⚡️ Mindbender

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.With John Chidgey.This show is Podcasting 2.0 EnhancedLinks of Interest:MindbenderGeoffrey KulakMindbender (Galaxyland)Triple Five GroupRoller coaster wheel assembly BogieSchwarzkopf GmbH6 Reasons Why Bolts Fail & How To Prevent...

⚡️ Granville

In 1977, a commuter train from the Blue Mountains, destined for Sydney central station would derail just before Granville Station, causing a bridge to collapse and crush many aboard. 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.With John Chidgey.This show is Podcasting 2.0 EnhancedLinks of Interest:Granville rail disasterThe Day of the RosesPublic Transport Commission of NSWGranville Train DisasterTurnoutsCityRailAustralia’s worst rail disasterThe Granville Train Disaster AssociationRevisiting the Granville Train Disaster of...

⚡️ Beirut Warehouse 12

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.With John Chidgey.This show is Podcasting 2.0 EnhancedLinks of Interest:2020 Beirut ExplosionCondensation CloudPrillANFOAmmonium NitrateHow an unscheduled port visit led to disasterBeirut Ammonium Nitrate BlastGovernment Amends Ammonium Nitrate RulesFBI probe shows amount of chemicals in Beirut blast was a fraction of...

⚡️ Triangle Shirtwaist Factory

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.With John Chidgey.This show is Podcasting 2.0 EnhancedLinks of Interest:Triangle Shirtwaist Factory FireBrown BuildingShirtwaistCourt Transcript of the Criminal TrialThe Triangle Fire of 1911Sweatshop TragedyBrown Building (PDF)Sweatshop DefinitionMachinery Needed for Garment ManufacturingDifferent Types of Sewing Line LayoutWorld Tallest Building...

⚡️ Royal Canberra Hospital

The original Royal Canberra Hospital was flagged to be demolished in 1997 to make way for the new National Museum.

⚡️ Florida International University

The university wanted a bridge for its students over a busy roadway that would appear intriguing from afar. Instead it collapsed before it was even finished.

⚡️ Ocean Ranger

The largest semi-submersible Offshore Drilling Rig of its day, sank in a storm in 1982 whilst two smaller nearby rigs survived with minimal damage. We dive into how not closing a portlight cover, triggered a series of events that cost 84 people their lives.With John Chidgey.This show is Podcasting 2.0 EnhancedReport into the Incidents:Official ReportLinks of Potential Interest:Ocean RangerHydrodynamic Model Studies of the Ocean Ranger Marine DisasterThe Loss of the Ocean RangerRoyal CommissionOcean Ranger report blames equipment and trainingHypothermia TableHistory of offshore drilling unitsGlossary of nautical termsRoustaboutDavit25 years later

⚡️ Therac-25

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.With John Chidgey.This show is Podcasting 2.0 EnhancedReports into the Incidents:An Investigation of the Therac-25 Accidents‎Medical Devices: The Therac-25The Therac-25: 30 Years LaterA Usage-Model Based Approach to Test Therac-25Good Computing: A Virtue Approach To Computer Et...

⚡️ Thunder River Rapids

A popular family-friendly ride at DreamWorld would claim the lives of four people in 2016.

⚡️ Big Dig

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.With John Chidgey.Investigation Report:NTSB Report (PDF)Technical Links:EpoxyTunnelLinks of Potential Interest:Big Dig ceiling collapseCollapse of Big Dig Ceiling in Boston Is Tied to...
