Captain Richard Stephen Ritchie, United States Air Force
28 August 1972: Captain Richard Stephen Ritchie, United States Air Force, and Weapons System Officer Captain Charles Barbin DeBellevue, leading Buick flight with their McDonnell F-4D Phantom II, shot down a North Vietnamese MiG 21 interceptor. This was Ritchie’s fifth confirmed aerial combat victory, earning him the title of “ace.” [Chuck DeBellevue would later be credited with six kills.]
An official U.S. Air Force history reads:
. . . Ritchie flew the lead aircraft of a MiGCAP flight, with Capt. Charles B. DeBellevue as his WSO, during a Linebacker strike mission. “We acquired a radar lock-on on a MiG 21 that was head-on to us,” Ritchie said.
“We converted to the stern and fired two AIM-7 missiles during the conversion. These missiles were out of parameters and were fired in an attempt to get the MiG to start a turn. As we rolled out behind the MiG, we fired the two remaining AIM-7s. The third missile missed, but the fourth impacted the MiG. The MiG was seen to explode and start tumbling toward the earth. The kill was witnessed by Captain John Madden, aircraft commander in number 3.

“It was an entirely different situation,” Ritchie noted to newsmen. The MiG flew at “a much higher altitude than any of my other MiG kills and at a much greater range. I don’t think the MiG pilot ever really saw us. All he saw were those missiles coming at him and that’s what helped us finally get him.”
The new ace complimented the ground crews who kept the F-4s combat ready: “There’s no way could have done it without them,” he said. In fact, I got my first and fifth MiG in the same plane. Crew Chief Sergeant Reggie Taylor was the first one up the ladder when the plane landed and you just couldn’t believe how happy he was. I think he was more excited than I.”
DeBellevue, whose total victories rose to four with this day’s kill, commented on the teamwork: “The most important thing is for the crew to work well together,” he said. “They have to know each other. I know what Steve is thinking on a mission and can almost accomplish whatever he wants before he asks. I was telling him everything had to know when he wanted it, and did not waste time giving him useless data.”

21 August 1944:¹ The first of two Grumman XF8F-1 Bearcat prototypes, Bu. No. 90460, made its first flight at Bethpage, New York, with Grumman’s Chief Engineer and test pilot Robert Leicester Hall at the controls. The Bearcat was a light-weight high performance interceptor, designed to operate from the U.S. Navy’s smaller aircraft carriers. It used an air-cooled, supercharged, 2,804.4-cubic-inch-displacement (45.956 liter) Pratt & Whitney Double Wasp 2SC13-G (R-2800-22) two-row, 18-cylinder radial engine, an uprated version of the engine used in its predecessor, the Grumman F6F Hellcat.
The R-2800-22 engine was rated at 1,700 horsepower at 2,600 r.p.m. at Sea Level, and 2,100 horsepower at 2,800 r.p.m., for takeoff and Military Power. In order to use the engine’s power more effectively, the prototype Bearcat used a 12-foot, 4-inch (3.759 meter) diameter, four-bladed Aero Products, Inc., propeller, driven through a 0.45:1 gear reduction.
The Bearcat was 20% lighter than the Hellcat. It was 50 miles per hour faster and had a much higher rate of climb.
For aircraft carrier operations, the new fighter could not sacrifice structural strength. In order to limit the weight, armament was reduced to four .50-caliber machine guns, and fuel capacity was also less than that of the Hellcat, giving it reduced range.

The production F8F-1 Bearcat was 27 feet, 6 inches (8.382 meters) long with a wingspan of 35 feet, 6 inches (10.820 meters) and overall height of 13 feet, 10 inches (4.216 meters) (to tip of propeller, in three-point position). With its wings folded, the width of the Bearcat was reduced to 23 feet, 9½ inches (7.252 meters).
The Bearcat’s wings are sharply tapered. Their angle of incidence is −1½°, and there is 5° 30′ dihedral. The leading edges are swept aft 5° 5′. The chord decreases from 9 feet, 7.87 inches (2.943 meters) at the root to 4 feet, 3.5 inches (1.308 meters) at a point 6 inches (15.24 centimeters) inboard from the tip. The total wing area is 244 square feet (22.7 square meters).
The fighter’s horizontal stabilizer has a span of 15 feet, 9 inches (4.801 meters) and a total area of 52.2 square feet (4.85 square meters). Its angle of incidence is +½°. The rudder has a height of 6 feet, 1–13/16 inches (1.875 meters). The vertical tail has a total area of 20.8 square feet (1.93 square meters), and is offset 2° left.
The F8F-1’s empty weight was 7,070 pounds (3,207 kilograms) and maximum takeoff weight was 12,947 pounds (5,873 kilograms). The F8F-2’s empty weight increased to 7,650 pounds (3,470 kilograms), and its maximum takeoff weight was 13,460 pounds (6,105 kilograms).

