The Fokker F.IV was built by Anthony Fokker’s Nederlandse Vliegtuigenfabriek at Veere, Netherlands in 1921. The Air Service purchased two and designated the type T-2, with serial numbers A.S. 64233 and A.S. 64234.

Several modifications were made to prepare for the transcontinental flight. Normally flown by a single pilot in an open cockpit, a second set of controls was installed so that the airplane could be controlled from inside while the two pilots changed positions. On this flight, it carried 735 gallons (2,782 liters) of gasoline in three fuel tanks.

For its time, the Fokker was a large airplane: 49 feet (14.9 meters) long, with a wing span of 82 feet (25 meters). The high-wing monoplane was powered by a 1,649.3-cubic-inch-displacement (27.028 liter) liquid-cooled Liberty L12 single overhead cam (SOHC) 45° V-12 engine producing 420 horsepower. The airplane was designed to carry 8–10 passengers in an enclosed cabin.

From 2–3 May 1923, MacReady and Kelly succeeded in their non-stop transcontinental flight, flying from Roosevelt-Hazelhurst Field, Long Island, New York, to Rockwell Field (now, NAS North Island), San Diego, California,  2,470 miles (3,975 kilometers) in 26 hours, 50 minutes, 38.8 seconds, for an average speed of 92 miles per hour (148 kilometers per hour).

The U.S. Army Air Service transferred A.S. 64223 to the Smithsonian Institution in January 1924. It is on display at the National Air and Space Museum.

5–6 October 1922: Lieutenants John Arthur Macready and Oakley George Kelly, Air Service, United States Army, set an unofficial world endurance record for an unrefueled airplane when they flew a Fokker T-2, Air Service serial number A.S. 64233, for 35 hours, 18 minutes, 30 seconds at San Diego, California.

The Fokker F.IV was built by Anthony Fokker’s Nederlandse Vliegtuigenfabriek at Veere, Netherlands, in 1921. The Air Service purchased two and designated the type T-2, with serial numbers A.S. 64233 and A.S. 64234.

The Fokker F.IV was a single-engine, high-wing monoplane with fixed landing gear. It was flown by a single pilot in an open cockpit which was offset to the left of the airplane’s centerline. The airplane was designed to carry 8–10 passengers in an enclosed cabin. The F.IV was a scaled-up version of the preceding F.III. It was built of a welded tubular steel fuselage, covered with three-ply plywood. The wing structure had plywood box spars and ribs, and was also covered with three-ply plywood.

For its time, the Fokker was a large airplane. Measurements from the Fokker T-2 at the Smithsonian Institution are: 49 feet, 10 inches (15.189 meters) long, with a wing span of 80 feet, 5 inches (24.511 meters), and height 12 feet, 2 inches (3.708 meters). On this flight, it carried 735 gallons (2,782 liters) of gasoline in three fuel tanks.

The Fokker F.IV was offered with a choice of engines: A Rolls-Royce Eagle IX V-12, Napier Lion II “broad arrow” W-12, or Liberty L-12 V-12. The T-2 was powered by a water-cooled, normally-aspirated, 1,649.336-cubic-inch-displacement (27.028 liter) Ford-built Liberty L-12 single overhead cam (SOHC) 45° V-12 engine with a compression ratio of 5.4:1. (Serial number A.S. No. 5142) The Liberty produced 408 horsepower at 1,800 r.p.m. The L-12 as a right-hand tractor, direct-drive engine. Installed on A.S. 64233, the engine turned turned a two-bladed Curtiss fixed-pitch walnut propeller with a diameter of 10 feet, 5 inches (3.175 meters). The Liberty 12 was 5 feet, 7.375 inches (1.711 meters) long, 2 feet, 3.0 inches (0.686 meters) wide, and 3 feet, 5.5 inches (1.054 meters) high. It weighed 844 pounds (383 kilograms).

The airplane had a maximum speed of 93 miles per hour (150 kilometers per hour), a range of 2,550 miles (4,104 kilometers) and a service ceiling of 10,500 feet (3,200 meters).

Several modifications were made to prepare the T-2 for a transcontinental flight. Normally flown by a single pilot in an open cockpit, a second set of controls was installed so that the airplane could be controlled from inside while the two pilots changed positions. The standard airplane had a 130 gallon (492 liter) fuel tank in the wing. The Army added a 410 gallon (1,552 liter) tank to the wing center section, and a 185 gallon (700 liter) tank in the passenger cabin.

