Who were the first scientists to study air travel?
In the 13th century, Roger Bacon declared that he became certain air should support aircraft. At the start of the sixteenth century, Leonardo da Vinci studied the flight of birds and invented the propeller and the parachute. He made designs for three heavier-than-air craft, along with a helicopter with a rotor that helped it upward push vertically, and a glider with a wing constant to a frame. None of those became sensible at that time. But they were primarily based totally at the technology of flight.
