Causality

Chain of Events. Cause and Effect. We analyse what went right and what went wrong as we discover that many outcomes can be predicted, planned for and even prevented.

61: West Gate Bridge

November 29, 2025 • 38 mins
Planned for nearly a century, when the time came to build a permanent link across the Lower Yarra River, a relatively new style of bridge, the box-girder, was chosen. Using new computer technology assisting the engineers to design a bridge that was too complex to calculate by hand, and using a unique lifting strategy promised time and cost savings. Ultimately though when the pieces didn't fit together in the air, their attempts...

August 26, 2025 • 24 mins
A leaking flexible pipe started a fire in the Engine Room aboard the Carnival Triumph during its return journey from Mexico in early 2013.

After an extended outage of the Methomyl Unit at the Bayer facility in Institute, West Virginia, the decision was made to commence a restart of the Unit even though the DCS upgrade was still incomplete and the newly replaced Residue Treater hadn't been fully recommissioned. An incident whose root cause was years in the making would ultimately cost two people their lives.

June 25, 2024 • 28 mins
In 2017 during an Odoriser decontamination procedure in West Virginia, two people were killed when it unexpectedly exploded. Barely a month later, a similar procedure at the same site led to a second explosion, killing someone else. We examine how poor hazard analysis and legal interference led to yet another fatality...right in front of the eyes of the investigators on site.

51: I35 West

August 27, 2023 • 36 mins
The I35W bridge over the Mississippi River carried 140,000 cars every day. Inspections in 1999 and 2003 showed damage to support plates that was dismissed as unimportant at the time.

50: 737 MAX Ethiopian Air

April 22, 2023 • 52 mins
Five months after Lion Air 610 crashed, another 737-MAX went down with a similar cause. However the official report was at odds with two other internationally respected investigative organisations. We dig into the detail of how the AOA Sensor was claimed to have failed, and review checklist discrepancies to extract fact from opinion as to what most likely triggered this horrible chain of events.

    When a radiation therapy machine was left behind during a move between buildings in central Brazil, it set in motion a series of events that would lead to one of the worst radiological incidents in history.

    The tallest building in Missouri with a large atrium perfect for big bands and dancing, hosted a regular Tea Dance in the summer of 1981.

    The longest, tallest, fastest indoor rollercoaster in the world was only open six months when the last carriage of a train came loose, killing three people and all that the day following an inspection that the ride was safe to operate. We look at how a design choice made maintenance more critical and then how wishing for a ride to be safe, doesn't really help.

    In Beirut in August of 2020, an explosion at the Port of Beirut destroyed a huge part of the city.

    In 1911 in Manhattan, New York, a clothing factory went up in flames just before closing time.
