21 January 1937: Iris Louise McPhetridge Thaden set a U.S. national record flying her Consolidated Blue Beechcraft C17R “Staggerwing,” NC15835 (serial number C17R-81) from Detroit, Michigan, to Akron Municipal Airport, Akron, Ohio, in 40 minutes, 43 seconds. She had departed Detroit, Michigan, at 3:07:17 p.m., Eastern Standard Time (20:07:17 UTC) and crossed overhead Akron at 3:38:00. (20:38:00 UTC).

Mrs. Thaden Flies Akron-Detroit Route In 40 Minutes; Beats Ray Brown Record

Time Officially Clocked as Plane Hurtles Over Municipal Airport

By Helen Waterhouse

RUSHING through space in her streamlined blue plane yesterday afternoon, Mrs. Louise Thaden, plucky Bendix race winner, broke all previous records between Detroit and Akron.

     The tall Arkansas girl crossed Akron airport just 40 minutes and 43 seconds after leaving Detroit. That constituted an official record, Ray brown, official of the National Aeronautic association, said.

     “Wheels off and over the line, is the timing rule,” said Brown. “While Mrs Thaden did not actually land on the port until almost three minutes later, the time crossing the port is what counts.”

     The ship had accumulated such speed that it far overshot the port, and came roaring back from the east with the thunder of an army bomber.

BEATS BROWN BY TWO MINUTES

     “I beat you by two minutes, Ray,” called the smiling aviatrix as she leaned from the cockpit.

     She was referring to an unofficial record made by Brown last November. At that time Brown made the trip in 42 minutes, but there were no official checkers to record it.

     J.A. McCann and Airport Manager B.E. “Shorty” Fulton served in this capacity with Brown yesterday.

     The girl who has constantly made air records then climbed nimbly from the ship to be greeted by her hostess, Mrs. Brown, and a small crowd of spectators.

     Aside from the fact that her eyes were bloodshot from the wind, she showed no effects of the terrific speed at which she had traveled. “I hardly knew I had been in the air, it was such a short trip,” she laughed.

     Bareheaded when she landed, she jammed a gray sports hat onto her tousled hair as she alighted. She wore a gray flannel dress, gray sports shoes and a belted caracul coat.

BLAMES SELF FOR PASSING PORT

     Lighting one cigaret after another, she upbraided herself for having so far overshot the port.

     “Gosh, I don’t know what my top speed was,” she said. “I was too busy up there. I flew at 5,000 feet all the way.”

     She scanned the lowering clouds. A few drops of rain were falling. “Doubt if I get off for Montreal tomorrow,” she said cheerfully.

     She explained that from Montreal she is flying to the air show in New York City.

     Brown figured that the girl had averaged 160 miles and hour over the 110-mile route.

     “I just thought it would it would be fun to try to beat your record,” Mrs. Thaden said to him.

     After watching her speedy little ship into the Akron Airways hangar, she rode to town with the Browns.

     “Things are definitely picking up in the air industry,” she said. “In the last few months I have flown all over the country, and I see great evidence of the pickup in the industry all along the line.

[The distance between Detroit Metropolitan Airport (DTW) and Akron Fulton International Airport (AKR) is 127 statute miles (204 kilometers). Mrs. Thaden’s average speed over the course would have been 187.147 miles per hour (301.184 kilometers per hour).]

Just four months, 18 days earlier, Louise Thaden had become the first woman to win the Bendix Trophy Race, flying another Beechraft C17R “Staggerwing,” R15835, serial number C17R-77, from Floyd Bennett Field, Brooklyn, New York, to Mines Field, Los Angeles, California, in 14 hours, 55 minutes, 1.0 seconds.¹ [At this time, airplanes in the experimental or restricted categories were prohibited from displaying the U.S. national identifier, the letter N, as they were not allowed to fly outside the United States.]

The Bendix race winning airplane had already been sold to the government of the República de Honduras, but Walter Beech let Louse Thaden and Blanche Wilcox Noyes fly it for the race. It was then returned to the Beechcraft plant for overhaul and repainting, before being flown to Honduras by Paul E. Zimmerman. It was assigned to the Escuela Militar de Aviacion.

Beech had another Beechcraft C17R, serial number C17R-81, and also registered NC15835, built for Louise Thaden in October 1936, the month after the Bendix Trophy Race. After being test flown by Mrs. Thaden, it was delivered to her 12 October 1936. It was painted Consolidated Blue with white trim in the same paint scheme as C17R-77. The interior had blue leather seats with Colonial Blue carpet.

C17R-81 is the airplane that Thaden flew to set the 21 January 1937 record.

The Beechcraft C17R was single-engine, single-bay biplane operated by a single pilot and could carry up to three passengers in its enclosed cabin. The basic structure was a welded tubular steel frame with wood formers and stringers. The wings and tail surfaces were built of wood spars and ribs with the leading edges and wing tips covered with plywood. The airplane was covered with doped fabric, except the cabin and engine, which were covered in sheet metal. It was equipped with electrically-operated retractable landing gear and wing flaps.

