Episode description as stored
On January 28, 1986, the Space Shuttle Challenger exploded 73 seconds after liftoff. All seven astronauts onboard died. Brian Russell, an engineer who worked on the shuttle, had spent months warning NASA that freezing temperatures could cause a critical seal to fail. In this episode, Brian Russell takes us to the intense meeting where NASA had to decide whether to launch and the 40-year weight of a tragedy he tried to prevent.
