Our field had a vist from a......Govt. Employee, who was visiting all RC fields in the area......with some information on what to look for concerning possibly suspicious individuals with regards to terrorism. The general criteria was that such an individual would be a pretty obvious newbie to RC airplanes, interested in larger scale, fasterairplanes.

This thread possibly raisesa flag for me as well. I'm certainly not drawing any conclusions or making any concrete accusations, but the OP and subsequent responses doesn't ring true to me.
