The Imperial German Army Zeppelin LZ 80 (L-35) was a R-class World War I zeppelin.

Operational history

The airship took part in 13 reconnaissance missions around the North and Baltic Sea; three attacks on England dropping 4,284 kg (9,445 lb) of bombs. The designers tried to make LZ 80 (L-35) more efficient by removing one engine making the airship 1,750 kilograms (3,860 lb) lighter.[1]

Siemens torpedo glider testing

The last test flight of the Siemens torpedo glider was performed on August 2, 1918. On this flight a 1,000 kilograms (2,200 lb) biplane glider was launched from Zeppelin LZ 80 (L 35).[2][3] The glider was released from 1,500 metres (4,900 ft) over the Havel river and worked as expected until its control wire that attached the glider to the Zeppelin snapped and the glider spun out of control.[2]
