The above post is #230 (page 16).
There is a park with old airplanes on display near the road to that museum. Be very careful if you take pictures. You are being watched. They will come to you with sirens blaring if they think the photo captures more than the airplane, such as a building (even though there are bushes and trees blocking view of any building). Better yet, enjoy the planes while you are there, remember the model, then look up the model online if you want to see a picture of it.
