It's in the Paul Garber facility in Maryland, along with several other expiremental aircraft from the 40's. This facility is where they store all the aviation related things that are not on display, or even restored. There are acres of buildings full of wonderful things. It's a great place to visit. You have to make arrangements ahead of time, and when I was there, they only take groups, not individuals. I don't know how big a group has to be, but it would be worth it to get a bunch together.The Flying Flapjack - although the link says Flying Pancake http://en.wikipedia.org/wiki/Flying_Pancake
The article says one was given to the Smithsonian - but I've never seen it.
