The Société des Avions Marcel Dassault MD.454 Mystère IV N 01 was the first of two prototype two-place, single-engine, swept-wing interceptors. 01 was first flown 19 July 1954 by test pilot Gérrard Muselli. It had a large air-search radar mounted over the intake and was armed with 52 rockets carried in a retractable tray in the belly, very similar to the North American Aviation F-86D Sabre. The fuselage had been lengthened over the single-seat Mystère IV to provide space for the second cockpit.

The Mystère IV N was 49 feet, 11 inches (15.215 meters) long with a wingspan of 37 feet, 6 inches (11.430 meters) and overall height of 15 feet, 1 inch (4.597 meters). Its empty weight was 15,741 pounds (7,140 kilograms) and maximum takeoff weight was 22,572 pounds (10,238 kilograms).

The Mystère IV N was powered by a Rolls-Royce Avon RA.7R axial flow, afterburning turbojet engine. It used a 12-stage compressor, 8 combustion chambers and 2-stage turbine. It produced 9,500 pounds of thrust (42.258 kilonewtons) at 7,800 r.p.m., with afterburner. The engine was 42.2 inches (1.072 meters) in diameter, 276 inches (7.010 meters) long and weighed 2,960 pounds (1,343 kilograms).

27 May 1958: At Lambert Field, St. Louis, Missouri, McDonnell Aircraft Corporation’s Chief Test Pilot (and future company president) Robert C. Little made the first flight of the YF4H-1 prototype. The twin-engine Mach 2+ airplane was the first pre-production model of a new U.S. Navy fleet defense interceptor that would be developed into the legendary F-4 Phantom II fighter bomber.

The flight lasted 22 minutes. Little had planned to go supersonic but a leak in a pressurized hydraulic line caused him to leave the landing gear extended as a precaution, should the back-up hydraulic system also have a problem. This limited the maximum speed of the prototype to 370 knots (426 kilometers per hour). A post-flight inspection found foreign-object damage to the starboard engine.

Initially designated XF4H-1 and assigned Bureau of Aeronautics serial number (“Bu. No.”) 142259, the identifier was changed to YF4H-1. It had been in development for over five years based on a company proposal to the Navy.

The McDonnell YF4H-1 Phantom II was 56 feet, 7.9 inches (17.271 meters) long with a wingspan of 38 feet, 4.89 inches (11.707 meters) and overall height of 16 feet, 3.0 inches (4.953 meters). With wings folded, the airplane’s span was narrowed to 27 feet, 6.6 inches (8.397 meters). The wings were swept 45° at 25% chord. The inner wing had no dihedral, while the outer panels had 12° dihedral. The stabilator had a span of 16 feet, 5.0 inches (5.004 meters), with -23.25° anhedral. The wheelbase of Phantom II’s tricycle undercarriage was 23 feet, 3.25 inches (7.093 meters), with a main wheel tread of 17 feet, 10.46 inches (5.447 meters).

The YF4H-1 prototype was powered by two General Electric J79-GE-2 engines. These were single-spool, axial-flow turbojet engines with a 17-stage compressor and 3-stage turbine. The J79-GE-2 was rated at 10,350 pounds of thrust (46.039 kilonewtons), and 16,150 pounds (71.389 kilonewtons) with afterburner. The engines were 17 feet, 4.0 inches (5.283 meters) long, 3 feet, 2.3 inches in diameter (0.973 meters), and each weighed 3,620 pounds (1,642 kilograms).

The production F4H-1 (F-4B) had a maximum speed of 845 miles per hour (1,360 kilometers per hour) at Sea Level and 1,485 miles per hour (2,390 kilometers per hour) at 48,000 feet (14,630 meters meters). (Mach1.11 and Mach 2.25, respectively). The service ceiling was 62,000 feet (18,898 meters) and maximum range with external fuel was 2,300 miles (3,700 kilometers).

The second prototype YF4H-1, Bu. No. 142260, flown by Commander Lawrence E. Flint, Jr., USN, set a Fédération Aéronautique Internationale (FAI) World Record for Altitude, 6 December 1959, when it zoom-climbed to 30,040 meters (98,556 feet).¹ On 22 November 1961, flown by Lieutenant Colonel Robert B. Robinson, USMC, 142260 also set an FAI World Record for Speed over a Straight 15/25 Kilometer Course, averaging 2,585.425 kilometers per hour (1,606.509 miles per hour).² On 5 December 1961, the same Phantom set an FAI World Record for Altitude in Horizontal Flight at 20,252 meters (66,444 feet) with Commander George W. Ellis, USN, in the cockpit.³

The F-4A through F-4D Phantoms were armed with four AIM-7 Sparrow radar-homing air-to-air missiles, and could carry additional Sparrows or AIM-9 Sidewinder infrared-homing missiles on pylons under the wings. Up to 16,000 pounds (7,257 kilograms) of bombs could be carried on five hardpoints.

