Write loads of letters to airport management stating the following:-
1) Bournemouth is owned by MAG. Manchester has been actively helping and developing a top class museum with adjacent viewing park. If the main airport in the goup is doing this why is Bournemouth doing exactly the opposite? Additionally the Museum gains a lot of income from visitors who come to use the picnic/viewing area. This source of income will disappear and will probably make the museum unviable if it moves to a hangar on the north side with none of these facilities.
However 1) will probably not carry any weight. However continue with following:-
2) Existing car parking is already a joke. Car Park 2 (not sure of numbers, unfortunately) is diabolical. The route to the terminal involves pushing a baggage trolley over rough surfaces and kerbs, avoiding deep puddles when wet. When dry vehicles moving in the car park throw up dust resulting in returning to your car after a period away to find it absolutely filthy! No doubt any car park on the museum site will be just as bad and even further to push trolleys to and from the terminal.
3) Area of Museum is NOT shown on Airport Master Plan for car parking by 2008 or even after that. Future car parking areas are clearly marked and do NOT cover that area. Can't they even follow there own plan!!! The airport should simply bite the bullet, admit its car parking provisions are terrible and build a proper multi-story car park adjacent to the terminal similar to Southampton.
Won't make any difference - but at least you can say you tried!
