18 December 1941: First Lieutenant Boyd David (“Buzz”) Wagner, United States Army Air Corps, commanding officer of the 17th Pursuit Squadron (Interceptor) at Nichols Field, Pasay City, Commonwealth of the Philippines, shot down his fifth Japanese airplane, a Mitsubishi A6M2 Type Zero fighter, with his Curtiss-Wright P-40B Warhawk, near Vigan, Luzon. He became the first U.S. Army “ace” of World War II.

On 12 December 1941, “Buzz” Wagner was flying a lone reconnaissance mission over the airfield at Aparri, which had been captured by the invading Japanese. He was attacked by several Zero fighters but he evaded them, then returned and shot down two of them.  As he strafed the airfield he was attacked by more Zeros and shot down two more, bringing his score for the mission to four enemy airplanes shot down.

On 18 December, Lieutenant Wagner lead a flight of four P-40s to attack the enemy-held airfield at Vigan. He and Lieutenant Russell M. Church strafed and bombed the field while two other P-40s covered from overhead. Wagner destroyed nine Japanese aircraft on the ground, but as he passed over the field a Zero took off. Wagner rolled inverted to locate the Zero, then after spotting him, chopped his throttle and allowed the Zero to pass him. This left Wagner in a good position and he shot down his fifth enemy fighter. Lieutenant Church was shot down by ground fire and killed.

This fifth shoot down made Buzz Wagner the first U.S. Army Air Corps ace of World War II. He was awarded the Distinguished Service Cross, the Distinguished Flying Cross, and the Purple Heart for injuries sustained in an air battle, 22 December 1941. He was evacuated to Australia in January 1942.

2nd Lieutenant Boyd D. Wagner, Air Corps, United States Army.

Boyd David Wagner was born 26 October 1916 at Emeigh, Pennsylvania. He was the first of two children of Boyd Matthew Wagner, a laborer, and Elizabeth Moody Wagner. After graduating from high school, Wagner enrolled in the University of Pittsburgh, where he majored in aeronautical engineering.

After three years of college, Boyd Wagner enlisted as a flying cadet in the U.S. Army Air Corps, at Pittsburgh, Pennsylvania, 26 June 1937. He was commissioned as a Second Lieutenant, Air Corps Reserve, 16 June 1938. Lieutenant Wagner received advanced flight training and pursuit training, and on 1 October 1938 his commission as a reserve officer was changed to Second Lieutenant, Army Air Corps.

Wagner was promoted to First Lieutenant, Army of the United States, on 9 September 1940. Lieutenant Wagner was assigned to the 24th Pursuit Group in the Philippine Islands, 5 December 1940.

Lieutenant Wagner was promoted to the rank of Captain, A.U.S., 30 January 1942. On 11 April 1942, Captain Wagner was again promoted, bypassing the rank of Major, to Lieutenant Colonel, A.U.S. He was assigned to the 8th Fighter Group in New Guinea. On 30 April 1942, while flying a Bell P-39 Airacobra, Wagner shot down another three enemy airplanes. In September 1942, Colonel Wagner was sent back to the United States to train new fighter pilots.

On 29 November 1942, Colonel Wagner disappeared while on a routine flight from Eglin Field, Florida, to Maxwell Field, Alabama, in a Curtiss-Wright P-40K Warhawk, 42-10271. Six weeks later, the wreck of his fighter was found, approximately 4 miles north of Freeport, Florida. Lieutenant Colonel Boyd David Wagner, United States Army Air Corps, had been killed in the crash. His remains are buried at Grandview Cemetery, Johnstown, Pennsylvania.

The Curtiss-Wright Corporation Hawk 81B (P-40B Warhawk) was a single-seat, single-engine pursuit. It was a low-wing monoplane of all-metal construction and used flush riveting to reduce aerodynamic drag. It had an enclosed cockpit and retractable landing gear. Extensive wind tunnel testing at the NACA Langley laboratories refined the airplane’s design, significantly increasing the top speed.

The P-40B Warhawk was 31 feet, 8¾ inches (9.671 meters) long, with a wingspan of 37 feet, 4 inches (11.379 meters) and overall height of 10 feet, 7 inches (3.226 meters). Its empty weight was 5,590 pounds (2,536 kilograms), and 7,326 pounds (3,323 kilograms) gross. The maximum takeoff weight was 7,600 pounds (3,447 kilograms).

