Years ago I was part of an incident that shows that accidents can also happen in the most unexpected way. I was flying R.C. in those days , and had just packed up and was starting to drive away from the field. The only remaining flyer was a good friend , an expert chopper pilot.As I drove away I looked back to honk my goodbye. He was just hovering , about 10 feet off the ground , and maybe 40 feet away from himself.All of a sudden , the chopper shed a blade , and it came straight as an arrow right at him, and struck him in the throat.Believe it not , this is the gospel truth. He fell to the ground bleeding badly from the throat, with a long strand of his throat flesh hanging down like a necktie. We rushed to emergency , and luckily enough, they had the right staff on at that time and today , maybe 25 years later , it is just a memory. he didn't fly for quite a while after that. Keith
