I don't think some people understand the concept of visual perception, when it comes to the planes flying "dangerously close to the city". The jet that looped around commerce court within "several hundred feet" was probably well over a half kilometer behind it. The jets travel out over my house on their turnarounds (east of Parliament), but yes, it does look like they are just behind the CBD buildings. Yes, there have been air show accidents in the history of mankind, but these are some of the best pilots in the world (Blue Angels specifically) and the risk of an accident over the city grounds is absolutely minimal.
Why the hell do some people live in cities? I can't comprehend it. I've said it in several threads, move to Niagara-on-the-Lake. Oh but wait, you'll get all upset about the hoards of people that arrive for the Shaw Festival and make a big commotion. Nunavut was a good suggestion.
