The Fascinating Invention of the Past - the 1954 Drone-Copter Segway

The De Lackner HZ-1 Aerocycle was an interesting invention from the past, created for the American military as a personal helicopter that could be learned to control in just 20 minutes. It could reach speeds of up to 120 km/h and even land on water. However, its fuel capacity only allowed for a distance of 24 km. The project was closed due to impracticality and a dangerous design, as two accidents occurred during testing, one of which nearly cost the test pilot his life.
