Originally the new terminal was to cater for Sucking/Scot airways, some of the routes no longer operate and to facilitate diversions from other airports, mainly Stansted.
Looks like from the thread, that they have grander ideas. I wonder where they will get enough radar controllers to operate H24?
Essex radar could well collapse if Cambridge got significantly busier. If a carrier did move flights from Stansted, the vacated slots would soon be snapped up, thus massively increasing the flow of traffic through the BKY VOR area!
