But nowhere in this 1080p video you can see any special quality of the C700 or something that dozens of other cameras couldn't have delivered in the same way.
Which is true for most, if not all, promotional material for any camera (but the Huawei P9...) - given the skills of those behind the camera(s) often matter a lot - sometimes more than the gear used. In this situation, also the skills of those in front of the camera...
And yes, being shot with a Canon camera it was sent to a Canon-related site - should they have sent it to a Sony or Alexa site?
Anyway, still you miss the original post meaning - the video is spectacular on its own, regardless of the camera choice. And being able to setup and perform this kind of shooting is appealing too on its own.
Sure, the fact it was made with some Canon cameras (as well as GoPro) is still a good promotion for Canon (Canon Switzerland supported the filming).
Feel free to tell the makers what you think about their choice here: http://www.lauschsicht.com/c-series-patrouille-suisse-airshow-behind-the-scenes/, maybe they will answer you...
