HN cites it for Feynman's insights on NASA risk reasoning, blame and engineering culture, and the contrast between Apollo and the Shuttle.
A June 1986 CNN interview with physicist Richard Feynman about the Challenger disaster and the management failures he found while serving on the investigating commission.
“Richard Feynman served on the Challenger commission and very nicely summarizes the difference between Apollo and Space Shuttle.” (HN, 2025)
It was reusable, but way over promised. Don't take my word for it. Richard Feynman served on the Challenger commission and very nicely summarizes the difference between Apollo and Space Shuttle. [this video] SpaceX is doing stuff that's just beyond the scope of what's deemed conventionally realistic. That's achievable and pushes us forward.
Feynman summarizes difference between Apollo and Space Shuttle.
> the absence of known danger is not the same as safety. Feynman had some interesting comments on this problem regarding NASA's "it worked ok last time" approach to risk assessment before the Challenger Disaster. [this video]
Feynman on NASA's it-worked-last-time risk reasoning.
> the model of 'public by default, opt in for security' is fundamentally daft in this context. It's daft in most contexts, and is one of the largest sources of security problems. If your design requires enumerating badness [1], you're doing it wrong. > from: [link] >> Just about every ICO, trust and company used the Parity multisig wallet, and that code was considered well-tested. -sigh- This is, unfortunately, a common problem. "It worked ok the last N times" and "It passed a lot of tests" do not mean it's bug-free and safe to use. Richard Feynman was right during the Challenger investigation when he called this a childish attitude . (He was also right in not wanting to assign blame, instead asking "How do we educate the child?"[2]) [1] [link] [2] [this video]
