THE BEAUMONT CHILDREN: AUSTRALIA'S MOST HAUNTING COLD CASE

Episode 125 | History's Mysteries — Mysterious Events In this Mystery episode we focus on the disappearance of Jane, Arnna, and Grant Beaumont — nine, seven, and four years old — who took a bus to Glenelg Beach in Adelaide on Australia Day 1966 and were never seen again, in a case that has been investigated for sixty years and remains completely unsolved. This episode covers what witnesses saw on the beach including the tall blond man seen with the children, the failed excavations of the New Castalloy factory site linked to suspect Harry Phipps, the ground-penetrating radar surveys still being conducted, and how the disappearance permanently changed Australian assumptions about childhood safety. Their mother Nancy died in 2019 at 92 years old. She never knew what happened to her children. #HistoryMystery #BeaumontChildren #ColdCase #Australia #MysteryPodcast

THE TITAN SUBMERSIBLE: THE WARNINGS NOBODY LISTENED TO

Episode 124 | Historical Events In this History episode we focus on the OceanGate Titan submersible implosion of June 2023 — the catastrophic failure of a carbon fiber deep-sea vessel carrying five people to the Titanic wreck, whose hull had been showing damage for eight dives before it imploded on its 88th, killing everyone aboard. This episode covers what a submersible is, why carbon fiber is the wrong material for repeated deep-sea pressure cycles, the engineers and marine professionals who warned OceanGate for years and were dismissed or fired, CEO Stockton Rush's public statements dismissing safety culture, and the Coast Guard's 2025 finding that if Rush had survived, the case would have been referred for potential manslaughter charges. The man dismissing the warnings was also on board. #HistoryMystery #TitanSubmersible #OceanGate #Titanic #HistoryPodcast

THE BLUE HOLE DAHAB: THE MOST DANGEROUS DIVE SITE IN THE WORLD

Episode 123 | History's Mysteries — Mysterious Events In this Mystery episode we focus on the Blue Hole near Dahab, Egypt — a natural sinkhole in the Red Sea reef where an underwater tunnel called the Arch sits at 55 meters depth, 15 meters below the safe limit for recreational air diving, and where over 200 divers have died attempting it. This episode covers what nitrogen narcosis does to a diver's judgment at depth, why the false chimney inside the Arch kills people who mistake it for the way out, the specific case of Yuri Lipski whose 2000 death was captured on camera and has been watched millions of times, and why experienced divers continue attempting the Arch despite knowing the statistics. At the entrance to the Blue Hole, on the rocky shore, there are memorial plaques. Dozens of them. The site is still dived almost every day. #HistoryMystery #BlueHoleDahab #CaveDiving #Diving #MysteryPodcast

ELISA LAM: THE ELEVATOR, THE WATER TANK, AND THE QUESTIONS THAT NEVER CLOSED

Episode 122 | History's Mysteries — Mysterious Events In this Mystery episode we focus on Elisa Lam — the 21-year-old Canadian student found dead in a rooftop water tank at the Cecil Hotel in Los Angeles in 2013, three weeks after she was last seen in elevator footage that went viral and has never been fully explained to everyone's satisfaction. This episode covers the Cecil Hotel's dark history, what the elevator footage actually shows and the official explanation for the door behavior, the roof access that was found unlocked, the coroner's ruling of accidental drowning consistent with a bipolar episode, and why the case remains officially closed while the questions remain publicly open. The case is officially closed. The questions are not. #HistoryMystery #ElisaLam #CecilHotel #TrueCrime #MysteryPodcast

MISSING 411: LINKING MISSING PERSONS AND US CAVE SYSTEMS

Episode 121 | History's Mysteries — Mysterious Events In this Mystery episode we focus on the Missing 411 phenomenon — the documented pattern of disappearances clustered near cave systems across the United States, catalogued by former police detective David Paulides, and what it does and doesn't tell us about 45,000 documented caves and the people who vanish near them. This episode covers specific cases including the 1969 disappearance of three-year-old Dennis Martin in the Great Smoky Mountains and the 2011 case of six-year-old Jaryd Atadero found years later at a higher elevation than he disappeared, the overlap between missing persons clusters and cave system maps, and the serious criticisms of the Missing 411 methodology — including selection bias and the fact that the National Park Service maintains no centralized public database of missing persons. The map looks the way it looks. Make of it what you will. #HistoryMystery #Missing411 #CaveDisappearances #UnsolvedMysteries #MysteryPodcast
