This sextant was used in two of Charles A. Lindbergh's most important flights. On April 20, 1930 he and his wife set out from Glendale, California in a new Lockheed Sirius monoplane for a trans-Continental flight to test travelling at higher altitudes. They flew between 10,000 and 15,500 feet, and set a new trans-continental record to Roosevelt Field in 14hours, 45minutes and 33 seconds, besting Capt. Frank M. Hawks record by three hours. They made one stop and his wife, Elizabeth Morrow Lindbergh, acted as navigator and co-pilot using this sextant. The sextant was also used on his New York to China flight in 1931 as described in the following lot.
