Summary...
The AF donated/loaned a Twin Mustang to CAF in 1968. They changed their donation regulations in 1970 and now want the plane back. CAF flew it until the mid-80s when it was damaged, but they have almost returned it to flying status. The AF is now demanding that it be returned to the AF museum, which already has a Twin Mustang. Their primary reason is that they don't want it flying...seriously, would you rather see this thing at a museum or flying at an airshow?
