The Vanishing Newspaper of 1690 and Other Curious Tales
The Vanishing Newspaper of 1690 and Other Curious Tales In today’s episode of The Daily Time Drop, host Clara Vale unravels the story of America’s first newspaper, ‘Publick Occurrences Both Forreign and Domestick’, which vanished almost as soon as it appeared in 1690 Boston. Clara explores why this bold venture by Benjamin Harris met with swift governmental opposition. From there, she transports listeners back to the Roman Empire of 275 AD, recounting the ill-fated reign of Marcus Claudius Tacitus, the last Roman emperor elected by the Senate. Finally, Clara brings us to 1974, where she explains how Tommy John surgery revolutionised both baseball and sports medicine. Join us for ten minutes of fascinating history, full of human ambition and illogical turns. Chapters Intro Introduction to today’s topics: a vanished newspaper, an unusual emperor, and a groundbreaking surgery. Publick Occurrences Both Forreign and Domestick The story of America’s first newspaper and its clash with colonial authorities.

The Salad Bar Bioterror Attack That Changed America
The Salad Bar Bioterror Attack That Changed America On 24 September 1984, members of the Rajneeshpuram commune in rural Oregon began deliberately contaminating salad bars in The Dalles with Salmonella bacteria. Over the following weeks, 751 people fell ill in what became the largest bioterrorist attack on American soil. The motive was chillingly simple: suppress voter turnout in a local election. The truth wouldn’t emerge for over a year, and only when the commune’s leadership fell apart from within. This episode explores how a religious commune’s power grab exposed fundamental vulnerabilities in public health systems and shaped modern understanding of bioterrorism. Also covered: Terry Herbert’s discovery of the Staffordshire Hoard in 2009, the largest Anglo-Saxon gold find in history; Henri Giffard’s pioneering steam-powered airship flight in 1852; and the rather unfortunate case of Japan Airlines Flight 472, which in 1972 managed to land at entirely the wrong airport in Bombay. Chapters Introduction A hook about bioterrorism, salad bars, and a religious commune in Oregon with unusual campaign tactics. The Rajneeshee Salad Bar Poisonings How members of the Rajneeshpuram commune contaminated restaurant salad bars in The Dalles, Oregon, sickening 751 people in an attempt to influence a local election. The attack went undetected as deliberate for over a year, until internal commune conflict led to confessions and FBI investigation. The Staffordshire Hoard Terry Herbert’s 2009 discovery of over five kilograms of Anglo-Saxon gold in a Staffordshire field. The hoard was officially declared treasure on 24 September 2009 and became the largest find of its kind in British history. Giffard’s Dirigible Henri Giffard’s successful flight of the first powered, steerable airship on 24 September 1852, travelling seventeen miles from Paris to Trappes at six miles per hour. Japan Airlines Flight 472 The 1972 incident in which a Japan Airlines flight landed at the wrong airport in Bombay, overrunning the shorter runway at Juhu Aerodrome and injuring eleven people. Outro Closing reflections on the day’s collection of human miscalculation, discovery, and ambition.

