Apollo 13: Four Days in a Lifeboat Built for Two

Fifty-five hours, fifty-four minutes and fifty-three seconds into the flight of Apollo 13, Mission Control asked the crew to stir the oxygen tanks. There was a bang. Minutes later, Jim Lovell looked out the window and saw their oxygen venting into space — nearly 200,000 miles from Earth. Four days later, three men splashed down alive in the South Pacific, brought home by a lunar lander built to keep two men alive for about two days. This is the story of how the crew and thousands of engineers on the ground turned Aquarius into a lifeboat: a descent-engine burn to get back on a free-return path, a spacecraft powered down to the electricity of a few light bulbs, a carbon dioxide filter improvised from plastic bags, cardboard and tape, a course correction flown by hand using the edge of the Earth in the window, and a frozen command module brought back to life for reentry. And it is the story of the hidden flaw — a damaged thermostatic switch inside oxygen tank number two — that had been waiting in the spacecraft since before it left the ground.