The production F8F-1 was powered by a Pratt & Whitney Double Wasp 2SC14-G (R-2800-34W) engine which had the same Sea Level power ratings as the R-2800-22. It produced 1,500 horsepower at 2,600 r.p.m. at 18,500 feet (5,639 meters) and had a Military Power rating of 1,700 horsepower at 2,800 r.p.m. at 16,000 feet (4,877 meters). The gear reduction drive ratio was also 0.45:1. A slightly larger Aero Products propeller with a diameter of 12 feet, 7 inches (5.835 meters) was installed. The R-2800-34W was 6 feet, 2.134 inches (1.883 meters) long, 4 feet, 4.80 inches (1.341 meters) in diameter and weighed 2,358.5 pounds (1,069.8 kilograms).
The F8F-2 was powered by a Pratt & Whitney R-2800-30W. The Normal Power rating increased to 1,720 horsepower at 2,600 r.p.m. at Sea Level, and 1,450 horsepower at 22,000 feet (6,706 meters). Takeoff and Military Power also increased: 2,250 horsepower at 2,800 r.p.m. at Sea Level, and 1,600 horsepower at 22,000 feet (6,706 meters). The R-2800-30W also drove an Aero Products propeller. The gear reduction ratio was the same. Its dimensions were slightly different than the -34W: 7 feet, 8.75 inches (2.356 meters) long, and 4 feet, 5.00 inches (1.346 meters) in diameter. The engine’s weight increased to 2,560 pounds (1,161 kilograms).

The Bearcat had a top speed of 336 knots (387 miles per hour/622 kilometers per hour) at Sea Level, and 388 knots (447 miles per hour/719 kilometers per hour) at 28,000 feet (8,534 meters). The airplane had initial rate of climb at Sea Level of 4,465 feet per minute (22.68 meters per second) and it could climb to 20,000 feet (6,096 meters) in 8.4 minutes. Its ceiling was 38,200 feet (11,643 meters).
Fuel capacity is 185 U.S. gallons (700 liters). The fighter’s range could be extended with a jettisonable centerline and two underwing tanks. The Bearcat’s combat radius was 235 nautical miles (270 statute miles/435 kilometers). Its maximum range, with three external tanks (350 gallons/1,325 liters), was 1,595 nautical miles (1,835 statute miles/2,954 kilometers).
The F8F-1 Bearcat was armed with four Browning AN-M2 .50-caliber machine guns. Inboard guns were provided with 325 rounds of ammunition, each, while the outboard guns had 200 rounds per gun. The F8F-2 replaced these with four M3 20 mm autocannon. Each inboard cannon had 325 rounds per gun, and the outboard guns had 188 rounds each. The F8F could also be armed with up to three 11.75-inch (29.845 centimeters) Tiny Tim air-to-ground rockets, or four 5-inch (12.7 centimeter) High Velocity Aerial Rockets (HVAR). For bombing missions, the Bearcat could carry one 1,600 pound (726 kilograms) bomb on the centerline and two 1,000 pounders (454 kilograms, each) under the wings.
The first prototype Grumman XF8F-1 Bearcat, Bu. No. 90460, crashed into Chesapeake Bay during gunnery tests at NAS Patuxent River, Maryland, 18 March 1945. Its pilot was missing, presumably killed. The airplane has recently–probably—been located.²

20 August 1955: Colonel Horace A. Hanes, United States Air Force, flew the first North American Aviation F-100C-1-NA Super Sabre, 53-1709, to Mach 1.246 at 40,000 feet (12,192 meters), setting a new Fédération Aéronautique Internationale (FAI) speed record of 1,323.312 kilometers per hour (822.268 miles per hour) over a measured 15-to-25-kilometer course at Edwards Air Force Base, California.¹
This was the first supersonic world speed record. It was also the first speed record set at high altitude. Previously, all speed records were set very close to the ground for measurement purposes, but with ever increasing speeds this practice was becoming too dangerous.
For his accomplishment, Colonel Hanes was awarded the Mackay Trophy.

The North American Aviation F-100C Super Sabre was a single-seat, single-engine swept wing fighter. In addition to its air superiority role, the F-100C was also capable of ground attack.
The F-100C was 47.8 feet (14.57 meters) long (excluding pitot boom) with a wingspan of 38.8 feet (11.83 meters) and overall height of 15.5 feet (4.72 meters). The wings were swept aft 45° at 25% chord. The wings’ angle of incidence was 0° and there was no dihedral or twist. The total wing area was 385 square feet (35.8 square meters). The fighter had an empty weight of 19,197 pounds (8,708 kilograms), and maximum gross weight of 35,618 pounds (16,156 kilograms).
The F-100C was powered by a Pratt & Whitney J57-P-7 engine. The J57 was a two-spool axial-flow turbojet which had a 16-stage compressor section (9 low- and 7 high-pressure stages) and a 3-stage turbine (2 high- and 1 low-pressure stages). Its continuous power rating was 8,000 pounds of thrust (35.586 kilonewtons). The Military Power rating was 9,700 pounds (43.148 kilonewtons) (30-minute limit). Maximum power was 14,800 pounds (43.148 kilonewtons) with afterburner (5-minute limit). The engine was 20 feet, 9.7 inches (6.342 meters) long, 3 feet, 3.9 inches (1.014 meters) in diameter, and weighed 5,075 pounds (2,303 kilograms).

