'Will we find out someone has corona virus in 22 days? Maybe. Will anybody die from it? ’
You meant to say ‘one of us’ instead of ‘someone’ and ‘anybody’, right?..
And if you die or a loved one dies or you gave the virus to one of the ‘great unmasked’ at the event and they die…or suffer greatly for the rest of your or their life with one of the devastating effects of this deadly disease…or you or they transmit the virus to a child and they suffer a heart condition for the rest of their lives…
but no worries, right, all were participants in sustained, aggressive testing for the virus all the days surrounding the event and day of. And the sustained, multiple testing was reliable.
THEN you have properly considered risk management (because you or someone still could have been asymptomatic) and the airshow ‘fun!’ during a pandemic without a vaccine was well worth it.
