Factual error: When Matrix escapes from the landing gear of the plane, he opens a hatch to access it, but doesn't close it behind him. This would have later led to the cabin depressurizing and the plane plummeting to the ground.
Suggested correction: No, it wouldn't. The entire wheel well of an airliner is pressurised - otherwise the tyres would explode! Once the undercarriage is retracted (typically at less than 1000 feet) the pressurisation problem no longer applies. Plus, the access door opens inward (like most aircraft doors), so the pressurization would force the door shut against the frame anyway.
Wheel wells of airplanes are not pressurized. Airplane tyres are about 145PSI at ground level, and at altitude they'd be under 160PSI, nothing radical for tyre manufacture. Plus as the air temperature decreases at higher altitudes, the tyre cools and the internal pressure drops, more than compensating for the lower external pressure.
Wheel wells of airliners are always pressurised. Those stowaways who hide in the wheel wells die from hypothermia or are crushed to death by the retracting undercarriage. They do not suffocate.
