Umm, it is the National Air and Space Museum. It, and the rest of the Smithsonian, is a body of the federal government. The government wouldn't be taking the model away from anyone; it's already theirs.
Ah, I see. My eyes skipped over the national part.
I guess it is up to who calls the shots in times like this. Is it really that important that fans want the model stuck behind a glass box for display?
What's the status on the Enterprise-D models? I know one was considered lost, but later given back to Paramount by an employee of Planet Hollywood. It had been hanging from the ceiling at a restaurant and damaged a bit.
