A figure of 8 and a climb & dive isn’t a waste of tax payer money.
The aircraft is going to fly anyway - and do the various drills and maneuvers as it / the pilot should.
It depends on if the this was done instead of the usual drill/maneuver and whether itr was a sufficient for the usual maneuvers.
Kids too young to understand won’t get it, kids that get it may likely think it’s funny.
It would’ve likely dissipated soon afterwards anyway.
still I don’t think they ought to be doing it. We don’t need our skies to look like the wall of the high school boys bathroom.
