This is Volume I of III of the Gemini VII voice communications transcript, covering pages 1 to 337 and marked Confidential. It records air-to-ground, ground-to-air and on-board exchanges beginning at lift-off. Early passages cover staging, orbit insertion and stationkeeping with the booster, which the crew reports is venting heavily, and they photograph it. Later passages near 116 hours hold the crew's detailed descriptions of airglow, stars and a sunrise seen from orbit.

# CONFIDENTIAL 20:51:54 CC Okay. Here's a little rundown on what we think the situation is on that light. Can you give us a quantity readout on the fuel cell hydrogen and oxygen? Just give us the switch position for each one. We'll read them out here on the ground. 20:52:13 P Roger. Fuel cell oxygen now. 20:52:16 CC Roger. Okay. Give us the other one. 20:52:25 P Fuel cell hydrogen. 20:52:27 CC Roger. 20:52:32 CC Okay. Brief discussion here on fuel cell light as we can see it. We think the most likely reason is an accumulation of tolerances of the Delta-P light transducer and the regulator, plus a pressure difference between the water reference to the regulator and the Delta-P switch. In other words, just an accumulation of tolerances here, which is giving us a light that is really not indicative of the true condition. 20:53:03 C Roger. Thank you. It's not much help I guess, but that's what we think is the most likely thing. Rundown on other possibilities. The next most likely thing, we think, is a defective Delta-P switch. The third possibility is a water valve closed or some restriction in the water line, and that would pose a problem, but we feel that we can handle that even if it means shutting down that fuel cell, and we feel this will be indicated by a deterioration in the performance of that fuel cell over many hours. We'll be able to watch that build up. It won't pose any hazardous condition at all. And the last possibility is a regulator which is slightly out of tolerance. We think the latter two things here now are not very high probability, but they are possibilities. Do you have any other items or suggestions? 20:54:09 C Negative. 20:54:12 CC Okay. Do you have a water reading handy for us at this time, Gemini VII? CONFIDENTIAL
