29 September 1954: At Edwards Air Force Base in the high desert of southern California, McDonnell Aircraft Corporation test pilot Robert C. Little made the first flight of the first F-101A-1-MC Voodoo, 53-2418. During this flight, the new interceptor reached 0.9 Mach at 35,000 feet (10,668 meters).

The F-101A was a development of the earlier McDonnell XF-88 Voodoo and all were production aircraft. There were no prototypes.

Robert C. Little flew P-51 Mustang fighters during World War II. He joined McDonnell Aircraft Corporation as a test pilot in 1948. He flew the FH Phantom, and made the first flights of the F3H Demon, the F-101A Voodoo and the F-101B. He was next assigned as McDonnell’s chief test pilot and base manager at Edwards Air Force Base. He the made the first flight of the YF4H-1 Phantom II and conducted the early company tests of the airplane, then became the F4H program manager.

Outside the cockpit, Little rose through the company’s ranks and after the merger with Douglas, became a corporate vice president, overseeing the operations of McDonnell-Douglas at St. Louis and McDonnell-Douglas Helicopters at Mesa, Arizona.

The McDonnell F-101A Voodoo was a single-seat twin-engine supersonic interceptor. It was 67 feet, 5 inches (20.549 meters) long with a wingspan of 39 feet, 8 inches (12.090 meters) and overall height of 18 feet (5.486 meters). The total wing area was 368 square feet (34.19 square meters). The wings’ sweep was 36° 36′ at 25% chord. The angle of incidence was 1°. There was no twist or dihedral. The F-101A weighed 24,970 pounds (11,326 kilograms) empty and had maximum takeoff weight of 49,998 pounds (22,679 kilograms).

Power was supplied by two Pratt & Whitney J57-P-13 axial-flow turbojet engines. The J57 was a two-spool axial flow turbojet which had a 16-stage compressor (9 low- and 7 high-pressure stages), and a 3-stage turbine (1 high- and 2 low-pressure stages). The J57-P-13 maximum continuous power rating of 8,700 pounds of thrust (38.70 kilonewtons); military power, 10,200 pounds (45.37 kilonewtons) (30-minute limit); and 15,000 pounds (66.72 kilonewtons) with afterburner (5 minute limit). The -P-13 was  3 feet, 4.3 inches (1.024 meters) in diameter, 17 feet, 7.0 inches (5.359 meters) long, and weighed 5,025 pounds (2,279 kilograms).

The F-101A had a maximum speed of 866 knots (997 miles per hour/1,604 kilometers per hour) at 35,000 feet (10,668 meters). Its service ceiling was 45,800 feet (13,960 meters). The airplane’s combat radius was 1,011 nautical miles (1,163 statute miles/1,872 kilometers). The maximum ferry range was 2,541 nautical miles (2,924 statute miles/4,706 kilometers)

The Voodoo was armed with four 20mm M39 autocannons with 200 rounds of ammunition per gun. It could carry a single Mark 7, Mark 28 or Mark 43 tactical nuclear bomb.

Of 807 F-101 Voodoos built, 77 were F-101As.

F-101A 53-2418 was transferred to General Electric for testing the J79 afterburning turbojet engine which would later power the McDonnell F-4 Phantom II. In this configration it was designated NF-101A. General Electric returned the Voodoo to the Air Force in 1959. By that time obsolete, it was used as a maintenance trainer at Shepard Air Force Base, Texas.

53-2418 was next turned over to a civilian aviation maintenance school and assigned a civil registration number by the Federal Aviation Administration, N9250Z. The airplane was sold as scrap, but was purchased by Mr. Dennis Kelsey. In 2009, Mrs. Kelsey had the airplane placed in the care of the Evergreen Aviation and Space Museum, McMinnville, Oregon. After being partially restored by Evergreen Air Center, Marana, Arizona, 53-2418 was placed on display at the Evergreen Museum.

Tabeling, at Perth, Western Australia. These officers are wearing the U.S. Navy’s distinctive Aviation Working Green uniform. (FAI)

29 September–1 October 1946: The third production Lockheed P2V-1 Neptune, Bureau of Aeronautics serial number (Bu. No.) 89082, departed Perth, Western Australia, enroute to the United States, non-stop. The aircraft commander was Commander Thomas D. Davies, United States Navy. Three other pilots, Commanders Eugene P. Rankin and Walter S. Reid, and Lieutenant Commander Roy H. Tabeling, completed the crew.

