Meet the “Big Wind” a.k.a the most powerful fire truck in the world. According to the video description,
Designed by a team of Hungarian engineers originally as a means of mass decontamination for Cold War-era tanks in the event of a CBRN (chemical, biological, radiological and nuclear) attack, this fire-fighting chimera has found a surprising niche in the modern world: putting out oil well fires. The Big Wind is one part T-34 tank and two parts MiG 21 jet engine. Specifically its a T-34 tank chassis with a pair of Mig 21 jet engines mounted to its roof.
Did I mention it needs 3 people to operate it? However you look at it…this vehicle is a beast.
