Challenger Launch Failure, Remember This?

[nzoomed]

I remember watching an interview with him, in no way was he happy to approve the launch and was literally waiting for it to explode during launch, terrible tragedy that could have been avoided.
Morton Thiokol essentially threw him under the bus, but he ended up leaving the company IIRC.
The blame really lied 100% with NASA for pressuring the company executives to go ahead with the launch, they should have known better.
