jetpacks

A jetpack is a wearable device that allows a person to fly or lift off the ground using thrust generated by jets or rocket engines. Typically, jetpacks use compressed air, gas, or liquid fuel to produce powerful streams of hot gases expelled through nozzles, creating the force needed to lift or propel. They are often strapped to the back with controls for steering and throttle. While historically experimental, modern designs are being used for entertainment, rescue missions, or specialized industrial tasks, offering portable mobility through controlled, vertical flight.
