Leonardo da vinci came up with the idea of a flying machine using a sail-screw.
It took hundreds of years of developments in metalwork, engines, fuels before they could begin to work on the airfoil components.
In the 1940's, the culmination of all these areas of study finally created the conditions necessary to be able to build a helicopter that could safely move through the air.
