Every time a plane crashes, the world takes notice. And so do the experts whose job it is to figure out what happened. Air Crash Investigations uncovers the truth behind the most legendary aviation disasters. Every episode features eyewitness accounts, captivating reenactments, state-of-the-art CGI, and interviews with the investigators who ultimately determined what went wrong. The twisted wreckage at the crash site tells part of the story; investigators can use it to learn about the final seconds of a flight and rule out mechanical failures. The flight data and cockpit voice recorders are critical, but they don't always reveal what happened. It almost always takes a tragic combination of factors to bring down an airplane. Unraveling the complex mystery is a painstaking process that takes months-and sometimes years-of detective work. From maintenance issues, dangerous cargo, and aircraft design, to extreme weather, pilot error, and even sabotage, investigators need to find the exact cause of every accident to ensure it never happens again. The air crash investigators owe it to the victims, the survivors, and their families to examine every clue and ultimately crack the case.
