However, this huge gap in America’s air defenses hadn’t escaped the attention of the Air Force Office of Experimental Avionic Research in Colorado Springs. These guys, who had the sexy military-style acronym AFOXAR, had been working on the problem with some quiet help from NASA and DARPA. Their first conversion target was the BBJ, Boeing Business Jet, the largest and therefore most dangerous aircraft of the American private jet fleet. Their scheme was to come up with a small, secret autopilot that could be quietly installed inside jets and then triggered remotely during emergencies. Then the autopilot would guide the plane and its baffled terrorists right back to earth, and the waiting arms of fully informed police.
