Although a replacement for LZ 4, the LZ 5 was built and accepted into Army service as L II, Zeppelin's relationship with the military authorities continued to be poor, and deteriorated considerably due to his criticism of the Army following the loss of L II, which was carried away from its moorings and wrecked on 25 April 1910. However, the business director of Luftschiffbau-Zeppelin, Alfred Colsman, came up with a scheme to capitalise on the public enthusiasm for Zeppelin's airships by establishing a passenger-carrying business.
