Question: What American aviator famous and wealthy from flying exhibitions used the airfield Sagus Field?
Context: Gundaroo Airport (ICAO: YGDO) is a private airstrip located approximately 2 km south of the village of Gundaroo in the Southern Tablelands region of New South Wales, Australia.  The airport is on the grounds of "Bowylie Homestead", once the home of American actress Maud Jeffries and now the country estate of high-profile Australian aviator and entrepreneur Dick Smith.  The airfield is home to the Bowylie Flying Club, a museum collection of aviation memorabilia and amateur radio equipment.  The airside facilities are linked to the private homestead by a miniature railway which intersects the taxiway, requiring aircraft to give way to trains.  The airfield may be available to the public by prior arrangement and has been a destination for aero clubs.  The airfield has hosted a bi-annual rally for large scale model aircraft.  This event attracts participants from clubs across Australia. Penshurst Airfield was an airfield in operation between 1916–36 and 1940–46.  Initially a military airfield, after the First World War it was used as an alternate destination to Croydon Airport, with some civil flying taking place.  The airfield closed following the crash of a Flying Flea at an air display in 1936, and was converted to a polo ground. "The Aeroplanes at Brescia" (German: "Die Aeroplane in Brescia ") is a short story by Franz Kafka published, in slightly shortened form, in the newspaper "Bohemia" on 29 September 1909.  It describes an airshow in the Italian town Brescia, which Kafka saw with two of his friends (Max and his brother Otto Brod) during their journey to Italy.  Among other participants, they saw Louis Blériot, the aviator famous for the first flight across the English Channel.  The story is lively and witty, as Kafka was fascinated by the airshow.  It is also the first description of aeroplanes in German literature. Floyd Bennett Field was New York City's first municipal airport, later a naval air station, and is now a park.  While no longer used as an operational commercial, military or general aviation airfield, a section is still used as a helicopter base by the New York City Police Department (NYPD).  Located in Marine Park, southeast Brooklyn, the field was created by connecting Barren Island and a number of smaller marsh islands to the mainland by filling the channels between them with sand pumped from the bottom of Jamaica Bay.  The airport was named after famed aviator and Medal of Honor recipient Floyd Bennett, a Brooklyn resident at the time of his death.  It was dedicated on June 26, 1930, and officially opened on May 23, 1931.  The IATA airport code and FAA airfield identifier code was NOP when it was an operational naval air station and later coast guard air station, but now uses the FAA Location Identifier NY22 for the heliport operated there by the NYPD. Saugus Field also known as Atwood Park was an early American airfield located in Saugus, Massachusetts.  It was used by pioneer aviators Harry Atwood, Ruth Bancroft Law, and Lincoln J. Beachey. Joan Merriam Smith (c. 1937–1965) was an American aviator famous for her 1964 solo flight around the world that began and ended in Oakland, California, as she set out to follow the same route as the 1937 flight plan of Amelia Earhart.  Mrs. Smith had attempted to become the first woman to circumnavigate the globe by herself, but another woman, Jerrie Mock, set off during the same week and would complete the task earlier.  Already an accomplished pilot as Joan Merriam, she married Lt. Commander Marvin "Jack" Smith, Jr. in 1960. Lincoln J. Beachey (March 3, 1887 – March 14, 1915) was a pioneer American aviator and barnstormer.  He became famous and wealthy from flying exhibitions, staging aerial stunts, helping invent aerobatics, and setting aviation records. Stanisław Jakub Skarżyński (1 May 1899 − 26 June 1942) was a lieutenant colonel in the Polish Air Force and aviator famous for his transatlantic solo flight in 1933. The Daly Waters Airfield, also RAAF Base Daly Waters, is a former commercial and sporadically-used military airfield located at Daly Waters , Northern Territory, Australia.  As Australia's first international airfield, Daly Waters was used throughout the 1920s and 1930s as a stop over for commercial airlines operating on the domestic route to Western Australia and international carriers flying from Australia into south-east Asia.  During World War II, the airbase was used by the Royal Australian Air Force (RAAF) and the United States Army Air Force to undertake combat operations against the Japanese in New Guinea, the Dutch East Indies and the islands to Australia's north.  Following the war, the airbase was used commercially again up until the 1970s when the airfield was sporadically-used by the RAAF.
