1 gen 1848 anni - First Powered Flight
Descrizione:
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. ~Wikipedia
