I seem to remember over the last 20 years or so Newcastle also have produced numerous "master plans" or at least development plans and if I recall ,non of them have come to fruition? Now that is from a moderately successful airport.
DTV which was once a moderately successful airport circa Globespan days is now firmly in the doldrums with a( another) master plan on the drawing board.Therefore it's not without possibility that this also is just pie in the sky..thought up to keep the councils,locals and business community happy?
