Harriet QuimbyBorn 11 May 1875; died 1 Jul 1912 at age 37.American aviator, the first female pilot to fly across the English Channel. Although she was the first American woman to become a licensed pilot, her career as a pilot lasted a mere 11 months. On 16 Apr 1912 she left England in a 50-hp monoplane lent to her by Louis Blériot. She headed for France in a plane she had never flown before and a compass she had just learned how to use. Despite poor visibility and fog, Quimby landed 59 minutes later near Hardelot, France. Upon landing, she was greeted by the local residents, but the Titanic sinking just days earlier, limited reporting of Quimby's achievement in the world press. She died the same year, on 1 Jul 1912, when she lost control of her plane at a flying exhibition near Quincy, Mass.[Birth day or year is uncertain; there is no birth certificate. 11 May 1975 is widely quoted, but Enc. Brit. gives born May 1, 1875?] |
