I visited this museum numerous times over the last 11 years of living in the Richmond area, including attending aviation safety lectures there.
The museum, though small, was a real treasure and each visit usually afforded an opportunity to meet someone who would share some kind of personal experience related to the the aircraft displayed there.
The 38 aircraft that called this place home are supposed to be relocated but I don't know where or when, with the exception of the SR-71 Blackbird.
The SR-71 has been relocated to the Science Museum of Virginia on Broad St. In Richmond as part of there exhibit "Speed". I have not been yet, but plan to.
