In the Apollo 13 movie extra material, there are several documentary shots interspersed with commentary about the makings of the movie.
I am interested in the sequence beginning at about 29 minutes (DVD title 1, chapter 7, approximately 2 min 20 sec into the chapter) with Gene Kranz where he talks about the initial problems being referred to as a "funny" and there is a cut to a significantly lower-quality shot showing (him?) in likely Mission Control during the actual mission. There's also a minute later a sequence showing Sy Liebergot discussing the problem of loss of electrical power and oxygen.
I know I have seen these sequences before, and I am certain that I've seen a bit more of both of them; alternatively, something where Kranz and Liebergot said something extremely similar almost down to the specific wording.
Where are those sequences from? Is that NASA footage, some third-party documentary footage that was reused for the extra material, or Howard original footage? Where can I find it (like e.g. documentary title, original broadcast network, archive number with NASA, ...)?
As a bonus question (not required for a valid answer to this question), in what other documentaries has the material been used?
The relevant portions of the ending credits appear to be (which doesn't really help me very much):
