Trivia: What animal did Leonardo base his famous flying machine on?
Eagle
Sparrow
Bat
Bumblebee
Correct Answer: Bat
So why is this answer correct? : One of Leonardo’s most famous inventions was his flying machine, which he modeled after the physiology of a bat. Leonardo began his studies on the mechanics of flight in 1505. Many of his inventions and findings, including his flying machine, can be found in his book “Codex on the Flight of Birds.” Leonardo was ahead of his time — the first flight wouldn’t take place for another 400 years.