The purpose of the flight was to demonstrate the long-distance capabilities of the Navy’s new bomber. A memorandum from Chief of Naval Operations, Fleet Admiral Chester A. Nimitz, to the Secretary of the Navy suggested:

“For the purpose of investigating means of extension of present patrol aircraft ranges, physiological limitations on patrol plane crew endurance and long-range navigation by pressure pattern methods, it is proposed to make a nonstop flight of a P2V-1 aircraft from Perth, Australia, to Washington, D.C., with the possibility, weather permitting, of extending the flight to Bermuda.”

The Lockheed Aircraft Corporation P2V Neptune was a twin-engine, long-range patrol bomber normally operated by a crew of eight. The first production variant, the P2V-1, was 75 feet, 4 inches (22.962 meters) long with a wingspan of 100 feet (30.48 meters) and overall height of 28 feet, 6 inches (8.687 meters). Empty weight was 33,720 pounds (15,295 kilograms) and gross weight was 61,153 pounds (27,739 kilograms).

The P2V-1 Neptune was powered by two air-cooled, supercharged, 3,347.66-cubic-inch-displacement (54.858 liter) Wright Aeronautical Corporation Cyclone 18 779C18BB1  (R-3350-8), two-row 18-cylinder radial engines (also known as the Duplex-Cyclone). These engines were rated at 2,100 horsepower at 2,400 r.p.m., at Sea Level, and 2,400 horsepower at 2,600 r.p.m for takeoff. They drove four-bladed propellers through a 0.4375:1 gear reduction. The R-3350-8 was 6 feet, 5.8 inches (1.976 meters) long, 4 feet, 6.12 inches (12.375 meters) in diameter and weighed 2,796 pounds (1,268 kilograms)

These engines gave the P2V-1 a maximum speed of 303 miles per hour (488 kilometers per hour) at 15,300 feet (4,663 meters). The service ceiling was 27,000 feet (8,230 meters) and range was 4,110 miles (6,614 kilometers).

Standard armament consisted of six .50-caliber machine guns, two torpedoes carried in the internal bomb bay, conventional bombs or up to twelve depth charges. Nuclear weapons could also be carried. Sixteen rockets could be carried under the wings.

The Turtle was modified by Lockheed to achieve the maximum possible range. All armament was deleted, including the nose gun turret. Additional fuel tanks were installed in the bomb bay, rear fuselage and the outer wings. Wing tip fuel tanks were also added. These could be jettisoned when empty to reduce weight and aerodynamic drag. Most electronic and other unnecessary equipment, such as crew oxygen, were also removed. An additional lubricating oil tank for the engines was installed in the nose gear bay.

The standard configuration R-3350-8 engines were replaced with two Wright Cyclone 18 779C18BB2s (R-3350-14). The -14 had the same normal power rating as the -8, but its takeoff power had been decreased to 2,300 horsepower at 2,800 r.p.m. Its propeller gear reduction was 0.5625:1. The dimensions were the same, but the -14 weighed 65 pounds (29 kilograms) less.

Four Jet Assisted Take Off (JATO) rockets were added, with two on each side of the fuselage.

The flight began at Pearce Aerodrome, six miles inland from the Indian Ocean, north of Perth, Western Australia. Because of concerns that the landing gear might collapse with the extreme overloaded condition, The Turtle was only partially fueled when it taxied to Runway 27. Once there, the fueling was completed, bringing the Neptune’s all-up weight to 85,561 pounds (38,810 kilograms)—24,408 pounds (11,071 kilograms)—12 tons beyond its normal gross weight.

At 6:00 p.m., the two Cyclone 18 engines were started and warmed up. With Commander Davies flying in the left seat and Commander Rankin in the right, the engines were advanced to takeoff power while Davies stood on the brakes. With instruments reading normal, he released the brakes and The Turtle began its takeoff roll. The time was 6:11 p.m., local.

As indicated airspeed reached 87 knots (100 miles per hour/161 kilometers per hour) the four JATO rockets were fired. Reaching 115 knots (132 miles per hour/213 kilometers per hour) the nose wheel lifted off the runway followed a few seconds later by the main wheels. With just 5 feet (1.5 meters) altitude, the landing gear was retracted. By the time the JATOs burned out, the P2V-1 had climbed to 20 feet (6 meters) and reached 130 knots. (150 miles per hour/241 kilometers per hour) Once over the Indian Ocean the four JATO rockets were jettisoned.

This was the heaviest takeoff by a two-engine airplane up to that time.

The overweight airplane very slowly gained altitude as it crossed over Australia and then the Coral Sea. The planned route was a Great Circle Course over New Guinea and then the Solomon Islands.

With four pilots aboard, the crew rotated positions every two hours.

By dawn of the second day airborne, The Turtle crossed over the Hawaiian Islands chain at Maro Reef, between Midway and Oahu. Headwinds were pushing the patrol bomber southward of the intended course, but Commander Davies elected to allow the airplane to drift as correcting for it would have slowed their flight by turning more directly into the wind and would use more fuel. The planned route would have crossed the West Coast of the United States near Seattle, Washington, but the actual landfall was several hundred miles to the south, along the northern California coast.

