Mike Tee...they left as much for financial reasons as they did because of the growing airport traffic, therefore the argument could be made that they did in fact prove that skydiving and commercial aviation can work together. The Hawk you mention in your scenario would have got in, you're very naive if you think there wasn't procedures in place to deal with such a scenario. And as for the noise comment, as loud as the Airvan may be, I will resign from the airport to become a binman before that thing adversely affects anyone's quality of life...people love to complain that's the real problem.
