Neil Armstrong (CDR)

And that time we got an onboard indication, Houston. Thank you a lot.

Bruce McCandless (CAPCOM)

Roger. We confirm that it is OFF.

Michael Collins (CMP)

Houston, Apollo 11. We're starting our maneuver to observe the S-IVB slingshot.

Bruce McCandless (CAPCOM)

Roger, 11. We've got an updated attitude for you on the slingshot observation.

Michael Collins (CMP)

Okay. Say the angles please.

Bruce McCandless (CAPCOM)

Roger. Roll 002.5, pitch 289.3, yaw 357.5, and there's also an update—minor correction to your attitude for the P52. Over.

Michael Collins (CMP)

Roger. I have roll 002.5, pitch 289.3, and yaw 357.5. Over.

Bruce McCandless (CAPCOM)

Roger. And for your P52 and optics calibration, it'll be roll 346.5, pitch 345.0, and yaw 007.8. Over.

Michael Collins (CMP)

Roger. 346.5, 345.0, and 007.8. Thank you.

Bruce McCandless (CAPCOM)

Apollo 11, this is Houston. Over.

Michael Collins (CMP)

Roger. Go ahead, Houston. Apollo 11.

Bruce McCandless (CAPCOM)

Roger. We're going to go ahead and enable the S-IVB for the slingshot maneuver. The LOX dump will start about 12 minutes from now. Over.

Michael Collins (CMP)

Okay, LOX dump about—I guess that'll make it about 01, huh?

Bruce McCandless (CAPCOM)

Right. I'll try to give you a little closer update as we approach it.

Bruce McCandless (CAPCOM)

And, 11, for you information, the magnitude of midcourse correction number 1, if we burn, looks like about 17 feet per second. We're presently considering not burning it. This would make midcourse correction 2 tomorrow about 21.3. Over.

Bruce McCandless (CAPCOM)

Roger. You're looking good down here.

Neil Armstrong (CDR)

Well, we didn't have much time, Houston, to talk to you about our views out the window when we were preparing for LM ejection; but up to that time, we had the entire northern part of the lighted hemisphere visible including North America, North Atlantic, and Europe and Northern Africa. We could see that the weather was good all—just about everywhere. There was one cyclonic depression in Northern Canada, in the Athabaska—probably east of Athabaska area. Greenland was clear, and it appeared to be we were seeing just the icecap in Greenland. All North Atlantic was pretty good; and Europe and Northern Africa seemed to be clear. Most of the United States was clear. There was a low—looked like a front stretching from the center of the country up across north of the Great Lakes and into Newfoundland.

Michael Collins (CMP)

I didn't know what I was looking at, but I sure did like it.

Bruce McCandless (CAPCOM)

Okay. I guess the view must be pretty good from up there. We show you just roughly somewhere around 19,000 miles out now.

Michael Collins (CMP)

I didn't have much outside my window.

Bruce McCandless (CAPCOM)

We'll get you into the PTC one of these days, and you take turns looking.

Michael Collins (CMP)

Houston, Apollo 11. We've completed our maneuver to, observe the slingshot attitude, but we don't see anything—no Earth and no S-IVB.

Bruce McCandless (CAPCOM)

Roger. Stand by. In GET I have a LOX dump start time for you. It's supposed to start at 5 plus 03 plus 07, and stop at 5 plus 04 plus 55. Ullage burn starts at 5 plus 37 plus 47, stops at 5 plus 42 plus 27. Over.

Bruce McCandless (CAPCOM)

Roger. We now recommend the following attitude: roll 307.0, pitch 354.0, yaw 019.5, and the LOX dump has already been enabled, so we can't hold it off any longer.

Michael Collins (CMP)

That's okay. Go ahead. We'll maneuver around to 307, 354, and 19 and a half. Thank you sir.

Bruce McCandless (CAPCOM)

11, Houston. It doesn't look to us like you'll be able to make it around to this observation attitude in 2 minutes. We recommend that you save the fuel. Over.

Michael Collins (CMP)

Okay, Houston. You got to us just a little late. Our maneuver's already begun, so it's going to cost us about the same amount of fuel to stop it, no matter where we stop it, and we may as well keep going.

Bruce McCandless (CAPCOM)

11, Houston. LOX dump initiated.

Bruce McCandless (CAPCOM)

11, Houston. LOX dump has been terminated. Over.

Buzz Aldrin (LMP)

Roger. We still don't have …

Bruce McCandless (CAPCOM)

Apollo 11, this is Houston. Over.

Bruce McCandless (CAPCOM)

Roger. If you'll give us ACCEPT and stay in P00, we'll set your trunnion bias to zero. And, I have a plan for balancing your oxygen CRYO's. Over.

Buzz Aldrin (LMP)

Houston, Apollo 11. We've got the—what appears to be the S-IVB in sight—at—oh, I'd estimate a couple of miles away. It's at our number 5 window and the dump appears to be coming out of two radially opposite directions from the S-IVB.

Bruce McCandless (CAPCOM)

Roger. They're continuing with the nonpropulsion vent from the liquid oxygen tank. It would be radially opposite, then. And boosters tell me it's the continuous vent system. They're also dumping a small amount of fuel at this time. We've got about 23-1/2 minutes or so until the APS burn. Over.
