Part 107 UAS pilot reported a flyaway. The UAS was later recovered with minor damage.

Narrative

When I went to fly my DJI Mavic Air 2; it suggested updating the system. I updated the system; and it said; 'Successful Update; ready to fly.' I went to Air Aware; filed a flight request; and got authorization to fly. After pre-checking the aircraft; I lifted off and got to 380 feet; and as I proceeded to fly over an open field 200 feet away; I lost signal to the drone; and the drone continued to fly away. I had returned home set to see if the signal was lost; but I watched the drone fly behind a tree and lost sight of it. I notified the Police since I had seen the medevac helicopter and the police helicopter fly over my residence. They said they would notify the FAA; the Hospital; and the police on the ground since the aircraft was not flying. I fly with a Firehouse ARC V drone strobe; day or night; and advised the police of this. After 30 minutes; the drone did not reconnect and did not return home; so I went to the DJI program; found out its last location; and went to it. The drone was found in the front yard; about 1200 feet further than it was on the DJI Locator app location. But the battery and strobe were missing. We searched the area yesterday evening; night; and today and did not find the battery or strobe. I notified the police via a non-emergency number when I found the drone. I notified DJI of the flyaway; and then sent it in for repair today since one of the landing legs broke off. Nothing on the ground was damaged; and there were no injuries.
