They also said that pilots would often let them get a good look from the air as they were arriving to let them get a better understanding of the scene.
Haven't any of you played with trash bags over your head as kids? You definitely can get a few minutes out of a trash bag. It can also help you escape a building fire if you're only way out is through smoke. But this only works if you have an exact plan.
