At a little after 1 a.m. I got up, shaved and showered and had breakfast with John Glenn and Bill Douglas. John was most kind. He asked me if there was anything he could do, wished me well and went on down to the capsule to get it ready for me. The medical exam and the dressing went according to schedule. There were butterflies in my stomach again, but I did not feel that I was coming apart or that things were getting ahead of me. The adrenalin was pumping, but my blood pressure and pulse rate were not unusually high. A little after 4 a.m., we left the hangar and got started for the pad. Gus and Bill Douglas were with me.
They appeared to be a little behind in the count when we reached the pad. Apparently the crews were taking all the time they could and being extra careful with the preparations. Gordon Cooper, who was stationed in the blockhouse that morning, came in to give me a final weather briefing and to tell me about the exact position of the recovery ships. He said the weathermen were predicting three-foot waves and 8–10 knot winds in the landing area, which was within our limits. Everything was working fine.
Shortly after 5 a.m., some two hours before lift-off was scheduled, I asked if I could leave the transfer van. I wanted some extra time to have a word with the launch crews and to check over the Redstone and the capsule, to sort of kick the tyres – the way you do with a new car or an airplane. I realized that I would probably never see that missile again. I really enjoy looking at a bird that is getting ready to go. It’s a lovely sight. The Redstone with the Mercury capsule and escape tower on top of it is a particularly good-looking combination, long and slender. And this one had a decided air of expectancy about it. It stood there full of lox, venting white clouds and rolling frost down the side. In the glow of the searchlight it was really beautiful.
After admiring the bird, I went up the elevator and walked across the narrow platform to the capsule. On the way up, Bill Douglas solemnly handed me a box of crayons. They came from Sam Beddingfield, he said. Sam is a NASA engineer who has developed a real knack for helping us to relax, and I appreciated the joke. It had to do with another, fictional, astronaut, who discovered just before he was about to be launched on a long and harrowing mission that he had brought along his colouring book to kill time but had forgotten his crayons. The guy refused to get into the capsule until someone went back to the hangar and got him some.
I walked around a bit, talking briefly with Gus again and with John Glenn. I especially wanted to thank John for all the hard work he had done as my backup pilot. Some of the crew looked a little tense up there, but none of the astronauts showed it.
At 5:20 I disconnected the hose which led to my portable air-conditioner, slipped off the protective galoshes that had covered my boots and squeezed through the hatch. I linked the suit up with the capsule oxygen system, checked the straps which held me tight in the couch, removed the safety pins which kept some of the switches from being pushed or pulled inadvertently and passed them outside.
John had left a little note on the instrument panel, where no one else could see it but me. It read, NO HAND BALL PLAYING IN THIS AREA. I was going to leave it there, but when John saw me laugh behind the visor he grinned and reached in to retrieve it. I guess he remembered that the capsule cameras might pick up that message, and he lost his nerve. No one could speak to me now, face-to-face. I had closed the visor and was hooked up with the intercom system. Several people stuck their heads in to take a last-minute look around, and hands kept reaching in to make little adjustments. Then, at 6:10, the hatch went on and I was alone. I watched as the latches turned to make sure they were tight.
This was the big moment, and I had thought about it a lot. The butterflies were pretty strong now. “OK, Buster,” I said to myself, “you volunteered for this thing. Now it’s up to you to do it.” There was no question in my mind now that we were going – unless some serious malfunction occurred. I had anticipated the nervousness I felt, and I had made plans to counteract it by plunging into my pilot preparations. There were plenty of things to do to keep me busy, and the tension slackened off immediately. I went through all the checklists, checked the radio systems and the gyro switches.
