The military aviation museum near my home has very interesting aircraft on display including this mustard yellow helicopter (Piasecki HUP-2 "Retriever"). They also have a restored German Messerschmitt ME262-B1a that I haven't seen up close yet. The visiting hours for the aviation museum are quite limited and I never seem to have the available time to visit when the museum is open. Someday I'll make the time to dedicate a day and a gallery to this museum.
