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.

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 1961: In recognition of the 50th Anniversary of Naval Aviation, a number of speed and altitude record attempts were planned, using the U.S. Navy’s new McDonnell YF4H-1 Phantom II fighter. On the morning of 22 November, Lieutenant Colonel Robert Bradford Robinson, Jr., United States Marine Corps, took off from Edwards Air Force Base on Operation Skyburner, an attempt to set a new World Absolute Speed Record. He was flying the second Phantom II built, Bu. No. 142260.

The Phantom carried three external fuel tanks for this flight. It had a 600-gallon (2,271.25 liter) centerline tank and two 370-gallon (1,400.6 liter) wing tanks. Robinson flew southeast toward NAS El Centro, then turned back to the northwest. Over the Salton Sea, he began to accelerate the YF4H-1 to build up speed for the record run over a measured twenty-mile course back at Edwards AFB. The Phantom’s two General Electric J79-GE-3A afterburning turbojets used a tremendous amount of fuel at full throttle and the centerline fuel tank was quickly emptied. Robinson jettisoned the empty tank over the Chocolate Mountain gunnery range. Continuing to accelerate, the two wing tanks were next jettisoned as they ran dry, this time at Bristol Dry Lake.

The Phantom entered the east end of the speed course in full afterburner. Having burned off more than 1,300 gallons of fuel, 142260 was much lighter now, and aerodynamically cleaner after dropping the external tanks. Robinson exited the west end of the 20-mile (32.2 kilometer) course in less than one minute.

Fédération Aéronautique Internationale rules require that a speed record must be made with two passes in opposite directions. The average speed of the two runs is the record speed. The Phantom was flying so fast that it covered another 105 miles (169 kilometers) before it could turn around. During the turn, it was still traveling at 0.9 Mach.

Robinson again put the engines in afterburner as he approached the course from the west. On the second run, the fighter was even lighter and its recorded speed was more than 1,700 miles per hour (2,736 kilometers per hour). The average of the two runs was calculated at 2,585.425 kilometers per hour (1,606.509 miles per hour.) This was the new FAI Absolute World Speed Record.¹

For his accomplishment, Lieutenant Colonel Robinson was awarded the Distinguished Flying Cross by Secretary of the Navy John B. Connally. The presentation took place on 25 November 1961 at Newport News, Virginia, during the commissioning of USS Enterprise CVA(N)-65.

In the next few weeks, the same YF4H-1 would establish a world record for sustained altitude—20,252 meters (66,444 feet).² Two years earlier, 6 December 1959, in Operation Top Flight, 142260 had established a world record for absolute altitude when it zoom-climbed to 98,557 feet (30,040 meters).³

Bob Robinson attended Orange Union High School, graduating in 1941. He participated in all varsity sports, and was selected to attend the Boys’ State leadership program. He earned a bachelor of science degree at Washington University, St. Louis, Missouri.

Robinson entered the United States Marine Corps on 26 August 1942. He received the wings of a Naval Aviator and was commissioned as a second lieutenant on 1 December 1943.

2nd Lieutenant Robinson married Miss Lavonne Jean David at Nueces, Texas, 23 December 1943. They would later have a son, Robert Bradford Robinson III (and a grandson, Robert Bradford Robinson IV)

During the Battle of Okinawa, Lieutenant Robinson flew the radar-equipped Grumman F6F-3N Hellcat night fighter with VMF(N)-543.

Lieutenant Robinson was promoted to the rank of first lieutenant, 31 March 1945. Following World War II, Lieutenant Robinson was assigned to VMF-311, and became one of the first Naval Aviators to qualify in turbojet-powered aircraft. The squadron initially flew the Lockheed TO-1 Shooting Star (P-80), and later transitioned to the Grumman F9F Panther.

Lieutenant Robinson was promoted to the rank of captain 1 April 1950. VMF-311 was sent to the Korean war zone in November 1950, initially operating from Yokosuka Air Base in Japan. The squadron flew close air support missions in support of the amphibious assault of Inchon, and at the Battle of the Chosin Reservoir. Captain Robinson returned to night fighter operations when he joined Marine All-Weather Squadron 513 (VMF(N)-513) on 13 January 1951.

