The question I keep asking is whether anybody doing the organising has noticed that the airfield is half the size it was in 1982, with many extra buildings (Fire Station eastwards) and ILS and DME aerials that were not there before.
I think the airfield is about 180 acres. Ignoring buildings and other no go areas, if 250,000 people turn up that gives them about 3.5 square yards each although the Pope will probably get a bit more than that....
If I remember correctly, last time a large walkway was constructed across adjacent fields from temporary car parks, which made a gateway on Rowley Road the main entrance. The preparations seemed to take months.... Perhaps they should be getting on with it.......