The F-100C had a maximum speed of 756 knots (870 miles per hour/1,400 kilometers per hour) at 35,000 feet (10.668 meters). The service ceiling was 46,900 feet (14,295 meters). The maximum ferry range was 1,630 nautical miles (1,876 statute miles/3,019 kilometers).
The F-100C Super Sabre was armed with four 20 mm M-39 revolver cannon with 200 rounds of ammunition per gun. It could carry 14 unguided 2.75 inch (70 mm) Folding Fin Aerial Rockets in two 7-round pods. It could be loaded with four 1,000-pound, or six 750-pound bombs on underwing hard points. For tactical nuclear strike, the Super Sabre could be armed with a single MK-7 “Special Store.”

After being used in Air Force testing at Edwards Air Force Base, 53-1709 was transferred to the National Advisory Committee for Aeronautics (NACA) High-Speed Flight Station, also located at Edwards AFB. The F-100 was identified as NACA 703 and assigned civil registration N703NA. It was used for variable stability testing at the Ames Flight Research Center, Moffett Field, California, from 4 September 1956 to 2 November 1960, and 11 March 1964 until 21 March 1972. At some point its tail surfaces were upgraded to those of the F-100D series.
Today, the FAI world-record setting F-100C is displayed at the Castle Air Museum, marked as F-100D 55-2879.

Hanes was commissioned as a second lieutenant, Air Corps, United States Army, 1 July 1940. While retaining his permanent rank of second lieutenant, Hanes advanced to the rank of first lieutenant, Army of the United States (A.U.S.), 10 October 1941. He returned to the United States and served with the Air Training Command.
Lieutenant Hanes was promoted to captain, A.U.S. (A.C.), 1 March 1942, and placed in command of a P-47 Thunderbolt squadron based in Florida, the 312th Fighter Squadron, 338 Fighter Group. On 26 November 1942, Hanes was promoted to the rank of major, A.U.S. On 1 July 1943, Hanes was promoted to the permanent rank of first lieutenant, Air Corps, United States Army. He retained this permanent rank until after the war.
Major Hanes was deployed to Europe in August 1943, commanding the 71st Fighter Squadron (Twin Engine), 1st Fighter Group, at Mateur Airfield, Tunisia. The 71st had been the first operational P-38 squadron. After flying 30 combat missions, Major Hanes’ P-38 went down over Yugoslavia in January 1944. For the next three months he evaded capture. Hanes returned to the United States in April 1944 and was assigned to command Punta Gorda Army Airfield, a fighter training base on the western coast of Florida.
Hanes was promoted to lieutenant colonel, A.U.S., 1 August 1944, and to colonel, A.U.S., 23 October 1945. In January 1946, Colonel Hanes assumed command of the 31st Fighter Group, which deployed to Giebelstadt Army Airfield in southwest Germany. The group operated P-51D Mustangs and the new Lockheed P-80B Shooting Star jet fighter. In 1947, Colonel Hanes took command of the 67th Tactical Reconnaissance Group at March Air Force Base, Riverside, California. The 67th was equipped with the Douglas RB-26 Invader and the Lockheed RF-80 Shooting Star.

20 August 1944: Mustang Mk.I AG346, while flying with No. 168 Squadron, Second Tactical Air Force, Royal Air Force, from a forward airfield at Sainte-Honorine-des-Pertes, Normandy, France, was shot down near Gacé by antiaircraft fire.
The very first operational North American Mustang, AG346 (North American serial number 73-3099) was the second airplane to come off the assembly line at Inglewood, California.
After flight testing by North American’s test pilots and Royal Air Force fighter pilots Chris Clarkson and Michael “Red Knight” Crossley, AG346 was crated and then shipped to England, arriving at Liverpool, 24 October 1941. It was taken to the Lockheed facility at Speke Aerodrome (now, Liverpool John Lennon Airport, LPL) where it was reassembled and put through additional performance and flight tests.
AG346 was then assigned to an operational RAF fighter squadron. It served with Nos. 225, 63 and 26 Squadrons before being assigned to No. 41 Operations Training Unit. AG346 was returned to operations with No. 16 Squadron, and finally, No. 168 Squadron.
The Mustang Mk.I was a new fighter built by North American Aviation, Inc., for the Royal Air Force. The RAF had contracted with NAA to design and build a fighter with a liquid-cooled Allison V-1710 12-cylinder engine. The first order from the British Purchasing Commission was for 320 airplanes, and a second order for another 300 soon followed.
The Mustang Mk.I (NAA Model NA-73) was a single-place, single-engine fighter primarily of metal construction with fabric control surfaces. It was 32 feet, 3 inches (9.830 meters) long with a wingspan of 37 feet, 5/16-inches (11.373 meters) and height of 12 feet, 2½ inches (3.721 meters). The airplane’s empty weight was 6,280 pounds (2,849 kilograms) and loaded weight was 8,400 pounds (3,810 kilograms).

