How long does the first jet pack fly for?

The first successful jetpack flight, developed by Bell Aerosystems in the 1960s, lasted about 20 seconds. This early jetpack, known as the Bell Jetpack or Rocket Belt, allowed a pilot to ascend to a height of around 10 feet and travel a distance of approximately 100 feet. The limited flight duration was primarily due to the small fuel capacity. Subsequent designs have aimed to extend flight time, but early models were constrained by technology and safety considerations.
