Accidental heroes : a novel
(Book)

At New York's John F. Kennedy airport, two planes have just departed for San Francisco: one a 757, another a smaller Airbus A321. At a security checkpoint, TSA agent Bernice Adams finds a postcard of the Golden Gate Bridge bearing an ambiguous message. Senior Homeland Security agent Ben Waterman still grapples with guilt after a disastrous operation in which hostages were killed. What does the message mean, and which flight is involved? Passengers, crew, and experts on the ground become heroes out of necessity to try to avert tragedy at the eleventh hour.
