Following three horrifying crashes, investigators uncover fatal flaws in the very operations designed to prevent aircraft from plowing into mountains.

What was the catalyst for all three of these crashes?

From Season 3 Episode 5 "Mountains In The Way": Somehow flying in the wrong direction, a passenger jet crashes in the Himalayas. A Chinese airliner collides with a hillside just miles from a Korean airport. And, an Airbus crash in France reveals a deadly hightech blind spot.

On this special season of Air Crash Investigation, every episode examines multiple cases under a central theme: Heat of the Moment reveals the splitsecond decisions that resulted in tragedy; Take Off Missteps exposes how neglecting one critical step in a takeoff routine proved to be fatal; and, on Survivor Stories, passengers share their harrowing stories of survival after a major disaster.
