That was O2 High Rate for about two minutes to bring the pressure off the peg. it's now reading 985, and cabin pressure is holding at 5.6.

I know you shouldn't let those things float around, but I don't know what to do with them.
- Gus Grissom

Looks like the velocity is about perfect. You can really tell you're moving on. You know that?
- John Young
-
Okay. That's what we want to burn. I've got to change this tape cartridge. The camera is set for f11 at 250.

The oxygen pressure has climbed right up back there off-scale.

Roger. Read you loud and clear. I'm going to update your TR and transmit a maneuver load to you.
- Gus Grissom
-
Our status is GO. We did bring the ECS O2 back down on the scale with O2 High Rate, and since that time it has returned to off-scale.

Roger, and I have transmitted a TR and Gemini load for your maneuver over Corpus. Confirm you were in CATCH-UP. Over.
- RKV CapCom
-
Roger. You have a load in the CATCH-UP for your maneuver.
- Gus Grissom
-
Got to be in CATCH-UP.

Roger. Your GMTB…correction, 15 57 00. Your ground elapsed time to burn, 01 33 00. Your ΔV of the burn, 048. Your length of burn, 01:14.

Molly Brown, can you give me a readout of your OAMS helium source pressure, temperature, and your propellant quantity gage.
- John Young
-
Roger. Source pressure is 2450. Source temperature is 85°, and fuel and oxidizer regulated at 295 with 68°.
- Gus Grissom
-
Roger. We're in good shape.

Molly Brown, RKV. I'm getting an indication of OAMS thrust forward-firing. I have negative OAMS yaw firing on the ground.
- Gus Grissom
-
We're not doing any firing. We're not even in MANEUVER and ATTITUDE and we haven't touched the handle.
- Gus Grissom
-
Okay. It will be about two minutes before we start it. So you punch off your stopwatch and tell me — give me a mark to stop it—just in case it doesn't go to zero.
- John Young
-
Yes, but it should have been 48. I don't know why it came out to 50. Should we bring it down to 48?
