Bizarrely, as someone about to embark on becoming a "fixed wing jockey" (sorry for barging in chaps and chapesses!) I would love to contribute towards what I see as a very worthwhile cause. Unfortunately I am not able to at the current time (due to impending huge costs of training!) but I did want to ask if anyone had considered approaching a high profile figure head for this someone like....ooh, Richard Branson? It's right up his street, would solve funding needs in one hit, and raise profile for both Virgin Atlantic, him and the cause....I'm guessing that fixed wing will be with you on this also...
Sorry if this is of no use, but please accept it's at least well intentioned, even if ill informed!
Best of luck with it whatever happens!
