I would hope that Pulse1's feedback woild be taken onboard, but I think the distinction needs to be made between the organisers (ie flying participation etc) and the framework they are forced to operate within by the contractors.
DB - I know the effort the Ship's Company/aircrew etc will have expended and it typifies the whole approach to airshow organisation (using outside "event" contractors) that spouses were charged to attend what should also be a family event in support of the Squadrons. I'm not suggesting a free-for all, but genuine NOK should not have to pay to attend. (The general public do that in anticipation of seeing a full and varied air and ground display that showcases the role of the Armed Forces, and Fleet Air Arm in particular @ Yeovilton.)
