I'm a simple 'ol country boy,but!
Unless I've understood all this incorrectly,we are expected to send our opposition/objection comments to the people who are actually applying for the extended airspace,ie Norwich International Airport.
In all other planning applications in the UK,the objections are sent to the organisation that will ultimately decide on the proposal,eg,Planning Dept at the local authority etc.
So why can't we do the same here,send our replies to the CAA and Military?
Sorry if I've misread the info.
