The machine-like performance of flight crew and ground controllers continued. Each participant was in perfect harmony with the other, moving to a cadence dictated by the laws of physics and the clock.
As they passed behind the moon, they had just over 8 minutes to go before the burn. They were super-careful now, they checked and rechecked each step several times. It had to be perfect.
