Oddly enough ...
the State currently owns a second facility with Motorway access AND near by rail link ... no not Baldonnel (no rail link) but Gormanstown (EIGM), which is currently not used. OK, the main runway is short (but could be extended, just look at Weston, and yes I know the 'extension' is currently not 'runway').
No wait, sorry it's a non runner, the government party Finna Fail has promised to give the land to their buddies in the property development sector to build houses.
Oh well
