dicksoucy,
Excellent point. I know that a lot of people think that it's not going to happen to them, but it does happen. We had something happen at our field that made me thing twice about flying alone. A pilot at our field was adjusting his needle valve and he put the hand up against the prop. It opened up a pretty good gash on his hand. He said he would drive himself to the hospital to have it looked at, but we insisted that one of us drive him. It's lucky that we did because on the drive (about a 5-7 minute drive) he passed out from the amount of blood lost. Once at the hospital they had to give him blood to replace lost blood. If he had been alone or had driven himself it could have been a disaster. After watching that happen I won't fly at the field by myself anymore.
