The phaseout of leaded petrol is one of the quietest public health victories in history, yet the UN Environment Programme estimated it would prevent over 1.2 million premature deaths annually. The fact that it took nearly a century to stop is the part worth sitting with.
The first of September 2021 passed without much ceremony. Somewhere in Algeria, a driver pulled into a petrol station, filled their tank, and drove away. The most ordinary transaction in the world, except that it was the last time anyone on Earth purchased leaded petrol. One hundred years of quietly poisoning the planet, ended at an unremarkable pump.
The Slow Poison We Finally Stopped
Leaded petrol arrived in the 1920s as an antiknock agent, despite the dangers of lead being rather well understood. Geochemist Clair Patterson spent years documenting global lead contamination and faced considerable opposition from the industry profiting from selling the stuff. He was right, of course. They were better resourced.
The UN Environment Programme eventually drove the global phaseout to its conclusion. Their estimate of what eliminating leaded fuel achieves: over 1.2 million premature deaths prevented every year, and measurable reversal of damage to cognitive development at population scale. That second part deserves a moment. We were making ourselves, as a species, measurably less intelligent. And then we stopped.
New York to London in Under Two Hours
On the same date in 1974, the SR-71 Blackbird flew from New York to London in one hour, 54 minutes, and 56.4 seconds. It flew above 24 kilometres at over 1,400 miles per hour, exceeding Mach 3. The Cold War reconnaissance aircraft still holds that transatlantic record. More than 50 years later, nothing has beaten it.
The Court That Did Not Wait for the Ransom
On 1 September 1449, the Zhengtong Emperor of China was captured by Oirat Mongol forces at the fortress of Tumu. The Ming court’s response was swift and, frankly, a little cold: they appointed his younger brother as the Jingtai Emperor and carried on governing. The Zhengtong Emperor was eventually released and reclaimed the throne in a coup in 1457. Patient, if nothing else.
The Airship That Left Behind a Holiday Resort
CargoLifter AG was founded in Berlin on this date in 1996, with plans to build a 260-metre cargo airship capable of lifting 160 tonnes. They constructed one of the world’s largest free-standing halls at a former Soviet airbase. The airship never flew. The company filed for insolvency in 2002. The hangar is now Tropical Islands, an indoor resort with an actual beach. Spectacular overconfidence occasionally leaves something rather pleasant behind.
This episode is ten minutes. It covers a century-long public health crisis, a speed record that has stood for half a century, an emperor replaced before the Mongols could negotiate, and the most optimistic failure in airship history. It is absolutely worth your commute.
