Hey Gemhorse, I find it to be a fascinating and fun place to volunteer. Having a passion for aviation and history is nice, but joining and organization that is full of people with the same passion is awesome. I sometimes forget these guys are in there 80s when I see them walking around as spry as the younger guys, lifting heavy stuff, etc. We have annual dues to be part of the organization, but it's worth every penny. Just to get an opportunity to chat with a guy that has been there is amazing.
There is a Wing in Australia and another in New Zealand as well. These are CAF affiliates.
Adler, the CAF wings in Europe are in France and Switzerland. I am sure there are other fine organizations within Germany that are probably doing something similar. Obviously, there are some things in German law that place some restrictions on certain parts of that history, but aviation is neutral, neither good nor bad. It is how and by whom it is used that makes it good or bad. I will ask around the museum and see if anyone knows of German organizations like ours. One guy down there is the son of a German aircraft worker that was bombed by B-17s during WWII, and he joined the CAF the very day he went in and saw the B-17! His son is a regular volunteer. We have a few Germans there, so I think they would know best.
