Last Drone Flight! On landing, boat swung and it hit lifeline and splash, Gone! 🤦‍♂️

So I was shooting some shots at this anchorage next to the Welland Canal and as I went to land it on the deck, the boat swung on the anchor and the drone drifted into the lifeline. It sensed the lifeline below it and thought it landed and the motors shut off and it flipped off the boat, into the water to never be seen again. 🤦‍♂️
This footage came from the cached footage stored on my phone from the controller. Sad 😔
