Ask HN: Examples of successful waterfall-style projects?

I'm curious if there's anecdotes from people who worked at highly successful waterfall projects, that is, structured, planned projects that achieved their objectives. I'd like to know what things you thought made the project successful, how the bureaucracy helped or didn't help, and any other thoughts you might have. A project that comes to my mind is the Apollo rocket project, which made many innovations and put together tends of thousands of people together and achieved its goal.
