* Armstrong didn't just land the Eagle, he "coolly accelerated" it, emphasizing the skill and precision required for the landing. This could be a way of highlighting the daring and expertise of the mission.
* "Hovering" implies a sense of control and mastery over the situation. It emphasizes that Armstrong wasn't just blindly descending but was carefully maneuvering the lunar module.
Overall, the phrase is likely meant to be a humorous and slightly irreverent take on the historic moment, emphasizing the control and skill involved in the lunar landing.
