In 1959, a cement mixer with a full load of cement, wrecked near Winganon, Oklahoma.
By the time a tow truck came to haul it away, all of the cement had hardened inside of the mixer.
The tow truck was not able to remove all the wreckage at the same time because of the weight, and decided to haul only the cab/frame, and would come back for the detached mixer later - which never happened.
Today, 66 years later, it still sits where it fell.
Locals have painted it and added "rocket thrusters" to make it look like a space capsule.
