The AP reports that the first anti-missile defense system has been installed for testing on a commercial jet
, a FedEx cargo carrier. The system is intended to detect the launch of a shoulder-fired missile at takeoff or landing, and disable the missile with a laser beam. Sen. Barbara Baxter (D-California) is one of the supporters of the system. She and other members of Congress are hoping to equip all US commercial passenger liners with this system in 20 years, at a cost of billions of dollars. Is this good common sense or the costly future of a society hobbled by fear of terrorism?
