The Flyer was to be the hooligan sports car of the eVTOL world, a single-seater manned multirotor with pontoon floats for aquatic vertical takeoff and landing. It looked schmick, it flew for up to 20 minutes on a charge, and it'd do around 20 mph (32 km/h), swooping and banking over the water up to a limited altitude of around 10 ft (3 m).

Certainly, the airframe could take a person much higher or fly over land, but if you can't work out why that's a bad idea at this early stage, perhaps this video will clarify things.

Best of all, it was incredibly easy to fly, no harder than a DJI Phantom drone. GPS-stabilized and aided by banks of inertial sensors, it required no more than a couple of hours of training to get you in the air. As a Part 103 ultra-lightweight under FAA regulations, you didn't need a license to fly it provided you stayed away from certain areas. Kitty Hawk once trained 50 people to fly it in a single day.
