My Drone Under Attack by Supersonic Flying Object

My hobby is shooting natural landscapes with drones. A few days ago, I went to Surisan(mountain) near my house(South Korea). But suddenly, during the shooting, the drone began to shake violently. At first, I thought the wind would blow hard or the bird would attack. And when I got home, I looked at the video on my computer, and I looked at it very carefully, and there were supersonic objects that I couldn't quite understand. Please identify those objects. An ornithologist or scientist. Anyone will be fine. I also promise a reward worth $200 to those who reveal the supersonic objects' identity. I'm so curious about this. (My neighbors say they will also pay a reward for this video. We'll notify you as the reward increases.) There's a lot of similar videos on YouTube. Link the first image that appears. https://youtube/r855Hp4nbGQ (It's my first time editing video, so I'm not very good at it. Please understand.)
