In the US, engineers have created a modern drone sketched by da Vinci

Leonardo da Vinci created a sketch of a drone that turned out to be working after 500 years – engineers were able to recreate it and win the competition.
Artist and inventor Leonardo da Vinci sketched a drone in the 1480s.
Surprisingly, a team of American engineers from Maryland took da Vinci’s sketches for a flight design contest and launched the device.
The drone has four corkscrew-shaped plastic wings – they powered by batteries and electric motors.
Like today’s drones, this creation based on small changes in rotational speed screws for tilting in one direction or another.
