The Cessna Pilot

Leave it to CNN and FOX to freak out everyone about this suicidal Canadian Cessna pilot who flew into the US. I've been watching all these experts talking about the "what ifs". What if he was carrying a dirty bomb? What if he was planning to crash into a government building? and so on... There are hundreds if not thousands of trailer trucks and vans which can carry a bigger payload than this Cessna crossing from Canada and Mexico into the U.S., not to mention all the un-inspected cargo that comes on boats. This poses more danger than a suicidal pilot.
