The following is an excerpt from the transcript of the Apollo 11 technical debriefing; Aldrin: The first unusual thing that we saw I guess was one day out or something pretty close to the moon. It had a sizeable dimension to it, so we put the monocular on it. Collins: How'd we see this thing ? Did we just look out the window and there it was. Aldrin: Yes, and we weren't sure but what it might be the S-IVB. We called the ground and were told the S-IVB was 6,000 miles away. We had a problem with the high gain about this time, didn't we ? Collins: There was something. We felt a bump or maybe I just imagined it. Armstrong: He was wondering whether the MESA had come off. Collins: I don't guess we felt anything. Aldrin: Of course, we were seeing all sorts of little objects going by at the various dumps and then we happened to see this one brighter object going by. We couldn't think of anything else it could be other than the S-IVB. We looked at it through the monocular and it seemed to have a bit of an L shape to it.