Captain Robinson was promoted to the rank of major, 31 December 1954. He completed the six-month course at the Naval Test Pilot School, NAS Patuxent River, Maryland, graduating in March 1959 (Class 21).

In 1963, Lieutenant Colonel Robinson retired from the Marine Corps after 20 years’ service. He was then employed as a test pilot for the McDonnell Aircraft Corporation at St. Louis, Missouri. He remained with the company for 30 years.

Mrs. Robinson died 7 February 1997, after 53 years of marriage. Bob Robinson later married Mrs. Julian Brady (née Elizabeth Catchings), the widow of a long-time friend.

Robert Bradford Robinson, Jr., died 28 September 2005 at McComb, Mississippi. He was buried at the Hollywood Cemetery in McComb.

21 November 1947: Grumman Aircraft Engineering Corporation engineering test pilot Corwin Henry (“Corky”) Meyer took off from the company’s  airfield at Bethpage, Long Island, New York, in the first prototype XF9F-2 Panther, Bu. No. 122475. After the preliminary flight evaluation, Meyer landed the new jet fighter on a longer runway at Idlewild Airport. The Bethpage runway was only 5,000 feet (1,524 meters) long. As the first jet aircraft built by Grumman, it wasn’t known if the XF9F-2 could land on that short a runway.

Air & Space/Smithsonian magazine quoted Meyer as saying that the weather was “the foulest of any first flight in my experience.” He described the prototype’s handling qualities: “It handled like a J-3 Cub.” In an article for Flight Journal, Corky Meyer wrote: “I conducted a very satisfactory first flight of the 5,000-pound-thrust Rolls-Royce Nene-powered fighter on November 21, 1947.”

The XF9F-2 Panther was the first jet-powered aircraft to be built by Grumman, a major supplier of aircraft for the United States Navy. It was a single-seat, single-engine, day fighter, designed for operation on the U.S. Navy’s aircraft carriers. It was developed from a proposed four-engine XF9F-1 night fighter. Grumman planned to use the Rolls-Royce RB.41 Nene centrifugal-flow turbojet engine. With 5,000 pounds rated thrust at 12,400 r.p.m., the Nene was more powerful (and more reliable) than any engine manufactured by an American company.

The Nene was licensed for production in the United States to the Taylor Turbine Corporation as the J42-TT-2. No J42s were ready, so Taylor supplied Grumman with imported Rolls-Royce engines. The Navy had concerns about Taylor’s capability to produce engine in sufficient quantities and arranged for the J42 license to be sold to Pratt & Whitney.

The Panther was placed into production as the F9F-2. The F9F-2 was 37 feet, 5-3/8 inches (11.414 meters) long with a wingspan of 38 feet, 5⅜ inches (11.719 meters) long, with a wingspan of 38 feet, 0 inches (11.528 meters)—not including wing tanks. Its overall height was 11 feet, 4 inches (3.454 meters). The wings could be hydraulically folded to reduce the span for storage aboard ship. The Panther weighed 9,303 pounds (4,220 kilograms) empty, and had a gross weight of 19,494 pounds (8,842 kilograms.

The F9F-2 was powered by a Pratt & Whitney JT6 (J42-P-8) turbojet engine which produced 5,000 pounds of thrust (22.241 kilonewtons) at Sea Level, and 5,750 pounds (25.577 kilonewtons) with afterburner. The J42 was a license-built version of the Rolls-Royce Nene. The engine used a single-stage centrifugal-flow compressor, 9 combustion chambers and a single-stage axial-flow turbine. The J42-P-8 weighed 1,715 pounds (778 kilograms).

The Panther had a maximum speed of 575 miles per hour (925 kilometers per hour) at Sea Level. Its service ceiling was 44,600 feet (13,594 meters), and the range was 1,353 miles (2,177 kilometers).