McDonnell Aircraft built two YF4H-1 prototypes, followed by 45 F4H-1F (F-4A) Phantom IIs before the F-4B was introduced in 1961. 649 F-4Bs were produced. The initial U.S. Air Force variant was the F-110A Spectre (F-4C Phantom II). McDonnell Douglas delivered its last Phantom II, an F-4E-67-MC, on 25 October 1979. In 21 years, the company had built 5,057 Phantom IIs.

26 May 1961: The Firefly, the Blériot Trophy-winning Convair B-58A-10-CF Hustler, serial number 59-2451, assigned to the 43rd Bombardment Wing, Carswell Air Force Base, Fort Worth, Texas, set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Recognized Course by flying from Washington, D.C. to Paris in 3 hours, 39 minutes, 49 seconds, for an average speed of 1,687.69 kilometers per hour (1,048.68 miles per hour).¹

During the same flight, the B-58 flew the New York to Paris segment in 3 hours, 14 minutes, 44.53 seconds, at an average speed of 1,753.16 kilometers per hour (1,089.36 miles per hour).

The aircrew, Major William R. Payne, Aircraft Commander, Captain William L. Polhemus, Navigator, and Captain Raymond R. Wagener, Defensive Systems Officer, won the Harmon and Mackay Trophies for this flight.

The B-58A Hustler was a high-altitude Mach 2 strategic bomber which served with the United States Air Force from 1960 to 1970. It was crewed by a pilot, navigator/bombardier and a defensive systems operator, each located in individual cockpits. The aircraft had a delta-winged configuration similar to the Convair F-102A Delta Dagger and F-106 Delta Dart supersonic interceptors. The fuselage incorporates the “Area Rule” which resulted in a “wasp waist” or “Coke bottle” shape for a significant reduction in aerodynamic drag. The airplane’s only control surfaces are two “elevons” and a rudder. There are no flaps.

The “Hustler” was 96.8 feet (29.5 meters) long, with a wing span of 56.8 feet (17.3 meters) and an overall height of 31.4 feet (9.6 meters). The wings’ leading edges were swept back at a 60° angle. The wings had a 3°0′ angle of incidence, 2°14′ dihedral, and a total area of 1,542.5 square feet (143.3 square meters).

The B-58A had an empty weight of 51,061 pounds (23,161 kilograms). Its Maximum Takeoff Weight (MTOW) was 90,000 pounds (40,823 kilograms), but once airborne, it could take on additional fuel from a tanker, raising the bomber’s maximum weight to 125,147 pounds (56,766 kilograms).

The B-58A was powered by four General Electric J79-GE-5 afterburning turbojet engines, suspended under the wings from pylons. These were single-shaft axial-flow engines with a 17-stage compressor and 3-stage turbine. The J79-GE-5 had a continuous power rating of 9,700 pounds of thrust (43.15 kilonewtons), Military Power, 10,000 pounds of thrust (44.49 kilonewtons), and Maximum Power, 15,600 pounds (69.39 kilonewtons) with afterburner. (All ratings at 7,460 r.p.m.) The engine was 16 feet, 10.2 inches (5.131 meters) long and 3 feet, 2.0 inches (0.889 meters) in diameter. It weighed 3,570 pounds (1,619 kilograms).

The bomber had a cruise speed of 626 miles per hour (1,007 kilometers per hour) from 30,000 to 50,000 feet (9,144–15,240 meters), and a maximum speed of 1,319 miles per hour (2,124 kilometers per hour) at 56,100 feet (17,099 meters). The B-58’s service ceiling was 67,200 feet (20,483 meters).

Jet fuel (JP-4) was carried in three tanks inside the airplane’s fuselage, and two tanks in a streamlined drop tank. The total capacity of the five tanks was 15,369 gallons (58,178 liters). Its combat radius was 2,589 miles (4,167 kilometers) and the maximum ferry range was 6,483 miles (10,434 kilometers).

