Although commercial aviation remains one of the safest ways to travel, every accident is a stark reminder of the risks involved—and of how much can be learned from the moments when things go wrong.

This series revisits some of the world’s most infamous plane crashes, piecing together what happened through survivor testimony, expert interviews, investigation records and black-box data. From the first warning signs to the decisions made in the cockpit and on the ground, each episode traces how a chain of events unfolded—and why even small factors can have far-reaching consequences.

To explore what might have changed the outcome, a team of highly skilled test pilots recreates key scenarios using cutting-edge flight simulators. They examine the options available to the crew, test alternative responses and assess how training, technology and procedures might have helped. The aim is not simply to ask what went wrong, but to understand what could have been done differently—and how the lessons of the past can help make flying safer in the future.
