December 11, 1994. There are 293 people headed for Tokyo aboard Philippine Airlines Flight 434, each of them unaware that a terrorist planted a time bomb under one of their seats. The midair explosion kills a passenger, cripples the plane, and forces the pilot into the most challenging landing of his career. These are two chilling stories, one aboard the flight, as passengers pin their hopes on the skill of the cockpit crew, and the other across the globe as authorities race to catch a terrorist before he can strike again.