The B-58 weapons load was a combination of W-39, B43 or B61 nuclear bombs. The W-39 was carried in the centerline pod. (A two-component mission pod was also available.) The W-39 was the same warhead used on the PGM-11 Redstone intermediate range ballistic missile and the SM-62 Snark intercontinental cruise missile. It was a two-stage radiation-implosion thermonuclear warhead with an explosive yield of 3.8 megatons. The warhead weighed 6,230 pounds (2,826 kilograms). The B-43 and B-61 bombs were carried on four hardpoints under the fuselage.

There was a defensive General Electric M61 Vulcan 20 mm rotary cannon mounted in the bomber’s tail, with a maximum 1,040 rounds of ammunition. The gun was remotely-controlled by the Defensive Systems Officer.

Captain McMeen was awarded the Distinguished Flying Cross for his achievement.

This same helicopter set a World Record for Altitude Without Payload  at 10,010 meters (32,841 feet), 18 October 1961.² It was flown by Lieutenant Colonel Francis M. Carney over the Kaman plant at Bloomfield. Connecticut. The following week, on 24 October 1961, Colonel Carney set six more world records, flying the HH-43B to 3,000 meters (9,853 feet) in 2 minutes, 41.5 seconds;³ 6,000 meters (19,685 feet) in 6 minutes 49.3 seconds;⁴ and to 9,000 meters (29,528 feet) in 14 minutes, 31 seconds.⁵ Captain Richard H. Coan set a World Record for Distance Over a Closed Circuit Without Landing, when he flew 60-0263 1,055.16 kilometers (655.65 miles), at Mono Lake, California, 13 June 1962.⁶ Captain Chester R. Radcliffe, Jr., set an FAI World Record for Distance Without Landing when he flew the Huskie from Hill Air Force Base, Utah, to Springfield, Minnesota, a distance of 1,429.80 kilometers (888.44 miles), 5 July 1962.⁷

The Kaman Aircraft Corporation Huskie was used by the U.S. Air Force, U.S. Navy and Marine Corps, primarily for short range rescue operations. It was operated by two pilots and two rescue crewmen.

A turboshaft engine drove a unique system of counter-rotating and intermeshing rotors to provide lift, thrust and directional control. The counter-rotation cancelled the torque effect so no anti-torque, or tail, rotor was necessary. This allowed all of the engine’s power to drive the main rotor system.

The fuselage of the H-43B was 25 feet, 2 inches (7.671 meters) long. Each rotor had a diameter of 47 feet, 0 inches (14.326 meters). It’s height was 15 feet, 6½ inches (4.737 meters). The helicopter’s empty weight was 4,470 pounds (2,028 kilograms) and its maximum gross weight was 8,800 pounds (3,992 kilograms).*

The H-43B was powered by one Lycoming T53-L-1B turboshaft engine, rated at 860 shaft horsepower at 21,510 r.p.m. The engine uses a 5-stage axial-flow, 1 stage centrifugal-flow, compressor with a single stage gas producer turbine and single-stage power turbine. A reverse-flow combustion section allows significant reduction in the the engine’s total length. The power turbine drives the output shaft through a 3.22:1 gear reduction. The T53-L-1 is 3 feet, 11.8 inches (1.214 meters) long and 1 foot, 11.0 inches (0.584 meters) in diameter. It weighs 460 pounds (209 kilograms).

The Huskie’s economical cruise speed was 98 miles per hour (158 kilometers per hour), and the maximum speed was 120 miles per hour (193 kilometers per hour). Its hover ceiling out of ground effect (HOGE) was 18,000 feet (5,486 meters), and in ground effect (HIGE) was 20,000 feet (6,096 meters) and it had a range of 235 miles (378 kilometers).

With the call sign Pedro, the HH-43 was a rescue helicopter that served in combat during the Vietnam War.

The record-setting Kaman HH-43B Huskie 60-0263 was last assigned to Detachment 3, 42nd Aerospace Rescue and Recovery Squadron, Kirtland Air Force Base, New Mexico. It is in the collection of the National Museum of the United States Air Force, Wright-Patterson Air Force Base, Ohio.

Walter Carlton McMeen was born 22 July 1926 at Lamesa, Dawson County, Texas,  He was the son of Ralph Evan McMeen, an oil company truck driver, and Nannie Dee Price. At the age of 17 years, Walter enlisted in the United States Navy, 29 March 1944. He served as a fireman aboard the Fletcher-class destroyer USS Young (DD-580). Following World War II, Fireman 1st Class McMeen was released from active duty, 16 May 1946.

