"We must be on you, but cannot see you -- but gas is running low. Have been unable to reach you by radio. We are flying at 1,000 feet." Amelia Earhart's last radio transmissions left few clues to her 1937 disappearance over the Pacific, but the legend of this pioneer female aviator was already firmly in place. Mary S. Lovell's adeptly crafted biography of this short-haired, Kansas-born feminist pays due tribute to Earhart's spunk and daring; it also shows that she was no tragic pawn of her publicist husband, George Putnam.
