Francis Stanley "Gabby" Gabreski (born Franciszek Gabryszewski; January 28, 1919 – January 31, 2002) was the top American fighter ace in Europe during World War II, a jet fighter ace in Korea, and a career officer in the United States Air Force with more than 26 years service, retiring with the rank of colonel. After his Air Force career, Gabreski headed the Long Island Rail Road, a commuter railroad owned by the State of New York, and struggled in his attempts to improve its service and financial condition. After two and a half years, he resigned under pressure and went into full retirement.