The P-40B was powered by a liquid-cooled, supercharged, 1,710.597 cubic-inch-displacement (28.032 liter) Allison Engineering Co. V-1710-C15 (V-1710-33), a single overhead cam (SOHC) 60° V-12 engine, which had a Continuous Power Rating of 930 horsepower at 2,600 r.p.m., from Sea Level to 12,800 feet (3,901 meters), and 1,150 horsepower at 3,000 r.p.m. to 14,300 feet  (4,359 meters) for Take Off and Military Power. The engine drove a three-bladed Curtiss Electric constant-speed propeller through a 2:1 gear reduction. The V-1710-33 was 8 feet, 2.54 inches (2.503 meters) long, 3 feet, 5.88 inches (1.064 meters) high, and 2 feet, 5.29 inches (0.744 meters) wide. It weighed 1,340 pounds (607.8 kilograms).

18 December 1940: Longtime Curtiss-Wright Airplane Division test pilot Henry Lloyd Child took the prototype XSB2C-1 for its first flight.

The XSB2C-1 was a large dive bomber, intended to replace the U.S. Navy’s Douglas SBD Dauntless. It was designed by a team lead by Curstiss-Wright chief engineer Raymond Cottrell Blaylock (1904–1973).

The prototype had longitudinal stability problems caused by its relatively short fuselage, required to fit on aircraft carrier flight decks.

While on approach to land, 8 Feb 1941, the XSB2C-1 suffered an engine failure and made a hard landing in an open field. The rear of the fuselage was damaged.

The prototype was repaired. Its fuselage was lengthened and a larger vertical fin installed to reduce the stability problems. On 21 Dec 1941 the XSB2C-1 was destroyed after wing failure during flight.

The production SB2C-1 Helldiver a large, single engine, low wing airplane, with a two-man crew: the pilot and a radio operator/gunner. It had conventional retractable landing gear. Its wings could be folded for storage aboard aircraft carriers. It was 36 feet, 8 inches (11.176 meters) long, with a wing span of 49 feet, 8-5/8 inches (15.154 meters), and overall height of 13 feet, 1-½ inches (4.005 meters); the height was 16 feet, 10 inches (5.131 meters) with wings folded. The reduced its width to 22 feet, 6-½ inches (6.871 meters).

The XSB2C-1 powered by an air-cooled, supercharged, 2,603.737 cubic inch displacement (42.668 liter) Curtiss-Wright R2600-8 Twin Cyclone (GR2600B698) two-row, 14-cylinder radial engine with a compression ratio of 6.9:1. It was equipped with a Holley Automatic Type Model 1685-H or -HA carburetor. The right-hand drive engine turned a three-bladed Curtiss Electric Propeller with a diameter of 12 feet (3.658 meters) through a reduction gear ratio of  0.5625:1. The engine required 100-octane aviation gasoline and was rated at 1,500 horsepower at 2,400 rpm; 1,700 horsepower at 2,600 r.p.m., military power; and 1,700 horsepower at 2,800 r.p.m. for takeoff. The R2600-8 was 5 feet, 4.91 inches (1.649 meters) long, 4 feet, 6.26 inches (1.378 meters) in diameter, and weighed 1,995 pounds (905 kilograms). 11,410 of this engine variant were built between April 1940 and May 1944.

The SB2C-1 had a total fuel capacity of 290 gallons (1,098 liters) in one fuselage tank and two wing tanks. An additional 130 gallon (492 liters) tank could be installed in the bomb bay.

The Helldiver’s armament consisted of four air-cooled AN-M2 .50 caliber machine guns in the wings with 240 rounds per gun. A single .50 caliber machine gun with 150 rounds of ammunition was installed in the aft compartment on a flexible mount.   After first 200 production airplanes, the wing machine guns were replaced with two 20 mm automatic cannon, while two .30 caliber machine guns replaced the single aft .50 caliber gun.

