Zeppelin flying over the valley
The zeppelin or airship is a self-propelled aerostat with the
ability to be manoeuver and be manipulated like an aircraft.
It was the first flying machine capable of being regulated
in a long duration flight. Its most important use occurred
between 1900 and the 1930s.
After several severe accidents,
its use decreased.
