Discover Magazine published a story on a drone rescue near the Kilauea lava flows in Hawaii. "The USGS team was able to find the resident with the drone and have them follow it out of the lava flows and vegetation to safety. Think about that: A drone used to map the flows then used that data to help guide a resident from the hazard zone! Not only that, but the drone was able to send real-time images and video of the lava flows to emergency responders to help them more efficiently help residents and know where to send people as the evacuation progressed."
