Okay. On step 5 on E-11, there's—the first subtitle there is Helmets and Gloves, and the items that follow beneath that are affected by whether you wear suits or come in shirt sleeves, but they do have to be accomplished. And the suit return air valves would actually be OPEN for a shirt-sleeve entry. And you should have a line penciled in of optics power to OFF between an emergency cabin pressure valve and the time when the CMP moves to the couch.
-
Ken Mattingly (CAPCOM)
-
Okay. And the step shows the tape recorder to REWIND at minus 30. Now that's an onboard step rather than a ground step, just to verify that.
-
Ken Mattingly (CAPCOM)
-
Okay. Under step 6, almost at the bottom—in fact, it's three lines from the bottom of step 6—there's a section that says secondary coolant loop evaporator to RESET, and should be a note that that's 58 seconds if you hold it in RESET prior to moving the pump OFF.
-
Ken Mattingly (CAPCOM)
-
Alright. This is a general comment that refers to any time you're working around P62 or when you're going between P62 and P63, and you should be careful not to call an extended VERB during this time. This is here in the program notes, and it is just a reminder. What will happen if we get into an extended VERB such as an 83 or an 82? We may get hung-up in P62 and have to recycle through it in order to get the 63, and neither of these displays are normally used, and it's just a good practice. And we're just trying to remind you that we don't want to call an extended VERB while we're in P62.
-
Frank Borman (CDR)
-
Okay. Neither do we. That's right.

Okay. In going through the rest of it, we didn't find any other things to make comments on. You have all the latest corrections in your checklist.
-
Frank Borman (CDR)
-
Roger. The main thing, that is to come up with a way to determine that the boiler—water boiler is not dry and make sure that Bill gets it activated at TMS 7.
-
Ken Mattingly (CAPCOM)
-
That is correct, and we will talk to you some more about that next time we catch both you and Bill up.
-
Ken Mattingly (CAPCOM)
-
Okay. I've got a few good words for you. The erasable memory has been taken completely apart and looked at, and it looks like it's all okay. Your P01 didn't have any effect. The one thing that might be questionable is if you used a VERB 67 when you get to the NOUN 99 display, you may find that one to be unreliable, and what you're going to get there is the—that's an error display for the W-matrix. And it's something you probably won't be using again anyhow; and if the occasion arises, we can update that one, but it's not a normally used display and everything else, all the operational functions, are good.

Ken Mattingly (CAPCOM)
-
Okay. As of 114 hours, your batteries—you had battery A with 39.32 amp-hours, battery B had 35.21, and battery C 38.46. Your cryo quantities remaining at SEP were the same we gave you the last time, 180 pounds of oxygen per tank and 11 pounds of hydrogen per tank. At present, the service module RCS, using the computer values for the quantities, you have quad A with 45 percent, Bravo with 50, Charlie with 58, and Delta at 48. What we plan to do with the secondary tanks is to go ahead and turn them on at 37 percent actual, and in the event of lost COMM or something like that, recommend that you use 50 percent onboard gaging as being the time to turn the secondary propellants on. However, as long as we can use our own calculations, why, we might as well leave them tied up. We probably won't get into the secondary propellants prior to entry anyhow.
-
Ken Mattingly (CAPCOM)
-
Okay. A couple of items I want to check up on: I'd like to confirm that the hatch Dog will be taken off while you're on the chutes if you can. If not, you're going to do that in the water. Is that affirm?
-
Ken Mattingly (CAPCOM)
-
Okay. Now we've got a little better signal. Like to confirm that the hatch clamps on the side hatch will be taken off either on the chutes or in the water, whichever you can get to. Is that affirm?
-
Frank Borman (CDR)
-
Roger. That's affirm. As a matter of fact, we didn't even put—didn't even put them on.
-
Frank Borman (CDR)
-
I don't think so. It's held pretty well so far. I don't think—everybody tells me it wouldn't help much anyway.
-
Ken Mattingly (CAPCOM)
-
Okay. And we realize we never did find out what happened to the Mae West. Did you leave it blown up, or did you dump it?
