Ellehammer's plane from 1906, with which on 12 September 1906 he made his first flight on a circular concrete runway, tethered to a pole in the middle. This has been claimed as a first powered flight in Europe, but it was not officially observed (Santos-Dumont Flight a few weeks later was observed and was officially recognized as the first powered flight in Europe). Reconstruction was made in the 1950s using several original parts (propeller, large drive wheel, support tubes for the engine, 3 cylinders and petrol tank).