The Spacecraft Lost by a Spreadsheet Error, and Other Tales of Ambition
The Spacecraft Lost by a Spreadsheet Error, and Other Tales of Ambition On 23 September 1999, NASA lost contact with the Mars Climate Orbiter after a catastrophic navigation error caused by one team using imperial units and another using metric. The spacecraft, which cost $125 million and had travelled for nine months, burned up in the Martian atmosphere. This episode examines that expensive mistake alongside three other moments from the same date: the deification of Drusilla, sister of Roman Emperor Caligula, in 38 AD, making her the first Roman woman granted divine status; the fatal 1910 Alpine crossing by 23-year-old aviator Jorge Chávez, who became the first person to fly over the Alps in a Blériot XI monoplane before his aircraft collapsed on landing; and the 1884 grounding of the steamship Arctique near the Strait of Magellan, which accidentally triggered the Tierra del Fuego gold rush when survivors discovered gold deposits nearby. Each story reveals the often uncomfortable gap between human intention and historical outcome. Chapters Introduction Clara Vale introduces the episode’s theme: how do you lose a spacecraft? The answer involves mixing up metric and imperial units, costing NASA $125 million and a Mars mission. The Mars Climate Orbiter: A Hundred and Twenty-Five Million Reasons to Check Your Units The Mars Climate Orbiter launched in December 1998 and was lost on 23 September 1999 due to a navigation error. Lockheed Martin sent thruster data in pound-force seconds whilst NASA’s Jet Propulsion Laboratory expected newton seconds, causing the spacecraft to enter Mars’ atmosphere at the wrong angle and disappear. Caligula Makes His Sister a Goddess On 23 September 38 AD, Roman Emperor Caligula deified his sister Drusilla as Panthea following her death in June. She became the first Roman woman granted divine status, though this did not survive Caligula’s assassination in 41 AD. Jorge Chávez Crosses the Alps On 23 September 1910, 23-year-old aviator Jorge Chávez became the first person to fly across the Alps, crossing from Brig, Switzerland to Domodossola, Italy in a Blériot XI monoplane. His aircraft’s wings collapsed on landing and he died four days later from his injuries. The Arctique Runs Aground and Starts a Gold Rush The steamship Arctique ran aground near Cape Virgenes on 23 September 1884. Survivors discovered placer gold nearby, triggering the Tierra del Fuego gold rush and accelerating colonisation of the region, with devastating consequences for the indigenous Selknam people. Outro Clara reflects on the gap between human intention and historical outcome, connecting the day’s stories of ambition, planning, and unexpected consequences.

The Five Thousand Percent Man and the Cabinet Duel
The Five Thousand Percent Man and the Cabinet Duel On 21 September 2015, the price of a life-saving drug called Daraprim rose from $13.50 to $750 per tablet overnight, a 5,455% increase that sparked global outrage and forced a national conversation about pharmaceutical pricing. Clare Vale unpacks Martin Shkreli’s infamous decision and its human cost, then steps back to 1809, when two serving British Cabinet ministers resolved a political dispute with pistols on Putney Heath. The episode also visits the 2018 legislative elections in Eswatini, where political parties remain banned by royal decree, and closes with the 1983 FCC approval of the Motorola DynaTAC 8000X, the world’s first commercially available mobile phone. Four stories about power, pricing, politics, and the devices that quietly changed everything. Chapters Intro Clare introduces the 5,455% overnight price rise of a life-saving drug and the man who seemed confused by the backlash. The Five Thousand Percent Man Martin Shkreli’s Turing Pharmaceuticals raised the price of Daraprim from $13.50 to $750 per tablet on 21 September 2015, causing immediate harm to patients and igniting a national debate about drug pricing in America. Two Cabinet Ministers and a Pistol on Putney Heath On 21 September 1809, British Foreign Secretary George Canning and War Secretary Viscount Castlereagh fought a duel on Putney Heath over a Cabinet dispute. Both resigned. Both went on to distinguished careers. An Election With No Parties Eswatini held legislative elections on 21 September 2018 under a system that has banned political parties since 1973, with all candidates standing as independents in an absolute monarchy. The Eight Hundred Gram Future The FCC approved the Motorola DynaTAC 8000X on 21 September 1983, making it the first commercially available handheld mobile phone. It weighed 800 grams, cost nearly $4,000, and quietly began a revolution. Outro Clare reflects on how small moments and strange decisions carry enormous consequences, often only visible in hindsight.

