It's amazing really isn't it? Some idiot, probably an expert in onanistic practices, fully expects that these restrictions will give some level of protection to the London 2012 fiasco. Mathias Rust's exploits show what can be achieved and I fully expect that Risk Assessments, Due Diligence and other such management w@nkspeak, let alone getting permission to shoot down an aircraft over London, will prevent a real threat from being intercepted. But meanwhile, virtually all local private flying will be grounded for "Security Reasons." And can the boys in blue dispatch a slow flying aircraft? I wouldn't like to be driving the target, but doing so would probably be safer than taking a walk in some parts of London after midnight.
