The technical answer of what part failed and why is only a small part of the overall answer, though.
For example, with the Challenger explosion, it's O-rings vs. the culture and organizational deficits that led to: the O-rings, failure to revise the seal structure despite evidence of problems on prior launches, and the final decision to launch Challenger.
All of that is arguably the most interesting part.
