How do airline companies procure fuel for their fleet?
In the UK at least, the fuel comes through pipelines delivered directly at the airport.
But sending fuel via roads and rail made this precious and strategic commodity vulnerable to aerial attack.
The solution, hence, was to build a pipeline and hide it under the ground.
However, actual construction of the pipeline did not begin until after the war started.
Each person was responsible for a section of pipeline eight to ten miles long.
However, the military continues to use the system.
