19 March–17 April 1964: Geraldine Fredritz (“Jerrie”) Mock landed her 1953 Cessna 180, Spirit of Columbus, N1538C, at Columbus, Ohio, completing a circumnavigation of the Earth she had begun at 9:31 a.m., 19 March 1964. Mock was the first woman to complete a circumnavigation by air. Her journey covered 23,103 miles (36,964 kilometers). The total elapsed time was 29 days, 11 hours, 59 minutes. The flight set a Fédération Aéronautique Internationale (FAI) World Record for Speed Around the World, Eastbound, of 52.75 kilometers per hour (32.78 miles per hour).¹

Jerrie Mock held twenty-two FAI world records, set between 1964 and 1969.

Cessna 180 serial number 30238 was built by the Cessna Aircraft Company, Inc., Wichita, Kansas, in 1953, and registered N1538C, the first year of production for the model. It was the 238th of 640 Model 180s that were built during the first year of production. 6,193 were built by the time production came to an end in 1986. N1538C was purchased for Jerrie Mock in 1963, with a total of 990 hours on the engine and airframe. The passenger seats were removed and replaced with additional fuel tanks. Additional radios and instruments were installed.

The Cessna Model 180 is an all-metal, four-place, single-engine, high-wing monoplane with fixed landing gear. It is 25 feet, 6 inches (7.772 meters) long with a wingspan of 36 feet, 2 inches (11.024 meters) and height of 7 feet, 6 inches (2.286 meters). If the optional rotating beacon is installed, the height is increased to 7 feet, 9 inches (2.362 meters). The Cessna 180 has an approximate empty weight of 1,525 pounds (692 kilograms), depending on installed equipment, and the maximum gross weight is 2,800 pounds (1,270 kilograms).

Spirit of Columbus is powered by an air-cooled, normally-aspirated 471.239-cubic-inch-displacement (7.722 liter) Continental O-470-A horizontally-opposed six-cylinder overhead valve (OHV) direct-drive engine with a compression ratio of 7:1. This engine is rated at 225 horsepower at 2,600 r.p.m., burning 80/87 aviation gasoline, and turns a two-bladed constant speed propellerwith a diameter of 6 feet, 10 inches (2.083 meters).

The airplane has a cruise speed of 162 miles per hour (261 kilometers per hour) at 6,500 feet (1,981 meters), and its maximum speed is 170 miles per hour (274 kilometers per hour) at Sea Level. Its service ceiling is 19,600 feet (5,974 meters). The Cessna 180 has a maximum fuel capacity of 84 gallons (318 liters), giving it an optimum range of 1,215 miles (1,955 kilometers) at 10,000 feet (3,048 meters) and 121 miles per hour (195 kilometers per hour).

After her around the world flight, Jerrie Mock never flew Spirit of Columbus again. Cessna exchanged it for a new six-place P206 Super Skylane, N155JM. For many years N1538C was hanging over a production line at the Cessna factory. Today, Mock’s Cessna 180 is on display at the Steven F. Udvar-Hazy Center, Smithsonian Institution National Air and Space Museum.

On 4 May 1964, President Lyndon B. Johnson presented Jerrie Mock with the Federal Aviation Agency Gold Medal for Distinguished Service, and the Fédération Aéronautique Internationale awarded her its Louis Blériot Silver Medal.

Jerrie Fredritz graduated from Newark High School in 1943, then studied aeronautical engineering at Ohio State University, Columbus, Ohio. She was a member of the Phi Mu (ΦΜ) sorority.

Miss Fredritz married Russell Charles Mock, 21 March 1945, in Cook County, Illinois. They would have three children, Valerie, Roger and Gary.

Jerrie Mock wrote about her around-the-world flight in Three Eight Charlie, published by Lippincott, Philadelphia, Pennsylvania, 1970.

Geraldine Fredritz Mock died at Qunicy, Florida, Monday, 30 September 2014, at the age of 88 years. She had requested that her ashes be spread over the Gulf of Mexico.

