The first major rehearsal of a joint operation featuring fighter jets, Airborne Warning and Control System (AWACS) planes, helicopters, missile batteries and air-to-air snipers took place two hours north of London on Wednesday, in a plan to supplement Britain's normal airspace security for the games.
Apparently they plan to put snipers in helicopters to shoot any dodgy looking pilots!
I can't see that working very well,... what do they expect to achieve apart from uncontrolled pilotless aircraft filled with fuel and people, zooming across london.
