Passage Summary: Airplanes have great self-flying technology, but people still make mistakes even when the technology is working perfectly.

Reasoning: Automated flight technology is highly reliable for navigation and landing, yet it does not prevent human error even when it is working as intended.

Analysis: The paradox here lies in the disconnect between a 'reliable' system and the persistence of human error. We are looking for a piece of information that explains why high-tech automation doesn't act as a fail-safe for the people operating it. An effective resolution might suggest that the technology actually creates new types of human errors, such as pilot complacency, or that the technology simply doesn't cover the specific areas where humans are most likely to fail. Focus on finding an answer that bridges the gap between mechanical reliability and human fallibility.