A Tsunami, a Rocket, and Three Thousand People Who Nearly Stormed Area 51
A Tsunami, a Rocket, and Three Thousand People Who Nearly Stormed Area 51 On 20 September 1498, the Nankai earthquake sent a tsunami crashing into coastal Japan, destroying the wooden hall around the Great Buddha of Kōtoku-in. The forty-foot bronze statue survived, and for over five centuries has sat in the open air without a roof. Five hundred and two years later, on the same date in 2000, someone fired a Russian-built RPG-22 anti-tank missile at the MI6 building in London. The headquarters sustained damage but no casualties, and the attack remains unsolved. Then, in 2019, thousands gathered near Area 51 in Nevada after a viral Facebook event proposed storming the classified US military facility to find aliens. Nobody stormed anything. They had a party instead. Three moments in history: one serene, one alarming, one absurd. All taking place on the same calendar date, centuries apart. Clara Vale explores the earthquake that reshaped a coastline, the rocket that struck a spy headquarters, and the internet event that became a desert festival. Chapters Introduction Clara introduces three events from the twentieth of September: a tsunami in medieval Japan, a rocket attack on MI6, and a crowd gathering near Area 51. The Nankai Tsunami and the Great Buddha of Kōtoku-in On 20 September 1498, the Nankai earthquake and tsunami destroyed the wooden hall around the Great Buddha statue at Kōtoku-in temple in Japan. The forty-foot bronze figure survived and has sat outdoors ever since, enduring five centuries of weather and seismic activity. The MI6 Rocket Attack At midnight on 20 September 2000, a Russian-built RPG-22 anti-tank missile was fired at the MI6 headquarters in London, striking the eighth floor. The building sustained damage but no injuries, and the attack remains unsolved. Storm Area 51 On 20 September 2019, thousands gathered near Area 51 in Nevada after a viral Facebook event proposed storming the classified US military facility. Despite two million online RSVPs, attendees held festivals rather than trespassing, and the day ended peacefully. Outro Clara reflects on the contrast between the three stories: a catastrophe that revealed endurance, an attack on a spy headquarters, and an internet joke that became a wholesome gathering.

Trollface, Ötzi's Murder, and the Day Mexico's Earthquake Drill Became Real
Trollface, Ötzi’s Murder, and the Day Mexico’s Earthquake Drill Became Real On 19 September 2008, an 18-year-old student in Oakland uploaded a deliberately crude drawing that became one of the internet’s most recognisable images. Trollface, created by Carlos Ramírez in Microsoft Paint, evolved from a joke comic about online provocation into a copyrighted icon that earned its creator hundreds of thousands of dollars. But the 19th of September holds darker stories too. In 1991, hikers in the Ötztal Alps discovered a 5,300-year-old murder victim, the oldest known homicide case in history. The body, now known as Ötzi the Iceman, revealed extraordinary details about Copper Age life and a violent death from an arrow wound. Mexico’s relationship with this date is particularly haunting. After the devastating 1985 earthquake, the country instituted annual drills on 19 September. In 2017 and again in 2022, real earthquakes struck during those commemorative drills, an eerie statistical coincidence that reshaped how Mexicans understand disaster preparedness. Finally, in 1980, a dropped socket wrench at a Titan missile silo in Arkansas led to a fuel leak, an explosion, and a nuclear warhead thrown into a ditch, a near-catastrophe triggered by an eight-pound tool. Four very different stories, one date, and proof that history keeps excellent notes on human overconfidence. Chapters Introduction Clara introduces the episode with a teaser about a deliberately bad drawing that became an internet icon, setting the stage for stories from 19 September across different years and contexts. Trollface: The Face That Trolled the World On 19 September 2008, Carlos Ramírez uploaded Trollface, a crude drawing that became a defining image of early internet culture. Created in Microsoft Paint to satirise 4chan trolling behaviour, the image spread through rage comics and became a copyrighted asset earning its creator hundreds of thousands of dollars. Ötzi the Iceman: A Very Cold Case On 19 September 1991, hikers in the Ötztal Alps discovered a 5,300-year-old body preserved in ice. Ötzi, as he became known, was a Copper Age murder victim with an arrowhead in his shoulder, 61 tattoos, and equipment revealing sophisticated knowledge. He remains the most studied human in scientific history. Mexico’s Earthquakes and the Drill That Wasn’t a Drill After the catastrophic 1985 earthquake, Mexico instituted annual drills on 19 September. In both 2017 and 2022, real earthquakes struck during these commemorative drills, an extraordinary statistical coincidence that reinforced the importance of disaster preparedness in Mexican public life. The Titan Missile Explosion in Arkansas On 18-19 September 1980, a dropped socket wrench punctured the fuel tank of a Titan II intercontinental ballistic missile in Arkansas. The resulting explosion killed one person, threw a multi-megaton nuclear warhead into a ditch, and contributed to the retirement of the Titan II programme. Conclusion Clara reflects on the diverse stories of 19 September, from internet culture to ancient murder, disaster preparedness to nuclear near-misses, concluding with her characteristic observation about human overconfidence throughout history.

