Which is what today's practice was all about. If I understood correctly, this is a volunteer drone squad, and they were practicing the three kinds of drone flights they have developed for emergencies. First, location -- using cameras, including IR cameras, they fly over an area and identify people waving, bodies, and so forth. So they can quickly direct emergency aid to where it is needed. Second, communications! They have drones with speakers, so they can fly over an area and make emergency announcements. Third, supplies. They have drones that can carry at least small medical packs and supplies, so they can deliver those even where emergency vehicles or other aid can't get in.
So, in the event of an emergency, look, up in the sky? Is it a bird, is a plane, is it Superman? No, it's the emergency drones! Looking at you, talking to you, even bringing you the supplies you need.
