Recently in Samara one could notice people flying over the Volga river - one of the widest rivers of Europe - with some strange equipment. The equipment turned out to be called "flyboard" and was brought from France for 15 thousand dollars. Approximately the same sum was required to make it work in full force. The guys who had a chance to use it say that the most important thing is not to fall on a Sea Doo following behind. One can fly 14 m high with the thing (height of a 5 storey builidng). It's not too speedy but gives a chance fly over the Volga without touching the water.
