The Winnie Mae is a modified Lockheed 5C Vega flown by Wiley Post during the 1930 National Air Races, winning first place with a time of 9 hours, 9 minutes, and 4 seconds, as well as setting records for the fastest around-the-world flight in 1931, with a time of 8 days, 15 hours, and 51 minutes, the first solo around-the-world flight in 1933, [1] and the flight altitude record in 1934, reaching 50,000 feet. [2] The Winnie Mae was sold to the Smithsonian Institution after Wiley Post's death, where it is currently being displayed at the National Air and Space Museum in Washington D.C.
The Winnie Mae was built in 1930 by the Lockheed Corporation in Burbank, California, with the serial number 122 as a Lockheed 5B model. [3] In June of 1930, Florence C. Hall, an oil baron based in Chickasha, Oklahoma, purchased the Winnie Mae for $22,000 and named it after his daughter. The plane had been intended for personal use and Hall's personal pilot, Wiley Post, would pilot the aircraft. [4] On August 27th, 1930, with permission from the plane's owner Florence C. Hall, Wiley Post entered the Winnie Mae in the National Air Races. Winning first place in the men's non-stop cross-country derby securing a cash prize of $7,500 and setting a record time of 9 hours, 9 minutes, and 4 seconds; an achievement which was painted on the plane's fuselage. [5] [6]
On June 23rd, 1931, Wiley Post along with Australian aviator Harold Gatty acting as navigator departed New York in an attempt to beat the record for the fastest around-the-world flight. After 14 refueling stops they landed back in New York on July 1st, 1931, having completed the circuit in 8 days, 15 hours, and 51 minutes. Being the first to complete an around-the-world flight in a fixed-wing aircraft and beating Hugo Eckener's previous record of 21 days, 5 hours, and 31 minutes in a Zeppelin. After completing the flight, Wiley Post acquired Winnie Mae from Florence C. Hall. [1] On July 8th, 1931, Wiley Post competed in the National Air Races again with the Winnie Mae, being beaten by Jimmy Dolittle in a Laird Super Solution.
In 1932, Wiley Post converted the Winne Mae from a Lockheed 5B to a Lockheed 5C model and installed various other modifications. Its Wasp C engine was upgraded with cylinders from a Wasp C1, increasing the horsepower from 420 to 500. Its fixed-pitch propeller was upgraded to a Smith 450-SI variable-pitch propeller, and the wing's angle of incidence was decreased by 10 degrees to increase the plane's airspeed by approximately 10 MPH (16 KPH). In 1933, Wiley Post installed a Sperry gyroscopic autopilot, a fairly new invention at the time, and added six auxiliary fuel tanks in preparation for his solo around-the-world flight, giving the Winnie Mae a fuel capacity of 645 gallons. [3]
On July 15th, 1933, Wiley Post departed Floyd Bennett Airfield, New York, in the Winnie Mae on what would become the first solo around-the-world flight. [1] At 11:58 A.M. (AKST) on July 20th, 1933, after a 3,000-mile leg from Khabarovsk, Siberia to Nome, Alaska, Post overflew his destination and got lost, crash-landing next to a U.S. Army Signal Corps radio station at Flat, Alaska after 7 hours of searching for an airfield. The aircraft's wheels sank into the soft ground causing the plane to nose over, damaging its propeller, engine cowling, and right landing gear strut. Replacement parts were flown in from Fairbanks, Alaska, and after repairs, the Winnie Mae departed Alaska the following day at 7:28 A.M. (AKST). Post completed his record-breaking solo around-the-world flight in 7 days, 18 hours, and 49 minutes, stopping 11 times for fuel. [3] When the Winnie Mae landed back in New York on July 22nd, over 50,000 spectators gathered to catch a glimpse of Wiley Post and his now-famous aircraft. [7]
In early 1934, Wiley Post started modifying the Winnie May for high-altitude long-distance flights, supercharging the engine and adding jettisonable landing gear as well as a skid to land on, this design was chosen to reduce drag on the aircraft. The Winnie Mae could not be pressurized due to its wooden construction, so Post had a full-body pressure suit made with financial support from the Phillips Petroleum Company. [1] On December 7th, 1934, Post flew the Winnie Mae to an estimated fifty thousand feet above Bartlesville, Oklahoma, unofficially setting the flight altitude record for a fixed-wing aircraft. [4] Wiley Post understood that planes fly faster at higher altitudes, so he set out to beat the current cross-country speed record. [2] After four failed attempts, Post settled for the Burbank, California, to Cleveland, Ohio, route, which he completed on March 15, 1935, covering the 2,035 miles in the stratosphere in 7 hours, 19 minutes at an impressive 340 MPH (547 KPH). [5] For comparison, the Lockheed 5C Vega normally had a top speed of 185 MPH (298 KPH). [1] The Winnie Mae was able to achieve its high speeds by flying in the jet stream, a fast-flowing atmospheric air current.
