Apollo 8: Part 2Feb. 1, 2019
(...)
Walt Cunningham: Well, it's interesting. Some of the things that the public is not aware of because it isn't in kind of the public record about it but originally Apollo 8 was essentially the same kind of test mission as we had on 7 except they were going to be going out I think 8,000 feet -- 8,000 feet -- 8,000 miles away from the earth to do it. But that decision was an administrative decision that was worked on, had a lot of debating going on back and forth, but they started training Apollo 8 to do that about 8 or 10 weeks, about 8 weeks before we flew. And so they were trained up to do it but they could not get approvals to do that unless we had that test flight. So two weeks after we flew, people think that that's when they dreamed up to send Apollo 8 to the moon. No, they were trained in doing that for a long time and after we were successful is when they committed to go out and do it.
Gerry Griffin: That's funny. Because I remember, Glynn, I don't know when you got right into 8, but I was a flight director with Glynn on 7. I didn't know we were going to go to the moon until after we splashed down on 7.
Glynn Lunney: I didn't know either. And I was walking out of the control center when the flight -- the Apollo 7 flight was over, and Cliff Charlesworth sidled up to me and says, I have to tell you what we're going to do next. [Laughter]. And he did. My first reaction was, we can't do that. We're not ready and rrr, rrr, rrr. But that was a typical reaction that everybody had because it was a new thought for people. But when we thought about it for a while, we had to go into lunar orbit sooner or later. So why not now? What are we waiting for? And there wasn't any answer to what are we waiting for, except that it was a big step. And I have to say that Apollo 8 -- following Apollo 7 and Apollo 8, it was like we were on a slide downhill to get to the lunar manning missing. That we flew a flight -- earth to orbit exercise and everything. We had to exercise. And then we flew a flight into lunar orbit doing the same thing. And by that time, we were ready to call for a landing. (...)
