The headquarters of the “DELAG” were at Frankfort. It was from that city that the chief executives controlled operations. The Business Manager had charge of the financial and commercial activities. He supervised salaries, purchase of supplies, materials, etc. Flying operations were in charge of a Director of Flight. He had charge of the personnel at the air harbors; and all technical problems were put up to him. The crew of a commercial Zeppelin included the pilot, a reserve pilot, a flight mechanic, helmsmen and engineers, the number depending on the nature of the flight, a wireless operator and a ship’s steward. The crew usually aggregated twelve men. Created the First Airship Harbor As far as practicable, each Zeppelin was assigned to a definite air harbor, which was known as its home station, or terminal. Here all the repairs and maintenance were done. The members of the crew were assigned to suitable homes, all located in that immediate vicinity. The maintenance crews for airships and sheds were also stationed there. These auxiliaries averaged thirty persons under the direction of a foreman. They, too, formed the nucleus for the landing party necessary to handle the airships on arrival or departure. Each air harbor had a manager and his assistants to handle business details.

He was held strictly accountable for the safety of his ship; and acted as both station master and flying officer, subject only to instruction from the Director of Flight. The pilot alone made the decisions as to whether or not he should make a flight, when he should start and the number of passengers and crew he would carry. It is interesting to note that this system was adopted for the entire German airship force during the war. In fact, practically all airship personnel was trained by the “DELAG.” Like Land and Water Services There was no special organization for selling passenger accommodations. Agents of the Hamburg-American Line (“HAPAG”) which had offices in all German cities, also represented Zeppelin, and reservations were made on the same basis as for ocean going vessels. The “=Deutschland=” was the first Zeppelin operated by the “DELAG.” The motors, however, were not very dependable; and the low speed of the ship, combined with lack of experience made it susceptible to minor accidents. The =Deutschland= was so badly damaged, finally, that Zeppelin was compelled to rebuild her. During the period that she was being reconstructed the Zeppelin LZ-6 was substituted.
