A high-tech turboprop struck by a million volts of lightning over the North Sea. A deadly maintenance error on one of the world's newest airliners. A midair explosion that nearly sucks a passenger from a window. Every plane accident comes with its own unique cause and its own unique outcome. And when these disasters strike, it's up to investigators to find out exactly what happened, and why. This season, we examine ten new air incidents, brought to life through witness accounts, interviews with experts, and dramatic reenactments.
