In 1954, the U.S. Navy commissioned USS Nautilus, the first nuclear-powered vessel in history, before anyone had proof the reactor would work at sea. This episode traces Admiral Hyman Rickover's fight to build her, the untested risk her volunteer crew accepted, and how one Connecticut shipyard helped launch an undersea arms race with the Soviet Union that still shapes nuclear strategy today.

On September 29, 2008, the House of Representatives rejected a $700 billion bank bailout, and the Dow Jones lost more value in a single day than it ever had before. Conservatives who feared government overreach and progressives who refused to rescue Wall Street cast the identical vote for opposite reasons, while the same government they'd just voted against was already propping up another failing bank on the very same day. This episode traces the ten days that led to that vote, the four days that reversed it, and the argument about who deserves rescuing that America still hasn't resolved.

The siege that ended the Revolutionary War is remembered as America's founding victory, but inside Cornwallis's lines at Yorktown were thousands of formerly enslaved people who had trusted a British promise of freedom with their lives. As food and medicine ran out, that promise collapsed, and the record shows the collapse was not an accident. This episode holds Cornwallis's tactical desperation, Washington's alliance-driven triumph, and a wartime betrayal that most retellings of Yorktown leave out.

On September 27, 1920, a washed-up prizefighter's confession forced open a year-long cover-up: eight Chicago White Sox players had conspired with gamblers to throw the 1919 World Series. This episode traces the underpaid players, the skimming gamblers, and the owner who buried his own investigation, then asks what changed now that the leagues sell the gambling instead of hiding it.

On September 26, 1983, a Soviet officer alone in a bunker outside Moscow had minutes to decide whether five blinking lights on a screen meant the end of the world. History remembers Stanislav Petrov as the man who saved it, but the fuller record includes a Soviet military embarrassed by its own machine, a hero quietly punished for paperwork, and a decision that still asks how much we should trust a system's confidence over our own judgment. This episode traces the night the Cold War nearly ended by sunlight.

On September 25, 1915, Britain used poison gas for the first time in the war it had condemned Germany for starting five months earlier at Ypres, only to watch the wind carry it back onto its own men at Loos. This episode follows the volunteers of Kitchener's New Army into that battle, including Rudyard Kipling's son John, and asks whether a moral line drawn against an enemy survives the moment it becomes inconvenient to keep.

On September 24, 1991, Geffen Records released Nirvana's Nevermind expecting a modest underground hit, and got the biggest miscalculation in the history of the record business instead. This episode traces how a record built on real scarcity became the object lesson for an entire industry's next decade of signing decisions, and what the sudden success cost the man who wrote it. It's a story about authenticity, commerce, and what happens when an industry tries to manufacture the thing that made a record work in the first place.

On September 23, 1779, John Paul Jones fought the British warship Serapis to a standstill off the English coast, in a battle now remembered mostly for four words he probably never said. The record shows a multinational crew, a rival American captain who fired on his own commander's ship, and a defeated British captain who was knighted anyway for saving the convoy he was protecting. This episode traces what happened during the Battle of Flamborough Head, and how the version everyone remembers came from a book written decades after the men who lived it were gone.

On September 22, 1975, Sara Jane Moore fired at President Gerald Ford outside San Francisco's St. Francis Hotel, and bystander Oliver Sipple's instinctive grab likely saved his life. This episode holds three competing realities at once: a discarded FBI informant chasing revolution, two law enforcement agencies that had the warning signs and missed them, and a reluctant hero whose outing to the press cost him his family and, eventually, his health.

On September 21, 1776, a fire tore through a quarter of British-occupied New York City the same night Continental Army spy Nathan Hale was caught trying to slip back across enemy lines. This episode weighs the case for Patriot sabotage against the summary executions British soldiers carried out on suspicion alone, and asks whether Hale's famous last words are history or embellishment. No side comes away with a clean verdict.
