We took some friends to the Military Aviation Museum. The Museum's campus is large - 80 acres, not including the 5,000 foot / 1,525 meter runway. We went to the far end of the complex to visit the WWI hangar, the Cottbus Luftwaffe hangar, and the Goxhill control tower. Because of the distance we drove and as we got out of my truck a big helicopter flew past, just east of the Museum. I managed to get a shot of it over the main Museum building.
