1. A fire-fighting system for airport runways, which comprises:

  • a plurality of hydraulic monitor units disposed at spaced locations along a runway for airplanes, said units being so located that jets therefrom blanket said runway with fire-fighting fluid, each of said units including a foundation defining a chamber and recessed below the level of the ground, each of said units also including a high-volume hydraulic monitor mounted in said chamber and movable between a retracted position recessed below ground level and an operating position at which at least the nozzle of such monitor is disposed above ground level, said nozzle being mounted for pivotal movement in both horizontal and vertical planes whereby said nozzle may be directed at the source of a fire on said runway, each of said units also including a hatch which is closed over said foundation when said monitor is in said retracted position and is open when said monitor is in said operating position, means to supply fire-fighting fluid to said monitor units, and centrally operated remote-control means connected to all of said monitor units to operate said monitors between said retracted and operating positions, to shift said hatches between said closed and open positions, to direct said nozzles in said horizontal and vertical planes, and to control the supply of fire-fighting fluid to said monitors.
