Yes indeed Genghis, good learnings will emerge from the report for sure, which hopefully will result in modifications to current procedures rather than draconian restrictions.
Perhaps a recommendation to tighten up what the Air Show Director can authorise would be good. Currently the director must advise the pilot of his minimum permitted display height in writing (and by phone or in person nearer the time). Maybe a good idea for the director to physically see the whole display to assess its safety before authorising it?
