My long time friend, brother from another mother, and I solved much of the airshow picture taking interference by sending off to an international press reporter organization for press I.D. cards. We would go to the show on Friday, the press day, and get unobstructed photos. That would leave only those acft that flew in Sat. morning. One memorable occurance was a Friday before the show we were photoing the incoming planes when an F-117 came in, the first we had seen. It did not fly during the show, so it was great getting airborne shots.
