History

First successful experiments with hovercraft in the USSR date back to the mid-1930s and are tightly connected with the name of a talented engineer and designer Vladimir Levkov, who substantiated the possibility of hovercraft as far back as in 1925 in his treatise named The vortex theory of the rotor (Russian: Вихревая теория ротора). In 1934 the L-1 hovercraft boat which is sometimes referred to as the first hovercraft boat in the world was designed and built in his laboratory, with the L-5 fast-attack boat soon to follow. It became obvious that there was a great potential in further development of this technology of transportation.

BELOW: There are videos on Youtube of the actual skirt-less hovercraft in operation in the early 1930's - it was fast too.

So yes John, it's all been done before. And that's no joke.

Never think small, others aren't and they make things happen while the fools laugh.
