The problem with these fundraising ideas is that they, without fail, appear small-beer and a bit "village fete". A day for 30-odd people at a shooting range, the risible "Welcome Home Day" last autumn which featured apple-bobbing as one of the attractions on it's official poster, a stall at a Christmas market with not enough stock, and now a couple of chaps driving a car round to a few museums. A multi-million pound project HAS to think big, and BE big. The national media, and even the local press aren't going to drop everything to film a couple of enthusiasts in a Subaru driving to a few wet, cold aviation museums.
To get in the press, and especially to get on TV the story MUST be visual - ie have an element which lends itself well to either photography or film. Even in a regional newsroom the editor will have maybe 50 possible stories at the start of the day, without taking into account stories which break in the hours before the programme. To cover these stories they'll have perhaps six reporters and maybe only three or four cameras, so the editor has to be selective about where to deploy resources. I will tell you now, the prospect of filming a couple of spotters at an aviation museum driving a heavily-logoed Subaru (From experience, I can tell you that ITV News are VERY careful about showing anything which might be even loosely construed as product-placement) is highly unlikely to make the programme, and even if it did, it would be no more than a cursory ten second filler story.
Sorry to sound so negative, but the bottom line is that to have any hope of raising awareness, the team need to be a lot more savvy in HOW to appeal to the media.
