Скачать или смотреть Pentecost HX-1 Hoppi-Copter: The OG Flying Backpack That Predated Jetpacks

The Pentecost HX-1 Hoppi-Copter was one of the most daring aviation experiments of the 1940s. Designed by engineer Horace T. Pentecost, this one-man helicopter was intended to be worn like a backpack and powered by coaxial counter-rotating rotors. Originally developed for military mobility, the HX-1 later evolved into seated ultra-light helicopter variants. Despite successful flights, extreme control sensitivity and safety risks prevented mass production. Today, the Hoppi-Copter remains a legendary example of early personal aviation and experimental helicopter design.
