Ferdinand von Zeppelin, who was born in Konstanz (Constance), originally had his airships built in a floating airship hangar on the lake which could be aligned with the wind to support the difficult launch procedure of rigid airship flight.[citation needed] Today there is a large Zeppelin Museum in Friedrichshafen sited near the lake shore. In recent years the company ZLT Zeppelin Luftschifftechnik GmbH, also located in Friedrichshafen, is the constructor of small, semi-rigid airships designed by the Zeppelin firm, named (called Zeppelin NT), by using modern technology.[citation needed] These airships can be booked for sightseeing tours above Lake Constance.
