The Enterprise shuttle Galileo was lost for many years after the show. Its a pretty cool story, tracing her design and life on set, to its eventual donation to the Braille Institute in Los Angles for kids to play on, to the front yard of a local man who bought it for his son (the neighbors hated it so they petitioned to have it removed). From there the shuttle moved to the California Creation Convention . . . where it slowly dissolved.
And her story goes on. You have to scroll down a bit to it all but really a cool read.
