Yes. We can hear and feel the engine gimbal as we do the test.

Roger. Good —

FDAI SCALE —

— … relay cut in and TRIM is set.

FDAI SCALE, 5/5?

5/5.

RATE, HIGH and update the DET.

Time?

Let's check it.

Okay. We're coming up on 3 minutes. I'll give you a Mark.

Fair enough.

MARK.

Three minutes. DET is good.

Okay. We're set.

AS 58, we want DELTA-V THRUST A to NORMAL.

Jim, Houston. You're looking good down here. GO for the burn.

Right, Vance.

Okay. Two minutes. DELTA-V thrust —

DELTA-V THRUST A to NORMAL.

NORMAL.

TRANSLATION HAND CONTROLLER armed. Arm your ROTATIONAL HAND CONTROLLER. I've already got mine armed. Okay, Fred. TAPE RECORDER, HIGH BIT RATE, RECORD, FORWARD, COMMAND RESET. Standing by for 59.

It's running.

Minus 1 minute.

Okay …

AVERAGE G.

EMS mode to NORMAL.

MODE NORMAL.

Standing by for ENTER ENABLE.

ENTER ENABLE.

Two balls.

Okay. Shutdown.

…

Okay. Let's get the residuals. Okay, Houston, there are the residuals.

Okay; gimbal motors.

Okay. Copy residuals.

… secondaries.

Okay. Go.

Okay. YAW 2.

Good.

PITCH 2.

That's good.

Primary.

On LOW BIT RATE. Start. Go with the primaries.

Okay. YAW 1.

That's good.

PITCH 1.

Okay.

TVC SERVO POWER, OFF.

— is OFF. Okay. Record the DELTA-V_C. You got that?

Okay. You got the—You got the DELTA-V_C in minus 3.7.

Okay. FUNCTION, OFF. MODE STANDBY.

Proceeding now.

OFF. MODE, STANDBY —

TRANSLATION HAND CONTROL POWER, OFF.

Okay. POWER OFF.

ROT POWER DIRECT, two, OFF.

Two OFF.

RATE 2.

BMAGs, RATE 2.

I'm already in low bit rate.

Okay.

Yes, we were on those … so that we had less than 0.2.

Okay. Houston copied your residuals, very low.

Okay. Fuel is 1.0; oxidizer 0.25; the OX unbalance is reading on the decrease, which doesn't mean very much, and I guess that wasn't too much for a push there, Vance. I didn't see the accelerometer do a whole lot and it was a little surprising how slowly the injector valves opened, at least on the indicators.

Roger. That was a very short burn. Request you give us a sweep across the panel when you get a chance, Fred. Let us see Jack and Jim again. Over.

Okay.

Okay, Vance, I was going to show you on—wonder if the folks might—down there might be interested in how we find out how far we're away from the Moon. Going to do that right now in program 21 here.

Okay.

I'm asking the computer how far away we are. And the computer is telling me we're 121 490 miles out.

Okay. That agrees fairly closely with our map on the wall.

I'm glad. That means you're tracking us too.

And if you didn't see our residuals, it was 0.1 X, 0.2 on Y, and 0.1 Z, and DELTA-V_C was minus 3.8.

Jack, Houston. We show you down here 121 thousand miles 520 out. So I guess we all agree.

Okay. Real good, Vance. What I'm going to do is give you a shot of Fred.

If we can get all the wiring out of the way.
