FIRST EDITION. SIGNED BY EARHART. 20 Hrs. 40 Min. tells the story of Earhart's experiences as a passenger, along with Wilmer Lower Stultz and Louis Edward Gordon, aboard the three-engine monoplane Friendship which departed Newfoundland, Canada on 17 June 1928 and landed at Burry Port, Wales the following day. This flight made Earhart the first woman to cross the Atlantic by air; the following year she would recreate this journey on her own. Though Earhart did not fly she was given the official title of "aircraft commander." It was the first of two books Earhart would write during her lifetime. In 1937 she along with her co-pilot Fred Noonan would disappear somewhere in the Pacific Ocean while attempting to become the first female pilot to circumnavigate the globe.
