I have gone twice to see this museum and neither time did I see any directions as to where to go or where to part etc. Is it in the old, original terminal building? where are the airplanes that we might get to see? is it a long walk to the airplane hangars? I am 86 yrs. old and want to see this very much. I have COPD and cannot walk very far (20 ft. at best) so need to know if there are wheelchairs available or are there benches where I can rest for a few minutes before I go on?
