Ken Mattingly

— you have plenty of water. I'm sorry we cut each other out; say again.

Jack Swigert (CMP)

Okay, yes. I was going to say, understand we're going to go on the ascent tanks at 128:30.

Ken Mattingly

That's right; based on the current rate, that's what they predict and you can go ahead and drink the water. No sweat.

Jack Swigert (CMP)

Okay, real fine. And I've got the entry checklist out and I'm ready to copy; just give me the page.

Ken Mattingly

Okay. Jack, you're starting to sound like an LMP.

Jack Swigert (CMP)

I think I'm probably the only CMP that's ever witnessed an—a LM burn from inside the LM in—in space flight.

Ken Mattingly

(Laughter) I hope it stays that way. Okay, Jack, we're starting on page 1-1.

Ken Mattingly

Okay, down in the middle of the page on line 9, we're just going to strike out the “Activate VHF for COMM checks,” and line 10, “Verify the DSE.” We're going to leave the DSE OFF, and that's to save power, as is the VHF activation.

Ken Mattingly

Okay, on page 1-2. At minus 2 hours, there's a title “Logic sequence” check; and we're deleting that entire sequence; that's included in what I read up to you.

Jack Swigert (CMP)

Okay, delete the logic sequence check at minus 2 hours there.

Ken Mattingly

That's correct. And delete lines 23, 24, and 25. That means a maneuver to SUPERCIRC entry attitude. Everything below that is deleted.

Ken Mattingly

Okay. Delete lines 23 through 28.

Ken Mattingly

That's correct. You got ahead of me. All right, on line 29 on page 1-3, we're going to put in a time of minus 00:55. That's the time we gave you for the boresight check.

Ken Mattingly

That's your sextant check, really.

Ken Mattingly

Okay, on the top of page 1-4; where it said “1 hour and 15 minutes” next to line 32, we're going to change that to “Minus 2 hours and 30 minutes.”

Jack Swigert (CMP)

Okay, minus 02:30 opposite item 32.

Ken Mattingly

Okay, down at the bottom of the EMS entry check right there where we are, the bottom line now reads, “EMS MODE to STANDBY.” Well, just above that—like to remind you to put a remark, “Do not initialize the range to go.” This is because you're going to come into the EMS entry check, you're going to run through all these things; then we're going to remove power from the EMS. And just didn't want you to get ahead of yourself and initialize the entry parameters, because you'll lose them when we power up.

Ken Mattingly

And, after we go EMS MODE to STANDBY, like for you to add “Circuit breaker EMS, two, to open.”

Jack Swigert (CMP)

Okay, “CB EMS, two, to open.”

Ken Mattingly

That's correct. And we want to delete this “Set up camera” that's listed on the bottom of the page. We're deleting that for power reasons. That's line 33 Alfa.

Jack Swigert (CMP)

Okay, we're way ahead of you. We already got it stowed.

Ken Mattingly

Okay. On the top of the next page where it says “Secondary water EVAP,” just keep in mind we don't plan to use the secondary evaporators unless the primary fails. On line 35 on page 1-5, next to “Command module RCS preheat,” the time is now “Minus 06:30.”

Jack Swigert (CMP)

Okay, “minus 06:30,” and the voltage reading 3.9 still is good, right?

Ken Mattingly

Okay, very good. Under “Final stowage,” the first thing that's listed on line 36, page 1-5, is “Optics.” And if you want to get started on your stowage, we'd like to leave the optics out, because we'll have the star check coming up quite a bit after this. The rest of that stuff can be taken care of at your convenience.

Ken Mattingly

All right, still on pace 1-5, line 37; the time is now “Minus 06:10.”

Ken Mattingly

Okay, and this is one time it looks like we might actually do the preheat, so that's the reason we want to make sure that we know that not more than 20 minutes of time on the preheat. We may not be able to watch it at that time because you aren't powered up.

Jack Swigert (CMP)

Okay. Either 20 minutes or until 3.9 volts DC.

Ken Mattingly

That's correct, Jack. And now let's go to page 1-6. And about one-third of the way down, it shows “Panel 275 CB MAIN A, BAT C, closed,” we want to strike off that line, the next two lines, and we're going to strike out “MAIN A, BAT C, closed; MAIN B, BAT C, closed; and DC INDICATOR, MAIN B.”

Jack Swigert (CMP)

Okay. After that step on panel 275, strike out “CB MAIN A, BAT C; CB MAIN B, BAT C; and DC INDICATORS to MAIN B.”

Ken Mattingly

That's correct. Now reader panel 8, it tells you to “Close all circuit breakers EXCEPT,” and I have four additions. The first one is CB SERVICE MODULE RCS HEATERS, QUAD Charlie, MAIN B, open.

Jack Swigert (CMP)

SERVICE MODULE RCS HEATERS, QUAD Charlie, MAIN Baker, open.

Ken Mattingly

Okay. And the same thing for SERVICE MODULE RCS HEADERS, QUAD Delta, MAIN A, open.

Jack Swigert (CMP)

SERVICE MODULE RCS HEATERS, QUAD Delta, MAIN A, open.

Ken Mattingly

That's correct. And Circuit breaker EMS, that's two of them, open.

Ken Mattingly

All right. And the last is the circuit breakers for SPS GAGING, four of them, open.

Jack Swigert (CMP)

SPS GAGING, four to open.

Ken Mattingly

Okay. And how about our readout on the battery and that charger?

Jack Swigert (CMP)

Okay, BAT's at volts and amps.

Ken Mattingly

That's affirmed. And let's go back to page 1-6, line 41. Let's put in a time “Minus 04:40.”

Ken Mattingly

That's correct. On page 2-1, line number 2, put in a time of “Minus 55 minutes.”

Jack Swigert (CMP)

Okay, minus 55 minutes.
