Just in from my brother John today, Revell has re-released the visible B-17 Fortress model that has been so hard to find and thus very expensive. Now, it's only $32.00 or thereabouts. Modelers can build the plane with either the standard fuselage parts or the optional clear-plastic side so that you can see the interior.
It probably takes more patience than I possess to make this detailed model, but if you are a modeler, this is the one to get! Available anywhere, but here's the Amazon link as there are some good prices. http://www.amazon.com/Revell-Visible-B-17G-Flying-Fortress/dp/B0012DKP22/ref=sr_1_1?ie=UTF8&s=toys-and-games&qid=1248282161&sr=1-1
