Definately agree with the sentiments about less low flying. When I was a young man living near what used to be a WW2 bomber stn and became a very large RRE establishment (BEagle may even have flown his Vulcan out of there) there used to be shed loads of ac. At least twice a day there would be the hi-level pair of F111s. Once, just after Uncle Ron bombed the Libyan colonel, was treated to a hawk and a jp in a rather low (400'?) tail chase over my school. I seem to remember that the hawk was fairly well tied onto the Jps 6! Anyway, getting back to the thread. Don't know whether the FJ over London would have been for anything special but a number of Jag mates have managed to workout that you can fly SVFR (I think) down the heli routes in London. They know who to talk to to sort it out and all that. It's probably just for a jolly, but I seem to remember that the guys used to do it and then go low level with Northolt or BZN. If you're allowed to do something then do it and take advantage.
