Just got back into this thread and got to the part that Jeff posted about his Quad recovery efforts. All I will add is that tree climbing with lineman's hooks is way different that climbing a telephone pole ( VLF antenna maintenance USN & New York Tel cable splicer). Tree climbing requires longer and sharper spikes on the climbers. Don't ask how I know
it is Distracting the Engineers attention away from his job, last thing I would want is a Train barreling down the tracks with an Engineer not paying attention to whats in front of him because of a Drone was buzzing around the train, remember the train that jumped the track in Washington because the Engineer wasn't paying attention to his job and was traveling too fast for the corner it was traveling on, it's not about the drone causing damage to the train, it's about the train doing Damage to anything in front of it or around it, 5000 tons of Train can't stop like a car.
