Loening OA-1A San Francisco

The historic Pan-American Goodwill Flight of 1926 and 1927 through Mexico and Central and South America was intended to improve relations with Latin American countries, to encourage commercial aviation, and to provide valuable training for Air Corps personnel. The flight was made by ten pilots in five Loening OA-1A amphibian aircraft. To stimulate public interest, each airplane was named after a major U.S. city-the New York, the San Antonio, the San Francisco, the Detroit, and the St. Louis.

The 22,000 mile flight began on December 21, 1926, from San Antonio, Texas. The journey took 59 flying days, interspersed with 74 days for scheduled maintenance and diplomatic meetings and ceremonies. The flight concluded at Bolling Field in Washington, D.C., on May 2, 1927. Within three weeks, however, the impressive achievement was eclipsed by Lindbergh's solo trans-Atlantic flight in the Spirit of St. Louis.

The San Francisco was transferred to the Smithsonian Institution by the War Department in December 1927. It was restored by the National Air and Space Museum in 1964-1965.
