Royal Navy anxiety about aviation fuel grew from a First World War fire that destroyed a seaplane ship's aviation capability. After the war, the Navy examined captured German seaplane-carrier systems and other available examples before developing its own answer. The safety system then evolved through successive generations and rapid upgrades. Automatic drain-back removed fuel from idle lines, while gas purging reduced the danger left inside them. American observers initially saw the arrangements as obsessive, but combat experience made the useful elements increasingly attractive. The result came from institutional memory and repeated engineering changes over many years.

How Royal Navy aviation-fuel safety evolved
First World War fire experience, captured systems, and repeated refinement produced drain-back and gas-purging arrangements for aviation fuel.
