I had a chance to visit the Hill AFB Museum. Very good displays and many interesting examples of aircraft and equipment. Best of all, it was free but I recommend putting at least a dollar in the plexi-glass donation bin. "Wendover Willie" is a nice example of a Republic-Ford JB-2 "Loon." These missiles were reverse engineered from pictures and sketches of German V-1s coming in through intelligence sources and later from examples of crashed V-1s from Britain.
