Smithsonian denies it:
I sure hope so.
Thanks for the link.
They may be saving it for the new museum of African American history that they are building next to the Washington Monument. I just did the Smithsonian with some of the kids in my family. I found the museums downtown to be run down and in need of a rehab. The air museum out at Dulles is awesome. Parking is stiff, but they have extended hours in the summer and after four the parking is free.