The empty wing tip tanks were jettisoned before they crossed the shoreline just north of San Francisco at 9:16 p.m., 30 September.

As The Turtle flew across the Sierra Nevada and Rocky Mountains, and the western United States, it encountered severe weather with turbulence, freezing rain, snow and ice. They passed Salt Lake City, Utah, at dawn of the third day. Weather conditions had improved.

The adverse weather had cost additional fuel and calculations indicated that the planned destination of Washington, D.C., was now beyond their range. Commander Davies decided that the flight would end at NAS Columbus, Ohio.

The Lockheed Neptune’s wheels touched down at 1:28 p.m, 1 October. The four Naval Aviator’s and their bomber had flown 18,081.99 kilometers (11,235.63 miles). This set a new Fédération Aéronautique Internationale (FAI) World Record for Distance in a Straight Line Without Landing.¹ The duration of the flight was 55 hours, 17 minutes.

Secretary of the Navy James V. Forrestal awarded each pilot the Distinguished Flying Cross.

P2V-1 Bu. No. 89082 was used as a test aircraft until it was retired in 1953 and put on display at NAS Norfolk, Virginia.

The last operational antisubmarine warfare flight by a Lockheed Neptune, an SP-2H, was flown 20 February 1970. The co-pilot on the mission was Rear Admiral Thomas D. Davies.

The Turtle, Lockheed P2V-1 Neptune Bu. No. 89082 is a part of the collection of the Smithsonian Institution National Air and Space Museum. It is on loan to the National Naval Aviation Museum, NAS Pensacola, Florida.

Note on the name of the airplane: The Turtle was named after Operation Turtle,  a joint U.S. Navy/Lockheed project to maximize the range and endurance of the P2V Neptune patrol bomber. The name with a cartoon of a turtle with a naval officer’s cap and a cape, smoking a pipe and pedaling to turn a propeller was painted on the airplane’s nose. U.S. Navy press releases called it “The Truculent Turtle” and newspapers picked up this nickname, by which the airplane is generally referred to. There is no evidence that the airplane’s crew ever described the airplane as “truculent”:

“. . . having a bad state of mind, or behaving in a threatening manner. . . .”

29 September 1931

Supermarine S.6B S.1595 at the London Science Museum

29 September 1931: After waiting all day for the fog to clear, at 5:49 p.m., Flight Lieutenant George Hedley Stainforth of the Royal Air Force High-Speed Flight at RAF Calshot, made a 43-second takeoff run and began an attempt to set a new Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 3 Kilometer Course. ¹ His airplane was a Supermarine S.6B, number S.1595, the same seaplane that won the Coupe d’Aviation Maritime Jacques Schneider race on 13 September.

The High-Speed Flight had originally intended to use the second S.6B, S.1596, fitted with a specially-prepared Rolls-Royce Type R engine, for the 3 kilometer record attempt. S.1596 had been damaged on landing after a test flight, 16 September. While being towed back to RAF Calshot, the airplane sank. Fortunately, the special speed record engine, number R27, was not installed in S.1596 at the time of the accident.

Supermarine S.6B S.1595

Supermarine S.6B S.1595 had engine R27 installed, along with a new airscrew provided by Fairey Aviation Company Ltd. Also new was the fuel mixture of “wood alcohol” (methanol), gasoline and ethanol, being used in the engine for the first time.

During the speed runs, the High-Speed Flight squadron engineering officer flew along the course at an altitude of 400 meters, carring a sealed barograph. This would later be used to calibrate the time measurements.

The course was flown between Hill Head and Lee-on-Solent, on the Hampshire shoreline, with Flight Lieutenant Stainforth making four runs, two in each direction, to minimize the effect of winds.

The runs were:

Run 1: 415.2 miles per hour (668.2 kilometers per hour)

Run 2: 405.1 miles per hour (651.9 kilometers per hour)

Run 3: 409.5 miles per hour (659.0 kilometers per hour)

Run 4: 405.4 miles per hour (652.4 kilometers per hour)

Average: 408.8 miles per hour (657.9 kilometers per hour)

The official record time as published by the FAI is 655 kilometers per hour (407 miles per hour). George Stainforth was the first pilot to fly faster than 400 miles per hour.

ROYAL AIR FORCE.

     The KING has been graciously pleased to approve the award of the Air Force Cross to the undermentioned officers of the Royal Air Force :—

Flight Lieutenant John Nelson Boothman.

In recognition of his achievement in winning the Schneider Trophy Contest, 1931.