Philippe Croizon Swims the Channel, Exploding Walkie-Talkies, and the Return of the Zeppelin
Philippe Croizon Swims the Channel, Exploding Walkie-Talkies, and the Return of the Zeppelin On 18 September 2010, Philippe Croizon became the first quadruple amputee to swim the English Channel, completing the crossing in thirteen hours and twenty-six minutes using prosthetic fins and core propulsion. The same date in 2024 saw coordinated attacks in Lebanon when modified walkie-talkies used by Hezbollah exploded, killing fourteen people and wounding hundreds in what appeared to be a sophisticated intelligence operation. In 2017, Toys R Us filed for bankruptcy protection in the United States and Canada, ending decades as a defining retail experience for children, undone by five billion dollars in debt from a 2005 leveraged buyout. And in 1997, the first Zeppelin NT took its maiden flight over Lake Constance in Germany, marking the return of rigid airship technology sixty years after the Hindenburg disaster ended the original Zeppelin era. Four stories from one date: human determination, modern warfare, corporate collapse, and quiet resurrection. Chapters Intro Clara introduces the episode by setting the scene of the English Channel and the seemingly impossible feat that Philippe Croizon accomplished on this date in 2010. Philippe Croizon Swims the English Channel In 2010, Philippe Croizon became the first quadruple amputee to swim the English Channel. After losing all four limbs in a 1994 electrical accident, he spent years in depression before training with prosthetic fins. He completed the crossing in thirteen hours and twenty-six minutes, later going on to swim straits between four continents in 2012. Hezbollah Walkie-Talkie Explosions, Lebanon On 18 September 2024, walkie-talkie devices used by Hezbollah exploded across Lebanon, killing fourteen and wounding four hundred and fifty. The devices had apparently been intercepted and modified before delivery, turning communication tools into weapons in a sophisticated intelligence operation widely attributed to Israel. Toys R Us Files for Bankruptcy In 2017, Toys R Us filed for bankruptcy protection, carrying five billion dollars in debt from a 2005 leveraged buyout. The retail giant that had defined childhood shopping for decades closed its last US stores in 2018, unable to compete with online retail or invest in necessary transformation. The Return of the Zeppelin In 1997, the first Zeppelin NT took its maiden flight over Lake Constance in Germany, marking the return of rigid airship technology sixty years after the Hindenburg disaster. The new helium-filled, semi-rigid airship flew in the same region where Count Ferdinand von Zeppelin first tested his invention at the start of the twentieth century. Outro Clara reflects on the stories of 18 September, focusing on Philippe Croizon’s quiet determination and the years of training before anyone was watching.

