Well, when they saw the water wasn't doing nothing, you'd think it would have occurred to them to put foam on it.
My question is, they fought this fire for 4 hours in a major city, and the fire departments didn't put foam on it? Do they not have firefighting foam in Houston?
This was in Spring Texas, just north of Houston and the location would have been handled by your typical small suburbia type fire department.
Foam is water based.
