Have to agree with Cusco. It would be suicide to attempt to land on the M25 at any time during the day. And, would you want to risk hitting a bridge at night? Then there's the issues of putting other's lives at risk by causing a massive tailbacks and accidents.. .. .OK, the aircarft may get bent up in a boggy field and so may you but that's your problem.. .. .In the USA the volume of traffic and long straight roads make it feasible.. .. .Cheers
