jan 1, 1799 - Sir George Cayley
Description:
The modern airplane has its origin in a design set forth by George Cayley in 1799. It was the first concept to include a fixed wing for generating lift, another separate mechanism for propulsion (Cayley envisioned paddles), and a combined horizontal and vertical (cruciform) tail for stability. Cayley inscribed his idea on a silver disk (presumably for permanence). On the reverse side of the disk is a diagram of the lift and drag forces on an inclined plane (the wing).Added to timeline:
