Story Structure — 5 Plot Phases
Storm Over the Airways
A worldwide electromagnetic storm cripples communications and damages the satellite system. The resulting debris and system malfunction threaten air traffic along the U.S. east coast.
Key Events
-
Electromagnetic Storm Begins — A major electromagnetic storm cripples communications worldwide.
Location: Worldwide airspace
-
ACAT Satellite Is Struck — The new satellite-based collision avoidance system is struck, sending debris toward Earth.
Location: Earth orbit
-
Air Traffic Becomes Vulnerable — The malfunctioning pilot-project system places east-coast air traffic in danger.
Location: United States east coast
-
Two Aircraft Converge — A commercial airliner and Air Force One are placed on a collision course. Characters: Passenger
Location: U.S. east-coast airspace
-
Errant Commands Spread — ACAT begins sending erroneous commands that endanger both aircraft.
Location: ACAT-controlled airspace
Collision Course
The malfunctioning ACAT system sends dangerous commands to two converging aircraft. Bob Abbot recognizes the danger and attempts to ground all traffic despite higher directives.
Key Events
-
Errant Commands Spread — ACAT begins sending erroneous commands that endanger both aircraft.
Location: ACAT-controlled airspace
-
Satellite Debris Reaches Cities — Failing satellites produce debris that strikes major populated areas.
Location: Populated areas of the United States
-
Debris Prompts FAA Contact — After encountering debris, a scientist contacts Cleveland FAA controller Bob Abbot. Characters: Bob Abbot
Location: Cleveland
-
Bob Abbot Challenges Directives — Bob Abbot overrides top-level directives because he wants to ground all traffic. Characters: Bob Abbot
Location: Cleveland FAA control center
-
Lightning Strikes Both Aircraft — Repeated lightning strikes partially disable both aircraft. Characters: Passenger
Location: Severe electric storm
Systems Under Fire
Lightning damages both aircraft while ACAT disrupts the fighter escort. The commercial airliner loses both engines but restarts them before the approaching impact.
Key Events
-
Lightning Strikes Both Aircraft — Repeated lightning strikes partially disable both aircraft. Characters: Passenger
Location: Severe electric storm
-
Escort Fighters Lose Control — Damaged satellite signals cause ACAT to disrupt the escorting F-16 fighters.
Location: Airspace near the aircraft
-
Airliner Engines Fail — The MD-80 loses both engines while approaching the collision danger. Characters: Passenger
Location: U.S. east-coast airspace
-
Engines Restart Before Impact — The airliner's engines restart just before it impacts. Characters: Passenger
Location: U.S. east-coast airspace
-
Sidewinder Hits Airliner — A rogue Sidewinder missile strikes the converging commercial airliner. Characters: Passenger
Location: Converging flight paths
The Midair Disaster
A rogue Sidewinder missile strikes the converging airliner, and the two aircraft suffer a glancing collision. The airliner crash-lands in Cleveland while Air Force One remains endangered.
Key Events
-
Sidewinder Hits Airliner — A rogue Sidewinder missile strikes the converging commercial airliner. Characters: Passenger
Location: Converging flight paths
-
Aircraft Clip Each Other — The two aircraft suffer a glancing collision. Characters: Passenger
Location: U.S. east-coast airspace
-
Airliner Crash-Lands — The damaged commercial airliner crash-lands in Cleveland. Characters: Passenger
Location: Cleveland
-
Rescue Mission Is Launched — An Air Force C-130 Hercules attempts to rescue Air Force One's passengers.
Location: Airspace near Air Force One
-
Rescue Effort Fails — The rescue effort fails to bring the aircraft's passengers to safety.
Location: Airspace near Air Force One
Override and Landing
A rescue attempt fails, and electrical impulses kill the flight crew aboard Air Force One. The ACAT system is overridden, allowing manual control and a landing at Detroit.
Key Events
-
Rescue Effort Fails — The rescue effort fails to bring the aircraft's passengers to safety.
Location: Airspace near Air Force One
-
Flight Crew Is Killed — Electrical impulses affecting Air Force One kill the flight crew.
Location: Air Force One
-
ACAT Override Attempt — The president's daughter attempts to disable the malfunctioning ACAT system.
Location: Air Force One
-
ACAT Is Overridden — The ACAT system is finally overridden, removing its control over the aircraft.
Location: Air Force One
-
Manual Flight Control Restored — The president takes control of Air Force One after the flight crew is lost.
Location: Air Force One cockpit
-
Air Force One Lands — The president brings Air Force One into a landing at Detroit.
Location: Detroit
