Age: 89

booster rocket engineer at NASA contractor Morton Thiokol in 1986 who spent 30 years filled with guilt over not being able to stop the explosion of the space shuttle Challenger after a handful of his colleagues worried that the cold temperatures the night before the Challenger was set to launch would harm the rubber O-ring reals and allow burning rocket fuel to leak out of booster joints, who warned his boss the morning before the launch of the dangers that could face the Challenger if it was sent into space that day as he collected data that illustrated the risks and spent hours arguing to postpone sending the shuttle and its seven astronauts into space but could not convince NASA to postpone the launch.
