CABIN GAS RETURN, EGRESS.

CABIN GAS RETURN, EGRESS.

SUIT GAS DIVERTER, EGRESS.

GAS DIVERTER, EGRESS.

SUIT ISOLATION valves, two of them, DISCONNECT.

Okay. ISO valves, two, to SUIT DISCONNECT.

Roger. PRESSURE REGs A and B, close.

REGs A and B to close.

CABIN REPRESS valve, close.

REPRESS VALVE, close.

SUIT FAN, OFF.

How many more steps, Vance?

Two after this, Fred-o.

Okay. Stand by.

Maybe you need a scroll, yet.

Yes.

I want to ask him why all these steps just to get rid of a LM that's going to burn up in a half hour. Seems ridiculous. God damn it. Too many guys —

SUIT FAN, OFF.

— got in the act.

Okay. The last one was SUIT FAN, OFF. Hey, Jim, Deke said he thought you were asleep.

Okay. All these steps woke me up.

Okay. We'll try to be quieter. Except I don't know how. Okay, Fred-o —

I got my audio breaker on.

Did you get SUIT FAN, OFF?

Yes. SUIT FAN, OFF.

Okay. Circuit breakers, panel—circuit breaker panel 16 rather. ECS, CABIN REPRESS to open.

Okay. CB panel 16, ECS, CABIN REPRESS, open.

Roger. OVERHEAD DUMP VALVE, closed. Maybe Jim has a point there, though.

Yes. OVERHEAD DUMP VALVE close, and it is already.

Right. Okay. That's all for the ECS. Next, ATTITUDE CONTROL, three, to MODE CONTROL.

Okay. Stand by 1.

Oh, stand by 1, Fred. We'd like to—change the position of that ATTITUDE CONTROL, three, MODE CONTROL to be just under CM free. That's a more convenient time.

Yes, I agree. Okay. Under, it'll be my item B, after verify CM free, it's ATT CONTROL, three, to MODE CONTROL.

And, along with that, DEADBAND, MAX.

Okay. Three to MODE CONTROL, comma, DEADBAND to MAX.

Next verify —

If I don't sound too clear, it's because I'm holding a flashlight between my teeth.

Roger.

Okay.

Okay. Now —

Okay. I think I'm—I'm up with you. Go ahead, Vance.

Okay. Now again down at the bottom beneath ECS, verify transfer list.

Okay. Verify transfer list.

IVT to CM, and close hatch.

What was that—What was the first part of that?

Transfer yourself to the CM. Or rather, IVT, that's the commander to the CM, and close hatch.

Okay.

Turn to 30-minute activation on page 24.

Okay. I'm there.

Okay. Now, at this point, you have this section marked up already, so what I give you now represents additional DELTAs to your previously marked up checklist.

Okay. That's all right. I've got a different color pen, so it'll show up nicely. Go ahead.

Okay. Okay. Go down to item 4.

Roger.

Verify ACS STATUS switch, OFF. That's an addition.

Do you mean, under IVT to the LM, number 4, RCS SYSTEM A/B-2, QUADs 4, AUTO? That 4?

That's affirm. Yes. It's the—the only 4 on that page 24 and it's a—presently has after it RCS SYSTEM A/B-2, QUADs, 4, to AUTO. Under that put —

Roger.

— put verify AGS STATUS switch to OFF.

Okay. Verify AGS STATUS switch OFF.

Okay. At the bottom of the page—Okay. You already have that. MODE CONTROL, both, OFF.

Okay. Next, page 26, circuit breakers.

Okay. Go ahead.

Okay. First row is okay as is. Second row, under FLIGHT DISPLAYS, GASTA should be closed.

Okay.

Under AC BUS A, close GASTA.

Okay. GASTA FLIGHT DISPLAYS and AC BUS A will be closed.

Roger. That's all on the second line. Now the third line, under STABILITY and CONTROL, ATCA (PGNS) to closed.

Okay. ATCA (PGNS) to close.

That's all on that line. Fourth line, near the right side, LGC STANDBY to close. And —

Wait a minute. You mean LGC/DSKY.

LGC/DSKY. I'm sorry.

Okay.

And IMU OPERATE, close.

Okay. IMU OPERATE, close.

Okay, Vance. IMU OPERATE, close.

That's correct. Okay. Fourth row is okay as is. Now we would like to add—add in a late arrival to row two. Under —

Go ahead.

Under FLIGHT DISPLAYS, MISSION TIMER, closed.

Okay. FLIGHT DISPLAYS, MISSION TIMER, closed. We can look at the ghosties right to the end.

Yes, that's right. Okay. That's all for that page, Fred. That should add up to six circuit breakers all closed, on that page.

Vance, Jim.

Go ahead, Jim.

Have we looked seriously now at just the essential things required to make a safe LM jettison? We're not—I don't think we have the time to really do any engineering data that people might want to look at as this thing goes into the atmosphere.

Well, Jim. I—I think that that was what everybody aimed for, and people down here feel that it's the essentials, that it's what you need.

Well, we'll do everything you think is essential, but I just don't want to be throwing switches at the last minute. What we're really thinking about, getting that command module in good shape.

Hey, Jim. This is Tom. The only reason we're bringing up the PGNS is to have another reference system just to control the LM when you jettison the thing. Over.

Okay. Okay, Tom. It's—I thought the—an AGS ATT HOLD would have been sufficient for this, when we first thought about this.

Yes. I agree. But we decided just in case we have any glitch with the AGS, we want to make sure we get that LM off in a good shape. And I agree with you on keeping out all the garbage on it.

Okay, Tom.

Hey, would you like to have —

Good night.

Would you like to have us play you some guitar music to put you to sleep?

(Laughter) Oh, you know how to get to a guy.

We'll even have a 12-string guitar for you, Jimbo.

Okay.
