Their formation "salute, walk to airplane (sic), salute, climb ladder, strap-in, close canopy, salute, start engines, salute, etc" is a complete waste of time! It's like something out of 'Strictly Come Dancing'. Put them well out of the way down at the Harmston end of the airfield, give 'em a 15 minute slot for their display, and be done with it.
If they do insist on their ground display, at least get something suitable noisy to fly while their doing it.
The Blue Angels used to do a similar routine on shutdown. I was watching them at Abbotsford BC when air traffic gave us start clearance for our own display. The crowd seemed to find 4 Olympus rapid starting something of a distraction
Good days.
