Abstract: A vehicle for traveling alongside a burning airplane, on an airport runway, while pumping fire extinguishing fluid on the burning engines, wings or fuselage, is an elongated tank trailer with multiple rear wheel axles and a forward end supported on, and moved by a motorized tractor.The trailer includes a 5000 gallon water tank, foam tanks, a built-in motor and pump, foam spreader bars and an elevatable water tower.The trailer can pump from the nozzle of the elevated tower while advancing at the speed of the plane and includes mobile outrigger means to prevent overturning.

Abstract: A modular fire-fighting unit can be used on the ground as an individual fire piece connected to a water source such as a hydrant, for producing foam or as a nurse unit to other fire apparatus, or it can be quickly mounted on, or demounted from, a portable source of water such as a 5,000 gallon tank truck, for producing foam to extinguish runway fires. The module includes a protein tank, an AFFF tank, an inflexible connection to a source of water, mixing valves and a motor driven pump so that foam may be dispersed from either a turret gun or an airport spreader bar.