Macready and Oakley planned to fly the T-2 across the North American continent, non-stop, from San Diego, California to New York. The starting point at Rockwell Field was chosen to take advantage of favorable westerly winds, and to use the higher-octane gasoline which was available in California.

When they encountered fog in the mountains east of San Diego, the two fliers were forced to turn back. They remained airborne over San Diego to measure the airplane’s performance and fuel consumption for another attempt. Because the airplane was not equipped with a barograph to record air pressure on a paper chart, the record endurance flight could not be officially recognized by the Fédération Aéronautique Internationale (FAI). They were awarded the Mackay Trophy for the most meritorious flight of the year. This was Macready’s second Mackay. He and Kelly would win it again the following year.

Macready and Oakley made a second unsuccessful attempt to cross the continent from west-to-east, and were finally successful on an east-to-west flight in 1923.

Fokker T-2 A.S. 64233 is in the permanent collection of the Smithsonian Institution National Air and Space Museum.

17–18 June 1928

Fokker F.VIIb/3m Friendship on Southampton Water, after the transatlantic flight.

17–18 June 1928: Amelia Mary Earhart became the first woman to cross the Atlantic Ocean by air when she accompanied pilot Wilmer Lower Stultz and mechanic Louis Edward Gordon as a passenger aboard the Fokker F.VIIb/3m, NX4204, Friendship. The orange and gold, float-equipped, three-engine monoplane had departed from Trepassey Harbor, Newfoundland and Labrador, Canada, and arrived at Burry Port, on the southwest coast of Wales, 20 hours, 40 minutes later.

Amelia Earhart wrote 20 hrs. 40 min.—Our Flight in the Friendship (G.P. Putnam’s Sons, New York, 1928), describing her adventure.

Friendship had been originally ordered by Richard E. Byrd for his Antarctic expedition, but because Ford Motor Company was a major sponsor, he made the decision to switch to a Ford Tri-Motor airplane. Byrd sold the new Fokker to Donald Woodward, heir to the Jell-O Corporation, for $62,000, and it was registered to his Mechanical Science Corp., of Le Roy, New York. Woodward then leased the airplane to Mrs. Frederick Edward Guest (née Anne T. Phipps, also known as Amy Phipps) for her to cross the Atlantic Ocean by air. She chose the name Friendship for the airplane.

Amy Phipps Guest

Mrs. Guest was a daughter of Henry Phipps, Jr., an American industrialist. She was married to Captain the Right Honourable Frederick Edward Guest P.C., C.B.E., D.S.O., M.P., a prominent British politician, former Secretary of State for Air, and a member of His Majesty’s Most Honourable Privy Council. Amy Phipps Guest, however, was a multi-billionaire in her own right.

Mrs. Guest was not a pilot, so Stultz and Gordon had been hired to fly the airplane. When her family ruled out her transoceanic journey, “an American girl of the right type” was selected to make the flight in her place. Miss Amelia Mary Earhart, a social worker living in Boston, was interviewed and was the candidate selected.

Although Earhart was a pilot with approximately 500 hours of flight experience, she did not act as a pilot on this flight. She was, however, the aircraft commander. Instructions from Mrs. Guest’s attorney, David T. Layman, to Stultz and Gordon, dated 18 May 1928, were very specific on this matter:

“This is to say that on arrival at Trepassey of the tri-motor Fokker plane “FRIENDSHIP” if any questions of policy, procedure, personnel or any other question arises the decision of Miss Amelia M. Earhart is to be final. That she is to have control of the plane and of the disposal of the services of all employees as fully as if she were the owner. And further, that on arrival of the plane in London full control of the disposition of the plane and of the time and services of employees shall be hers to the same extent until and unless the owner directs otherwise.”

— The Sound of Wings by Mary S. Lovell, St. Martin’s Press, New York, 1989, Chapter 11 at Page 104.

It was during the planning for this flight that Earhart first met her future husband, George Palmer Putnam.

Though Friendship was equipped with aluminum pontoons for water takeoffs and landings, it was otherwise the same type as Southern Cross, the airplane that Sir Charles E. Kingsford Smith flew from the United States to Australia earlier in the month. It was built by Anton H.G. Fokker’s N. V. Nederlandsche Vliegtuigenfabriek at Veere, Netherlands, in early 1928. Friendship , serial number 5028, was the fourth aircraft in the series. Flown by Bernt Balchen, it made its first flight 16 February 1928.

