Of course, in WW2, as I'm sure you know, with your experience,
airfields were cleared of for by burning diesel on either side of the
runways. It wass horrendously expensive. Tens of thousands of gallons
were burned on a single airfield in one night, but it kept many
returning pilots, low on fuel at the end of a raid, alive.

That was FIDO and it was still installed (though I never saw it used)
at RAF Marham when I was stationed there in the late 50s / early 60s.

(Marham was aka El Adem with grass)
