It builds on the platform of Franky Zapata's Flyboard Air, a green goblin-style flying platform with no Segway-style handgrips. The Flyboard Air, like the water-propelled Flyboard that started this whole venture for Zapata, straps you in at the boots, and requires an extraordinary amount of core strength and balance to operate – which its inventor most certainly has.

Zapata has frequently been seen zooming around over waterways in Europe and the United States, testing and updating his invention, sometimes with the blessing of the authorities, sometimes without.

The new Ezfly system is a dangerously disruptive idea, because it looks for all the world like it takes very little training to operate, so just about anyone could fly one. You don't strap your boots in, you just stand on the platform and hang onto the control sticks, pretty much like a three-dimensional Segway.