Wiley Post died in a plane crash on August 15, 1935, while flying a modified Lockheed Orion near Point Barrow, Alaska. Shortly after in 1936, Post's wife sold the Winnie Mae for $25,000 to the Smithsonian Institution, which still preserves it at the National Air and Space Museum in Washington, D.C. [8]

General characteristics
Performance
The Lockheed Vega is an American five- to seven-seat high-wing monoplane airliner built by the Lockheed Corporation starting in 1927. It became famous for its use by a number of record-breaking pilots who were attracted to its high speed and long range. Amelia Earhart became the first woman to fly solo across the Atlantic Ocean in one, and Wiley Post used his to prove the existence of the jet stream after flying around the world twice.
The Lockheed Model 9 Orion is a single-engined passenger aircraft built in 1931 for commercial airlines. It was faster than any American military aircraft of that time. Designed by Richard A. von Hake, it was the last wood aircraft produced by the Lockheed Aircraft Corporation.
The Rutan Model 76 Voyager was the first aircraft to fly around the world without stopping or refueling. It was piloted by Dick Rutan and Jeana Yeager. The flight took off from Edwards Air Force Base's 15,000 foot runway in the Mojave Desert on December 14, 1986, and ended 9 days, 3 minutes and 44 seconds later on December 23, setting a flight endurance record. The aircraft flew westbound 26,366 statute miles at an average altitude of 11,000 feet (3,350 m).
The Boeing 377 Stratocruiser was a large long-range airliner developed from the C-97 Stratofreighter military transport, itself a derivative of the B-29 Superfortress. The Stratocruiser's first flight was on July 8, 1947. Its design was advanced for its day; its relatively innovative features included two passenger decks and a pressurized cabin. It could carry up to 100 passengers on the main deck plus 14 in the lower deck lounge; typical seating was for 63 or 84 passengers or 28 berthed and five seated passengers.
The Douglas C-133 Cargomaster is an American large turboprop cargo aircraft built between 1956 and 1961 by the Douglas Aircraft Company for use with the United States Air Force. The C-133 was the USAF's only production turboprop-powered strategic airlifter, entering service shortly after the Lockheed C-130 Hercules, which is designated a tactical airlifter. It provided airlift services in a wide range of applications, being replaced by the C-5 Galaxy in the early 1970s.
The Douglas DC-7 is an American transport aircraft built by the Douglas Aircraft Company from 1953 to 1958. A derivative of the DC-6, it was the last major piston engine-powered transport made by Douglas, being developed shortly after the earliest jet airliner—the de Havilland Comet—entered service and only a few years before the jet-powered Douglas DC-8 first flew in 1958. Larger numbers of both DC-7B and DC-7C variants were also built.
Wiley Hardeman Post was an American aviator during the interwar period and the first pilot to fly solo around the world. Known for his work in high-altitude flying, Post helped develop one of the first pressure suits and discovered the jet stream. On August 15, 1935, Post and American humorist Will Rogers were killed when Post's aircraft crashed on takeoff from a lagoon near Point Barrow in the Territory of Alaska.
