I initially thought there was plenty of blame to go around between all three parties involved, but if Rich Hanson's account is factually accurate, I believe the FS pilot is going to come out of it pretty clean. The event organizers are going to have a harder time of it, and the poor RC pilot will probably be pilloried. Here is my reasoning:

The paragraph on "What happened that day" clearly indicates the biplane made an initial pass over the runway. It then went around. I don't care if he was setting up for a landing, doing a smoke on pass, or putting brownies in the oven. At that point, those most familiar with RC model operations (the event organizers, the "air boss" and the RC pilot) should have recognized that there was full scale traffic in the area, and that model operations should cease immediately. According to the AMA report, there was an intentional decision to conduct model and FS operations simultaneously, without identifying how those operations would be coordinated and controlled. That error indicates negligence to me. Whether it was intentionally negligent or just ignorance doesn't really matter.

What was most interesting to me is that much of what was posted on various forums didn't mention any of the facts that Rich was able to draw out. Those facts are crucial to understanding the event, and I think Rich did a very good job of summarizing.
