Fokker Trimotor
Long-range aircraft of the 1920s
By Stephen Sherman, Apr. 2007. Updated July 23, 2011.
The sub-zero Arctic wind penetrated
the unheated, ungainly, three-motor airplane taking off from Spitsbergen. Inside, navigator Richard
Byrd, an ambitious U.S. Navy Commander, and pilot Floyd Bennett
struggled to keep warm in their furs. They reported that they reached
the North Pole on May 9, 1926, a claim which many have questioned.
Their airplane, the Fokker Trimotor, seems always to
have been involved
in various controversies. It was designed and built by the brilliant
and opportunistic Anthony Fokker, a Dutch engineer, who perfected the
synchronized machine gun for the Germans in World War One, and after
the war, promptly began doing business in America.
The origin of the Fokker Trimotor F.VII, lay in the F.2. A high-wing
monoplane with a fully enclosed cabin, the F.2 was revolutionary in
1920.
By 1926, the Fokker F.VII Trimotor had emerged: 49 feet long, with a
wingspan of 63 feet, it weighed 6,8000 pounds empty (less than two
modern Ford Explorer SUVs). It was constructed of mixed materials:
metal tubing, fabric for the fuselage, and wooden wings. Built by
Fokker's company, Netherlands Aircraft Manufacturing Corporation, at a
cost of $40,000 each, altogether 42 were built. Powered by three Wright
Whirlwind, 200-horsepower radial engines, the Trimotor's top speed was
118 MPH.
Configured to carry 2-pilots and 10-passengers, it could fly as far as
1,600 miles (at cruising speed, under good conditions). Because
of its long range for the time, many long-distance aviators of
the late 1920's used the Fokker Trimotor on their transoceanic,
transcontinental, and polar flights. The variant produced for the US
Army was the C-2.
Byrd's plane on his Arctic flight, nicknamed the "Josephine Ford," for
sponsor Edsel's daughter, bore the word "FOKKER" in huge letters on
wings and fuselage, so that no one would confuse his aircraft for a
FORD Trimotor.
The Southern Cross
Another famous Fokker Tri-Motor was the "Southern Cross," flown by
two
aviators, Hubert Wilkins and later, Charles Kingford-Smith.
In early 1926, Wilkins flew from Fairbanks, Alaska to Point Barrow and
back, a flight which required flying over the 11,000-ft Endicott Range.
A modified C-2, with a wingspan of 72-ft, the "Southern Cross"
was the first long-wing Fokker produced. It carried 700 gallons of
gasoline, 45-gal of oil, enabling the long flight to Point Barrow and
then some local aerial exploring. The craft was damaged during three
test flights at Fairbanks, but was
repaired and ended up in the possession of Charles
Kingsford-Smith, an Australian aviator, known as "Smithy."
Smithy, flying the Southern Cross, on May 31, 1928, took off from San
Francisco for Hawaii and then went on to Brisbane, a total of 7,316
miles. The Fokker F-VIIB was tested on the flight by stormy weather and
broken navigational equipment, and several times the aircraft came
close to going down. But the crew of four made it, and
Kingsford-Smith’s became Australia’s greatest aviation hero.
It later flew practically around the world where it became famous from
its
name Southern Cross. This historic tri-motor is now on display in
Melbourne, Australia.
The America
After his 1926 flight over the North Pole, then-Commander Richard E.
Byrd, was not happy with simply being the leader of the first flight
over the North Pole. In February 1927, Floyd Bennett, Byrd's partner
and co-pilot on the North Pole flight, announced the intention to
attempt to win the 'Orteig Prize', the $25,000 reward offered for the
first successful non-stop flight from New York City to Paris. He and
Byrd, with their strong financial backing, seemed heavy favorites.
Byrd picked a familiar aircraft, the Fokker C-2 monoplane, very
similar to the Fokker F.VII used on his Arctic flight. The C-2 had
three reliable 220hp Wright J-5 engines, the necessary range and plenty
of room for scientific instruments. During a test flight on April 16,
1927, the America crashed on take-off at Hasborough, New Jersey,
injuring three of the four aboard. Byrd fractured his wrist,
Bennett suffered a broken leg and collarbone, and serious head
injuries; George O. Noville, the plane's flight and fuel engineer,
endured an operation to remove a blood clot. With Bennett hospitalized,
Byrd was sought a replacement, delaying the anticipated flight.
