23 September 1917: Leutnant Werner Voss, commanding officer of Jagdstaffel 10 of the Deutsche Luftstreitkräfte (German Air Force), a leading fighter ace with 48 confirmed victories, was shot down during a battle which lasted at least eight minutes and involved seven British pilots, themselves aces.
Though Voss’ machine gun fire damaged most of his opponents’ airplanes, his own was hit by fire from at least two of the British airplanes. Voss was struck by three bullets.
His airplane, a prototype Fokker F.I triplane, serial number 103/17, went into a steep dive and crashed north of Frezenberg, Belgium. Voss was killed.
Major James Thomas Byford McCudden, V.C., D.S.O. and Bar, M.C. and Bar, M.M., one of the British pilots involved in the dogfight, later said of Voss,
“As long as I live I shall never forget my admiration for that German pilot, who single-handed fought seven of us for ten minutes and also put some bullets through all our machines. His flying was wonderful, his courage magnificent, and in my opinion he was the bravest German airman whom it has been my privilege to see fight.”

The Fokker F.I was a prototype single-engine, single-seat triplane fighter, designed and built by Fokker Flugzeugwerke GmbH, Schwerin, Germany. After very slight changes, the production version would be designated Fokker Dr.I. The fuselage was constructed of steel tubing braced with wire and covered with fabric. The wings used plywood ribs and a boxed plywood spar.
The F.I was 5.770 meters (18 feet, 11.2 inches) long. The upper wing had a span of 7.190 meters (23 feet, 7.1 inches); the middle wing, 6.225 meters (20 feet, 5 inches); and the lower wing, 5.725 meters (18 feet, 9.4 inches). All three wings had a chord of 1.000 meters (3 feet, 3.4 inches). The airplane had an overall height of 2.950 meters (9 feet, 8.1 inches). Its empty weight was 405 kilograms (893 pounds), and the gross weight was 587 kilograms (1,294 pounds).

Originally built with a Motorentfabrik Oberursel Ur.II nine-cylinder rotary engine rated at 110 horsepower (a license-built copy of the French Le Rhône 9J engine), Werner Voss had an actual Le Rhône 9J, serial number J6247, installed to replace the Ur.II.
The Le Rhône 9J, produced by Société des Moteurs Le Rhône, was an air-cooled, normally aspirated, 15.074 liter (919.85 cubic inches) nine-cylinder rotary engine, capable of producing 113 horsepower at 1,200 r.p.m., and a maximum 135 horsepower at 1,350 r.p.m. As the engine rotated, it turned a two-bladed Axial Proppellerwerk AG fixed-pitch, laminated wood propeller with a diameter of 2.660 meters (8 feet, 8.7 inches). The Le Rhône 9J was 850 millimeters (2 feet, 9.47 inches) long and 970 millimeters (3 feet, 2.19 inches) in diameter. It weighed 137 kilograms (302 pounds).
The Fokker F.I had a maximum speed of 185 kilometers per hour (115 miles per hour) at Sea Level and 166 kilometers per hour (103 miles per hour) at 4,000 meters (13,123 feet ). The service ceiling was 7,000 meters (22,966 feet). It carried fuel for approximately 1½ hours of flight.
The F.I was armed with two fixed 8mm Spandau LMG 08/15 machine guns, synchronized to fire forward through the propeller arc. The fighter carried 550 rounds of ammunition per gun.
Werner Voss’ triplane, 103/17 (Wn. 1730), was a prototype, Versuch 5, or V5, ordered on 14 July 1917 and accepted by the German Air Force on 16 August. It was sent to Jagdstafell 10 on 21 August.
A British intelligence officer who examined the wreckage of Voss’ Fokker F.I described it as having camouflaged green upper surfaces and blue lower surfaces. Photographs of 103/17 show painted eyes and a mustache on the engine cowling, which are believed to have been inspired by Japanese kites that Voss had flown as a child.
Leutnant Werner Voss had been awarded the famous Pour le Mérite (the “Blue Max”), Germany’s highest award; the Hausorden von Hohenzollern (the Cross of the Order of the Royal House Order of Hohenzollern with Crown and Swords); and the Eisernes Kreuz (Iron Cross), 1st and 2nd Class.

