The 8-Second Call That Saved Apollo 12 — And Then Apollo 13

Thirty-six seconds into launch, lightning struck Apollo 12. Then it struck again. The entire spacecraft went dead.

November 1969. The rocket carried three men, 6.5 million pounds of thrust, and a nation's hope — climbing straight through a live thunderstorm. Its own exhaust trail became a conductor, and the rocket turned into the highest lightning rod in history.

Inside, every warning light fired at once. The fuel cells dropped offline. The guidance platform tumbled. Houston saw nothing but garbage data. Commander Pete Conrad was flying a 363-foot rocket essentially blind. Then a young flight controller named John Aaron remembered a faint, garbled signal pattern he'd seen once before — a year earlier, during an obscure test. Within seconds he called it in: 'Try SCE to Aux.' The flight director had never heard of the switch. Neither had Conrad. The call relayed up to the crew, and lunar module pilot Alan Bean — who happened to know exactly where it was — reached over and flipped it. Every screen in Mission Control blinked back to life.

Apollo 12 landed on the Moon days later — within 600 feet of its target, the most precise lunar landing ever. The mission that nearly ended in catastrophe became the one that proved NASA could survive one. And that young controller, John Aaron? Months later, he'd play a crucial role in saving Apollo 13.