10 April 1972: Lieutenant-Colonel W. Roy Windover, Royal Canadian Air Force, a pilot assigned to the North American Air Defense Command (NORAD), set a Fédération Aéronautique Internationale (FAI) World Record for Altitude when he flew a 1941 Interstate Cadet S-1A, N37239, to an altitude of 9,388 meters (30,801 feet) ¹ over Pikes Peak, a 14,115 foot (4,320 meter) mountain in the Front Range of the Rocky Mountains, near Colorado Springs, Colorado.

For this achievement, the FAI awarded him its Médaille Louis Blériot.

Lieutenant-Colonel Windover had previously set a Canadian national record by flying a Cessna 140 to 27,050 feet (8,245 meters).

William Roy Windover was born 26 November 1924 at Belleville, Ontario, Canada. He was the son of William Everette Windover and Ella May Charlton Windover.

Pikes Peak, 14,115.19 feet (4,302.31 meters), west of Colorado Springs, Colorado.

Roy Windover learned to fly in 1941. He joined the Royal Canadian Air Force in 1943. He was “seconded” to the Royal Navy and Royal Canadian Navy.

Windover married Genevia Topelko, 10 Feb 1945. They would have three children, Jo-Anne, Roy and Rodderick. They later divorced. Mrs. Windover died in 2005.

In 1958, Flight Lieutenant Windover had been the first Royal Canadian Air Force Red Knight, a solo aerobatics demonstration performer, flying a bright red Canadair CT-133 Silver Star.

In 1974–1974, Windover served at National Defense Headquarters, Ottawa.

On 26 April 1983, Lieutenant-Colonel Windover married Cecile Rose Bruyere.

Lieutenant-Colonel William Roy Windover, Royal Canadian Air Force, Retired, died in an automobile accident, 29 May 1990 at the age of 65 years. He was buried at the Beechwood National Cemetery, Carleton, Ontario.

Windover’s Interstate Cadet S-1A, serial number 82, was built by the Interstate Aircraft and Engineering Company, El Segundo, California, in 1941. The airplane was assigned an Airworthiness Certificate on 18 December 1958 and registered N37239.

The Cadet was a single-engine, high-wing monoplane with a tandem cockpit and fixed landing gear. The fuselage of the Cadet was built of a tubular steel framework. The wings had two spruce spars with Alclad metal ribs. The leading edges were covered in Dural sheet and the complete wing then covered in doped fabric. The wing support struts were made of tubular steel. The S-1A was 24 feet, 0 inches (7.315 meters) long with a wingspan of 35 feet, 6 inches (10.820 meters) and height of 7 feet, 3 inches (2.210 meters). The airplane had an empty weight of 720 pounds (327 kilograms) and maximum weight of 1,200 pounds (544 kilograms).

The Interstate Cadet S-1A was powered by an air-cooled, normally-aspirated 171.002-cubic-inch-displacement (2.802 liter) Continental A65-8 horizontally-opposed four cylinder direct-drive engine, with a compression ratio of 6.3:1. It was rated at 65 horsepower at 2,300 r.p.m. at Sea Level, using 73-octane gasoline. The engine turned a two-bladed fixed-pitch wooden propeller with a diameter of 6 feet, 4 inches (1.930 meters).

At the time N37239 set this record, it was powered by an air-cooled, normally-aspirated, 171.002-cubic-inch-displacement (2.802 liter) Continental A75 horizontally-opposed four-cylinder engine with a compression ratio of 6.3:1, rated at 75 horsepower at 2,600–2,650 r.p.m. (depending on variant) at Sea Level. The A75 also required a minimum grade73-octane aviation gasoline.

The Cadet S-1A had a maximum speed of 103 miles per hour (166 kilometers per hour) in level flight, and 139 miles per hour (224 kilometers per hour) in a dive. The service ceiling was 14,500 feet (4,420 meters). The S-1A’s fuel capacity was 15 gallons (57 liters). Its maximum range was approximately 350 miles (563 kilometers).

Approximately 320 Cadets were built by Interstate during 1941–1942. In 1942 and 1943, another 259 were built as OX-63, L-6 and L-8 Grasshopper light observation airplanes.

N37239 caught fire during a training flight near Amarillo, Texas, 12 January 1995. After an emergency landing, the airplane was destroyed by the fire. The cause was not determined. The airplane was rebuilt and issued an Airworthiness Certificate 8 April 1999. It is currently registered in Farmington, Missouri.²
