Causality

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.

In 2021 the Callide C Power Station experienced a unit failure that tore the turbine-generator apart, resulted in hundreds of thousands of premises losing power, and cost hundreds of millions to repair. We look at how design errors and ultimately a lack of information led to the incident escalating out of control, when it could have been recovered.

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. We look into how poor design checking and assumptions led to the bridge collapsing in 2007, costing the lives of 13 people.

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.

    A fireworks company in Western Australia that had been in business for nearly a century, were preparing for a fireworks display in their packing shed when one ignited and set off a fire and an explosion. Onlookers were shocked when there was a subsequent explosion that was so big it was heard 30 kilometers away leaving the facility in ruins.

    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. We look into how bureaucracy and misdiagnosis cost four people their lives and how the actions of a concerned mother with no medical experience, saved the lives of countless more.

    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. When two walkways collapsed killing over a hundred people, the investigators found multiple fundamental design errors. We look at how assumptions, redrafting conventions and negligence led to an incident that has become the case study in how not to do civil structural design.

    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.

It remains Australia's worst ever rail disaster that was predicted by 11 engineering department heads just a year earlier. We look at how management decisions led to a completely avoidable disaster.

    In Beirut in August of 2020, an explosion at the Port of Beirut destroyed a huge part of the city. We look into how an oxidising agent, improperly handled can become an explosive and attempt to comprehend how something so dangerous was ignored repeatedly by key people, despite many warnings of an imminent disaster.

    In 1911 in Manhattan, New York, a clothing factory went up in flames just before closing time. We look at how faulty equipment, poor design and a fear of theft contributed to a wholly preventable incident that had such terrible consequences, but would trigger reforms that still impact the United States, a century later.

    The original Royal Canberra Hospital was flagged to be demolished in 1997 to make way for the new National Museum. A demolition via implosion was selected, but the implosion resulted in an explosion instead, and debris showered the huge crowd of onlookers with fatal consequences.

    The successor to the Therac-6 and Therac-20 RadioTherapy machines would integrate the powerful DEC PDP-11 mini-computer to control all of the Therac-25s functions, including the safety interlocks, for the first time. In two years the 11 machines in service would overdose six people across two countries, killing three of them before they figured out why.

    A popular family-friendly ride at DreamWorld would claim the lives of four people in 2016. In nearly thirty years of operation the ride had several similar but non-fatal incidents with blame placed on the operator every time, when a three thousand dollar modification could have prevented a horrific incident.

    A series of concrete ceiling tiles in a tunnel portal collapsed on a moving car killing the passenger in downtown Boston in 2006. The selection of the epoxy used in the ceiling tile anchors was unusual and a failure to heed the warning signs were at odds on a huge project under pressure to deliver when already twice over time and five times over budget.

    One Friday morning in 1966 in a small town in Wales a mining spoils waste tip let go with a river of liquified rubble destroying buildings and a school. Killing 144 people, mostly children in their classrooms. The mechanics of how this happened are simple. The ignorance and economics of why this happened boggles the mind.
