Stilton, while on 31 Sqn I did take the GR1 along the odd airway and do a little procedural work but it was not great and required planning and loading into a tape.
At that time Bruggen did sometimes use civil airports like Dusseldorf as diversion options but when poss preferred a local military base like Norvenich, Gielengkursian (spelt wrong sorry) etc.
