We have had a couple of meetings of FCD, FSD, MPAD and IBM people to discuss some of the RTCC computer program requirements for the lunar landing missions. One item coming out of these discussions, which may interest you, is that there is currently no intention of carrying an ephemeris for the S-IVB after it separates from the Apollo space- craft. As you know, there have been recurring discussions of the need for this in order to evaluate the possibility of recontact. I should point out that this was not really an area of disagreement among these people. I think it was fairly well agreed that the random venting of the tanks following loss of attitude control and ground tracking capabilities would make any such ephemeris meaningless.
