I dream of a museum full of this kind of one off machines… and I always thought the only appropriate name would have to include Thunderbirds somehow. I have largely settled on “The Thunderbird Museum of Innovative and Unique Machinery” to avoid potential trademark problems… like the Air and Space wing of the Smithsonian but full of weird and interesting machines like this firefighting tank. Such examples of “necessity is the mother of all invention” are worthy of saving to inspire others to think beyond the conventional form of the solutions they are most common with.
