This is Friendship Seven. The sun coming through the window is very warm where it hits the suit. I get quite a bit of heat from it.
- John Glenn
-
This is Friendship Seven. Negative, not at present time. I am going to start into a yaw right very shortly. Over.
- John Glenn
-
That is affirmative. At one time, I had no left low thrust in yaw, now that one is working, and I now have no low right thrust in yaw. Over.
- John Glenn
-
This is Friendship Seven. Have yawed 165 [degrees], holding orbit attitude in roll and pitch. Over.
- John Glenn
-
This is Friendship Seven. I like this attitude very much, so you can see where you're going. Over.
- CAPCOM
-
Friendship Seven, this is Kano. Any time you're ready, we'd like your status report. We hear you loud and clear, also.
- John Glenn
-
Roger, Kano. This is Friendship Seven. I am presently returning to orbit attitude from 180° yaw check. Over.
- CAPCOM
-
Roger, Friendship Seven. We marked that your part of the transmission pretty clearly over ATS, and understand you like the old attitude.
- John Glenn

Roger, Friendship Seven. We are monitoring your inverters. Your 150-volt inverter 200°, your 250, 180°-180°.
- CAPCOM
-
Friendship Seven, we have telemetry solid and check all your systems out okay. We will remind you to start pre-darkside check list as soon as you lose contact with us.
- John Glenn
-
This is Friendship Seven. I now have control in low thrust to the left. I do not have control in low right thrust. Over.
- CAPCOM
-
Roger. Confirm you have control in low thrust to the left, but no control in low thrust to right.
- John Glenn
-
Negative. Friendship Seven. I'm in orbit attitude. I'll try and go back on ASCS and see if it works. Over.
- John Glenn
-
This is Friendship Seven. The capsule appears to be holding in ASCS okay, but I believe we are off in yaw. Do you confirm? Over.
- John Glenn
-
This is Friendship Seven. I'm going to depart from flight plan for a moment and try and work this out a little better here, we are drifting in yaw. I am cutting automatic yaw off. And, and will control manually in yaw temporarily. Over.

Friendship Seven, this is Zanzibar Cap Com, reading you weak but readable. We have solid telemetry contact. Report your status. Over.
- John Glenn
-
Roger. This is Friendship Seven. My status: I am on ASCS, it is not holding all the time. My trouble in yaw has reversed. During the first part of the flight, when I had trouble over the west coast of the United States, I had a problem with the yaw, with no low thrust to the left; now I have thrust in that direction but do not have low thrust to the right. When the capsule drifts out in that area, it hits high thrust and drops into orientation mode, temporarily. Over.
- CAPCOM
-
Roger, Friendship Seven. This is Zanzibar Cap Com. Continue with your 30-minute report. Over.
- John Glenn
-
Roger. This is Friendship Seven. Thirty-minute report follows: Head movements cause no nausea or no bad feelings at all. I am surprised that I can look as close to the sun as I can; the sun is shining directly on my face at present time, and all I have to do is to shade my eyes with my eyebrow. All fuse switches are still as previously reported on left panel. ASCS Mode Select is normal, auto, gyro normal: Squib is armed, Auto Retrojettison is off. All “T” handles are in except manual and I have it pulled so that I can immediately go to manual as a backup in case the ASCS malfunctions further. The Rescue Aids are normal. Landing bag is off. All other sequence panel items are in normal position. Control fuel is 68-100 [percent], repeat, 68-100. EPI is indicating my approximate position. Time from launch is 02 plus 06 plus 30 MARK. Retrograde time for [area] H is still set for 04 plus 32 plus 28. I would like to know if Canaveral wants me to reset that into the clock. Over.

Negative, I am on manual at present time. I'm down to 60 [percent] on automatic fuel, so I cut it off and I'm on manual at present time. Over.
- John Glenn
-
This is Friendship Seven. I am getting some erratic indications in all axes. When I align everything on orbit attitude by the instruments I am considerably off where I should be. I'm rolled some 20° to the right; I'm also yawed to the right a little bit. Over.
- CAPCOM
-
Roger, understand. Are you satisfied with the fly-by-wire and manual proportional systems? Over.
- John Glenn
-
That's affirmative. When I first had trouble with it, it was malfunctioning in low yaw left, and now low yaw left is operating okay, but low yaw right is not operating. Over.
- CAPCOM
-
Roger. Have you tried caging your gyros and re-erecting them. What do you think about this? Over.
- John Glenn
-
Negative, have not yet. I want to get an alignment as soon as I get back in daylight and do just exactly that. I think my, I'm probably not—my scanners are probably not working right. Over.
- CAPCOM
-
They wanted this answer. Do you have your retrosequence times 2 Dog, Easy, and Golf from Indian Ocean Ship?
- John Glenn
-
Negative, I have no ill effects whatsoever. I don't even really notice it now. I'm just, very comfortable.
- John Glenn

Cape advises that you conduct this horizon check, and cage the gyros before California contact. Over.
- CAPCOM
-
Roger. Would like to confirm your control systems status, fly-by-wire low yaw right is inoperative.
- John Glenn
-
This is Friendship Seven. ASCS started out operating, it would drop into orientation mode in yaw and that would throw the other axes out. It was doing this for a while it world drift off slowly, yaw right and there would be no correction until it went out about 20° . Then it would come rapidly back across and correct itself from a 20° right attitude, would come back across to a left attitude in orientation mode. This continued for a while. I took control, that was right after Guaymas. By the time I had gone over Africa the condition had just reversed, had just reversed. The same thing, only the other direction. Over.

Roger, Friendship Seven. Are, are your thrusters working, are all your high thrusters working okay. Over.
- John Glenn
-
This is Friendship Seven. I think my, I can see a little bit of steam spitting against the dark sky here occasionally from my pitch down manual thruster. Over.
- John Glenn
-
This is Friendship Seven. All these little particles; there are thousands of them; and they're not coming from the capsule. They're something that's already up there because they're all over the sky. Way out I can see them, as far as I can see in each direction almost.
- CAPCOM

Friendship Seven, I have no sensations at all from weightlessness except very pleasant. No ill effects at all, I'm not sick; feel fine. I have had no, no dizziness: I've run the head checks, the head movements and have no problem with that. I've run the oculogyric check and have no problem with that. I haven't been able to use much of the equipment this orbit, however. I've been mainly concerned with this control problem. Over.