Lieutenant (j.g.) David S. Ingalls, USN, France, 1918. (U.S. Navy)
20 September 1918: While assigned to No. 213 Squadron, Royal Air Force, Lieutenant (junior grade) David Sinton Ingalls, United States Navy, shot down a Fokker D.VII reconnaissance airplane near Vlissegham, Belgium, while flying a Sopwith Camel, serial number D8177. This was Ingalls’ fifth confirmed aerial victory, making him the U.S. Navy’s only fighter ace of World War I.
Lieutenant Ingalls was awarded the Navy Cross for his actions of 15 September 1918, when “he led a flight of five machines on a low bombing raid of an enemy aerodrome. On the homeward journey he shot down a two-seater enemy aeroplane in flames. He further participated in two other low bombing raids and upon still another occasion shot down an enemy kite balloon in flames near Ostend.” He was also awarded the Distinguished Service Medal for exceptionally meritorious service. The Royal Air Force awarded him its Distinguished Flying Cross for the 15 September mission against Uytkerke Aerodrome, and he was Mentioned in Dispatches. France appointed him Chevalier de la légion d’honneur.
Sopwith Camel F.1. (Royal Air Force)
The Sopwith Camel F.1 was a British single-place, single-engine biplane fighter, produced by the Sopwith Aviation Co., Ltd., Canbury Park Road, Kingston-on-Thames. The airplane was constructed of a wooden framework, with the forward fuselage being covered with aluminum panels and plywood, while the aft fuselage, wings and tail surfaces were covered with fabric.
The length of the Camel F.I varied from 18 feet, 6 inches (5.639 meters) to 19 feet, 0 inches (5.791 meters), depending on which engine was installed. Both upper and lower wings had a span of 28 feet, 0 inches (8.534 meters) and chord of 4 feet, 6 inches (1.372 meters). They were separated vertically by 5 feet (1.524 meters) at the fuselage. The upper wing had 0° dihedral, while the lower wing had 5° dihedral and was staggered 1 foot, 6 inches (0.457 meters) behind the upper wing. The single-bay wings were braced with airfoil-shaped streamline wires. The overall height of the Camel also varied with the engine, from 8 feet, 6 inches (2.591 meters) to 8 feet, 9 inches (2.667 meters).
The heaviest Camel F.I variant used the Le Rhône 180 h.p. engine. It had an empty weight of 1,048 pounds (475 kilograms). Its gross weight of 1,567 pounds (711 kilograms). The lightest was equipped with the Gnôme Monosoupape 100 horsepower engine, with weights of 882 pounds (400 kilograms) and 1,387 pounds (629 kilograms), respectively.
Front view of a Sopwith Camel F.I
The first Camel was powered by an air-cooled 15.268 liter (931.72 cubic inches) Société Clerget-Blin et Cie Clerget Type 9 nine-cylinder rotary engine which produced 110 horsepower at 1,200 r.p.m. and drove a wooden two-bladed propeller. Eight different rotary engines ¹ from four manufacturers, ranging from 100 to 180 horsepower, were used in the type.
The best performance came with the Bentley B.R.1 engine (5.7:1 compression ratio). This variant had a maximum speed of 121 miles per hour (195 kilometers per hour) at 10,000 feet (3,048 meters), and 114.5 miles per hour (184 kilometers per hour) at 15,000 feet (4,572 meters). It could climb to 6,500 feet (1,981 meters) in 4 minutes, 35 seconds; to 10,000 feet (3,048 meters) in 8 minutes, 10 seconds; and 15,000 feet (4,572 meters) in 15 minutes, 55 seconds. It had a service ceiling of 22,000 feet (6,706 meters). Two other Camel variants could reach 24,000 feet (7,315 meters).

The Bentley B.R.1 rotary engine was designed by Lieutenant Walter Owen Bentley, Royal Naval Air Service (later, Captain, Royal Air Force), based on the Clerget Type 9, but with major improvements. It used aluminum cylinders shrunk on to steel liners, with aluminum pistons. The Bentley B.R.1 (originally named the Admiralty Rotary, A.R.1, as it was intended for use by the Royal Navy) was an air-cooled, normally-aspirated 17.304 liter (1,055.9 cubic inches) nine-cylinder rotary engine with a compression ratio of 5.7:1. It was rated at 150 horsepower at 1,250 r.p.m. The B.R.1 was 1.110 meters (3 feet, 7.7 inches) long, 1.070 meters (feet, 6.125 inches) in diameter and weighted 184 kilograms (406 pounds.) The engine was manufactured by Humber, Ltd., Coventry, England.
For his work developing this engine, Captain Bentley was appointed a Member of the Military Division of the Most Excellent Order of the British Empire (M.B.E.) in the New Years Honours List, 1 January 1919. He would later found Bentley Motors, Ltd.
The Camel was armed with two fixed, forward-firing .303 Vickers machine guns, synchronized to fire forward through the propeller. These guns were modified for air cooling. Some night fighter variants substituted Lewis machine guns mounted above the upper wing for the Vickers guns. Four 25 pound (11.3 kilogram) bombs could be carried on racks under the fuselage.

