Gus Grissom

Well, get it in!

John Young

96?

John Young

I'm in Catch-Up mode.

Gus Grissom

Says to put in 2590960.

Gus Grissom

You have about 2 minutes.

Gus Grissom

2—5—9—0—9—6—0

John Young

Okay, but — that's what we're going to shoot for.

John Young

Okay. At the start of this we'll be about 52 percent.

Gus Grissom

Man! I mean we start to burn just as we come over there.

John Young

Let's go ahead and hit the Catch-Up thing and see what it says.

John Young

Well, let's do it — put it back in. Okay. Now try it.

Gus Grissom

There she goes. 6—5—4 — how did it get in there? My attitudes are not 0, 0, 180.

Gus Grissom

The IVI's keep counting up, though.

John Young

It does keep changing, doesn't it?

Hawaii CapCom

Hello, Molly Brown. Hawaii CAP COM.

Gus Grissom

Hawaii, Molly Brown is all ready for burn.

Hawaii CapCom

Roger. Give us a hack on your event timer.

Gus Grissom

Okay, it'll be 12:55 on my mark.

Gus Grissom

MARK.

Hawaii CapCom

Right, we are right on.

Gus Grissom

Okay. On my IVI's, I have 97 ft/sec forward and the others are zips.

Hawaii CapCom

Roger, and give us a mark for the start of burn.

Gus Grissom

Roger. We've got about 25 seconds to go.

Hawaii CapCom

Roger.

John Young

That's perfect out-the-window alinement.

Gus Grissom

We have 50 percent propellant quantity indicated. Getting ready to fire —

Gus Grissom

Key moment Third orbital maneuvre, lowering perigee to enable re-entry even if the retrorockets failed: MARK!

Hawaii CapCom

We got your start of burn.

Gus Grissom

Yes, it's burning.

Gus Grissom

You know, you can't hear those big thrusters.

John Young

There's a minute of burn.

John Young

4—3—2—1 -

Hawaii CapCom

Right. Mark end of burn. Good show.

John Young

We timed that a minute and 48 seconds.

Hawaii CapCom

Give us your IVI readings.

Gus Grissom

IVI's: Fore-Aft 0, Left was 1, Up was 2.

Gus Grissom

That was the end of burn.

Hawaii CapCom

Okay, and how did your attitudes look?

Gus Grissom

Attitudes were right on, plus or minus 2 or 3°.

Hawaii CapCom

Okay, they look good on the ground.

Gus Grissom

Now we can go to REENTRY. Right?

John Young

Okay, I've got 9:29 on the TR.

Gus Grissom

Oh! Give me another.

Gus Grissom

I'll give you one at 19. Okay?

John Young

Okay, and the propellant source pressure is 1500.

Gus Grissom

We had indicated 22 percent when we got done, Neil.

Hawaii CapCom

20 percent. Rog?

Hawaii CapCom

Okay.

John Young

Source pressure is 1500, source temperature 60-50, I mean. And the RCS-both rings on. Antenna okay. On REENTRY. Heaters off. Quantity Read Switch off.

Gus Grissom

Let's see, did we get all of this?

John Young

OAMS power to ATTITUDE, controller stow, attitude PULSE, computer to REENTRY.

Gus Grissom

Now we're lined up good.

John Young

Okay, and the retro load is initialized now, because I called addresses 10 and 11 out of the computer.

Gus Grissom

Now, don't go out of Reentry mode.

John Young

Okay, but I don't think it would make any difference, as long as we go back. Okay — platform — rate — computer to REENTRY — RATE COMMAND — roll gyro off.

John Young

Platform is ORBITAL RATE — No.

John Young

Retro power—ARM.

Gus Grissom

Not now. At TR-5, you mean?

John Young

Well, this is the 5-minute checklist.

Gus Grissom

Okay, well, we'll just — 7:20 now.

Gus Grissom

I haven't heard any of those squib isolation pyros fire yet. Have you?

John Young

Yes, I heard the ones on the pad fire.

Gus Grissom

Did you? I don't remember, I guess.

John Young

I was listening for all that jazz.
