It seems that BA wanted to overfly some key places that had connections with Concorde - Exeter (any idea what that connection is?), Bournemouth (I think that's where one of the Conc charter agents is/were based), and the QE2 docked at Soton. Some quick thinking by certain people in AC Ops at Swanwick used the Jedi mind trick on BA to get them to add NERC to the list!
