We are all responsible for our action, seems that it is not taught anymore. Has it been explored that maybe these real close incidents are perhaps intentional, and intended to do harm to the planes that being said the real answer is most likely someone acting negligently. Flying that rc'rs do its generally hard to have intentional mid-airs watch combat events but sharing the air. Like it or not drones are here and can you imagine the technology they will have in ten years.
