I'm totally in agreement that armed forces are there for reasons you described. But an "air show" is a massive and sometimes separate Venn diagram. There are air shows where main thing is thousands of private airplanes coming from across the country to be together and meet up and have fun.
Put it other way, if armed forces decided it's not worth the recruitment investment and pulled out, air shows would still happen :). For most sizes air shows, the biplane aerobatic stunt done by a crazy local 50 year old real estate agent, is way more fun than the c5 galaxy transporter showing "short takeoff" :-)
People fly air shows with crop dusters.
Why do people go see rocket launches?
It's a superset of the reasons you poorly articulated, and those reasons would include the fact it's cool. Cool things can help both recruitment and morale, and the US military seems to recognize that: https://armedforcessports.defense.gov/Sports/Esports/
If this is just meant to be another comment on the situation which comes with an implicit grain of salt, then the browbeating doesn't make sense.
> So in response you select the most naive take?
As well as your reply to me now, as having an unduly negative tone... at least, given the lack of substance or importance.
(Ironically, I have less of hang up on meaningful arguments delivered with edge than most people.)
Both are unprofessional comments, but only the original was dishonest. The "too many comments" shtick is a thought terminating cliche that shouldn't be encouraged on HN.
The military participates in airshows because it's good for morale, because it helps showcase capabilities, because it's good PR for military expenditures, and because it's good for recruitment. All of these effects are mostly because it's cool.
The other people flying in airshows are flying there because they love aviation and because it's cool (not so much the money :)
Maximally correct answer is "there are many reasons with complex interplay", and those reasons do include the fact it's cool! Being cool has interplay with morale, recruitment, and even their ham-fisted attempt at referencing geopolitics.
They'd be "more right" if they said in addition, but they just straight up said "No."
(Also where did you read a too many comments shtick?)
