On other fund raising ventures [TV'a'thons etc.] the pledged figure is usually exceeded by quite a margin. My pledge to help 558 stay airworthy was always made with a mental note that when asked to honour that amount I would actually double it. One or two others I have spoken to said they had had the same thought. I will await the final tally with interest.
Be nice to know how the money will be used. Transparency would silence the doubters - hopefully!
