1. Located at Johnson Space Center in Houston, Texas, the heart of mission control was the Mission Operations Control Room, or MOCR (pronounced mo-cur). "I had the privilege of being present in the MOCR as two astronauts made the first landing" on the moon.

2. The big screens at the front used a rear-projection system that was half the size of the MOCR itself. "There was always some guy back there in the dark making sure it was working."

3. The controllers in charge of Apollo spacecraft systems sat in the second row. As an EECOM, Liebergot watched over electrical systems here.

4. The front row of the MOCR was dubbed "the Trench." It was where the controllers in charge of navigation and guidance sat. "They had their own matchbook and business cards, and they called us a bunch of plumbers and electricians. We demeaned them by saying 'all you guys do is watch trajectory plots.'"

5. Behind this window sat simulation conductors. "They read all [the flight controllers"] procedures, and then they devised training scripts to test us. Some of them took a lot of pleasure in trapping us, but the simulations were invaluable."

6. Mission control's consoles had handles for easier servicing, but controllers knew them as "security handles. They were something to grab onto in times of tension. You grab one handle, you got a problem. Grab two handles--you got a real big problem."

7. The rear of mission control was known as "management row" because senior NASA staff would sit there. The rest of the room was an alphabet soup of positions that watched over every aspect of the mission.