The Mustang Mk.I was powered by a liquid-cooled, supercharged 1,710.597-cubic-inch-displacement (28.032 liter) Allison Engineering Company V-1710-F3R (V-1710-39) single overhead camshaft (SOHC) 60° V-12 engine with four valves per cylinder and a compression ratio of 6.65:1. The engine had a takeoff rating of 1,150 horsepower at 3,000 r.p.m. at Sea Level with 45.5 inches of manifold pressure (1.51 Bar), and a war emergency rating of 1,490 horsepower with 56 inches of manifold pressure (1.90 Bar). The Allison drove a 10 foot, 9 inch (3.277 meter) diameter, three-bladed, Curtiss Electric constant-speed propeller through a 2.00:1 gear reduction. The V-1710-39 was 7 feet, 4.38 inches (2.245 meters) long, 3 feet, 0.54 inches (0.928 meters) high, and 2 feet, 5.29 inches (0.744 meters) wide. It weighed 1,310 pounds (594 kilograms).
This engine gave the Mustang Mk.I a maximum speed of 382 miles per hour (615 kilometers per hour) and cruise speed of 300 miles per hour (483 kilometers per hour). The service ceiling was 30,800 feet (9,388 meters) and range was 750 miles (1,207 kilometers).
The Mustang Mk.I was equipped with four Browning .303 Mk.II machine guns, two in each wing, and four Browning AN-M2 .50-caliber machine guns, with one in each wing and two mounted in the nose under the engine.
The British would recommend that the Allison be replaced by the Rolls Royce Merlin V-12. This became the Mustang Mk.III and the U.S.A.A.F. P-51B. Eventually, over 15,000 Mustangs were built, and it was a highly successful combat aircraft. Today, after 71 years, the Mustang is one of the most recognizable of all airplanes.
AG346 was the first one to go to war.
No. 168 Squadron was a reconnaissance unit. Its motto was Rerum cognoscere causas (“To know the cause of things”)

The production F8F-2 used an air-cooled, supercharged, 2,804.4-cubic-inch-displacement (45.956 liter) Pratt & Whitney Double Wasp E12 (R-2800-30W) twin-row 18-cylinder radial engine with a compression ration of 6.75:1. The R-2800-30W was rated at 1,720 horsepower at 2,600 r.p.m. at Sea Level, and 1,450 horsepower at 2,600 r.p.m. at 22,000 feet (6,706 meters). The Takeoff and Military Power ratings were 2,250 horsepower at 2,800 r.p.m. at Sea Level, and 1,600 horsepower at 2,800 r.p.m. at 22,000 feet (6,706 meters). These power ratings required 115/145 aviation gasoline and water/alcohol injection and 115/145 aviation gasoline. The engine drove an Aeroproducts Inc. four-bladed propeller with a diameter of 12 feet, 7 inches (3.835 meters) through a 0.450:1 gear reduction. The R-2800-30W was 8 feet, 2.75 inches (2.508 meters) long, 4 feet, 5.00 inches (1.346 meters) in diameter and weighed 2,560 pounds (1,161.2 kilograms).
The Bearcat had a top speed of 421 miles per hour (677.5 kilometers per hour). It could climb at 4,570 feet per minute (23.2 meters per second) and had a service ceiling of 38,700 feet (11,796 meters). Its range was 1,105 miles (1,778 kilometers).
Conquest I‘s wings were shortened by 7 feet (2.134 meters). The new wingspan is 28 feet, 6 inches (8.687 meters). The R-2800 engine of Greenamyer’s racer was modified to produce 3,100 horsepower. It drove an Aeroproducts propeller from a Douglas AD-6 Skyraider, which had a diameter of 13 feet, 6 inches (4.115 meters). The spinner from a North American Aviation P-51H Mustang was used.
Conquest I is in the collection of the Smithsonian Institution National Air and Space Museum. It was given to the museum by Greenamyer in exchange for an F8F-1 Bearcat, Bu. No. 90446. It is on display at the Steven F. Udvar-Hazy Center, Chantilly, Virginia.
