Hiller Flying Platform Concepts

In the 1940s and 50s, the dream of personal flying machines was popular. Charles Zimmerman proposed a flying platform with helicopter rotors at the bottom, allowing pilots to steer by shifting their weight. Various models emerged, but safety issues were a concern. The Hiller flying platform, a notable model, caught the US Army's attention for its potential to transport soldiers across battlefields. It featured a ducted fan and counter-rotating propellers, offering efficient lift and simple control by leaning in the desired direction.
