ROD1
Rod you have been reading too much Tom Clancy, the most likely thing to happen is you will get intercepted by a military helicopter if you are heading towards the games but if you are not probably just a call from ATC to check on you. However you will have a much better chance of not hitting all the other traffic that will have been funnelled around the outside of the zone.
If any of you think that the southern UK is going to become a free fire zone I should have a long hard think about how you write the R.o E. to avoid killing people on the ground............. the military will have.