At Tony Fokker's suggestion, Byrd selected Bernt Balchen, a Norwegian
test pilot, and former member of Roald Amundsen's airship expedition to
the North Pole.
On May 11th, following the disappearance of Nungesser and Coli,
the Byrd group announced a delay until the French fliers' fate could be
determined. Not long thereafter Lindbergh stole a march on them,
and took
off for Paris on May 20, 1927, landing 33 hours later, claiming the
Orteig
Prize and world renown. Making the best he could of the
situation, Byrd noted the valuable training and scientific experience
to be gained in a transatlantic flight, and continued his
preparations.
Early on June 29, 1927, the "America" took off from Roosevelt Field for
Paris, with a crew of 4 under the command of then-Commander
Richard E. Byrd. Also aboard were Bert Acosta and Bernt Balchen
as relief pilots and Lieutenant George O. Noville.
While Byrd had delayed take-off awaiting ideal weather, the flight was
marred by terrible flying weather. Off Newfoundland, Acosta
accidentally lost control of the aircraft, sending her down towards the
sea. A last-moment correction from Balchen saved the ship and
crew from the cold waters. On another occasion, Noville's feet became
tangled in the wiring of the radio set. Through rainy clouds and strong
winds, the "America" flew east, with Byrd scribbling repeatedly in his
diary, "Impossible to navigate". At regular intervals, the plane's
position was tracked, but as the plane approached France, the compass
begun to malfunction. After a flight of over forty hours, the
airplane reached Paris, but
could not land due to heavy fog, even after 6 hours. Balchen flew
the plane 150 miles back to the west and, low on fuel, forced a water
landing 300 yards off Normandy. The monoplane sunk and settled in the
water up to its wings, but Balchen saved the lives of the crew, who
rowed to shore in a rubber life raft.
The French Navy secured the airframe with several boats, and hauled the
"America" closer to shore, whereupon souvenir hunters quickly
stripped the fuselage down to its steel frame. The three engines were
recovered to prevent further damage from saltwater. The crew remained
in the village of Ver-sur-Mer for one night and left for Paris the next
day. The French people welcomed and honored the four-man
crew; Byrd was named to the Legion d'Honneur of France.
Back in America, both Byrd and Noville were also awarded the
Distinguished Flying Cross.
Bird of Paradise
The door to the Pacific had opened in June, 1928, with the flight of
U.S. Army Air Corps officers Lester J. Maitland and Albert F.
Hegenberger, in a Fokker Trimotor called the 'Bird of Paradise'
(identical to Richard Byrd’s America), from San Francisco to Honolulu,
Hawaii. Maitland and Hegenberger could not put down along the way
and had no landmarks to guide them along the twenty-four-hundred
miles of featureless ocean. The successful flight was a tribute
to the piloting skills of Maitland, the navigating
skills of Hegenberger, and the reliability of the Whirlwind engines and
the Fokker aircraft.
The South Pole
In 1929, Byrd mounted a large expedition to Antarctica with the goal
of
flying over the South Pole. It is sometimes forgotten that since
Amundsen and Scott had made their historic treks in 1911, no one had
returned to the Pole in the next twenty year. On this trip, Byrd's team
included 80 men, dozens of dogs, and three airplanes, including a
Fokker Trimotor, the "South Pole." Bernt Balchen again
accompanied him, but the aircraft met an ignominious end, being wrecked
in a windstorm. Byrd and Balchen flew over the South Pole in their Ford
Trimotor on November 29, 1929.
Military Service
The U.S. Army Air Corps bought three trimotor aircraft from Fokker in 1926, designated the Fokker C-2, essentially an improved version of the F-VIIA, including upgraded 220-hp Wright J-5 engines. (Shown at left.) One was converted to an airborne radio test lab. Various communications and navigation equipment was installed. (Also pictured.)
Commercial Service
In the late Twenties, the Fokker Trimotor was one of the preferred
commercial airliners. When the fatal crash of famed football coach
Knute Rockne's plane in 1931 was traced to rot in the Fokker Trimotor's
wooden wings, that marked the end of the aircraft's popularity, and the
next generation of commercial airliners (the Boeing 247 and Douglas
DC-3) were developed.
