I recently had occasion to speak with the head of the olympic side of DAP and she didn't even realise that the area we were talking about was affected.
This is probably the same person (Wg Cdr) I wrote to last year, and twice since, expressing my concerns about the published Olympic rules effectively barring helicopters from operating into and out of Central London. This may have been done deliberately, I don't know. The thing that cannot be addressed is how to effectively clear security before departure, as required by these new rules. There is no provision for this to be done. In any event, the rules as published are ineffective in that they would not prevent a helicopter (or many types of light aircraft for that matter) landing en route to London after doing so, while still appearing to comply with the accepted flight plan and security procedures. It's a total mess.