The Man Who Found the Invisible World
The Man Who Found the Invisible World On 17 September 1683, Antonie van Leeuwenhoek wrote to the Royal Society describing what he had observed in scrapings from human teeth: tiny creatures, moving with apparent purpose, completely invisible to the naked eye. The Dutch draper, who ground his own lenses and built microscopes capable of magnifications up to 270 times, had become the first person in history to observe bacteria and oral microorganisms. With no university education and no institutional backing, Leeuwenhoek revealed an entire world that had existed alongside humanity for all of recorded history, yet remained utterly unknown. Also on this day: in 2022, eight cheetahs arrived at Kuno National Park in India, ending a 75-year absence of the species from the subcontinent. In 2006, a leaked audio recording brought down the Hungarian prime minister’s credibility when Ferenc Gyurcsány was heard admitting his party had lied throughout their election campaign. And that same year, Fourpeaked Mountain in Alaska erupted for the first time in at least 10,000 years, forcing geologists to reclassify what they had assumed was a dormant volcano. Chapters Intro Clara introduces the episode’s central question: what if an entire invisible world had existed alongside humanity all along, completely unknown until someone bothered to look closely enough? The Man Who Found the Invisible World On 17 September 1683, Antonie van Leeuwenhoek wrote to the Royal Society describing his observation of bacteria and protozoa in human mouth scrapings. The self-taught Dutch draper had built microscopes achieving magnifications of up to 270 times, revealing microorganisms no one had ever seen before. His careful observations laid the groundwork for modern microbiology, two centuries before germ theory would fully emerge. Cheetahs Return to India On 17 September 2022, eight cheetahs from Namibia arrived at Kuno National Park in Madhya Pradesh, marking the first time the species had stood on Indian soil since 1947. The reintroduction programme aimed to restore an animal that had lived in India for thousands of years before being hunted to local extinction. The Speech That Wasn’t Meant for Everyone On 17 September 2006, a leaked audio recording revealed Hungarian Prime Minister Ferenc Gyurcsány admitting to his own party that they had lied consistently about the economy during their election campaign. The confession sparked widespread protests and lasting damage to public trust. The Volcano That Waited Ten Thousand Years Also on 17 September 2006, Fourpeaked Mountain in Alaska erupted for the first time in at least 10,000 years. The volcano had been classified as dormant, forcing geologists to reassess and reclassify it as active, a reminder that geological timescales operate independently of human categories. Outro Clara reflects on Leeuwenhoek’s legacy: a man who made his own tools, asked his own questions, and fundamentally changed humanity’s understanding of life on Earth, driven purely by curiosity that would not let him stop looking.

The Balloon Escape Over the Iron Curtain and a Pope Excommunicated After Death
The Balloon Escape Over the Iron Curtain and a Pope Excommunicated After Death On 16 September 1979, two East German families flew a homemade hot air balloon over the Iron Curtain in one of the Cold War’s most audacious escapes. The Strelzyks and Wetzels, ordinary citizens from Pössneck, built a 28-metre balloon from taffeta and cotton bought in secret, then flew eight people, including four children, across the heavily militarised border in 28 minutes of flight. They landed in Bavaria, free. Also on this date in 681, the Sixth Ecumenical Council excommunicated Pope Honorius I, 42 years after his death, for letters that seemed to support the Monothelite heresy. The posthumous condemnation fuelled debates about papal authority for over a millennium. And in 1732, a lightning strike hit the armoury in Campo Maior, Portugal, causing an explosion that killed roughly 800 people, two-thirds of the town’s population. The town was rebuilt and today hosts the vibrant Festa do Povo flower festival. Three stories about walls, literal and theological, and what people do when faced with them. Chapters Intro Clara introduces the seemingly impossible question: how do you escape one of the most militarised borders in modern history? Two East German families answered by building a hot air balloon in secret. The Great Balloon Escape of 1979 On 16 September 1979, the Strelzyk and Wetzel families flew a homemade hot air balloon over the Iron Curtain. After a failed first attempt in 1978, they built a 28-metre envelope from fabric bought in secret, sewed it at home, and launched with eight people on board. After 28 minutes in the air, they landed in Bavaria, having crossed one of the world’s most lethal borders. The Stasi were reportedly furious. The escape became a Disney film in 1982. The Pope Who Was Excommunicated After He Died On 16 September 681, the Sixth Ecumenical Council excommunicated Pope Honorius I, who had died 42 years earlier. His letters during the Monothelite controversy were deemed too sympathetic to heresy. The posthumous condemnation became a key historical problem in debates about papal infallibility, unresolved until the First Vatican Council in 1870. The Campo Maior Catastrophe of 1732 On 16 September 1732, lightning struck the armoury in Campo Maior, Portugal, igniting stored gunpowder. The explosion killed around 800 people, roughly two-thirds of the town’s population. Campo Maior was rebuilt and today hosts the Festa do Povo, a flower festival that fills the streets with colour. Outro Clara closes with reflections on walls, literal and otherwise, and what people do when faced with them. She signs off with her usual dry amusement about human overconfidence.

