Tuesday, September 11, 2001, a temperate and nearly cloudless morning over the eastern United States. Millions of men and women ready themselves for work. Among them is an air traffic controller in Boston, Mass. Based on sheer intuition, he will break all protocol this morning, alerting the Air Force that a potential disaster is unfolding on his radar screen. Air Force Colonel Bob Marr, commander NEADS (North East Air Defense Sector] will scramble all he has to try and avert a catastrophe - but it will consist of only two F-15's that begin "searching for a needle in a haystack". Meanwhile, a group of 19 young men armed with simple box cutters literally fly under the radar into the World Trade Center , The Pentagon, and a Pennsylvania field. From the viewpoint of these two key theaters of action, Air Traffic Control and the U.S. Air Force, "Seconds From Disaster: 9/11" deconstructs, second-by-second, the tragic events and security lapses that led to the worst attacks on American soil since Pearl Harbor. The episode contains chilling testimony from the Air Force Colonel Bob Marr , Air Traffic Controller Dave Bottiglia, Ben Sliney, the man who makes the call to ground all the planes in the air over the U.S. and John Farmer Senior Counsel for the Presidential Commission. The question has to be asked: even on the day, could 9/11 been stopped?
