a steady glide until the members of the crew could jump to safety. With the right wing completely enveloped in flames and an explosion of the gasoline tank imminent, Capt. Lindsey still remained unperturbed. The last man to leave the stricken plane was the bombardier, who offered to lower the wheels so that Capt. Lindsey might escape from the nose. Realizing that this might throw the aircraft into an uncontrollable spin and jeopardize the bombardier’s chances to escape, Capt. Lindsey refused the offer. Immediately after the bombardier had bailed out, and before Capt. Lindsey was able to follow, the right gasoline tank exploded. The aircraft sheathed in fire, went into a steep dive and was seen to explode as it crashed. All who are living today from this plane owe their lives to the fact that Capt. Lindsey remained cool and showed supreme courage in this emergency.

Darrell Robbins Lindsey was born 30 December 1919 at Jefferson, Iowa. He was the second of two sons of Jesse Lyle Lindsey, a civil engineer, and Grace Alice Puffer Lindsey. Darrell Lindsey grew up in Iowa, where he attended Fort Dodge High School, graduating in 1938. He then studied at Buena Vista College at Storm Lake, before transferring to Drake University in Des Moines.

Following his commissioning, Lieutenant Lindsey married Miss Evelyn Scott of Storm Lake, Iowa.

Lieutenant Lindsey next trained as a bombardier at Kirtland Field, New Mexico. He was promoted to first lieutenant and was assigned to a Martin B-26 Marauder operational training unit, the 314th Bombardment Squadron (Medium), at MacDill Army Airfield, near Tampa, Florida. He was promoted to captain in December 1943.

Captain Lindsey was assigned to the 585th Bombardment Squadron (Medium), 394th Bombardment Group (Medium), as a B-26 aircraft commander and flight leader. The unit deployed to Europe in February 1944. The 585th was initially stationed at RAF Boreham (AAF-161) in Essex, but in July 1944, moved to RAF Holmsley South (AAF-455), Hampshire, England.

The bombing mission against the L’Isle-Adam Railroad Bridge on 9 August 1944 was Captain Lindsey’s 46th combat mission. Army Air Corps records indicate that at the time of his death, he had flown a total of 1,497:00 hours. 143 hours were in combat.

Captain Lindsey’s remains were buried at an unknown location. In 1959, a cenotaph memorializing Captain Lindsey was placed at Jefferson Cemetery, Jefferson, Iowa.

The Medal of Honor was presented to Captain Lindsey’s widow, Mrs. Evelyn Scott Lindsey, 9 August 1945, by Major General Robert B. Williams, commanding Second Air Force. In November 1946, Lindsey Air Station at Wiesbaden, Germany, was named in his honor.

In addition to the Medal of Honor, Captain Lindsey was awarded the Distinguished Flying Cross, the Air Medal with eight oak leaf clusters (nine awards), and the Purple Heart.

4 June 1942: The Battle of Midway: The Japanese naval task force (First Mobile Force) under Vice Admiral Chuichi Nagumo, consisting of the aircraft carriers IJN Akagi, IJN Kaga, IJN Hiryu and IJN Soryu, along with their escorts of battleships, cruisers, destroyers and supporting tankers, launched the first attack at 0430 against the United States base at Midway Island. The attackers consisted of 36 Aichi D3A dive bombers, 36 Nakajima B5N torpedo bombers and 36 Mitsubishi A6M Zero fighters as escort.

The incoming aircraft were detected by radar on the island and defending U.S. Marines fighters—obsolescent Grumman F4F Wildcats and obsolete Brewster F2A Buffalos—were launched to defend the island’s airstrip and facilities. 15 U.S. Army Air Force B-17E Flying Fortress heavy bombers and 4 Martin B-26 Marauder medium bombers took off to attack the Japanese carriers.

The Marine fighters were outnumbered and technologically inferior. 4 of the F4Fs and all 12 F2As were shot down. The Japanese lost 4 torpedo bombers and 3 Zero fighters. Facilities on the island were heavily damaged by the dive bomber attack, but it was not put out of action.