Flight Lieutenant George Hedley Stainforth.

In recognition of his flights with the High Speed Flight of the Royal Air Force in connection with the Schneider Trophy Contest, 1931, culminating in the establishment of a world’s speed record on 29th September, 1931.

Flight, No. 1193 (Vol. XXIII, No. 45), Thursday, November 6, 1931 at Page 1110, Column 1.

S.1595 was Vickers-Supermarine S.6B Monoplane, designed by Reginald Joseph Mitchell, who would later design the legendary Supermarine Spitfire fighter of World War II. The racer was developed from Mitchell’s earlier S.4, S.5 and S.6 Schneider Cup racers, and was built at the Supermarine Aviation Works (Vickers), Ltd., Southampton, on the south coast of England. There were two S.6Bs, with the second identified as S.1596.

The Supermarine S.6B was a single-place, single-engine, low-wing monoplane with two fixed pontoons as an undercarriage. It was of all-metal construction and used a high percentage of duralumin, a very hard alloy of aluminum and copper, as well as other elements. The float plane was 28 feet, 10 inches (8.788 meters) long, with a wingspan of 30 feet, 0 inches (9.144 meters) and height of 12 feet, 3 inches (3.734 meters). The wing area was 145 square feet (13,5 square meters). The S.6B had an empty weight of 4,560 pounds (2,068 kilograms) and gross weight of 5,995 pounds (2,719 kilograms).

In an effort to achieve the maximum possible speed, aerodynamic drag was eliminated wherever possible. There were no radiator or oil cooler intakes. The wing surfaces were constructed of two thin layers of duralumin with a very small space between them. The engine coolant, a mixture of water and ethylene glycol, was circulated between these layers, which are known as surface radiators. The engine had a high oil consumption rate and the vertical fin was the oil supply tank. The skin panels also served as surface radiators. The fuselage panels were corrugated for strength, and several small parallel passages transferred lubricating oil from the fin tank to the engine, and further cooled the oil.

Rolls-Royce Type R SOHC 60° V-12 racing engine. (FLIGHT)

For the 3 kilometer record, S.1595 was powered by a liquid-cooled, supercharged, 2,239.327-cubic-inch-displacement (36.696 liter) Rolls-Royce Type R single-overhead-camshaft (SOHC) 60° V-12 engine, number R27. The Type R was a racing engine with 4 valves per cylinder and a compression ration of 6:1. In the 1931 configuration, it produced 2,350 horsepower at 3,200 r.p.m. It used a 0.605:1 reduction gear and turned a forged duralumin Fairey Aviation fixed-pitch airscrew with a diameter of 8 feet, 6 inches (2.591 meters). R27 weighed 1,630 pounds (739 kilograms).

There would have been no 1931 British Schneider Trophy Race team without the generous contribution of Lucy, Lady Houston, D.B.E., who donated £100,000 to Supermarine to finance the new aircraft. Lady Houston would later sponsor the 1933 Houston Mount Everest Flying Expedition.

The record-setting aircraft, S.1595, is in the collection of the Science Museum, London.

George Hedley Stainforth was born at Bromley, Kent, in 23 March 1899, the son of George Staunton Stainforth, a solicitor, and Mary Ellen Stainforth.

Stainforth was a graduate of the Royal Military Academy Sandhurst. On 11September 1918, Cadet Stainforth was commissioned a Second Lieutenant of Infantry, East Kent Regiment (“The Buffs”), ³ effective 21 August 1918 and served in France. On 30 March 1923, Lieutenant Stainforth, R.A.R.O., was granted a short service commission as a Flying Officer, Royal Air Force, effective 15 March 1923.

Flying Officer Stainforth married Miss Gladys Imelda Hendy at St. George’s Hanover Square Church, London, in March 1923.

Stainforth was promoted to Flight Lieutenant, 3 July 1928. He was granted a permanent commission in this rank 1 October 1929.

In 1929, Stainforth won the King’s Cup Air Race, and on 10 September, set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 3 Kilometer Course, averaging 541.10 kilometers per hour (336.22 miles per hour) while flying a Gloster Napier 6 powered by a Napier Lion VIID broad arrow W-12 engine.

Stainforth was promoted to Squadron Leader with effect from 1 June 1936. On 12 March 1940, he was promoted to the rank of Wing Commander, with effect from 1 March 1940.

During World War II, Wing Commander Stainforth commanded No. 89 Squadron in Egypt. The New York Times reported that he was “the oldest fighter pilot in the Middle East.” On the night of 27–28 September 1942, while flying a Bristol Beaufighter near the Gulf of Suez, Wing Commander George Hedley Stainforth, A.F.C., was killed in action. He was buried at the Ismailia War Memorial Cemetery, Egypt.
