At the
height of the Great Depression, aircraft executive Walter H. Beech
and airplane designer T. A. "Ted" Wells joined forces to collaborate
on a project many considered foolhardy — a large, powerful, and fast biplane
built specifically for the business executive. The Beech Model 17, popularly
known as the "Staggerwing" was first flown on November 4,
1932, setting the
standard for private passenger airplanes for many years to come. It was
considered, during its time, to be the premier executive aircraft flying, much
as the Gulfstream executive jets are considered in contemporary times.

line at the beginning of Staggerwing production (note the fixed landing
gear).
The
Model 17's unusual wing
configuration—the upper wing inversely staggered behind the lower—and unique
shape resulted in a design that maximized the pilot's visibility while
minimizing the aircraft's tendency to stall.
The fabric-covered fuselage was faired with wood formers and stringers placed over a welded, steel tube frame. The
construction of the plane was complex and took many manhours to complete. The
Staggerwing's retractable conventional landing gear, uncommon at
that time, combined with streamlining, lightweight, and its use of powerful radial
engines helped it perform significantly better than other biplane designs.
In the
mid-1930s, Beech embarked upon a major redesign of the aircraft, to be known
officially as the Model D17 Staggerwing. The D17 featured a lengthened fuselage that
improved the aircraft's landing characteristics by increasing the leverage generated
by the elevator. Ailerons were
relocated on the upper wings,
eliminating any interference with the air flow over the flaps.
Braking was
improved by the introduction of a foot-operated brake that was synchronized
with the rudder
pedals. All of these modifications enhanced the Staggerwing's performance,
which would soon be put to the test under wartime conditions.
Sales
started slowly at first; the first Staggerwings' high price tag (between US$14,000 and US$17,000, depending on the size of the
engine) scared off potential buyers in an already depressed market for civil
aircraft. Only 18 Model 17s were sold during 1933,
the first year of production, but sales steadily increased. Each Staggerwing
was custom-built by hand. The luxurious cabin, trimmed in leather and mohair, could hold
up to five passengers. Eventually, the Staggerwing captured a substantial share
of the passenger aircraft market. By the start of World War II, more than 424
Model 17s had been sold.
The
Staggerwing's speed also made it the darling of the air racers of the 1930s. An early
version of Model 17 won the 1933
Texaco Trophy
Race. In 1935, a British diplomat, Capt.
H.L. Farquhar, successfully flew around
the world in a Model B17R, traveling 21,332 miles (34,331 kilometers)
from New York
to London, by
way of Siberia,
Southeast
Asia, the Middle East, North Africa
and back across Europe.
Louise
Thaden and Blanche Noyes won the 1936
Bendix
trophy in a Model C17R Staggerwing. Thaden also won the Harmon
Trophy for her achievement. Jackie
Cochran set a women's speed record of 203.9 mph, established an altitude
record of over 30,000 feet (9.144 meters), and finished third in the 1937
Bendix Trophy Race, all while flying a special Model D17W Staggerwing. The
aircraft made an impressive showing in the 1938
Bendix race as well.
As
World War II loomed on the horizon, a number of Model B17L were pressed into
service by the forces of the Second Spanish Republic as bombers during
the Spanish Civil War. China ordered a
number of Staggerwings to use as ambulance
planes in its fight against Imperial
Japan. Finland
had one B17L as a liaison aircraft between 1940-1945. On October 2, 1941, Beech shipped a
special camouflaged
D17S to Prince Bernhard of Lippe, who was in exile
in London after
the Germany
invasion of The Netherlands. He used it for refugee work in and
around London.
The Beech
UC-43 Traveler was a slightly modified version of the Staggerwing. In late 1938,
three Model D17S were purchased for evaluation by the United States Army Air Corps for
possible use as a light liaison aircraft. These were designated YC-43.
After a short flight test program, the YC-43s were sent to Europe to serve as
liaison aircraft with the air
attachés in London,
Paris and Rome.
Early
in World
War II, the need for a compact executive-type transport or courier aircraft
became apparent and in 1942 the United States Army Air Forces ordered
the first of 270 Model 17s for service within the United
States and overseas as the UC-43. These differed only in minor
details from the commercial model. To meet urgent wartime needs, the government
also purchased or leased
(impressed) additional "Staggerwings" from private owners including
118 more for the Army Air Force plus others for the United States Navy. In Navy service the planes
were designated as GB-1 and GB-2. The British
Royal
Air Force also received 106 "Traveller Mk. I" (the name is
correct with the anglicized double "l") through the Lend-Lease
arrangement to fill its own critical need for light
personnel transports.
The production
UC-43 differed in minor details from the service test YC-43. Two distinguishing
external features of the UC-43 are the circular ADF antenna
mounted between the main landing gear and landing lights
near the lower wingtips.
They were all powered by the 450 horsepower
(336 kilowatt)
Pratt
& Whitney R-985 engine.
After
the war's end, Beech immediately converted its manufacturing capabilities back
to the production of civil aircraft with one final version of the
Staggerwing, the Model G17S. 16 aircraft were built and sold at a price of US$29,000 apiece. One D17S was sold to Finland from Norway in 1949 and
it was used for Finnish Air Force between 1950-1958. The
lightweight V-tail
Beechcraft Bonanza, a high-powered
four-passenger luxury aircraft, soon replaced the venerable Staggerwing in the
Beech product line, at about one-third the price. The Bonanza was a much
smaller aircraft with much less horsepower, but carried four people with almost
exactly the same speed as the Staggerwing. The final Staggerwing was sold in 1948;
it left the factory in 1949, the last of 785 aircraft.
In
March of 2003, Plane & Pilot magazine named the Staggerwing one of
its Top Ten All-Time Favorite aircraft.[1]