The Fokker F.VIIb/3m is a three-engine high-wing passenger transport with fixed landing gear. It could carry up to 8 passengers. The airplane was was 14.6 meters (47.9 feet) long, with a wingspan of 21.7 meters (71.2 feet) and 3.9 meters (12.8 feet) high. The wing had an area of 67 square meters (721 square feet). Its empty weight was 3,050 kilograms (6,724 pounds) and the gross weight, 5,200 kilograms (11,464 pounds).

The F.VIIb/3m was powered by three 787.26-cubic-inch-displacement (12.90 liter) air-cooled Wright Aeronautical Corporation Model J-5C Whirlwind nine-cylinder radial engines. The left engine was serial number 8229, the center, 8280, and the right engine, 8321. These were direct-drive engine with a compression ratio of 5.1:1. The J-5C was rated at 200 horsepower at 1,800 r.p.m., and 220 horsepower at 2,000 r.p.m. They drove two-bladed Standard adjustable-pitch propellers. The Wright J-5C was 2 feet, 10 inches (0.864 meters) long and 3 feet, 9 inches (1.143 meters) in diameter. It weighed 508 pounds (230.4 kilograms).

The standard F.VIIb/3m had a cruise speed of cruise 170 kilometers per hour (106 miles per hour), and maximum speed of 190 kilometers per hour (118 miles per hour). Its service ceiling was 4,750 meters (15,584 feet). It had a normal range of 1,240 kilometers (771 miles). NX4204 was modified at Fokker’s American subsidiary, Atlantic Aircraft Corporation in Teterboro, New Jersey, increasing the total fuel capacity to 870 gallons (3,293 liters).

Friendship was sold to José Roger Balet of Argentina in May 1929, and renamed 12 de Octubre, the date of an important national holiday. On 21 June 1931, the airplane was on a commercial flight from Santiago de Chile to Mendoza when it made an emergency landing in Alto Sierra. It was acquired by General Enrique Bravo for the Fuerza Aérea Nacional, November 1931.

The ultimate fate of the airplane is uncertain. Sources indicate that it was removed from service and salvaged for parts after June 1932. Other sources indicate that it was destroyed by accident or fire in September 1934.

Their aircraft was a Fokker F.VIIa/3m three-engine, high-wing monoplane, construction number 600. The airplane was It was purchased for the Byrd Arctic Expedition by Edsel Ford, and named Josephine Ford in honor of his 3-year-old daughter, Josephine Clay Ford.

For this accomplishment, Lieutenant Commander Byrd was promoted to Commander, and Chief Bennett to Warrant Officer. Both aviators were awarded the Medal of Honor by President Coolidge.

In the years since this event, there has been speculation that the airplane may not have actually reached the North Pole. Professor Gerald Newsom of Ohio State University, an astronomer who taught celestial navigation, analyzed Byrd’s handwritten notes and estimated that because of the inadequacies of the equipment then available to Byrd, Josephine Ford may have flown 21 miles (33.8 kilometers) beyond the North Pole, or fallen 78 miles (125.5 kilometers) short. Professor Newsom pointed out, though, that the fact the Byrd was able to return to Svalbard after nearly 16 hours proves that he knew how to navigate using that equipment under those conditions.

Josephine Ford is the first Fokker F.VIIa/3m monoplane, c/n 600. It was built by Anton H.G. Fokker’s N.V. Koninklijke Nederlandse Vliegtuigenfabriek Fokker at Veere, Netherlands in 1925, and made its first flight at Schipol, 4 September 1925. It was demonstrated for Koninklijke Luchtvaart Maatschappij N.V. (KLM, Royal Dutch Airlines), then disassembled and shipped to the United States. 600 was flown from New York to Detroit, where it participated in the First Annual Aerial Reliability Tour, 28 September–3 October 1925, flown by Egbert P. Lott. The airplane was evaluated by the U.S. Army Air Corps at Wright Field, and was then sold to Edsel Ford.

The United States did not register aircraft prior to 1927. According to the Federal Aviation Administration’s Registry data base, FOKKER VII (TRI-MOTOR) Serial Number 600 was registered 21 June 1927 to the Ford Motor Company, Dearborn, Michigan, as NC267. The registration was cancelled 14 March 1930.

