Just read that the Smithsonian has first dibs on the Shuttle Discovery when they retire those spacecraft. Other museums have to try and get approval for the last 2 shuttles, but they will have to pay $43 million to get the old bird in their collection. No, NASA isn't selling them, but it will cost that much for "shipping and handling". It will be expensive to "safe" the orbiters for display, remove the dangerous parts, install replica engines (optional), and ship it out on the 747. I guess I could upgrade my Museum of Flight membership to a higher level if that means we can get Atlantis in Seattle!