The Locomotive That Outlasted Everything and a Spacecraft's Final Dive
The Locomotive That Outlasted Everything and a Spacecraft’s Final Dive On 15 September 1981, the John Bull, a steam locomotive built in 1831, ran under its own power outside Washington DC, making it the oldest operable steam locomotive in the world. One hundred and fifty years after its construction, it proved that some engineering simply refuses to be retired. We also look at the 1813 attack on Beijing’s Forbidden City by the Eight Trigram Sect, a religious uprising that briefly breached the walls of imperial power. In 1994, Swiss astronomer Didier Queloz detected the wobble that would confirm the first exoplanet orbiting a sun-like star, forcing scientists to rethink how solar systems form. And on this date in 2017, NASA’s Cassini spacecraft completed its thirteen-year mission by diving into Saturn’s atmosphere, transmitting data until the very last second. Four stories about persistence, vulnerability, discovery, and knowing when to bow out gracefully. Chapters Introduction Clara introduces the episode’s theme of things that refuse to quit, setting up four stories from 15 September across different centuries. The John Bull: Still Running After 150 Years The 1831 steam locomotive John Bull ran under its own power in 1981, 150 years after construction, becoming the oldest operable steam locomotive in the world. Built by Robert Stephenson’s firm and shipped to New Jersey, it served the Camden and Amboy Railroad before retirement in 1866 and eventual donation to the Smithsonian. The Attack on the Forbidden City, 1813 On 15 September 1813, followers of the Eight Trigram Sect stormed the Forbidden City in Beijing whilst the Jiaqing Emperor was away hunting. With help from palace eunuchs, they breached the walls before being suppressed, revealing cracks in Qing dynasty power that would eventually lead to its collapse. The First Exoplanet, 1994 Swiss doctoral student Didier Queloz detected a wobble in the star 51 Pegasi in 1994, confirming the first exoplanet orbiting a sun-like star. The gas giant, orbiting closer than Mercury to our sun, forced a complete rethink of planetary formation models. Queloz shared the 2019 Nobel Prize in Physics for the discovery. Cassini’s Final Dive, 2017 On 15 September 2017, NASA’s Cassini spacecraft ended its thirteen-year Saturn mission by diving into the planet’s atmosphere. Launched in 1997, Cassini discovered evidence of subsurface oceans on Enceladus, dropped the Huygens probe on Titan, and transmitted atmospheric data until its signal stopped. Closing Thoughts Clara reflects on the day’s stories of persistence, discovery, and graceful endings, closing with her trademark observation about human overconfidence.

