When assignments bring you to pristine lakes, what's not to enjoy. Ok, perhaps not everything was enjoyable; after all, we flew the drone into a tree, which then fell into that pristine lake. However, we were able to recover the drone. After submerging it in 100% alcohol, followed by tearing it down and carefully and cleaning the circuit board, it worked once more. Ah, the joy of hoping your co-pilot is watching the flight path while you're filming. Luckily it was a tree! Lesson learned, though, they will now never take their eyes off the drone. Perhaps they were genuinely amazed at how quiet the motor was!
