I was inspired by this system, which allows someone to fly over water, to come up with today’s invention.
It’s a personal ‘jetpack’ the motors of which are supplied with electricity from a self-powered battery cart travelling on the ground. This could be remotely controlled to follow the pilot and avoid stressing the power cable.
The system allows flight only to a limited altitude but the time aloft could be as long as a whole day at a time. The cart might even be equipped with a large air bag in case the motors failed -so that the pilot could safely crash land.
