Unidentified crew member

Michael Collins (CMP)

Houston, Apollo 11. Checklist page F9 7; I've completed step 8, and I'd like to know what you think is ideal timing between step 8, step 9, and step 10 on that page? Over.

Charlie Duke (CAPCOM)

Apollo 11, Houston. We don't see any time constraint. We'd like you to go ahead and set up the wide deadband and then go through step 10 and 11. Over.

Michael Collins (CMP)

Okay. Will do. I don't see any constraint here, Charlie. I was just checking to make sure, because last time, I went from 8 to 9 to 10 to 11 a little bit more swiftly than I'd been doing in the past.

Charlie Duke (CAPCOM)

Apollo 11, Houston. Would you please select OMNI Bravo? Over.

Michael Collins (CMP)

Houston, Apollo 11. How do you read on Bravo?

Charlie Duke (CAPCOM)

Roger. Reading you five-by.

Charlie Duke (CAPCOM)

Apollo 11, Houston. Looks like we've got a good PTC going. It's good night from the White Team. Over.

Michael Collins (CMP)

Okay. See you tomorrow. Thank you for everything.

Neil Armstrong (CDR)

Do you have any idea where the S IVB is with respect to us?

Charlie Duke (CAPCOM)

Apollo 11, Houston. The S IVB is about 6000 nautical miles from you now. Over.

Michael Collins (CMP)

Houston, Apollo 11. How's the PTC looking?

Charlie Duke (CAPCOM)

11, Houston. The PTC looks great to us. Over.

Michael Collins (CMP)

Hey, do you have any idea what happened to the previous one?

Charlie Duke (CAPCOM)

We have absolutely no idea. Over.

Michael Collins (CMP)

Okay. Did, it look like it was all right, then just all of a sudden start diverging?

Charlie Duke (CAPCOM)

That's negative, Mike. If you'll look at the plot, which we'll save for you and let you see it postflight, it started off immediately on the first REV and just spiraled out to about—oh 20 to—20 degrees in pitch, and then it seemed to be setting up a spiral around an offset pitch point of about 20 degrees off from 90 degrees; but we didn't want to take a chance that it would become stable at that point. We thought it might diverge, and so we called you and started over again. Over.

Michael Collins (CMP)

Okay, no complaints. I was just curious as to what had happened.

Hello, Houston. Apollo 11.

Apollo 11, Houston. Good morning.

Buzz Aldrin (LMP)

Good morning. Are you planning a midcourse correction 4 this morning?

Ronald Evans (CAPCOM)

That's negative. Midcourse number 4 is not required. We were going to let you sleep in until about 71 hours if you'd like to turn over.

Buzz Aldrin (LMP)

Okay. That'll be fine.

Ronald Evans (CAPCOM)

Say again, Buzz. You were cut off there.
