After serving on the support crew of Skylab 4, Schweickart was more interested in cultivating managerial skills than "[going] over to the Space Shuttle development work which was under way ... by that time, I had, you know, done a lot of work on Gemini in a support role, and then, of course, everything on Apollo, and now all of this on Skylab, and to go cycle back into the very beginning of the Space Shuttle, which was not going to fly for, at that point, something like six years and best guess of anybody in the business was maybe eight years, I figured, you know, another eight years of basically going to the same kinds of meetings, making the same kinds of decisions, going to the same places ... it was like 'been there, done that.'"
