2604 - Are you campaigning for a specific exception for FlyingTV, the GA community, or just in general? Either way (and as someone said), you're about a year too late and in any event, under the ePetition T&Cs, even if all of the 'people affected' signed up, there would still be insufficient numbers to even solicit a response from the government, never mind trigger a review/re-think!
I and several others have already suggested alternative methods to make the ATCs' and pilots' life easier during the Olympics, but this is as much about political arse covering as it is about security. Rest assured - nothing will change it now
