Painted as Netherlands Air Force "X-5", but never flew as such. The real X-5 was c/n 33323. The aircraft seen here is in fact ex Danish AF K-688, and before that it served with the Norwegian AF and the USAF. It was acquired by the museum in 1983, first painted as "ZU-5", and later as "X-5". It was removed from the museum in 2010 for restoration as "T-443" of the Netherlands East Indies Air Force. It is currently on display as such in the new Nationaal Militair Museum (NMM).
