This also from last weekend's WWII Weekend in Reading, PA. I had never seen this plane fly or static before so having this take the place of Fifi was very cool. B-24A Liberator by jbwolffiv, on Flickr
there were a few thousand made, in quite a few variations, but now what are left, 3 ?, and i think only 1 flies
As far as my limited research went, there is one B-24A and one B-24J flying in the world. There are a few static displays as well around the world. Here is another: B-24 Liberator by jbwolffiv, on Flickr
