HZ-1 Aerocycle, a Flying Segway From the 1950s

The 1950s were an interesting period in the helicopters history, when designers, encouraged by the military yearning for new combat capabilities, were trying to identify the most viable configurations and experimented a lot. This brought into existence a number of very peculiar rotorcraft. Among them was the HZ-1 Aerocycle, a compact aerial vehicle intended for carrying just one serviceman at a time.
