Special Report: Trained to Fail

Overview

Three flights suffer catastrophic computer errors that force investigators to dig deep for clues. A seasoned Alitalia crew somehow flies a DC-9 into the ground just miles from a Zurich runway. En route from Singapore to Perth, Qantas Flight 72 suddenly nosedives toward the Indian Ocean. And, without a key instrument to guide them, the pilots of a Venezuelan turboprop crash into a mountainside.