The Beechcraft Staggerwing got its name because its lower wing was placed ahead of the upper wing (negative stagger). While most biplanes had staggered wings, the Staggerwing was unusual in having negative stagger. This not only increased the pilot’s field of vision, but improved the airplane’s stability in a stall. The Staggerwing was a fast airplane for its time and set several speed and altitude records.

The Beech C17R was 24 feet, 5 inches (7.442 meters) long with a wingspan of 32 feet, 0 inches (9.754 meters) and overall height of 8 feet, 2 inches (2.489 meters). According to the Bureau of Air Commerce license certificate dated 9 October 1936, C17R-81 had an empty weight of 2,393 pounds (1,085 kilograms), and its maximum gross weight was 3,900 pounds (1,769 kilograms).

The leading edge of the Model C17 upper wing was 2 feet, 1 inches (0.635 meters) aft of the lower wing. The leading edges had 0° sweep. Both wings had an angle of incidence of 3°. The upper wing had no dihedral, but the lower wing had +1°. The mean vertical gap between the wings was 5 feet (1.524 meters), and the chord of both wings was 5 feet, 0 inches (1.524 meters). The total wing area was 273 square feet (25.4 square meters). The horizontal stabilizer had 0° incidence, while the vertical fin was offset 0° 43′ to the left of the airplane’s centerline.

The Staggerwing was offered with a selection of engines of different displacements and horsepower ratings. The C17R was powered by an air-cooled, supercharged, 971.930-cubic-inch-displacement (15.927 liter) Wright Whirlwind 440 (R-975E3), a 9-cylinder direct-drive radial engine with a compression ratio of 6.3:1. The R-975E3 was rated at 420 horsepower at 2,200 r.p.m., and 440 horsepower at 2,250 r.p.m. for takeoff, burning 92-octane gasoline. The engine was 43.00 inches (1.092 meters) long and 45.25 inches (1.149 meters) in diameter. It weighed 700 pounds (318 kilograms). The serial number of the engine installed in C17R-81 was 12885. It drove a two-bladed adjustable pitch Hamilton Standard propeller with a diameter of 8 feet, 6 inches (2.591 meters), serial number 18560.

This engine gave the C17R Staggerwing a cruise speed of 195 miles per hour (314 kilometers per hour) at 5,000 feet (1,524 meters), 202 miles per hour (325 kilometers per hour) at 10,000 feet (3,048 meters) and maximum speed of 211 miles per hour (340 kilometers per hour). The service ceiling was 21,500 feet (6,553 meters) and its range with standard fuel capacity, 98 gallons (371 liters), was 800 miles (1,288 kilometers).

The rear passenger seats of C17R-81 were removed and a 56 gallon (212 liter) auxiliary fuel tank installed in their place, bringing to total fuel capacity to 121 gallons (458 liters).

Three C17R Staggerwings have been registered as N15835, including serial numbers C17R-74; C-17R-77, the Bendix race winner; and C17R-81, which was built for Thaden. FAA records indicate that the first, C17R-74, is currengtly registered N15835.

Mrs. Thaden’s personal C17R, s/n C17R-81, an incomplete restoration, was for sale at auction in November 2023.

4 September 1936: Louise Thaden was the first woman to win the Bendix Trophy Race when she and her co-pilot, Blanche Wilcox Noyes, flew a Beechcraft C17R “Staggerwing,” NR15835 (manufacturer’s serial number C17R-77), from Floyd Bennett Field, Brooklyn, New York, to Mines Field, Los Angeles, California, in 14 hours, 55 minutes, 1.0 seconds. With one fuel stop at the Beech Aircraft Company factory in Wichita, Kansas, Thaden and Noyes had averaged 165.35 miles per hour (266.11 kilometers per hour), even though—against the advice of Walter Beech—they had maintained only 65% power for the entire race. They landed at 4:49.49 p.m., Pacific Standard Time (00:49, 5 September, UTC).

In addition to the trophy, Mrs. Thaden won a prize of $4,500 for first place, plus $2,500 for the fastest speed in the race set by a woman (unaccompanied by a man).

She was also awarded the Harmon Trophy.

Laura Ingalls, flying her Lockheed Orion 9D Special, NR14222, finished in second place, arriving 45 minutes after Thaden and Noyes, at 5:54.28 p.m.. William Warner finished in third place in a Vultee V-1A, and George Pomeroy was fourth flying a Douglas DC-2 transport. And in fifth place was Amelia Earhart and Helen Richey in Earhart’s Lockheed Model 10E Electra Special, NR16020.

The Beechcraft C17R flown by Louise Thaden to win the Bendix Trophy, serial number C17R-77, had already been sold to the government of the Republic of Honduras, but Walter Beech let Thaden use it for the race before delivering to the owner. It was painted in Sherwin Williams Consolidated Blue with white stripes. The rear passenger seats were removed and a 56 gallon (212 liter) auxiliary fuel tank installed in their place.

After the race, the Staggerwing overhauled, repainted Insignia Blue with silver wings, and was flown to Central America by Paul E. Zimmerman. It was assigned to the  Escuela Militar de Aviacion.

