3. The American Airlines Flight 965 near Cali, Colombia, while approaching the airport, the pilot intended to lock the autopilot onto the beacon, called Rozo, that would lead the plane to the airport. The pilot typed "R," and the computer system displayed six beacons beginning with "R." Normally, the closest beacon is at the top of the list. The pilot selected it without checking carefully.

In the dark, it crashed into a mountain, killing 159 people. Evaluating the incident, identify the reasons for failure of the system and what actions could prevent such incident to take place?
