I'm going to be in Germany for about 5 or 6 weeks July 10 to August this Summer.  I'm looking for some direction in finding worthwhile military history places to visit while in Germany.  I know there are a couple Bf 109s that fly, including a109G10 , but I have been unable to find out information on the net where or when they fly these aircraft.  I will be traveling throughout by train, but I'm still finalizing where to go.  I haven't ever heard of any great military museums that exist in Germany, but perhaps I missed something.  
Thanks