Three C17R Staggerwings have been registered as N15835, including serial numbers C17R-74; C-17R-77, the Bendix race winner; and C17R-81, which was owned by Thaden. Current FAA records indicate that the first, C17R-74, is currently registered N15835.

Beechcraft produced thirteen of the C17R variant.

24 March 1939: During a 2 hour, 26 minute flight over southern California, Jacqueline Cochran established a U.S. National Altitude Record for Women of 9,160 meters (30,052 feet). She flew a Beechcraft D17W “Staggerwing,” serial number 164, registered NR18562.

A National Aeronautic Association official, Larry Therkelson, took the recording barograph from the airplane and sent it to the N.A.A. headquarters in Washington, D.C., for certification. The record had previously been held by Ruth Rowland Nichols.¹

“Were I to make the simple statement that I climbed to an altitude of thirty-three thousand feet, that statement in and of itself would mean nothing because I have often gone higher than that. But when I add that I did this in 1937 in a fabric-covered biplane without heating, without pressurization and without an oxygen mask, the elements of an accomplishment are added. I nearly froze; the pipestem between my teeth through which I tried to get an oxygen supply from a tank and connecting tube was inadequate for the purpose, and I became so disoriented through lack of oxygen that it took over an hour to get my bearings and make a landing. The difference between the pressure my body was accustomed to on the ground and the atmospheric pressure at 33,000 feet was such that a blood vessel in my sinus ruptured. All this was a part of the cumulative evidence that led up to cabin pressurization and and mandatory use of the oxygen mask above certain altitudes.”

The Stars at Noon, by Jacqueline Cochran, Little, Brown and Company, Boston, 1954, Chapter IV at Pages 61–62.

According to the U.S. Centennial of Flight Commission, Jackie Cochran “. . . set more speed and altitude records than any other pilot.”

The Beechcraft Staggerwing got its name because its lower wing was placed ahead of the upper wing (negative stagger). It was a fast airplane for its time and set several speed and altitude records. The Beechcraft D17W was a special version of the D17 production model. Only two were built. Jackie Cochran purchased it from Beech for $20,145, and it had been delivered to her by famed aviator Frank Hawks.

The “Staggerwing” was a single-engine, four-place biplane with an enclosed cabin and retractable landing gear, flown by a single pilot. The basic structure was a welded tubular steel framework, with wood formers and stringers. The wings and tail surfaces were built of wood spars and ribs. The airplane was covered with doped fabric, except the cabin and engine, which were covered in sheet metal.

The airplane was 26 feet, 10 inches (8.179 meters) long with a wingspan of 32 feet, 0 inches (9.754 meters) and overall height of 8 feet, 0 inches (2.438 meters). It had an empty weight of 2,540 pounds (1,152.1 kilograms) and loaded weight of 4,250 pounds (1,927.8 kilograms).

While most biplanes had staggered wings, the Staggerwing was unusual in having negative stagger. This not only increased the pilot’s field of vision, but improved the airplane’s stability in a stall. The leading edge of the Model 17 upper wing was 2 feet, 1–19/32 inches (0.65008 meters) aft of the lower wing. The leading edges had 0° 0′ sweep. Both wings had an angle of incidence of 5° 5′. The upper wing had no dihedral, but the lower wing had +1°. The mean vertical gap between the wings was 5 feet (1.52 meters), and the chord of both wings was 5 feet, 0 inches (1.524 meters). The total wing area was 269.5 square feet (25.04 square meters). The horizontal stabilizer had 0° incidence, while the vertical fin was offset 0° 43′ to the left of the airplane’s centerline.

The Staggerwing was offered with a selection of engines of different displacements and horsepower ratings. The standard Beechcraft D17S was equipped with an air-cooled, supercharged, 986.749-cubic-inch-displacement (16.170 liters) Pratt & Whitney Wasp Jr. A, a nine-cylinder radial engine producing 300 horsepower at 2,000 r.p.m at Sea Level. It had a maximum speed of 212 miles per hour (341 kilometers per hour), 670 mile (1,078 kilometer) range and service ceiling of 25,000 feet (7,620 meters).

The 1,343.804-cubic-inch-displacement (22.021 liter) Pratt & Whitney Wasp SC-G engine installed in Jackie Cochran’s D17W was an experimental version of the Wasp C with 5:4 propeller reduction gearing. It produced 600 horsepower at 2,850 r.p.m. for takeoff, and 525 horsepower at 2,700 r.p.m., up to 9,500 feet (2,896 meters). The SC-G never entered production.

Beechcraft D17W c/n 164, was impressed into military service at Tarrant Field, Texas, 12 March 1943. Assigned to the United States Army Air Corps, it was given the designation UC-43K Traveler and Air Corps serial number 42-107277. It was turned over to the Reconstruction Finance Corporation, 22 November 1944, for sale to the civil market. The airplane was now powered by a 971.930-cubic-inch displacement (15.927 liter) Wright R-975-5 Whirlwind nine-cylinder radial and was redesignated Beechcraft D17R. The Staggerwing was sold to the Carver Pump Company, Muscatine, Iowa, and registered NC50958.
