Cooper dropped me off at Mercury Control and I was greeted by the familiar face of the only person in the program I knew down at the Cape, Paul Johnson, a troubleshooter working for Western Electric, one of the subcontractors to Bendix in building the control center and the tracking network. Western Electric's responsibilities included radars, telemetry (radio signals to and from the rocket and spacecraft that told us how things were working — and what wasn't) control consoles, and communications. These were the core systems. Western Electric quickly parlayed this into a responsibility for integrating operations, training, maintenance, and network communications. Paul was amazingly young for his responsibilities. He had an intuitive feel for this unprecedented development and deployment of technology, writing the specifications and testing procedures and doing everything that needed to be done to check out the largest "test range" in history, one that went around the globe."Kraft said you were coming down," he greeted me, smiling, "and I thought I'd give you a hand." During the next two days, Johnson gave me a master's degree in the art of mission control. He had been at the Cape for the preceding week and had been writing the manual on the team structure and operations. He handed it over to me to finish defining the standard operating procedures for Mercury Control, such as how to check out the console displays and communications, set the format for Teletype communications, and how specifically to request data from the technicians (politely but urgently).
I soon began to think of Paul as my guardian angel. From the moment I came on the job it seemed that whatever I was doing, wherever I turned, he was there. He always appeared when the pressure was on and I was happy to see him.
The day after I arrived Paul Johnson and I went to the launch pad. I was shocked when I first saw the Redstone rocket. It was stark, awkward, and crude, a large black-and-white stovepipe atop a simple cradle. It had none of the obvious coiled power and distinctive personality of an airplane; it was not graceful in form, not something you could come to love and rely on. The Mercury capsule squatted atop the rocket, black in color and seemingly constructed of corrugated sheet metal. With its tall red escape tower it looked more like a buoy in a harbor than a rocket ship from a science fiction novel. Given the oil fieldlike setting in the wilderness and the crude appearance of the rocket, I felt more like a drilling rig roughneck than a rocket scientist when I made my way into the bar of the Holiday Inn that evening.
By the end of the first week we had just finished the initial paperwork for the countdown procedures and mission rules, but had yet to run a simulated countdown. I was finally breathing easier. Johnson had taken me from Kraft's few words on what he wanted done to a point where I finally knew what he was talking about. It was only some six days after my "rocket ride" with Gordo Cooper, but my job was starting to seem real to me. The few days of hands-on familiarity with MCC systems now tied into the concept of the MCC team. The MCC was coming together as a working reality. My newfound knowledge, while only paper thin, was as good as anyone else's. It was now time to put it to the test. I called Kraft and said the countdown and the operational rules were ready.
Putting any reservations aside, I plunged into working with Paul on defining the joint tests of control and communications systems, as well as the Go NoGo points for telemetry display, command, and communications in Mercury Control. My next step was to synchronize the Mercury Control Center (MCC) countdown with the capsule and booster countdowns. Paul Johnson returned to Langley to deal with a set of problems in the tracking network while I completed the work down at the Cape. To this day I feel enormous gratitude to Paul for giving me a running start. This was one of the critical moments in my life when someone stepped in and pointed me in the right direction.
Given my aircraft test flight background, the control room felt vaguely familiar, with the exception of the three rows of consoles on elevated platforms. Each console was configured differently. Consoles on the top row were flat pedestals with communications boxes on top. When I first arrived at the Cape, Paul Johnson had taken me on a tour of the control room and pointed out the procedures console. I sat at the console, staring at the flat gray face and writing desk. The only instruments were a clock and an intercom panel with a rotary (!) phone at the top. This was the state-of-the-art work station that Paul and his colleagues from Western Electric had designed from scratch. It was on the left, in the middle row, and closest to the Teletype room. As I sat down at my console, two people came over and introduced themselves.
When Mercury-Atlas 1 exploded in flight, we fell about one year behind in the schedule, so a lot was riding on the first Mercury-Redstone flight, MR-1. Kraft's team arrived on November 13 for the MR-1 launch, now only eight days away. Once again my guardian angel, Johnson, arrived to save my bacon. He took a place to the right of the console and punched up the buttons of the intercom during our simulation dress rehearsal.
Immediately, a half dozen different conversations flooded through my headset. It reminded me of the cool, almost casual but terse and clear voice chatter that came up on the tactical frequency when things heated up during the time I was in Korea directing air strikes on ground targets. As I listened, I picked up the voices of the test conductors. Johnson broke out some thick documents and advised Kraft of the page and sequence of the countdown. It was fortunate that this was just a test. It gave Johnson a chance to brief me on the countdown process, get to know the people talking on the loops and Mercury Control's role in the test.
At intervals, Johnson encouraged me as the MCC procedures controller to make suggestions to Kraft or one of the other controllers. Throughout the test, he glanced around the room and made mental notes about what people at the various console positions should be doing or doing in a different way. Periodically, I would print out a message and call the ground communications controller. Eshelman would rush into the room to pick up the message, put it on the Teletype line, and then rush back with a confirming copy of the transmitted text. After several hours, I picked up the routine of the count and felt comfortable, as long as all was going well.
In Mercury Control the only controllers reporting administratively to Chris Kraft were the trajectory operators, Tecwyn (Tec) Roberts, and Carl Huss, whom I had yet to meet; Howard Kyle, who doubled for Kraft at the flight director console; Paul Johnson; and myself. The capsule engineers assigned to work with the MCC team understandably focused on hardware rather than flight operations and had their hands full checking out the spacecraft in Hangar S, and they looked at training in the Mercury Control Center as a waste of their time. The core of the engineering staff was based at Space Task Group headquarters at Langley Research Center. When McDonnell Aircraft sent a capsule to the Cape the engineers would come down and check it out in Hangar S.
Despite a certain amount of confusion about who should be doing what, since we were inventing it all as we went along, we were moving quickly to the crunch point. To my dismay, two days before launch at the readiness review, Johnson took me aside and said he would not be there. He had to go to the Canary Islands to work out a tracking site problem. He wished me good luck.
Only one month and four days after I was hired, I was at the procedures console. Thanks to Johnson's unflagging coaching and the training we had done, I had no problems and felt comfortable with the mechanics. But I had a long way to go before I would have that sense of "being ahead of the airplane" or "ahead of the power curve" as pilots put it — having the experience to anticipate what could happen rather than just reacting to what was happening at the moment.
