I only saw this after watching the video back. this was my first ever video that i took with my drone. after the first crash, as i was carrying in the drone back to a flat rock so i could take off again, the video camera was facing up and caught this black thing overhead.
i did not see or hear anything when i was out there and only saw this in the video.
here is the link to the video. i just put it up on youtube. maybe someone will know what it is.
