Who designed the flying machine used by Ezio in Assassin's Creed Brotherhood?

Leonardo da Vinci designed the flying machine used by Ezio in Assassin's Creed Brotherhood.

In the game's Renaissance-era story, Leonardo is Ezio's ally and inventor. He creates a glider inspired by his studies of flight, allowing Ezio to launch an aerial assault during a mission in the Romagna countryside. The sequence is fictionalized, but it draws on Leonardo's real notebooks and his fascination with wings, air currents, and mechanical flight.

The machine should not be confused with a modern airplane or with Leonardo's other inventions in the series. Brotherhood uses the historical artist and engineer as a character who helps Ezio with weapons, equipment, and technical solutions. Leonardo also appeared prominently in Assassin's Creed II, where his inventions support Ezio's earlier adventures.