Sources vary as to the actual dimensions of the Fokker F.VIIa/3m. The Henry Ford, the museum which owns the airplane, gives its dimensions as 49.167 feet (14.986 meters) in length, with a wingspan of 63.5 feet (19.355 meters) and height of 12.75 feet (3.886 meters). Another source says that the airplane is 47 feet, 11 inches (14.605 meters) long with a wingspan of 63 feet, 4 inches (19.304 meters) and height of 12 feet, 8 inches (3.861 meters). Its empty weight is variously given as 4,630 pounds, 5,060 pounds or 6,724 pounds and maximum takeoff weight is 7,950 pounds, 8,800 pounds or 11,464 pounds. It has a cruise speed of 81 knots. Or 90. . . .

Josephine Ford was powered by three air-cooled 787¼-cubic-inch-displacement (12.901 liter) Wright Aeronautical Corporation Model J-4 Whirlwind nine-cylinder radial engines, rated at 215 horsepower at 1,800 r.p.m. The J-4 weighed 475 pounds. (The specific variant, J-4, J-4A, or J-4B, is not known.)

Josephine Ford is in the collection of The Henry Ford Museum, Dearborn, Michigan.

2–3 May 1923: Air Service, United States Army, pilots Lieutenant John Arthur Macready and Lieutenant Oakley George Kelly made the first non-stop transcontinental flight. Their airplane was a Nederlandse Vliegtuigenfabriek Fokker T-2 single-engine monoplane, U.S. Army serial number A.S. 64233.

The two aviators took off from Roosevelt-Hazelhurst Field, Long Island, New York, at 12:30 p.m., Eastern Time, and landed at Rockwell Field (now, NAS North Island), San Diego, California, the next day at 12:26 p.m., Pacific Time. They had flown 2,470 miles (3,975 kilometers) in 26 hours, 50 minutes, 38.8 seconds, for an average speed of 91.996 miles per hour (148.053 kilometers per hour).

Macready and Kelly had made two previous attempts, flying West-to-East to take advantage of prevailing winds and the higher octane gasoline available in California. The first flight was terminated by weather, and the second by engine failure.

The Fokker F.IV was built by Anthony Fokker’s Nederlandse Vliegtuigenfabriek at Veere, Netherlands, in 1921. The Air Service purchased two and designated the type T-2, with serial numbers A.S. 64233 and A.S. 64234.

Several modifications were made to prepare the T-2 for the transcontinental flight. Normally flown by a single pilot in an open cockpit, a second set of controls was installed so that the airplane could be controlled from inside while the two pilots changed positions. Additional fuel tanks were installed in the wing and cabin.

The Fokker F.IV was a single-engine, high-wing monoplane with fixed landing gear. It was flown by a single pilot in an open cockpit which was offset to the left of the airplane’s centerline. The airplane was designed to carry 8–10 passengers in an enclosed cabin. The F.IV was a scaled-up version of the preceding F.III. It was built of a welded tubular steel fuselage, covered with three-ply plywood. The wing structure had plywood box spars and ribs, and was also covered with three-ply plywood.

For its time, the Fokker was a large airplane. Measurements from the Fokker T-2 at the Smithsonian Institution are: 49 feet, 10 inches (15.189 meters) long, with a wing span of 80 feet, 5 inches (24.511 meters), and height 12 feet, 2 inches (3.708 meters). On this flight, it carried 735 gallons (2,782 liters) of gasoline in three fuel tanks. When it took off from Long Island, the gross weight of the T-2 was 10,850 pounds (4,922 kilograms), only a few pounds short of its maximum design weight.

John Macready and Oakley Kelley won the 1923 Mackay Trophy for this flight. Macready had previously won the award in 1921 and 1922. He is the only pilot to have won it three times.

During testing to determine the feasibility of the flight, on 16–17 April 1923, Lieutenant Kelly and Lieutenant Macready set six Fédération Aéronautique Internationale (FAI) World Records for speed, distance and duration, flying the Fokker T-2. At Wilbur Wright Field, Dayton, Ohio, they flew 2,500 kilometers (1,553.428 miles) at an average speed of 115.60 kilometers per hour (51.83 miles per hour); 3,000 kilometers (1,864.114 miles) at 115.27 kilometers per hour (71.63 miles per hour); 3,500 kilometers (2,174.799 miles) at 114.82 kilometers per hour (71.35 miles per hour); 4,000 kilometers (2,485.485 miles) at 113.93 kilometers per hour (70.79 miles per hour); flew a total distance of 4,050 kilometers (2,517 miles); and stayed aloft for 36 hours, 4 minutes, 34 seconds. Their overall average speed was 112.26 kilometers per hour (69.76 miles per hour) seconds.

The United States Army transferred Fokker T-2 A.S. 64223, to the Smithsonian Institution in January 1924. It is on display at the National Air and Space Museum.
