Okay, Apollo 8. We have looked at the data and it looks good and they feel like you can go back to PTC attitude anytime you are ready to. And if you can—go ahead.
- Ken Mattingly (CAPCOM)
-
Okay, if you can reach over Bill there and get to panel 3, I believe we would like to cycle the oxygen fans. And also like to get the BIOMED switch over to CMP.
- Ken Mattingly (CAPCOM)
-
If you have to bother Bill to do that, why, we can hold off on the cryo fans.
- Frank Borman (CDR)
-
No, he moved. We already chased him under the seat. Okay, now you want just the oxygen fans on?
- Ken Mattingly (CAPCOM)
-
That's affirm. Turn one on for about 2 minutes and when we turn it off, then we will turn the next one on. We don't want to turn them on simultaneously though.

Ken, just recap a little explanation here on your maneuver PAD, something which I'm really not knowledgeable about, the way it was presented to us, you mentioned fast return P37 DELTA-V of 8750, just briefly clarify that, will you please?
- Frank Borman (CDR)
-
Ken, can you give us a little report on how our trajectory looks and the tracking is going and things like that?
- Bill Anders (LMP)
-
Houston, Apollo 8 is back in the PTC attitude, reads MHPTC.

Okay, thank you. And in reference to your question about the P37 DELTA-V, 8750, that's the number that goes into the option at P37 for your minimum time return. That gives you a target for the Indian Ocean. And in this case, we are going to have to use the high-speed procedures that were worked out for you to use some minus number for the major axis.

Roger. Understand. I'm going to give that a try, Ken, in a run through. I tried it yesterday, I wasn't getting too much in the way of results. I will give it a try today.
- Ken Mattingly (CAPCOM)

Okay. And on the—your tracking that we have now, it still looks like the time we gave you last night for time of pericynthian is still good, 69 plus 10 and right now your flyby earth pericynthian altitude is 65.8. Looks like the midcourse number 3 is going to be something less than 1 foot-per-second. And all trajectory parameters are still holding real fine.
- Frank Borman (CDR)
-
That's the things we like to hear. We would like to keep those holding very much.
- Frank Borman (CDR)
-
Roger. We're getting near—we're going to need to dump some urine overboard here. I wonder if that's going to foul your trajectory up. Or can we go ahead and do it?
- Ken Mattingly (CAPCOM)
-
No, that's okay. Something that is kind of interesting though is that the last time you had your water dump, they noticed a change in the trajectory tracking at the same time and they got through correlating it, they found some fellow that thought he knew the characteristics of a nozzle and how much water you're dumping and his estimates of the effect on the trajectory seemed to coincide with the tracked results. So I guess you have to stay onto some of those things.