The SB2C-1 had a maximum speed 250 miles per hour (402 kilometers per hour) at Sea Level, and maximum speed of 273 miles per hour (439 kilometers per hour)at 13,400 feet (4,084 meters). Its service ceiling was 22,800 feet (6,949 meters). It could climb from Sea Level to to climb to 10,000′ (3,048 meters) in 9.7 minutes, and to 20,000 feet (6,096 meters) 32.6 minutes. The dive bomber’s combat radius, with two 1,000 pound (454 kilogram) bombs and two external fuel tanks was 365 nautical miles (676 kilometers). It had a maximum range of max range 1,375 nautical miles (2,547 kilometers).

7,141 SBC2 Helldivers were built in several variations. 300, designated SBF, were built by Fairchild Aircraft Ltd. (Canada), Longueuil, Quebec; and 834 SBWs by the Canadian Car & Foundry at Fort William, Ontario.

The U.S Army ordered 3,100 Helldiver variants as the A-25A Shrike, but found the airplane inferior in the ground attack role to the Republic Aviation P-47 Thunderbolt. The contract was cancelled with just 900 A-25s produced. These were modified back to the Navy variant and transferred to the U.S. Marine Corps.

17 December 1944: Major Richard Ira Bong, United States Army Air Corps, flying a Lockheed P-38 Lighting over San José on the Island of Mindoro, Commonwealth of the Philippines, shot down an enemy Nakajima Ki-43 Hayabusa (Allied reporting name, “Oscar”).

This was Bong’s 40th confirmed aerial victory and made him the leading American fighter ace of World War II. He is officially credited with 40 aircraft destroyed, 8 probably destroyed and 7 damaged.

Five days earlier, 12 December, during a ceremony at an American airfield on the Island of Leyte, Philippine Islands, General Douglas MacArthur, United States Army, had presented Major Bong the Medal of Honor.

An Associated Press reporter quoted the General:

“Of all military attributes, that one which arouses the greatest admiration is courage. It is the basis of all successful military ventures. our forces possess it to a high degree and various awards are provided to show the public’s appreciation. The Congress of the United States has reserved to itself the honor of decorating those amongst all who stand out as the bravest of the brave. It’s this high and noble category, Bong, that you now enter as I pin upon your tunic the Medal of Honor. Wear it as a symbol of the invincible courage you have displayed so often in mortal combat. My dear boy, may a merciful God continue to protect you is the constant prayer of your commander in chief.”

[On 18 December 1944, Douglas MacArthur was promoted to General of the Army, a five-star rank held by only nine other U.S. military officers. General MacArthur was the son of a Medal of Honor recipient, and had himself been twice nominated for the Medal for his actions during the occupation of Vera Cruz (1914) and the Meuse-Argonne Offensive (1918). He was awarded the Medal of Honor for his defense of the Philippines, 1941–42.]

Richard Bong’s citation reads:

MEDAL OF HONOR

The President of the United States of America, in the name of Congress, takes pleasure in presenting the Medal of Honor to Major (Air Corps) Richard Ira Bong, United States Army Air Forces, for conspicuous gallantry and intrepidity in action above and beyond the call of duty while serving with the 49th Fighter Group, V Fighter Command, Fifth Air Force, in action in the Southwest Pacific area from 10 October to 15 November 1944.

Though assigned to duty as gunnery instructor and neither required nor expected to perform combat duty, Major Bong voluntarily and at his own urgent request engaged in repeated combat missions, including unusually hazardous sorties over Balikpapan, Borneo, and in the Leyte area of the Philippines. His aggressiveness and daring resulted in his shooting down eight enemy airplanes during this period.

Major Bong flew a number of different Lockheed P-38s in combat. He is most associated, though, with P-38J-15-LO 42-103993, which he named Marge after his fiancée, Miss Marjorie Ann Vattendahl, a school teacher from Poplar, Wisconsin.

Richard Bong had flown 146 combat missions. General George C. Kenney, commanding the Far East Air Forces, relieved him from combat and ordered that he return to the United States. He was assigned to test new production P-80 Shooting Stars jet fighters being built at Lockheed Aircraft Corporation’s Burbank, California plant.

On 6 August 1945, the fuel pump of the new P-80 Bong was flying failed just after takeoff. The engine failed from fuel starvation and the airplane crashed into a residential area of North Hollywood, California. Major Richard Ira Bong was killed.

