On January 28, 1986, a bitter cold morning at Cape Canaveral, the Space Shuttle Challenger launched with seven astronauts aboard. Just over a minute later, it exploded in front of millions watching live television. None of the crew survived. The official investigations eventually traced the cause to a failed O-ring—a rubber gasket designed to seal joints on the rocket boosters. But the deeper story, told here through the voice of Brian Russell, the young engineer who had spent the day before the launch trying to stop it, is about what happens when dissent gets swallowed by hierarchy.

The engineer who saw it coming

Brian Russell worked for Morton Thiokol, the company NASA had contracted to build the shuttle's solid rocket boosters. He was part of a team dedicated to ensuring the O-rings worked properly. In the months before the launch, Russell and his colleagues had been warning that cold temperatures could make the O-rings too stiff to seal properly. The day before the launch, when weather forecasts predicted overnight temperatures far below any previous launch, his boss came to his cubicle and asked if he had any concerns. Russell answered immediately: the O-rings.
