Abstract: Fire that has started in an enclosed space in an aircraft is smothered by closing or at least partly closing any air flow inlet and any air flow outlet of the enclosed space in response to a temperature rise caused by a fire in the enclosed space such as a toilet or crew quarters, galley cabinets, or the like.

Preferably a guide surface guides the expanding intumescent material into the apertures or openings at least when the expansion starts.

Abstract: A rocket propelled textile and cordage net fire extinguishing system is deployed from a platform at a safe standoff distance from a fire. The rocket propelled matrix-like net flies over, lands on, and drapes over the burning site.