Nakajima Ki-43 Type 1 Army Fighter (AvionsLegendaires.net)

The Nakajima Ki-43 Type 1 Hayabusa was a single-place, single-engine fighter manufactured by Nakajima Hikoki K.K. for the Imperial Japanese Army Air Service. The light weight fighter was very maneuverable and was a deadly opponent. It was identified as “Oscar” by Allied forces. The Ki-43 shot down more Allied airplanes during World War II than any other Japanese fighter.

The Ki-43 was 29.2 feet (8.90 meters) long, with a wingspan of 35.6 feet (10.85 meters) and height of 9 feet (2.74 meters). Its empty weight was 4,170 pounds (1,878 kilograms) and gross weight  was 5,500 pounds (2,495 kilograms).

The Ki-43 Type 1 Army Fighter was powered by an air-cooled, supercharged Nakajima Ha-115 Toku two-row, 14-cylinder radial engine which produced 925 horsepower at 9,350 feet (2,850 meters), 800 horsepower  at 20,000 feet (6,096 meters), and 1,105 horsepower at Sea Level for takeoff. The engine drove a three-bladed constant-speed propeller with a diameter of 9.2 feet (2.80 meters).

Compared to American fighters, the Oscar was lightly armed with just two synchronized 7.7 mm × 58 mm Type 89 or 12.7 mm × 81 mm Type 1 machine guns, or a combination of one 7.7 mm and one 12.7 mm gun. The 12.7 machine gun could fire explosive ammunition. (The Type 89 was a licensed version of the Vickers .303-caliber machine gun, while the design of the Type 1 was based on the Browning M1921 .50-caliber machine gun.)

The Oscar’s maximum speed was 295 miles per hour (475 kilometers per hour) at Sea Level, and 347 miles per hour (558 kilometers per hour) at 20,000 feet (6,096 meters). Its service ceiling was 37,100 feet (11,308 meters). The maximum range with a normal fuel load of 149 U.S. gallons (564 liters) was 1,180 miles (1,899 kilometers) at 1,500 feet (457 meters).

The Lockheed P-38 lightning is a single-place, mid-wing, twin-engine fighter. It is an unusual configuration, with the cockpit, weapons and nose landing gear in a central nacelle, and engines, turbochargers, cooling system and main landing gear in outer “booms.” The airplane was originally designed by Clarence L. “Kelly” Johnson.

The P-38J is 37 feet, 10 inches (11.532 meters) long, with a wingspan of 52 feet, 0 inches (15.850 meters) and overall height of 9 feet, 9-11/16 inches (2.989 meters). The fighter has an empty weight of 12,700 pounds (5,761 kilograms) and maximum gross weight of 21,600 pounds (9,798 kilograms).

The P-38J was powered by two liquid-cooled, turbosupercharged 1,710.597-cubic-inch displacement (28.032 liter) Allison Engineering Company V-1710-F-17R and -F17L (V-1710-89 and -91, respectively) single overhead cam (SOHC) 60° V-12 engines with a continuous power rating of 1,100 horsepower at 2,600 r,p.m., to 30,000 feet (9,144 meters), and a takeoff/military power rating of 1,425 horsepower at 3,000 r.p.m. The counter-rotating engines drove 11 feet, 6 inches (3.505 meters) diameter, three-bladed Curtiss Electric full-feathering constant-speed propellers through a 2.00:1 gear reduction. The engines were 7 feet, 1.34 inches (2.168 meters) long, 3 feet, 0.75 inches (0.933 meters) high, 2 feet, 5.28 inches (0.744 meters) wide, and weighed 1,350 pounds (612 kilograms).

25–29 November 1945

Colonel Joseph Randall Holzapple, commanding officer, 319th Bombardment Group, Light, at Okinawa, 1945.

25–29 November 1945: Colonel Joseph Randall (“Randy”) Holzapple, U.S. Army Air Force, commanding officer of the 319th Bombardment Group, Light, departed Savannah, Georgia, as the pilot of a Douglas A-26C Invader twin-engine light attack bomber. His co-pilot on this flight was Lieutenant Colonel Charles R. Meyers. The navigator was Lieutenant Otto H. Schumaker and Corporal Howard J. Walden was the airplane’s radio operator.