This is a list of aviation-related events from 1931:
The Republic XF-12 Rainbow was an American four-engine, all-metal prototype reconnaissance aircraft designed by the Republic Aviation Company in the late 1940s. Like most large aircraft of the era, it used radial engines, specifically the Pratt & Whitney R-4360 Wasp Major. The XF-12 was referred to as "flying on all fours" meaning: four engines, 400 mph (640 km/h) cruise, 4,000 mi (6,400 km) range, at 40,000 ft (12,000 m). The aircraft was designed to maximize aerodynamic efficiency. Although innovative, the jet engine and the end of World War 2 made it obsolete, and it did not enter production. A proposed airliner variant, the RC-2, was deemed uneconomical and cancelled before being built.
Solar Impulse is a Swiss long-range experimental solar-powered aircraft project, and also the name of the project's two operational aircraft. The privately financed project is led by Swiss engineer and businessman André Borschberg and Swiss psychiatrist and balloonist Bertrand Piccard, who co-piloted Breitling Orbiter 3, the first balloon to circle the world non-stop. The Solar Impulse project's goals were to make the first circumnavigation of the Earth by a piloted fixed-wing aircraft using only solar power and to bring attention to clean technologies.
The Lockheed Explorer was the least successful wooden airplane design produced by the Lockheed Aircraft Company. The Vega fuselage was combined with a cantilevered low wing. Seating for a single pilot was provided in an open cockpit behind the wings.
Allan Haines Lockheed was an American aviation engineer and businessman. He formed the Alco Hydro-Aeroplane Company along with his brother, Malcolm Loughead, which became Lockheed Corporation.
VL Pyry was a Finnish low-winged, two-seated fighter trainer aircraft, built by the State Aircraft Factory for use with the Finnish Air Force. The Pyry was in use from 1939 to 1962. The aircraft was a mixed construction of wood, steel, fabric, and duraluminium.
Harold Charles Gatty was an Australian navigator and aviation pioneer. Charles Lindbergh called Gatty the "Prince of Navigators." In 1931, Gatty served as navigator, along with pilot Wiley Post, on the flight which set the record for aerial circumnavigation of the world, flying a distance of 15,747 miles (24,903 km) in a Lockheed Vega named the Winnie Mae, in 8 days, 15 hours and 51 minutes.
The Lockheed XC-35 is a twin-engine, experimental pressurized airplane. It was the second American aircraft to feature cabin pressurization. It was initially described as a "supercharged cabins" by the Army. The XC-35 was a development of the Lockheed Model 10 Electra that was designed to meet a 1935 request by the United States Army Air Corps for an aircraft with a pressurized cabin.
The Junkers Ju 49 was a German aircraft designed to investigate high-altitude flight and the techniques of cabin pressurization. It was the world's second working pressurized aircraft, following the Engineering Division USD-9A which first flew in the United States in 1921. By 1935, it was flying regularly to around 12,500 m (41,000 ft).
The Lockheed C-69 Constellation is a four-engined, propeller-driven military transport aircraft developed during World War II. It was co-developed with the Lockheed Constellation airliner.
The gyroscopic autopilot was a type of autopilot system developed primarily for aviation uses in the early 20th century. Since then, the principles of this autopilot has been the basis of many different aircraft control systems, both military and civilian.
The Curtiss/Curtiss-Robertson Model 56 Thrush was a 1929 six passenger high-wing fixed undercarriage single-engine cabin monoplane airliner and utility transport powered by either a Curtiss Challenger or a Wright Whirlwind radial engine and built as an enlargement of the earlier Curtiss Robin. Several were used for record breaking endurance flights by female pilots during the early 1930s including one in which the aircraft stayed aloft for almost ten days.
The Vega Model 2 Starliner was a prototype five-seat feeder airliner produced by the Vega Airplane Company, a subsidiary of Lockheed. It was designed to be powered by an unusual powerplant, consisting of two Menasco piston engines coupled together to drive a single propeller. A single example was built, flying in 1939, but no production followed.
