100% agree, people who are not trained have a lot to say about things they do not understand, if one took the claims at face value there would never be another airshow in this country or the world again. Just because someone is a pilot doesn't mean they are experts, any more than driving a car gives you the professional knowledge to comments on formula one racing, an airline pilot cannot make a determination on the actions of a test or stunt pilot etc. In this case the permissions were reviewed and approved, and yes one of the aircraft has since been deemed to have been to low and that is being investigated and will be dealt with accordingly once a final determination has been made.