The A-26 headed west, and kept heading west. 90 hours, 54 minutes later, Colonel Holzapple and his crew arrived at Washington National Airport, Washington, D.C. They had flown completely around the world, covering 24,859 miles (40,007 kilometers). The flight time was 96 hours, 50 minutes.

The A-26C Invader was built by Douglas Aircraft Company at its Long Beach, California and Tulsa, Oklahoma plants. It was 51 feet, 3 inches (15.621 meters) long with a wingspan of 70 feet, 0 inches (21.336 meters) and overall height of 18 feet, 6 inches (5.639 meters). It was designed to be flown by a single pilot, with a navigator/bombardier and a gunner. The A-26C weighed 22,690 pounds (10,292 kilograms) empty an had a maximum takeoff weight of 37,740 pounds (17,119 kilograms).

Power was supplied by two air-cooled, supercharged 2,804.4-cubic-inch-displacement (45.956 liter) Pratt & Whitney Double Wasp 2SB-G (R-2800-27) two-row, 18-cylinder radial engines with a compression ratio of 6.65:1. The R-2800-27 had a Normal Power rating of 1,600 horsepower at 2,400 r.p.m. at 5,700 feet (1,737 meters), 1,450 horsepower at 2,400 r.p.m. at 13,000 feet (3,962 meters), and 2,000 horsepower at 2,700 r.p.m for takeoff. War Emergency Power was 2,370 horsepower at 2,700 r.p.m. at Sea level. The engines turned three-bladed propellers with a diameter of 12 feet, 7 inches (3.835 meters) through a 2:1 gear reduction. The R-2800-27 was 6 feet, 3.72 inches (1.923 meters) long, 4 feet, 4.50 inches (1.334 meters) in diameter and weighed 2,300 pounds (1,043 kilograms).

The A-26 was a fast airplane for its time. It had a maximum speed of 323 knots (372 miles per hour/598 kilometers per hour) at 10,000 feet (3,048 meters). The service ceiling was 20,450 feet ( meters) and its range was 1,510 nautical miles (1,738 statute miles/2,797 kilometers) carrying a 4,000 pound (1,814 kilogram) bomb load.

Armament varied. The attack bomber could carry as much as 4,000 pounds (1,814 kilograms) of bombs in the bomb bay and 2,000 pounds (907 kilograms) on underwing hardpoints. Two Browning AN/M2 .50-caliber machine guns were mounted in upper and lower remotely-operated power turrets for defense, and as many as 14 forward-facing fixed .50-caliber machine guns were installed, with eight in the nose and three in each wing.

Randall Holzapple (The 1932 Crest)

Joseph Randall Holzapple was born 7 September 1914 at Peoria, Illinois. He was the fourth of five children of Nathaniel A. Holzapple, a blacksmith, and Annetta Ritchie. He attended Pekin Junior High School, then Peoria High School, where he was a member of the French Club, Science and Math Club, and Drama Club. In his high school yearbook, Holzapple was called “refined” and “handsome.” He graduated in 1932.

In 1938, Randy Holzapple graduated from Bradley Polytechnic Institute, also in Peoria, with a bachelor of science degree in business administration. He then worked as an insurance salesman.

Joseph R. Holzapple enlisted as an aviation cadet in the Air Corps, United States Army, 31 December 1940. At the time, he was 5 feet, 8 inches (1.68 meters) tall and weighed 146 pounds (66 kilograms). He completed his flight training and on 16 August 1941, was commissioned a second lieutenant, Air Reserve.

On 25 March 1942, 2nd Lieutenant Bradley was appointed to the rank of 1st lieutenant, Army of the United States (Air Corps). Six months later, 11 September 1942, he was promoted to captain, A.U.S. (A.C.).

Captain Holzapple was assigned as operations officer of the 319th Bombardment Group (Medium), Eighth Air Force, in England. The group was equipped with the twin-engine Martin B-26 Marauder medium bomber.

14 October 1944

14 October 1944: Ann Gilpin Baumgartner, a member of the Women Airforce Service Pilots (WASPs) assigned as Assistant Operations Officer of the Fighter Section, Flight Test Division, at Wright Field, Dayton, Ohio, made an evaluation flight of the Bell YP-59A Airacomet, becoming the first woman to fly a turbojet-propelled airplane.

