The photos were taken at the Royal Army and Military History Museum (Musée Royal de l'Armée et d'Histoire Militaire / Koninklijk Museum van het Leger en de Krijgsgeschiedenis) in Brussels , Belgium.
Mike adds: Like the Soesterburg museum in NL, this is another museum that lets you get pretty close to the airplanes without much trouble.
