The Islamic State falls. Brilliant combat jihadist escapes to Syria, forms a terrorist cell, secretly masterminds a scheme exploiting a crack in aviation security. The Desert Southwest Coral Snake is their weapon of choice, pilot and co-pilot their targets. An American airliner is brought down from 31, 000 feet. Jaysh al-Allah, the Army of God, takes credit, paralyzing commercial aviation. US Marine sniper, FBI and CIA resources are brought to bear. A high-altitude drone with laser-guided missiles brings revenge, but final justice is denied.
