Allow me to introduce the “Big Wind.” The fire truck was designed by engineers to as a means of mass decontamination for Cold War-era tanks in the event of a CBRN (chemical, biological, radio-logical and nuclear) attack. Now? It puts out oil-well fires.
According to Extreme World and Engineering, The Big Wind is one part T-34 tank and two parts MiG 21 jet engine and needs three crewmen: a driver inside the tank to steer and stop it; a controller in a rear cabin at the back of the platform to run the jet engines and the water jets; and a fire chief who walks about 15 feet away, issuing orders to the two other crew members through a remote-control unit. When the water is turned on, the six nozzles above the MiG engines unleashing an immense blast of water that mingles with the jet exhaust and becomes a ferocious spray of steam. The water is moving at a maximum rate of 220 gallons of water a second, or twice what an average U.S. household uses in 24 hours.
Needless to say, this thing is a BEAST.
