The pressurization system had been activated, and the plane was now on autopilot. There would be no immediate problem for the time being, so Chen Mo did not rush to take control of the aircraft. Instead, he ordered J.A.R.V.I.S. to investigate the cause of the accident.
J.A.R.V.I.S. immediately hacked into the networks of Los Angeles International Airport and the airline operating the flight, searching for relevant information.
To J.A.R.V.I.S., every system connected to the public network was completely undefended. Firewalls were practically nonexistent.
Very quickly, J.A.R.V.I.S. found the key information, and an organized file was displayed before Chen Mo.
The rear cabin door of this Boeing 747 had previously been found to have problems on several occasions. Once, after takeoff, the aircraft had been forced to make an emergency landing because the rear door could not seal properly.
To be safe, they had specifically inspected the rear cabin door before this takeoff.
Yet it was precisely this inspection that planted the seeds of the accident!
The ground maintenance engineer had switched the aircraft's pressurization system from automatic to manual, pressurizing the plane without starting it up, much like submerging a bicycle tire in water to check for leaks.
But after completing the cabin pressurization test, the ground maintenance engineer had evidently forgotten to switch the pressurization system from manual mode back to automatic mode.
And during the subsequent flight, the pilots had failed to notice this tiny detail.
Thus, as the plane climbed, the pressurization system that should have activated automatically never started.
Such an error had never occurred before, so when the two pilots noticed the temperature in the cabin dropping, neither of them thought of the pressurization system. Their first suspicion was the air-conditioning system.
With the oxygen level rapidly falling, the two pilots had both passed out