The Sopwith Camel was a difficult airplane to fly. Most of its weight was concentrated far forward, making it unstable, but, at the same time making the fighter highly maneuverable. The rotary engine, with so much of its mass in rotation, caused a torque effect that rolled the airplane to the right to a much greater degree than in airplanes equipped with radial or V-type engines. A skilled pilot could use this to his advantage, but many Camels ended upside down while taking off.
Twelve manufacturers ² produced 5,490 Sopwith Camels between 1916 and 1920. By the end of World War I, it was becoming outclassed by newer aircraft, however it was the single most successful fighter of the war, shooting down 1,294 enemy aircraft. One single fighter, flown by Major William Barker, shot down 46 enemy aircraft, more than any other fighter in history.
It is believed that only seven Sopwith Camels still exist.
Lieutenant David Sinton Ingalls, Naval Reserve Flying Corps, circa 1919. (U.S. Naval Institute)
David Sinton Ingalls was born 28 January 1899 at Cleveland, Ohio. He was the son of Albert Stimson Ingalls, a vice president of the New York Central Railroad, and Jane Ellison Taft Ingalls, niece of President William Howard Taft. He was educated at the University School, a private school for boys in Cleveland. He entered Yale University at New Haven, Connecticut, in 1916. Ingalls was a member of The First Yale Unit, which would become the U.S. Navy’s first aviation unit.
Shortly after the United States entered World War I, David Sinton Ingalls enlisted as a Machinist’s Mate 1st Class, United States Naval Reserve Force, at New London, Connecticut, 26 March 1917. He was sent to the Naval Aviation Detachment at West Palm Beach, Florida, for initial flight training, and then to the Naval Aviation Detachment, Huntington, New York. MM1c Ingalls was discharged 1 September 1917 and appointed an Ensign, 4 September 1917. He was Naval Aviator Number 85.
Ensign Ingalls was sent to France for duty, 12 September 1917. In December 1917, he was detached and sent to the Royal Flying Corps air station at Turnberry, South Ayrshire, Scotland, for training in aerial gunnery. He then underwent squadron formation training at nearby Ayr, Scotland. Following training, Ensign Ingalls was assigned to the Naval Air Detachment at Paris, France, 12 March 1918. On 23 March 1918, Ingalls was promoted to the rank of Lieutenant (junior grade).
On 21 May 1918, Lieutenant (j.g.) Ingalls was assigned to the U.S. Army Bombing School at Clermont-Ferrand, France. On 27 June 1918, Lieutenant (j.g.) Ingalls was assigned to the Naval Air Station Dunkerque. He flew combat missions with No. 213 Squadron, and No. 218 Squadron, both of the Royal Air Force. (While flying with the 218th, he was reported to have shot down an observation balloon and a biplane. The records were lost and these claims are considered unconfirmed.)
While flying with No. 213 Squadron, on 11 August 1918, Lieutenant (j.g.) Ingalls shot down an Albatros C northeast of Diksmuide, West Flanders—his first confirmed victory. His second confirmed victory was a two-place Luftverkehrsgesellschaft m.b.H. (L.V.G.) biplane south of Zevecote, Belgium, on 21 August. He shot down a Rumpler C over Ostend, 15 September. His fourth confirmed victory took place on 18 September when he destroyed an observation balloon at La Barrière. The Fokker D.VII that he shot down on 20 September was his fifth. He shot down his sixth,a Rumpler, on 24 September 1918, over Saint-Pierre-Cappelle, Belgium. Other than the Fokker D.VII, Ingalls shared credit with other pilots for the shoot-downs.
Lieutenant (j.g.) Ingalls flew his final combat mission, his sixty-third, on 3 October 1918.
On 24 September 1919, he was given the provisional rank of Lieutenant, Naval Reserve Flying Corps, with date of rank, 1 April 1919. He was released from active duty 23 December 1919.
Returning to Yale University, he graduated in 1920 with a Bachelor of Arts degree, and in 1923, received a Doctor of Laws (LL.D.) degree from Harvard University, Cambridge, Massachusetts. He practiced law for several years before being elected to the state legislature of Ohio in 1926. Later, he ran for governor and United States senator.
David Sinton Ingalls married Miss Louise Hale Harkness at Locust Valley, New York, 27 June 1922. They would have five children: Edith, Jane, Anne, Louise, and David.

