This was taken one morning as part of a distance test flight. I wanted to see how far I could push the drone out into San Francisco Bay and the weather conditions were perfect. There was no wind, and zero signal interference and this shot was 2.8km into the bay. It wasn’t until I got home and started to edit that I saw the ship was called Golden Energy. It seemed more than perfect with the sunrise lurking on the horizon.
