Okay, Jim. Since the first recommendation on how to maneuver PTC didn't work out, we have another one. And you might try this. Put yaw at zero, then start the roll, and the pitch after that.

Key moment Mission control describes the 'mailbox' CO2 scrubbers: Okay. You guys just tell me what sort of material you had in mind to build this mailbox out of, and Jack and I will go to work on trying to construct that thing. Assume we'll use the space-age baling wire or the gray tape?
-
Vance Brand (CAPCOM)
-
That's affirm. We have a lengthy procedure here; but, in short, you use plastic as a covering for the whole thing. You put some kind of a stiffener at the top so the plastic doesn't suck against the LOI—LiOH enter—entrance side. You'll—You need gray tape to stick the whole thing together, and you need something like a sock to put in the—the bottom so that the outlet side is plugged up. As it turns out, the flow is rather U-shaped through the cartridge, Fred. It, if you plug up the bottom, it comes in one side of the top and goes out the other.
-
Fred Haise (LMP)
-
Okay. (Sigh) Hold on a minute. Let—Let us go get a cartridge and with it in hand, I'll speak to you some more.
-
Vance Brand (CAPCOM)
-
Okay. Really, I think we should give you a more detailed procedure on that; and, in general, those are the materials that are to be used, but let us get back with a detailed procedure on how to make this cartridge arrangement work.

And to answer your question about PTC, Vance, it's rather difficult to use yaw in zero right away. So what I'm doing, yaw is working toward zero right now. Pitch is working toward 90, and roll is working toward—zero. So, we—We're just going to take some time to get there, that's all.
-
Vance Brand (CAPCOM)
-
Roger. Quite a bit of noise now. I understand you're still having a problem getting there with the PTC.
-
Jim Lovell (CDR)
-
Yes, I've been trying to get roll out. Roll to zero. Just go ahead to zero, I'm going to put it in ATT HOLD. Then it'll take out yaw, leaving pitch the way it is; then we're going to pitch down.
-
Jim Lovell (CDR)
-
It's in. That's how it triggers the—Okay, Jack. I'm going to push in on this thing to stop it.
-
Fred Haise (LMP)
-
That just turned the MASTER ALARM back on. Now that it's on steady, I'll leave it on. I can't understand why I got a power—Oh, I know. That's right. … That reading is correct.
-
Vance Brand (CAPCOM)
-
Jim, it looks pretty good except that the pitch is going out in the wrong direction, now. Over.
-
Jim Lovell (CDR)
-
I concur. What I'm going to do is get roll to zero and I'm trying to bring yaw into zero and as soon as I get those two pretty well matched up, then I'm going to take the pitch and try to pitch it down.
-
Jim Lovell (CDR)
-
Okay. Now I've got pitch going down; I've got roll almost zero and yaw is almost zero.
-
Jim Lovell (CDR)
-
Roger. What's the acceptable pitch attitude that we can have for PTC? I can go into AUTO any time now, I'm looking at 118 degrees in pitch, practically zero roll, and about 40 degrees of yaw.
-
Jim Lovell (CDR)
-
Okay. It's coming down. What's that? Well, I guess I'd better eat something. Hey, this one has some of that candied jelly … you know, we've gone a hell of a long time without any sleep. I said we've gone a hell of a long time without any sleep.
-
Jim Lovell (CDR)
-
We'll have to start thinking about getting the … back to sleep again because—I know—I—I didn't get hardly any sleep last night at all.

Hey, Fred? These jettison bags with the—are real airtight stuff, if you want to use them for wrapping for a lithium hydroxide bag or something like that.
-
Vance Brand (CAPCOM)
-
Okay, Jim. Would you stable your—stabilize your rates here at the attitudes you're at now and go ATT HOLD. Over.
-
Jim Lovell (CDR)
-
Last one's in the trash bag. Oh, I thought—if you wanted a …, you'll have to use the lithium hydroxide …

Okay, Houston. Are you monitoring my angles? It appears that it might be less then 1 degree per second.
-
Vance Brand (CAPCOM)
-
Jim, that's affirm. We're monitoring and you're almost there, but we'd like to let them stabilize a little bit longer. Over.
