He only knew how to use the radio because he'd had the pilot show him before take off. He described the King Air as being so different from the plane he'd learned on that it might as well be the space shuttle.
One of the controllers who helped get him down realized she had to simplify the plane for him. He had been struggling with the autopilot and she got him to turn it off and fly it manually. He was fortunate to have some great controllers to help him and a clear day with no wind.
After the incident, he started flying again and went on to become a rescue pilot.
It’s kind of the argument for basic first aid training and other things like that.
