The fire started in a motor home. The wood paneling and L.P. gas inside finally blew out of the home when the windows went. The fiberglass outer shell kept the sprinklers from reaching the fire. Once it was outside the vehicle it went clear to the roof, above the sprinklers.
WestUP.S. My oldest brother had just been put in charge of construction / buildings for K-mart (East coast) when they lost that warehouse. He said that the steel sprinkler pipes were melting while still discharging water.
