On 28 October 1492, Christopher Columbus landed on Cuba and confidently declared he had found Japan. He had not. His catastrophic geographical error set in motion events that would reshape the world, devastating Caribbean populations and launching centuries of colonial expansion. Meanwhile, on the same date in 2008, Volkswagen briefly became the world’s most valuable company after a short squeeze sent its share price soaring, a financial mishap that cost hedge funds billions. In 1993, Japan’s football team lost World Cup qualification in the final 90 seconds of their match in Doha, a moment still remembered as national heartbreak. And in 1971, Britain successfully launched its first and only domestically built satellite, Prospero, using a rocket programme the government had already cancelled. From navigational disasters to financial chaos, sporting tragedy to inadvertent space success, the 28th of October offers a masterclass in human overconfidence and the unpredictable consequences of getting things spectacularly wrong.

• Introduction Clara introduces the theme of geographical overconfidence through Columbus’s catastrophic navigational error, setting up a 28 October journey through history’s most confident mistakes.
• Columbus Calls Cuba Japan On 28 October 1492, Columbus lands on Cuba believing it to be Japan. His underestimation of Earth’s circumference, reliance on Marco Polo’s descriptions, and refusal to accept contrary evidence led to the colonial devastation of Caribbean indigenous populations and reshaped world history.
• Volkswagen’s Two-Day Reign On 28 October 2008, Porsche’s surprise announcement of controlling 74% of Volkswagen shares triggers a massive short squeeze. Volkswagen briefly becomes the world’s most valuable company as desperate hedge funds scramble to cover positions, losing billions in the process.
• The Agony of Doha On 28 October 1993, Japan’s national football team loses World Cup qualification when Iraq equalises in the 92nd minute. The devastating two-all draw, remembered as the Tragedy of Doha, denied Japan its first World Cup appearance and remains a cultural touchstone for heartbreak.
• Britain’s Cancelled Satellite Success On 28 October 1971, Britain launches Prospero, its first and only domestically built satellite, using the Black Arrow rocket. The programme had already been cancelled due to cost, making Britain’s successful entry to the space club both triumph and footnote.
• Conclusion Clara reflects on the day’s stories of confident mistakes, from navigation to finance to sport, noting that history consistently makes a strong case against human overconfidence.
