Fail-safe design is the concept of integrating a high level of redundancy into aircraft structural design. A semi-monocoque design also has a safety risk involved if the skin is damaged, because it is still a load-bearing structure. The first recorded use of a monocoque shell, in the manufacture of a plane manufacture, was in 1912.