-
Ken Mattingly (CAPCOM)
-
Okay. And just as a gee whiz item: you're now a 137 915 out, and you've only accelerated the 4883. You might check to make sure you don't have a speed brake hanging.
-
Bill Anders (LMP)
-
Good morning, or good afternoon, or whatever it is. The JOD is back at the CON; CDR went back to bed.
-
Bill Anders (LMP)
-
I know what you mean. I had a little sleep earlier, so I am pretty well rested and want to make sure Frank gets a good snooze here prior to entry. This might be a good time to try out your background music, and see if you have any better luck.
-
Ken Mattingly (CAPCOM)
-
Okay. I guess we should start off with a little dialogue about sleep. How much did you have?
-
Bill Anders (LMP)
-
Well, let's see; whenever it was I told you I went to bed last night till now. Just a second and let me check the flight plan.
-
Bill Anders (LMP)
-
Yes. Why don't you let me know. I have kind of lost track of time it was when I went to bed. But it was about—I went to sleep about 15 minutes after that and woke up about 10 minutes ago. Good sleep.
-
Ken Mattingly (CAPCOM)
-
Just trying to find out how soundly you really slept. I guess you are not that sleepy.
-
Ken Mattingly (CAPCOM)
-
Apollo 8, Houston. Have you got somebody under the left couch, or could you get down to the water control panel?
-
Ken Mattingly (CAPCOM)
-
Well, what we were thinking about doing was boiling a little out of the secondary evaporator to check it out, just as a component check, something we need to do; but if there's somebody down there in the way, why, we can do that some other time.
-
Bill Anders (LMP)
-
Well, if it boils, we are going to know it before—it won't take long to find out it won't boil. There's not a heck of a lot we can do about it, so why don't we wait until someone else wakes up here, Frank wakes up again. How will that be?
-
Ken Mattingly (CAPCOM)
-
Yes. That would be fine. There is something you can do; you can reservice it. And it is kind of a tedious process, and that's the reason why we just want to kind of keep our eyes on it so we will have some idea prior to entry if we can count on having two loops or one. Which kind of leads us into another question we are trying to pin down, two questions, in fact. Number one, we would like to verify that you do plan to use both primary and secondary boilers during the actual entry, and we are also looking for a way of checking the primary boiler to make sure it isn't dried out prior to entry. And that is turning into a little more of a challenge than you might suspect. If you have any thoughts on that subject, we can go over that.
-
Bill Anders (LMP)
-
The answer to the question is yes, we do plan to use both. Before we get into the water boiler pump though, CDR would like to take a Seconal also; make sure he can get off to sleep here.
-
Bill Anders (LMP)
-
Okay. On the water boiler: it's interesting that I get my own—I was going to say anytime you have our mike keyed, I can hear myself talk with about a 2-second time delay. With respect to the primary and secondary boiler checks, I think that is a good idea to make sure we got them both prior to entry and have the reservicing procedures handy.
-
Ken Mattingly (CAPCOM)
-
Roger, Bill. You know the secondary—well, in fact, both reservicing procedures are available in a malfunction book, and sort of the problem with checking out the primary boiler is finding a way to make it boil on the way in.
-
Bill Anders (LMP)
-
Roger. It looks like the only way we'll be able to do it would be to shut off the radiators.
-
Bill Anders (LMP)
-
Roger. That way would be agreeable to me too, a little more docile way, but they shouldn't freeze up if we did it quickly.
-
Ken Mattingly (CAPCOM)
-
Roger. We are talking over several things, you know, like putting the ten-pin valve to MANUAL or partially closing it or some of these different ideas, and something you can think about while you are laying there with nothing else to do.
-
Bill Anders (LMP)
-
Yes. We noticed that it had gotten warmer in the cockpit coming back than it was going out. And I remember going out when we manually positioned the ten-pin valve, but we had pretty good control over the glycol evap outlet temperature. So possibly that would be the thing to attack first rather than the radiators.
-
Bill Anders (LMP)
-
I guess if we do pick a time, though, we ought to pick a time that if something did go haywire, we could afford to boil . . . the rest of the way in, but still leave us enough time to fix—rig up the evap service if it didn't work.
