For the Apollo missions that left Earth orbit, were there multiple recovery zones for each splashdown? How big was each zone?

    $\begingroup$ I don't know how big the designated recovery zones actually were, but they didn't need to be very big in practice: each of the lunar Apollo flights landed within 3 nautical miles of their targeted location, none of them more than 13 nautical miles from the recovery ship. history.nasa.gov/SP-4029.pdf $\endgroup$ – Russell Borogove Dec 12 '18 at 19:01

    $\begingroup$ Even Apollo 13 did a very precise splashdown. "The impact point was about 1.0 n mi from the target point and 3.5 n mi from the recovery ship U.S.S. Iwo lima." To save time on return "A 263.82-second transearth injection maneuver using the LM descent propulsion system was executed at 079:27:38.95 to speed up the return to Earth by 860.5 ft/sec after the docked spacecraft had swung around the far side of the Moon" Amazing precision despite a mission abort and a modified return trajectory. Cites from Apollo by the Numbers. $\endgroup$ – Uwe Dec 12 '18 at 21:53
