The second try at flying by Vanden Plas was the "Médiaplan", subject of Belgian Patent 237.925 of 22 July 1911. It was built by the Laurent firm at Leuven, which built propellers and other aviation parts. It was shown at Ans on 15 June 1911, flown successfully by Westerlain, although it is reported it ran out of fuel and had to land in field. It was displayed at the XI Salon in Brussels in January 1912 and it was reported that flying would resume in Kiewit, but nothing was heard of it. It was powered by a Vivinus engine, later by a 50 hp Gnôme.
