17991883, Dec 13
born in Sheffield, England and is known for his work on the Aerial Steam Carriage with William Samuel Henson. In 1848 Stringfellow achieved the first powered flight using an unmanned 10 ft wingspan steam-powered monoplane built in a disused lace factory in Chard, Somerset. Employing two contra-rotating propellers on the first attempt, made indoors, the machine flew ten feet before becoming destabilised, damaging the craft. The second attempt was more successful, the machine leaving a guide wire to fly freely, achieving some thirty yards of straight and level powered flight.
