Affirmative. Area 3 Echo, Area 3 Echo is 4 hours, 22 minutes, 12 seconds. I say again; 4 hours, 22 minutes, 12 seconds. Over.

Roger. Area Hotel is 4 hours, 32 minutes, 37 seconds. Say it again; 4 hours, 32 minutes 37 seconds. Over.
- John Glenn
-
Roger. 04 plus 32 plus 38. I have correction, plus 37; I have 38 set on my retrosequence because of error in my clock of 1 second. Over.
- John Glenn
-
One second error, that is affirm. Request you confirm with Cape that I have 04 plus 32 plus 38 as correct retrograde time. Over.

This is Friendship Seven. The ASCS is drifting again. I'm indicating 25° right in yaw. Over.
- John Glenn
-
This is Friendship Seven. I have almost continuous cloud cover under me as far as I can see in every direction. Over.
- Flight Surgeon
-
This is the surgeon here. Have you switched to secondary oxygen for any reason during this hop? Over.
- John Glenn
-
Negative. I don't quite understand the decrease in secondary either unless it's the bottles are beginning to cool down, but they shouldn't cool that much.
- John Glenn
-
Roger. This is Friendship Seven. This thing is slipping in and out of orientation mode and wasting fuel at present time. I'm just going to try and hold it on orbit attitude manually. Over. Or on fly-by-wire. Over.
- John Glenn
-
This is Friendship Seven. Checking different control modes on fly-by-wire. I have no low thrust to the right. Over.
- John Glenn
-
This is Friendship Seven. Affirmative. I have Orion right in the middle of the window at present time and makes a good one to hold attitude on. I have, I am using it as horizon reference at the moment.
- Comm Tech
-
Friendship Seven, this is Muchea Com Tech. How do you read? Over.

Hello, Muchea Com Tech. Loud and clear. Standby one. I'm right in the middle of operation here.

Hello, Muchea Com Tech, Muchea Com Tech. Roger. Friendship Seven. Loud and clear. How me?
- John Glenn
-
Roger. Hello Cap Com, Friendship Seven. How are things going?
Expand selection down Contract selection up - John Glenn

Roger. This is Friendship Seven. 30-minute report: ASCS is major item, still not operating properly. I am on fly-by-wire at present time. I have no low thrust to the right fly-by-wire. Over.
- John Glenn
-
This is Friendship Seven. In 45 more seconds I would like to have you send a message for me, please. Over.
- John Glenn
-
I want you to send a message to the Director, to the Commandant, U.S. Marine Corps, Washington. Tell him I have my 4 hours required flight time in for the month and request flight chit be established for me. Over.
- John Glenn
-
Yes, all the fuse switches are still in the same position, Gordo. I haven't changed any of those. Squib is armed, Auto Retrojettison is off. I am on fly-by-wire, auto, and gyro normal. All “T” handles are in. The sequence panel is normal except for Landing Bag in the off position. The attitude indicator has been rather erratic, they drift very rapidly sometimes. Especially when I maneuver myself and then come back onto ASCS. It seems they have been thrown way off at that time.
- John Glenn
-
My retrograde time 04 plus 32 plus 38 for capsule time which corrects for I second error in this clock.
- CAPCOM
-
On that, MCC recommends you change that to 04 32 37 shortly after you get done with these others.
- John Glenn

Roger. Okay, cabin pressure is still holding at 5.5. It's been there ever since we left. 90 [percent] on cabin temp, relative humidity is back up again now to about 36 [percent], coolant quantity is down a little bit too, we may have had a small water leak some place since we have that much increase in humidity, cause it was down around 20 [percent]. Our coolant quantity, though, is down around 62 [percent] now. The suit temperature is 70 [degrees] inlet; cabin suit pressure is 5.8. Steam temperature is 4 point, is 48 [degrees]. Oxygen is 60-90 [percent]. Amps are 24, ASCS is 11, about 115 now. Fan, is 110. Over.
- John Glenn
-
That's affirmative. On the right side, everything is outboard except the fuel quantity warning light which is on. I have that switch inboard to cut the audio.
- John Glenn
-
The only 2 switch fuses in the center off position, on the right, are Retro Jettison and Retro Manual. Over.
- John Glenn
-
Water on, on cabin temperature is setting number 2. Setting on the suit temp is beyond the 1.7 mark. I repeat, beyond the 1.7 mark which is the maximum setting.
- John Glenn
-
Well, I don't know. I want to start lining up just as carefully as I can here in a minute and see whether the scanners will pick it up and correct it in so that we have a good retrofire attitude. If it is not, I'll aline it myself. Over.
- CAPCOM
-
And, now I gave you the recommended change in the retro clock to 04 32 37. On your retro, using ASCS, you'll be using high torque thrusters for retrofire mode there. What do you say about retroing by ASCS and backing up by fly-by-wire?
- John Glenn
-
Yes. If the ASCS appears to be programing and holding a good orbit attitude I'll let it go on ASCS and back it up with manual. If not, if it appears that the gyros are cocked as they were a little while ago, then I'll just stay on manual retrofire, I think and let it go at that.
