The AirFish is a smaller version of this. The cupped shape of its wings does not appear to have curves, which means it will crease like oragami (welded sheet metal sections?) Since the in-ground effect is limited to a couple dozen feet - this craft is compatible only with the calm waters of a bay/lake/river. Maybe shorelines, but large breaking swells would be rough for the small, personal vessel anyways. That is why it's safe - unleaded gasoline spinning a prop with similar horsepower of a V8 barely suspended above the low friction and cushion of flat water. An error (equipment or operator) would occur at low altitude and the optimum resolution would be to skid-to-a-float (last resort safety measure is to guarantee the nose is up at sufficient angle because the marine body is both landing gear and airbag in a sense). Could the wing sections fold along the creases and temporarily adopt a more aero dynamic configuration in order to "leap" across impediments to a smooth surface? Flat land could also be a surface off of which a fuselage could propel itself via in-ground effect wingspan geometry, in which case "roads" would only need to be relatively flat and straight "lanes" with wingspan accommodation. Impact buffer would be suspension and durable tires (along with similar software interventions - "if impact imminent then nose up to skid instead of tumble") instead of sufficiently deep water and a marine body.
