In the 15th-century Leonardo da Vinci created several flying machine designs incorporating aeronautical concepts, but they were unworkable due to the limitations of contemporary knowledge. [2] In the late 18th century, the Montgolfier brothers invented the hot-air balloon which soon led to manned flights.
Designs for flying machines by Leonardo da Vinci, c. 1490. Attempts to fly without any real aeronautical understanding have been made from the earliest times, typically by constructing wings and jumping from a tower with crippling or lethal results. [2] Wiser investigators sought to gain some rational understanding through the study of bird flight.
