In the process of refurbishing the damaged, rusted hulks of the M1 from the battlefield .. they're made new from bottom to top.
To get rid of the rust and dirt, there's this special "hangar" .... 8 ton, 30ft. high doors... that's how huge it is.
A special huge chain assembly tows the tank so that it's eventually hanging vertically, upside down in this hangar. Then, for 90 mins., jillions of microscopic steel ships are
sprayed under high speed at this hulking tank, as it slowly
rotates in the chamber.
At the end of 90 mins., the tank is spotlessly clean steel .. brand new .. no rust. And it's ready to begin the journey for retrofitting, adding the rebuilt engine (which
is a jet aircraft engine) and all the telemetry and electronics, artillery, etc.
It's an amazing tank, and this show is fantastic.
