Jim, I left the newsgroup rc.models.rc.air to avoid this kind of personal attack. The fact that you and I disagree does not give you the right to impugn my character. I have asked the moderator to remove your post.

Your analogy is not a good one. I never implied that totally uninvolved parties can be held liable. In this case the flier was an AMA modeler, and the AMA advertises that it insures its members. That sounds like a lot of involvement to me. A lot more than in this case, which put the association out of business: http://www.kkrlaw.com/changes/safety_standards.htm