Gravitational Waves, Black Holes, and the Day Britain Lost Eleven Days
Gravitational Waves, Black Holes, and the Day Britain Lost Eleven Days On 14 September 2015, the LIGO detectors in Louisiana and Washington State captured the first direct observation of gravitational waves, ripples in space-time predicted by Einstein a century earlier. The signal came from two black holes colliding 1.3 billion light-years away, their merger converting three solar masses into pure energy. The detection confirmed General Relativity, opened gravitational wave astronomy, and earned its discoverers the 2017 Nobel Prize in Physics. Meanwhile, 14 September 1752 marked Britain’s chaotic adoption of the Gregorian calendar after 170 years of resistance. To realign with Europe, Parliament skipped eleven days: 2 September was followed directly by 14 September. Though popular legend claims riots erupted over the missing days, historians remain sceptical. The administrative confusion, however, was real, as rents, contracts, and schedules had to recalibrate overnight. Two stories about timing: one signal that travelled for over a billion years, and eleven days that simply vanished. Chapters Intro Clara opens by asking what the universe actually sounds like, introducing the 14 September 2015 detection of gravitational waves by LIGO, a signal that had travelled 1.3 billion years and sounded like a chirp. The Chirp Heard Across a Billion Years On 14 September 2015, LIGO’s Louisiana and Washington State detectors captured a gravitational wave signal from two colliding black holes 1.3 billion light-years away. The detection, announced in February 2016, confirmed Einstein’s 1916 prediction, earned the 2017 Nobel Prize, and opened the field of gravitational wave astronomy. Britain Loses Eleven Days On 14 September 1752, Britain adopted the Gregorian calendar, skipping eleven days to realign with Europe after 170 years of resistance. The Calendar Act caused administrative confusion, though popular stories of riots demanding the days back are historically disputed. Outro Clara reflects on history’s sense of timing: a signal that travelled for over a billion years, and eleven days that simply disappeared from the calendar.

The Glowing Scrap: When a Forgotten Radiotherapy Machine Contaminated a City
The Glowing Scrap: When a Forgotten Radiotherapy Machine Contaminated a City On 13 September 1987, two scavengers in Goiânia, Brazil broke into an abandoned radiotherapy clinic and stole a teletherapy machine containing caesium-137. They did not know what it was. They only knew it looked valuable. Over the following days, the ruptured radioactive capsule spread contamination across multiple households. The powder inside glowed blue in the dark, and people, fascinated, gathered to see it. A six-year-old girl ate a sandwich after touching it. Within weeks, four people were dead and 249 were contaminated in one of the worst radiological accidents in history. The disaster exposed systemic regulatory failures around medical radioactive sources and changed international protocols on the disposal of such equipment. Also remembered today: the mysterious 1971 death of Lin Biao, Mao’s designated successor, in a plane crash over Mongolia following an alleged coup attempt, and the 1807 premiere of Beethoven’s Mass in C major, which Prince Esterházy disliked so intensely that Beethoven left early and never received another commission from him. Chapters Intro Clara introduces a disaster that arrived quietly, with no visible flames or explosions, just an invisible threat doing damage so slowly that by the time anyone realised, it was too late. The Glowing Scrap: The Goiânia Radioactive Disaster, 1987 On 13 September 1987, two scavengers stole an abandoned radiotherapy machine from a closed clinic in Goiânia, Brazil. The caesium-137 capsule inside was ruptured, releasing glowing blue powder that fascinated locals. A six-year-old girl died after touching it. Four people died in total, 249 were contaminated, and the cleanup required demolishing seven houses. The accident exposed catastrophic regulatory failures and changed international protocols on medical radioactive sources. Luna 2 and the Long Fall of Lin Biao, 1971 On 13 September 1971, Lin Biao, Mao Zedong’s designated successor, died when his plane crashed in Mongolia. The Chinese government claimed he was fleeing after a failed coup attempt. The full details remain disputed, but Lin was posthumously expelled from the Communist Party and denounced as a traitor. Beethoven Gets a Cold Reception, 1807 On 13 September 1807, Beethoven’s Mass in C major premiered for Prince Nikolaus Esterházy, who disliked it so intensely that Beethoven left early. The Prince had expected something like Haydn. He got Beethoven instead. History has taken Beethoven’s side. Outro Clara reflects that history is rarely about grand forces working predictably. It is about a capsule left in a room, a succession plan ending in a field, and a prince expecting one composer and getting another.

