Saw a posting on the Neighborhood web site regarding a Mavic 2 a friend found in about 3 feet of water at the beach near their house. He said the lights were flashing when he found it. I suggested he get the battery out and place the drone where in might dry out. There was no name or registration number on the drone. Meantime I told him how he might find the owner. Well the next day he gets a call from a young person who lost the drone and stated that he was an FAA drone pilot, Part 107 I assume. He came over and picked up the drone. So here is a "part 107" pilot with no markings on the drone and worse yet, he was flying within a mile of an airport with a control tower, right under the approach to a runway. A runway I frequently use when I fly my Cessna 172. Not good!
