What I immediately noticed was how calm and controlled the team at Mission Control were. Messages were flying around yet the system worked as everyone concentrated on their particular aspect of the mission and things only went up the 'pyramid' to the Flight Controller if he really needed to know something. The other essential part of all this was that only one person communicated with Eagle and this wasn't the Flight Controller, it was CapCom. This meant that Armstrong and Aldrin could concentrate on the matter in hand, landing the LEM.
The system was well designed and it worked well thanks to a good team and the right man at the helm.
