LZ 127 - Graf Zeppelin - General

Impressive footage of  the Graf Zeppelin, including a flight over the northeast Alps in Switzerland (Kürfirsten, Säntis), the Polar flight including mail drop to the Icebreaker Malygin, interviews mit Dr Eckener, landing in England with dropping of landing ropes from the front of the ship.

Historical notes, in Dutch, on the building of the Zeppelins, including Graf Zeppelin before her first America flight.

Round-the-Worl-Flight 1929
