Major August von Parseval’s Aeroboat of 1909 – “Das Aeroplan”, was taken to Plau, in Mecklenburg, where it was to be tested along the shore of the lake in 1910.

The first test of August von Parseval’s seaplane was on April 6, 1910 with pilot Oberingenieur Blochmann, but the plane would not leave the water. On April 14 the machine capsized in a storm and sank. The pilot was saved and the machine salvaged and modified. The biggest changes were straight wings (original wing tips were in V-shape), extra water planes and a triangular fuselage, instead of rectangular. Since the machine couldn’t start from water a Wright-like construction was built, with a trolley on rails. On October 7, 1910 a successful first attempt was made with the starting device. The machine flew at 3 meters for a length of 100-800 meters. A second flight on October 15, 1910 was very successful as the machine flew 3-4 kilometers. The landing on the water was not smooth, so Blochmann was lightly injured. Parseval realized that the machine could never start from the water and ended development.

The machine has a span of 14 metres, while it is 7 metres long and is fitted with a motor of 114-h.p.