On 24 December 1931, Ingalls was appointed a Lieutenant Commander, United States Naval Reserve.
Going to work in the business sector, Ingalls became vice president and general manager of Pan American Air Ferries, a commercial transport service from the United States to Egypt, and which also transported newly-built military aircraft from the United States via South America, across the South Atlantic Ocean to Africa, and then on to the Middle East.
Lieutenant Commander Ingalls was promoted to Commander, U.S.N.R., 1 July 1941, and following the United States entry into World War II, he was recalled to active duty, 23 November 1942. Commander Ingalls served as Assistant Operations Officer on the staff of the Commander, Naval Air Forces, Pacific, (COMNAVAIRPAC), for which he was awarded the Legion of Merit. He was promoted to Captain, 10 June 1943. He then served as chief of staff to the Commander Aircraft South Pacific Force, Admiral Aubrey W. Fitch, USN.
Captain Ingalls took command of U.S. Naval Air Station 29 (now, Daniel K. Inouye International Airport—HNL—Honolulu, Hawaii) on 1 April 1944.
Captain Ingalls was released from active duty 8 November 1945, but he remained an officer in the Naval Reserve. Ingalls returned to Pan American World Airways as vice president, and remained in that position until 1949. Later, he was president and publisher of the Cincinnati Times-Star newspaper, and a vice president of Taft Broadcasting Company.

Captain Charles Barbin DeBellevue, U.S. Air Force, with his F-4D Phantom II at Udorn RTAFB, 1972. (U.S. Air Force)
9 September 1972: Captain Charles Barbin DeBellevue, United States Air Force, a Weapons System Officer flying on F-4D and F-4E Phantom II fighters, became the high-scoring American Ace of the Vietnam War when he and his pilot, Captain John A. Madden, Jr., shot down two Mikoyan-Gurevich MiG 19¹ fighters of the Không Quân Nhân Dân Việt Nam (Vietnam People’s Air Force), west of Hanoi.
Captain DeBellevue was assigned to the 555th Tactical Fighter Squadron, 432nd Tactical Reconnaissance Wing, at Udorn Royal Thai Air Force Base. With Captain Richard S. Ritchie, he had previously shot down four MiG 21 fighters using AIM-7 Sparrow radar-guided missiles. Then while flying a combat air patrol in support of Operation Linebacker, he and Captain Madden, aboard F-4D-29-MC Phantom II 66-0267, call sign OLDS 01, used two AIM-9 Sidewinder heat-seeking missiles to destroy the MiG 19s. These were Madden’s first two aerial victories, but for DeBellevue, they were number 5 and 6.
Mikoyan-Gurevich MiG 19
Madden and DeBellevue had fired two AIM-7 Sparrow radar-guided missiles at a MiG-21 which was on approach to land at the Phúc Yên Yen air base northwest of Hanoi, but both missiles missed. The MiG was then shot down by gunfire from an F-4E flown by Captain Calvin B. Tibbett and 1st Lieutenant William S. Hargrove (after two of their missiles also missed). The flight of Phantoms was then attacked by MiG 19s. DeBellevue reported:
We acquired the MiGs on radar and positioned as we picked them up visually. We used a slicing low-speed yo-yo to position behind the MiG-19s and started turning hard with them. We fired one AIM-9 missile, which detonated 25 feet from one of the MiG-19s. We then switched the attack to the other MiG-19 and one turn later we fired an AIM-9 at him.
I observed the missile impact the tail of the MiG. The MiG continued normally for the next few seconds, then began a slow roll and spiraled downward, impacting the ground with a large fireball. Our altitude was approximately 1,500 feet at the moment of the MiG’s impact.

The first MiG-19, damaged by the Sidewinder’s close detonation, crashed on the runway at Phuc Yen.
After becoming the war’s highest-scoring American ace, Chuck DeBellevue was sent to Williams Air Force Base, Arizona, for pilot training. He became an aircraft commander of F-4E Phantom IIs. He retired from the Air Force as a colonel in 1998, after 30 years of service.
DeBellevue’s F-4D, 66-0267, was destroyed by Hurricane Andrew in 1992. It was reassembled with parts from other damaged Phantoms and is on display as a “gate guard” at Homestead Air Force Base, Florida.
F-4D-29-MC 66-7463, in which he scored his first and fourth kills with Steve Ritchie, is on display at the United States Air Force Academy. Like DeBellevue, this airplane is also credited with 6 victories. DeBellevue’s F-4E-36-MC, 67-0362, in which he and Ritchie shot down their second and third MiG 21s, was sold to Israel in 1973.
