How do firefight aircraft drop water? I've heard that it's like an agricultural sprayer, but also that it's just dropped as a mass and lands like a bomb on the ground. My firefighting background comes from the Navy and I learned that water puts a fire out by cooling it below the ignition point and to a lesser point, by smothering it. A stream of water is not as effective as a spray. Because of that, I'd expect a sprayer to be effective but a a "drop" to be largely ineffective. Please avoid the obvious political extension, I'm just trying to figure out how aircraft drop water.
