I was at a talk some two years ago in which the Airport Manager described re-aligning the runway and actually making it longer. From memory this was to be more to the south of the existing tarmac than to the north. He stressed that it was not necessarily to allow larger aircraft or commercial operations, more for safety reasons and to allow all new facilities on the opposite side to those in existence. The funding was apparently in place at that time for both the new runway and new tower/hangar/fuel facilities etc. Forgive me if this old information is of no consequence or has already been discussed.
