I went to an air show this w/e and saw the Blue Angels. There were several standing displays on the tarmac. There was one I've never seen before. It was a very small plane, but instead of having a propeller on the nose, it was on the top! And, the thing that it sat on was bolted in, so it was part of the plane and the prop was on the back of the stand thingy! What would this be? I took photos, but don't have them developed yet.
