I agree, there is plenty of room either side of the main gate for a Fouga "gate guardian". (N.B. Not Fouga 220 mind, which should be retained for indoor display, having being the last Fouga in AC use)
A directional sign, on the N7, which reads "CASEMENT AIR BASE - Home of the Irish Air Corps" would also be an excellent idea.
Although, perhaps the way things are at present i.e. the debate over the future name of the AC, the lack of an AC Museum etc. are the reasons we have not seen such developments.
