These days there is a by-law that prevents public access to the field at the 27 end of Yeovilton's runway around airshow weekend, but when I last went there, about five or six years ago, there were a good many enthusiasts happily taking photos until the local constabulary arrived. Suddenly everybody was moved back to the other side of the public footpath that runs through the field, and the police remained to enforce it.
While they were stopping anyone else it was okay for them to stand directly under the centreline and take snaps with their camera phones of aircraft on finals. Anyone else who approached was immediately sent back to the naughty step. To this day I am still not sure how they would survive an F-16 dropping on top of them in a way that none of the rest of us would.