McMeen studied at Texas Technological College, Lubbock, Texas, but in 1950, he left school to enlist as an aviation cadet in the U.S. Air Force. He was sent to pilot training at Williams Air Force Base, southeast of Phoenix, Arizona.

Aviation Cadet McMeen married Miss Lena Fay Boykin of Dallas, Texas, at Williams AFB, 28 Oct 1950. The wedding was presided over by an Air Force chaplain. They would have four children.

Walter C. McMeen was commissioned as a second lieutenant, U.S.A.F., 10 February 1951. He flew 100 combat missions in fighter bombers during the Korean War. He then served as an instructor at Nellis AFB, near Las Vegas, Nevada.

Lieutenant McMeen transitioned to the Piasecki H-21. In three years at Nellis, he rescued 49 pilots. He was then assigned to Luke AFB. During the next four years, in addition to 31 Air Force personnel, McMeen rescued 41 civilians and brought them to safety.

In 1955, using an ax to chop through the canopy of a burning North American Aviation F-86 Sabre, Lieutenant McMeen saved the life of the fighter’s pilot. For this action he was awarded the Soldier’s Medal.

On 12 April 1960, Captain McMeen accepted the first Kaman H-43B at the factory in Bloomfield, Connecticut. He flew the new helicopter to Langley, Virginia, where it was loaded aboard a Lockheed C-130 Hercules and transported to Luke AFB, Arizona.

In 1968, Major McMeen commanded Detachment 16, Western Aerospace Rescue and Recovery Center at Williams AFB.

Major McMeen retired from the Air Force 1 July 1970.

McMeen was fatally injured 28 December 1984, at San Diego, California. He was a passenger aboard a Bell 47G-3B-1 helicopter, N474MP, attempting to land aboard M/V Olga del Pacifico, a 70.01-meter, 1,111 gross ton Mexican-registered tuna seiner which was tied up alongside the 10th Avenue Terminal in San Diego Bay. The pilot, James McDonald, did not see a crane boom which was positioned over the ship’s helideck. McDonald was critically injured, but McMeen died at Physicians and Surgeons Hospital at 4:15 p.m.**

Major Walter Carlton McMeen was buried at the National Memorial Cemetery of Arizona, Phoenix, Arizona.

24 May 1948: Two days after setting two Fédération Aéronautique Internationale (FAI) World and U.S. National Aeronautic Association speed records with her P-51B Mustang, Jackie Cochran sets two more.

Flying her “Lucky Strike Green” North American Aviation P-51B-15-NA, serial number 43-24760, civil registration NX28388, Cochran flew an average of 693.780 kilometers per hour (431.094 miles per hour) over a 1,000 kilometer (621.371 miles) closed circuit, without payload, at Santa Rosa Summit, near Indio, California.¹

Screen Shot 2015-01-02 at 12.18.19

Jackie Cochran bought NX28388 from North American Aviation, Inc., 6 August 1946. Cochran also flew the green P-51B in the 1946 and 1948 Bendix Trophy Races, in which she placed 2nd and 3rd. Her Mustang was flown by Bruce Gimbel in the 1947 Bendix race, placing 4th.

The P-51B and P-51C are virtually Identical. The P-51Bs were built by North American Aviation, Inc., at Inglewood, California. P-51Cs were built at North American’s Dallas, Texas plant. They were 32 feet, 2.97 inches (9.829 meters) long, with a wingspan of 37 feet, 0.31-inch (11.282 meters) and overall height of 13 feet, 8 inches (4.167 meters) high. The fighter had an empty weight of 6,985 pounds (3,168 kilograms) and a maximum gross weight of 11,800 pounds (5,352 kilograms).

The P-51B was the first version of the North American Aviation fighter to be powered by the Merlin engine in place of the Allison V-1710. Rolls-Royce had selected the Packard Motor Car Company to build Merlin aircraft engines in the United States under license. NX28388 was powered by a Packard-built V-1650-7, serial number V332415, which was based on the Merlin 66. It was a right-hand tractor, liquid-cooled, supercharged 1,649-cubic-inch-displacement (27.04-liter), single overhead cam (SOHC) 60° V-12 engine, which produced 1,490 horsepower at Sea Level, turning 3,000 r.p.m. at 61 inches of manifold pressure (V-1650-7). (Military Power rating, 15 minute limit.)
