I truly think this kind of stuff will one day backfire. I'd like to know how many young people became a pilot (or aviation industry professional) after attending this kind of events. I, while working at BAe Systems, managed to get a free pass. I was 25 years old, and was amazed to see A340s making almost 90 degree turns, among many other perfectly safe "stunts" which gave me a truly "romantic" vision of commercial aviation.
Not surprisingly a few years after, with some money earned, I took my PPL. At the end it became a hobby, but 2 of my colleagues, continued to the ATPL, both are TAP Air Portugal F/Os, one is flying the A340/330.
These decisions contribute nothing to ensure public confidence inn the safety of aviation, nor to gather people wanting to join in for the love of it, instead of economics.
It is sad. One day we shall see COMACs deligthing a crowds at Air Shows in China, while the west watches "Mayday".
