How Ben-my-Chree shaped British carrier fuel safety

What was Ben-my-Chree, and why did it make the Royal Navy so cautious about aviation fuel?

It was a converted ferry used as a First World War seaplane tender, and its aviation fire helped inspire exceptionally cautious British fuel-storage and drainage systems.

Ben-my-Chree was a converted ferry used by the Royal Navy as a seaplane tender, and her destructive aviation fire became a lasting institutional warning. British carriers consequently used deeply protected tanks, isolation measures, and fuel lines designed to drain rapidly after use. American observers initially regarded the arrangements as over-engineered, but combat losses made the safety logic more persuasive. British carrier survivability depended on subdivision and fuel handling as well as armour.
