Used to have fun back in my childhood playing Round Sounds from a set of speakers on the roof of the apartment building. People on the street started looking for the airplane.
It'd probably much cheaper just to fly a set of drones in the area rather than deploy a full PsyOps team and gear. They do it with actual jets while the actual attackers are flying in fast and low from the opposite direction now that you've sortied your defensive aircraft towards the bait.