-
Ken Mattingly (CAPCOM)
-
That's affirm, and we're factoring in things like trajectory considerations and all that sort of thing, too.
-
Bill Anders (LMP)
-
Right. I think that the second derivative of the water boiler versus time plot will give us the optimum time to do it.
-
Ken Mattingly (CAPCOM)
-
There's also speculation you have a chart on board that gives that information.
-
Bill Anders (LMP)
-
Well, if I don't, I'm sure those guys can ship one up. They've shipped up some other pretty good ones.
-
Ken Mattingly (CAPCOM)
-
It's also been suggested that if you don't have the chart it's on the tape recorder.
-
Bill Anders (LMP)
-
Okay. I think, unless you guys got some more comments along these lines, maybe we ought to give these guys a chance to get to sleep, and I'll recline here for a while. If you've got something to brief me on, well, go ahead; but I'd like to keep my answers to yes's and no's and whatever else you think you really need.
-
Ken Mattingly (CAPCOM)
-
Okay. Fine, Bill, and I'll check with you like every 30 minutes, just to make sure we still have voice contact.
-
Bill Anders (LMP)
-
Okay. I've got some log writing to do and whatnot. So keep an eye on the systems and the gimbal angles, and we'll be all right.
-
Bill Anders (LMP)
-
And, Ken, if your EECOM man wants to play the OMNI-switch game, we're on Dog—Bravo at this time, actually on Bravo but also configured for D's—correction, we are on D and also configured for Bravo. If you want to switch, we'll go ahead.
-
Ken Mattingly (CAPCOM)
-
Okay, we'll give that a try, and we are cranking up some Background music for you.
-
Bill Anders (LMP)
-
Okay. The last time they did that, it sounded like they were running at the wrong speed on the tape, but we're a little closer now. Maybe it'll be a little better.
-
Ken Mattingly (CAPCOM)
-
Looks like we can use your humming for backup ranging in case everything else fails.
-
Ken Mattingly (CAPCOM)
-
Apollo 8, Houston. You don't need to answer this transmission, but doctors observe that it looks like your—some of your sensors may be working loose, so you might just kind of push on them and see if they are in place.
-
Ken Mattingly (CAPCOM)
-
Apollo 8. We can't handle the OMNI switching for about thirty more minutes, till we get back to an 85-foot dish, so you will have to watch the antenna store for a few more minutes.
-
Ken Mattingly (CAPCOM)
-
No, I didn't. It sounded like you were getting an echo, and I checked, and I hadn't held the key down at the time either.
-
Bill Anders (LMP)
-
Okay. I don't see any loose sensors, but the upper sternal is beginning to irritate a little bit, but not badly; and possibly there is something going on there.
-
Ken Mattingly (CAPCOM)
-
Apollo 8, Houston in the blind now. We're not receiving down-voice. We have data, and it appears it's probably a ground problem.
-
Ken Mattingly (CAPCOM)
-
Okay. I got you that time. I take it you were able to copy us with the music? Is that affirm?
-
Bill Anders (LMP)
-
I was able to copy you all the time, Ken, but I could only hear the music when you were trying to transmit. And I wondered if you noticed cycling on my suit power switch when you—when you called me. I am hearing an echo now.
-
Bill Anders (LMP)
-
I was cycling the suit power which turns off the BIOMED periodically. I figured that would wake the doctors up.
-
Bill Anders (LMP)
-
Roger. Be advised that about 50—I am hearing these echos quite a bit of the time, and if you are trying to play music, I am not hearing it.
-
Ken Mattingly (CAPCOM)
-
Apollo 8, Houston. Going to be handling over sites at 25. I will make a voice check with you when we come up on the new site, and the ground says thank you for your kind words.
-
Ken Mattingly (CAPCOM)
-
Okay, Bill, and our BIOMED data still looks a little bit squirrelly. How about checking the blue signal conditioner on your BIOMED harness. You have one connector, should be the center package, has a blue connector on it. You kind of check that, and I don't know if you have changed the BIOMED harness leads recently; if you have, this might have caused our problem.
-
Bill Anders (LMP)
-
Roger. I was just cracking open some acorns here for breakfast. Let me put them down, and I will check my BIOMED leads.