The Airacomet was designed and built by the Bell Aircraft Corporation as an interceptor, powered by two turbojet engines. There were three XP-59A prototypes. The first one flew at Muroc Army Airfield on 1 October 1942. The Army Air Corps had ordered thirteen YP-59A service test aircraft. The first of these flew in August 1943 at Muroc.

The Bell YP-59A was conventional single place airplane with retractable tricycle landing gear. It was primarily of metal construction, though the control surfaces were fabric-covered. Its dimensions differed slightly from the XP-59A, having shorter wings with squared of tips, and a shorter, squared, vertical fin. There were various other minor changes, but the exact specifications of the YP-59As are uncertain.

The primary difference, though, was the change from the General Electric I-A turbojet to the I-16 (later designated J31-GE-1). Both were reverse-flown engines using a single-stage centrifugal compressor and a single-stage turbine. The I-16 produced 1,610 pounds of thrust (7.16 kilonewtons). They were 6 feet, 0 inches long, 3 feet, 5.5 inches in diameter and weigh 865 pounds (392 kilograms),

Even with the two I-16s producing 720 pounds of thrust (3.20 kilonewtons) more than the the XP-59A’s I-A engines, the YP-59A’s performance did not improve. Engineers had a lot to learn about turbojeft engine inlet design.

The YP-59A had a maximum speed of 409 miles per hour (658 kilometers per hour) at 35,000 feet (10,668 meters), and its service ceiling was 43,200 feet (13,167 meters).

The P-59 was ordered into production and Bell Aircraft Corporation built thirty P-59A and twenty P-59B fighters. These were armed with one M4 37mm autocannon with 44 rounds of ammunition and three Browning AN-M2 .50-caliber machine guns with 200 rounds per gun.

Although a YP-59A had set an unofficial altitude record of 47,600 feet (14,508 meters), the Airacomet was so outclassed by standard production fighters that no more were ordered.

Ann Gilpin Baumgartner was born 27 Aug 1918, at the U.S. Army Hospital, Fort Gordon, Augusta, Georgia. She was the daughter of Edgar F. Baumgartner, engineer and patent attorney, and Margaret L. Gilpin-Brown Baumgartner. After graduating from Walnut Hill High School, Natick, Massachussetts, she studied pre-med at Smith College, Northampton, Massachussetts. She played soccer and was on the swimming team. She graduated in 1939.

Miss Baumgartner worked as a reporter for The New York Times. She took flying lessons at Somerset Hills Airport, Basking Ridge, New Jersey, and soloed after only eight hours. She then bought  Piper Cub to gain flight experience.

After being interviewed by Jackie Cochran, Baumgartner joined the Women Airforce Service Pilots (WASPs) 23 March 1943, a member of Class 43-W-3, graduating 11 September 1943 with Class 43-W-5. She was then assigned to Camp Davis Army Airfield, Holly Ridge, North Carolina, where she towed targets for anti-aircraft artillery training.

Miss Baumgartner  was transferred to Wright Field, Dayton, Ohio (now, Wright-Patterson Air Force Base), where she flew the B-24 Liberator and B-29 Superfortress heavy bombers, P-38 Lightning, P-47 Thunderbolt, YP-59A Airacomet, P-82 Twin Mustang fighters, and the Luftwaffe Junkers Ju 88 medium bomber.

While at Wright Field, Miss Baumgartner met Major William Price Carl, who was an engineer associated with the P-82. They were married 2 May 1945, and would have two children.

Miss Baumgartner was released from service 20 December 1944, when the WASPs were disbanded. Following World War II, she was employed as an instrument flight instructor for United Air Lines.

After they retired, Mr. and Mrs. Carl sailed the Atlantic Ocean aboard their sailboat, Audacious.

Mrs. Carl was the author of A WASP Among Eagles and The Small World of Long-Distance Sailors.

Ann Gilpin Baumgartner Carl died at Kilmarnock, Virginia, 20 March 2008, at the age of 89 years. She and her husband, who had died one month earlier, were buried at sea.
