That's affirm. And the two lines below “30 seconds.” And actually the part of the fourth line there, which is “8-1/2 minutes.”
-
Jack Swigert (CMP)
-
Okay. Delete the two lines below that, or the two-and-a-half lines below that, also.
-
Vance Brand (CAPCOM)
-
That's affirm. And now, we have an addition to put in place of what we deleted. Stand by 1; the COMM's bad. How do you read?
-
Vance Brand (CAPCOM)
-
Okay. We want you to vent—tunnel vent until, and add the following, “Until LM/CM DELTA-P is equal to 3.0 psid.”
-
Vance Brand (CAPCOM)
-
Okay. And that means that you'll have a pressure of 1.5 to 2 in the tunnel, absolute. That's —
-
Deke Slayton
-
Jack, that's what we want to end up with ultimately is 1-1/2 to 2 there in that tunnel and depending on the gage reading, but that should be about 3.
-
Vance Brand (CAPCOM)
-
Okay, then, Jack. Continuing on, everything's okay until you get down to—on the next page, you get through “Verify O2 FLOW INDICATOR no increase.” We would like to delete everything below that, until the last step, which is TUNNEL LIGHTS, OFF. So starting with “Before undocking only,” delete all lines through “TUNNEL VENT VALVE to TUNNEL VENT.”

Jack Swigert (CMP)
-
Okay. Delete the section that says “Before un-docking only” down to where it says “TUNNEL VENT VALVE to TUNNEL VENT.”
-
Vance Brand (CAPCOM)
-
Okay. Really what this does for you, then, is it gives you a pressure—a tunnel pressure integrity—or a hatch pressure integary—integrity check with a DELTA-P of 3 psi between the tunnel and the cabin. And then you never go on to the steps of venting that on out. You just leave it in there for the time that you separate from the LM. And that gives you a shotgun DELTA-V effect.
-
Vance Brand (CAPCOM)
-
Okay. I think that's all, but we're polling the house here to see if there's another comment for you. Stand by.
-
Vance Brand (CAPCOM)
-
Jack, that's it. Unless you have any more questions, why, everyone is hoping you'll hit the sack and get some rest.
-
Jack Swigert (CMP)
-
Okay. You want that battery backout procedure now to take that—to complete the remaining steps?
-
Vance Brand (CAPCOM)
-
That's affirm, Jack. We request that you go ahead and finish out the backout completely until you get to square 1. Over.
-
Vance Brand (CAPCOM)
-
We've still got a LM update, but we strongly recommend that you and Jack work as hard as you can sleeping for about the next 5 hours. Fred can handle it.
-
Jim Lovell (CDR)
-
Okay. That's what we'll do. We'll put Fred on watch here, and Jack and I will take it easy, and if Fred copies the LM update, well, then we'll all start from fresh in the morning.
-
Vance Brand (CAPCOM)
-
Okay, Fred. Two—three things. First thing is we need a docking angle check as soon as you can conveniently get it. Second point, you're free to drink all the descent stage water you want, if that wasn't clear before. And the third point, if you have a piece of paper, stand by to get writer's cramps. We have something to give you here.
-
Fred Haise (LMP)
-
Okay.

Fred Haise (LMP)

Okay. And your second item was, we can drink all of that descent waster that's left—looks like about 5 percent, and I'll get a book here and be ready to start writing.
-
Vance Brand (CAPCOM)
-
Okay. Get—This won't be as long as—as the one T. K. read up, but you'll need several pages, probably.
