Well..that’s an remarkable answer.
Well .. it's remarkable that some FReepers are unable to consider the fact that a Cessna 172 being trailed by F-16s can still be shot down if circumstances demand it, even if the original intent was not to do so.
The message the terrorists will take away from this is that the plane was quickly spotted, intercepted, and trailed. Even if certain FReepers cannot connect the dots, I'm sure the terrorists can and will: this is a non-starter as a means for serious terror attacks.
