It was 1970 when Modern Hover Vehicles brought forth their Spectra-1.
The tandem seating, now common place, seemed revolutionary. It was
unfortunately marketed as a replacement to the snowmobile - which it wasn't! Twin vertically mounted axial fans were powered by a Kohler 18.5 hp 2-stroke

connected to a 2-bladed propeller.
