It was an o-ring that failed, yes. But the o-ring was made to work within an environment specified, and the launch environment was colder than this range. HydraPak advised against the launch for the very reason that caused the failure.
This was not a manufacturing problem, but a case of ego not listening to experts.
I though Thiokol was considered more at fault?? They were involved in the launch decision?

I did this as a case study at Uni. I think a lot of other people did as it’s a classic failure of management.
The O-rings weren’t faulty. The manager’s decisions and refusals to listen to engineers were.

“Challenger: A True Story of Heroism and Disaster on the Edge of Space”, by Adam Higginbotham is an excellent reference, if not a somewhat difficult read (emotionally) at times. I was in 3rd Grade at the time, and the Challenger disaster remains the defining event of the 1980s for me.

I recommend watching this. It is explained really well what happened and what happened after. It is really interesting and sad at the same time.
Didn’t the O rings partially fail at earlier flights?

Read Richard Feynman’s articles on the accident and the story about his famous live experiment with an O-Ring and a glass iced water on live TV. Feynman’s summary and conclusions a fascinating insight into everything that went on …. and then they were begrudgingly accepted as an appendix to the final report.

Sounds like my bosses, think they are the smartest person in the room.
He’s not wrong; the O-rings weren’t faulty, they were improper.