Nepal's Discord Democracy, the Faroe Islands' Football Miracle, and a Spacecraft Chasing a Potato
Nepal’s Discord Democracy, the Faroe Islands’ Football Miracle, and a Spacecraft Chasing a Potato On 12 September across recent decades, history delivered an improbable collection of human moments. In 2025, Nepal elected interim Prime Minister Sushila Karki through a parliamentary vote held on Discord, the gaming chat platform. In 1990, the Faroe Islands, a nation of 47,000 with a fisherman in goal, defeated Austria 1-0 in their first competitive international football match. In 1994, Frank Corder flew a stolen Cessna into the White House lawn whilst President Clinton was staying elsewhere, triggering a major security reassessment. And in 2005, Japan’s Hayabusa spacecraft arrived at asteroid Itokawa after two years of travel, eventually returning samples that changed our understanding of rubble pile asteroids. From digital democracy in the Himalayas to deep space sample collection, this episode explores how the improbable becomes historical fact, and how humans continue to surprise themselves with what they can achieve, even when the method involves a Discord server or a potato-shaped rock 300 million kilometres away. Chapters Introduction Clare opens with the extraordinary image of Nepal conducting a parliamentary vote through Discord in 2025, setting the tone for a collection of improbable historical moments all occurring on 12 September. Discord Democracy: Nepal Elects a Prime Minister Online In 2025, Nepal elected former Supreme Court Chief Justice Sushila Karki as interim Prime Minister through a parliamentary vote held on Discord, the gaming chat platform, demonstrating both pragmatic adaptation and the strange infrastructure of modern governance. The Faroe Islands’ Greatest Miracle: Beating Austria in 1990 On their competitive international debut, the Faroe Islands, population 47,000 with a fisherman goalkeeper, defeated Austria 1-0 in a European Championship qualifier, creating one of football’s most extraordinary upsets. Frank Corder and the Plane on the Lawn: 1994 Frank Corder flew a stolen Cessna into the White House south lawn in the early hours whilst President Clinton stayed elsewhere during renovations, an event that fundamentally changed White House security protocols. Hayabusa Meets an Asteroid: 2005 Japan’s Hayabusa spacecraft arrived at asteroid Itokawa after two years of travel, eventually returning samples to Earth in 2010 that revealed it to be a rubble pile asteroid and advanced planetary defence research. Closing Thoughts Clare reflects on the diverse ways history manifests on a single date, from digital democracy to deep space exploration, and how humans continue to make improbable things happen.

Chess in the Clouds, Rogue Waves, and a Song Called The Great Fire
Chess in the Clouds, Rogue Waves, and a Song Called The Great Fire On 11 September 1995, two of the world’s greatest chess players faced each other on the 107th floor of the World Trade Center’s South Tower. Garry Kasparov defended his world title against Viswanathan Anand in a match that announced a new era of the game, staged in a location that would, six years later, carry an entirely different meaning. That same day, the RMS Queen Elizabeth 2 encountered a massive rogue wave in the North Atlantic, an event that helped overturn centuries of scientific scepticism about freak waves and vindicated generations of dismissed sailor testimony. Years later, on 11 September 2001, French rock band Noir Désir released an album featuring a song called The Great Fire on the morning the Twin Towers fell. Three events, one date, and the strange way history layers meaning onto the calendar without asking permission. Clara Vale explores coincidence, tragedy, and the moments when human ambition meets the unpredictable forces of the world. Chapters Intro Setting the scene for a world championship chess match played on the 107th floor of the World Trade Center in 1995. The Chess Match at the Top of the World Garry Kasparov defends his world title against Viswanathan Anand in a PCA world championship match held high above Manhattan on 11 September 1995, in a location that history would later redefine. The Wave That Changed Science The RMS Queen Elizabeth 2 encounters a rogue wave in the North Atlantic on the same day, an incident that helped shift scientific consensus on freak waves and validated centuries of sailor testimony. Noir Désir and the Darkest Morning French rock band Noir Désir releases an album containing a song called The Great Fire on the morning of 11 September 2001, a coincidence of timing that carries haunting weight. Outro Reflecting on how history layers multiple meanings onto a single date, from chess matches to ocean science to tragedy.
