NASA has announced the final destination of one of the shuttles. Sending Enterprise to Intrepid actually makes a lot of sense... of all the surviving shuttles, I would expect only this prototype to be even vaguely weatherproof over the long term. The others are filled with expensive, delicate, never-meant-to-be-out-in-the-rain stuff. One of the remaining three will take its place at Udvar. The destinations of the other two, as the article notes, are still "TBD."
