During the week actually so you can go into the Fighter Factory and see the guys and what they do best. On the weekends the FF is closed to visitors. However the main museum, WW1 hangar and Luftwaffe Hangar are open on the weekends.
Hey Dave, I will be out that way taking care of some property for relatives in April, the 14th-19th. I am going to take a day and visit the museum. Was wondering if you were going to be there.
