this history of foaming runways is an interesting one. as I said, in the USA no foam for over twenty years at civil airport...none at military airports for over 15.
HIGH protein foam was used and it did help a tiny bit...time constraints demanded foaming within 15 minutes of landing. foams were made from animal byproducts, hence the term "BLOOD AND GUTS" foam. very hard to clean up. Very specialized gadgets to make the foam.
Current foam is more like soap and is used after a landing/crash.
in the old days, gasoline was a bit more likely to explode than jet a...at military fields planes with nuclear bombs were given every advantage ;-)
I would have to feel that I would want to shut down the engines prior to touchdown and try to get props to stop by selecting feather...having them break apart on touchdown might be bad...of course the "book" has to be followed and once shutdown, YOU ARE LANDING...no go around.
bravo to aany crew with a good landing!
