Fighting wildfires is sometimes a daunting prospect with manned aircraft; pilots can't always fly around the clock or cover every patch of land. They won't have to if Lockheed Martin's efforts pan out. It recently demonstrated a tweaked version of its unmanned K-MAX helicopter that can work in tandem with a quadrotor drone, Indago, to stamp out fires with relatively little human intervention. As you'll see in the clip below, Indago serves as a forward scout that marks any hotspots. After that, K-MAX swoops in with a bucket to douse the flames. It fetches more water on its own, too.
