Great broadcast! "That's the main engine I think, and that's the booster. Wow! And there it goes, goodness me!" is one of those audio clips that we will hear for generations to come. And I suspect many of the same phrases were heard at mission control that day, such as "I don't fully understand how [Lagrange point] works" and "You want to do that otherwise you end up with a rather wishy-washy bit of turkey, don't you?"
