Geraldine “Jerrie” Fredritz Mock (November 22, 1925 – September 30, 2014) was the first woman to fly solo around the world in 1964.
Mock flew a single engine Cessna 180 (registered N1538C) christened the “Spirit of Columbus” and nicknamed “Charlie.” The trip began March 19, 1964, in Columbus, Ohio, and ended April 17, 1964, in Columbus, Ohio, and took 29 days, 21 stopovers and almost 22,860 miles (36,790 km). She was subsequently awarded the Louis Blériot medal from the Fédération Aéronautique Internationale in 1965. In 1970 she published the story of her round-the-world flight in the book Three-Eight Charlie. While that book is now out of print, a 50th anniversary edition was later published including maps, weather charts and photos. Three-Eight Charlie is a reference to the call sign, N1538C, of the Cessna 180 Skywagon Mock used to fly around the world.
