Puzzle: Manfield Air Spectacular

[stonepicnicking_okapi]

I am not patriotic, so I resisted getting this puzzle, even though I'd seen it in the catalogue for a long time, because of the red-white-blue motif (Charles Wysocki did an even worse one called 'So Proudly We Hail' which is mostly flags and bunting). But I saw this one in the store on the last day of my shopping before the pandemic lockdown hit in March, and I thought, why not? So I saved it for the Fourth of July weekend. It was fairly easy except for those slivers of clouds and blue.
