What maneuver was essential for achieving the record-setting return speed of Apollo 10?
Answer
A trajectory maximizing the gravitational pull of the Moon
The high velocity was a direct result of executing a calculated 'free-return trajectory' that utilized the Moon's gravity to sling the spacecraft back toward Earth with maximum efficiency.