The Panther was armed with four M3 20 mm autocannon placed in the nose with 760 rounds of ammunition. It could carry up to 3,000 pounds (1,361 kilograms) of bombs or eight 5-inch (12.7 centimeters) rockets on four hardpoints under each wing.

It was a very successful air-to-air and air-to-ground fighter during the Korean War. On 18 November 1952, Lieutenant Elmer Royce Williams, USN, flying an F9F-5 Panther, Bu. No. 125459, of VF-781 aboard the aircraft carrier USS Oriskany (CVA-34), shot down four of seven Soviet Air Force MiG 15 fighters which had launched from Vladivostok toward Task Force 77. His Panther sustained significant damage from enemy cannon shells. Though he safely returned to his carrier, the fighter, Number 106, was so badly damaged that it was pushed over the side. Lieutenant Williams was awarded the Silver Star for this action. No other pilot has ever shot down four MiG fighters during a single combat action.

The F9F Panther was flown during the Korean War by such famed naval aviators as Ted Williams, and future astronauts John Glenn and Neil Armstrong.

Grumman built 1,358 F9F-2,-3,-4 and -5 Panthers and another 1,392 swept wing F9F-6, -7 and -8 Cougars. Panthers remained in service with the United States Navy until 1958, and Cougars until 1974.

At the age of 17 years, Corky Meyer learned to fly in the Civilian Pilot Training Program. (This was a federal government-funded program which provided 72 hours of ground school and 35–50 hours of flight training, intended to increase the number of pilots available for civilian aviation.)

Meyer attended Springfield High School, in Springfield. He was a member of the Senior Boys’ Council and the National Honor Society. Meyer graduated from high school in May 1938, then entered the University of Illinois. He studied at the at the Massachusetts Institute of Technology (M.I.T.), Cambridge, Massachusetts, 1942–43.

Meyer was a pilot trainee for Pan American Airways before being employed as an engineering test pilot at the Grumman Aircraft Engineering Corporation at Bethpage, New York.

Meyer’s first project was testing newly-built TBF Avenger torpedo bombers. Later he was was a project test pilot for the F6F Hellcat, F8F Bearcat and F7F Tigercat. (Robert Leicester Hall made the first flights of these airplanes, but Corky Meyer was involved in flight testing of each of them early on.)

Corky Meyer made the first flight of the XF9F-9 prototype, Bu. No. 138604, on 30 July 1954, and was able to approach mach 1 in level flight. The XF9F-9 was a completely redesigned F9F Cougar, which incorporated the “wasp-waist” in its area-ruled fuselage. The following year, this type would be redesignated the F11F Tiger.

In 1967, Meyer was appointed  vice president of Grumman, and in 1968, he was elected to the board of directors of the Grumman Aerospace Corporation. He became the senior  vice president of Grumman Aerospace in 1972. In 1974, Meyer became President of Grumman American Aviation Corp., Savannah, Georgia, a subsidiary which produced light civil airplanes, the Grumman AgCat, and the Gulfstream line of executive jets. Corwin Meyer retired from Grumman in 1978. He later served as chief executive officer of the Enstrom Helicopter Corporation and the Falcon Jet Corporation.

Meyer was an early member of the Society of Experimental Test Pilots. In 1971, he was awarded SETP’s James H Doolittle Award for excellence in technical management or engineering achievement in aerospace technology. In 1999 the National Aeronautic Association selected him for its Elder Statesman Award.

Meyer was the author of Corky Meyer’s Flight Journal, an autobiography published in 2005, by Specialty Press, North Branch, Minnesota.

Corwin Henry Meyer died in Naples, Florida, 1 June 2011, at the age of 91 years.

¹ Lutheran Church birth and baptismal records give Meyer’s name as “Henry Corwin Meyer.”

