Some time ago, an anti-drone posted that question here...."What good are drones anyway? Good for play & a few aerial photos & videos.....that's about it"!Many realize that drones are capable of being used for rescue spotting. Now they attach loudspeakers to them also so searchers can call out to the lost person(s).DJI has created an interactive map (linked below) showing where & what. I find it interesting. So, when the naysayers claim that drones are only toys, refer them to these instances.https://enterprise.dji.com/drone-rescue-map/I'm not sure how the map is updated however.
