Abstract:

Two nonrigid airship envelopes were removed from storage and the envelopes were inspected to determine their suitability for further flight service. The ZPG-3W envelope was found to be extensively damaged due to conditions under which it was stored. It was judged irrepairable and was scrapped. The ZPG-2 envelope was in good condition generally. The envelope was considered to be suitable for further flight service when reinforcement of the upper surface was accomplished.