² On 3 April 1991, TDiA’s author became the only civilian helicopter pilot (at that time, and who was not a former military pilot) to qualify to fly from U.S. Navy warships at sea. The Deck Landing Qualification (DLQ) flights were evaluated by instructors from Helicopter Antisubmarine (Light) Squadron (HSL-31) aboard USS Kincaide (DDG-965), a Spruance-class guided missile destroyer.

20 November 1940: North American Aviation’s Chief Test Pilot, Paul Baird Balfour, made his first flight in the NA-73X, NX19998, prototype for a Royal Air Force fighter, the Mustang Mk.I.

Vance Breese was the free-lance test pilot who made the first seven flights in the new airplane. Breese claimed to have made a bet with North American executives that Balfour would crash the prototype on his first flight.

This flight was scheduled to be a high speed test. Edgar Schmued, the designer, offered to show Balfour around the airplane. “Before this flight, I asked Balfour to get into the airplane and go through the routine of a takeoff and flight. He responded that one airplane is like another and he would not need the routine checkout.”

The ground crew started the NA-73X’s 1,150 horsepower Allison V-1710-39 liquid-cooled V-12 engine at 5:40 a.m. and let it warm up to normal operating temperature. When it was restarted just prior to Paul Balfour’s flight, “it was a little hard to start,” according to Olaf Anderson, the airplane’s mechanic.

Balfour took off from Mines Field at about 7:10 a.m. After about twelve minutes of flight, the Allison stopped running. Balfour was too far from Mines Field to make it back to the runway. He landed in a plowed field west of Lincoln Boulevard. When the tires hit the soft surface, the prototype flipped over. Balfour was not hurt and was able to crawl out of the upside-down wreck.

The Civil Aeronautics Board report described the damage as “engine housing broken, both wingtips damaged, tail surfaces damaged, top of fuselage damaged, and other miscellaneous damage.” The NA-73X had accumulated just 3 hours, 20 minutes of flight.

Vance Breese won his bet.

According to the C.A.B. investigation, the engine had stopped due to fuel starvation when Balfour neglected to select another tank.

The prototype was taken back to the factory and rebuilt. It would become the famous Mustang, one of the most significant aircraft of World War II.

Robert C. Chilton was hired as the new Chief Test Pilot. He would continue testing the Mustang developments throughout the war. Chilton made his first flight in NA-73X on 3 April 1941.

Paul Balfour continued to work for North American Aviation, testing the NA-40 and NA-40B prototypes and the B-25 Mitchell medium bomber. He later served in the United States Air Force.

Paul Baird Balfour was born 5 July 1908 in Washington State. He was the son of Fred Patrick Balfour and Edna May Baird Balfour. Balfour attended two years of college.

Paul Balfour entered the U.S. Army Air Corps (prior to 1930). He was stationed at Rockwell Field, San Diego, California.

Balfour married Martha Lillette Cushman of Coronado, California, at Yuma, Arizona, 6 June 1930.

Balfour began working as a test pilot for North American Aviation, Inc., 1 March 1936.

On 2 July 1938, he married Lois Tresa Watchman at Kingman, Arizona. They would have two children.

On 9 November 1951, Major Paul B. Balfour, U.S. Air Force, attached to the 1002nd Inspector General Group at Norton Air Force Base, California, was flying a North American VB-25J, 44-30955, a transport conversion of a B-25J-30-NC Mitchell medium bomber.

Shortly after takeoff, at about 10:00 a.m., the airplane developed engine trouble. Unable to return to Norton, Balfour attempted a belly landing at a small private airfield. Witness saw that the airplane’s left engine was idling, and its propeller was feathered. As he approached, the airplane was blocked by a windbreak of eucalyptus trees bordering U.S. Route 66. Balfour banked away from the trees but the B-25 crashed in an orange grove along Bloomington Avenue in Rialto, approximately 7 miles (11 kilometers) north of Norton.

Balfour, still buckled in his seat, was thrown clear of the burning wreck and landed in the street. One man on board was killed and two others seriously injured. Balfour died in a hospital three hours later. He was 41 years old. Major Balfour was buried at the Inglewood Park Cemetery, Inglewood, California.
