jan 1, 1670 - Francesco Lana de Terzi
Description:
In 1670, Francesco Lana de Terzi published a work that suggested lighter than air flight would be possible by using copper foil spheres that, containing a vacuum, would be lighter than the displaced air to lift an airship. While theoretically sound, his design was not feasible: the pressure of the surrounding air would crush the spheres.Added to timeline:
