That book probably covers the operation to get fuel across the Channel for the D Day invasions. I'm fairly sure Brenzett Aeronautical Museum had a section about it along with some pipe and equipment when I went a few years ago.

There were so many astonishing developments in the background to support the front end fighting which are so easily overlooked.

Thanks for the book info, I've flagged that to get at some point.
