Fred Haise (LMP)

That's 2 Bravo is reading—oh, about 0.25 to 0.3.

Fred Haise (LMP)

Okay. 2-C is reading 4.1.

Fred Haise (LMP)

And 3-A is reading 4.0.

Jack Lousma (CAPCOM)

Roger. 4.0. Say again what it is, please.

Fred Haise (LMP)

And 3-D is reading 1.95.

Fred Haise (LMP)

And, Houston, 13. O2 tank pressure number 1 is less than 300 now.

Jack Lousma (CAPCOM)

Roger. We're seeing that. We confirm it.

Jack Lousma (CAPCOM)

13, Houston. We're going to have to have you go through the shutdown procedure on fuel cell 1. Our O2 pressure is going down as you note and the temperature confirms it. Did you copy?

Jack Swigert (CMP)

Okay. Well, what bus configuration—What main bus do you want powered?

Jack Lousma (CAPCOM)

Okay, Jack. We want you to leave the bus configuration as it is. Fuel cell 2 on MAIN A, and we need OMNI Bravo.

Jack Swigert (CMP)

Okay, Jack. We're proceeding on the shutdown procedure for fuel cell 1.

Jack Lousma (CAPCOM)

And, 13, Houston. We'd like you to isolate the REPRESS package, please.

Jim Lovell (CDR)

Isolate the REPRESS package. Roger.

Fred Haise (LMP)

I can confirm REPRESS package is off.

Jack Lousma (CAPCOM)

Roger. So now you've got the REPRESS package and the surge tank isolated. Is that affirm?

Jack Swigert (CMP)

Okay. Now, this is—We're ready to close the REACs on fuel cell 1; is that right?

Jack Lousma (CAPCOM)

Jack, stand by on the fuel —

Jack Swigert (CMP)

On that last—confirmation. Okay.

Jack Lousma (CAPCOM)

Roger. We're—We're giving you one last —

Jack Swigert (CMP)

We want to just get one last confirmation.

Jack Lousma (CAPCOM)

Okay, Jack. We're getting that last confirmation. Stand by, please.

Jack Lousma (CAPCOM)

Okay, 13. We verify that we want you to close down—shut down fuel cell 1, close REACs valve.

Jim Lovell (CDR)

— fuel cell 1; close the REACs valve.

Jim Lovell (CDR)

REACs valve on fuel cell 1 is closed.

Jack Swigert (CMP)

Okay, Jack. I can confirm step 2. The fuel cell shutdown procedure is complete for fuel cell 1.

Jack Lousma (CAPCOM)

13, we recommend that you enable BD roll in the DAP. Over.

Jack Lousma (CAPCOM)

13, Houston. We're working on the big dish now, so turn the HIGH GAIN POWER switch off, please.

Jack Swigert (CMP)

Okay, Jack. When we got the loud bang, we got also a restart. Did you copy that? Is—does GUIDO want anything, a VERB 74 or anything done with the CMC?

Jack Lousma (CAPCOM)

13, Houston. We're ready with a VERB 74 now, please.

Jack Swigert (CMP)

Key moment With oxygen dropping, the crew considers a move to the LM: Okay, Jack. It looks like O2 tank 1 pressure is just a hair over 200.

Jack Lousma (CAPCOM)

We confirm that here and the temperature also confirms it.

Jack Swigert (CMP)

Okay. Does it look like it's still going down?

Jack Lousma (CAPCOM)

It's slowly going to zero, and we're starting to think about the LM lifeboat.

Jack Swigert (CMP)

Yes. That's what we're thinking about, too. You want me to do a quick P52? It kind of looks like—We've been talking it over, and it kind of looks like we'd probably aline our plats—LM platform with our platform and then power down the CM, and keep the LM powered up doing a DPS—whatever DPS burns you give us?

Jack Lousma (CAPCOM)

13, we're not going to concern ourselves at the moment with a DPS burn. It's going to be some time before we'd get to that; but we're working on other procedures to give you, which will allow us to use the LM systems. Over.
