Gott mál. Langar bara að bæta við að það var Þjóðverjinn Otto Lillienthal sem var fyrirmynd bræðranna í þróun svifflugu sem þeir síðan bættu með mótor og stýriflötum. In the late 19th century experiments were being made with soaring machines and hang gliders, chiefly by Otto Lilienthal, who, with an arrangement formed on the plan of birds' wings, attempted to imitate their ‘soaring flight’. Following up Lilienthal's ideas, the Wright brothers produced their first powered aeroplane in 1903.
