A lot of people commenting on this event for the media are not as knowledgeable as they think they are.
I'm not sure if it has been covered on this thread but a fly past doesn't become an aerobatic manoeuvre until the nose passes 30 degrees nose up. Therefore it is perfectly permissible to fly past at 100ft, pull to 30 degrees, and when passing 500ft commence an aerobatic manoeuvre.
Therefore pulling into the vertical after a 100ft fly past isn't necessarily rule breaking if done correctly.
Very few pilots plan to have a crash, so if one occurs there's always a reason. Let's wait until the final report is out, learn lessons to try to prevent a similar accident and continue to enjoy air shows.
