Default Apollo Splashdown Locations

I've noticed that all of the Apollo splashdown locations were located
between +/- 30 degrees in latitude, which happens to correspond to the
moon's orbital inclination for the Apollo era.

Is there some aspect of orbital mechanics that limits direct reentry landing
locations to values between the orbital inclination, or were the Apollo
spalshdown locations chosen for other reasons?

TIA

Has Luna's orbit changed since then???

Aiui, to reach a higher latitude than the orbital inclination requires fuel
burn, which there was no reason for. There may have been other reasons.

it was designed for emergenmcy landing on ground. the bottom of the capsule
would of crushed.

Apollo capsules were designed to take a ground landing - it certainly
wouldn't have been comfortable, but it was in the design specs.

(Remember that they were launching from the coast; a pad abort could
well mean the capsule came down on land, dependent on the wind levels,
so it had to be designed for)

....Nah, one of the crew would have found this bottle, and from that
moment on the fate of anyone against NASA would have been rather bleek
at best :-)

Generally speaking, yes: those are the locations that the orbit (and
thus, any other orbit in the same plane) passes directly over. Landing
elsewhere would require a plane change at some point, which is generally
costly and pointless.

The Moon's orbit, including its inclination, actually *does* change over
time... within limits. The Moon's motion is extremely complex and can't
be modeled for any great length of time as a classical two-body system.
Earth's non-spherical shape and the Sun both get into the act.

On the other hand, weren't the canards and side-thrust rocket on the
escape tower aligned to take the capsule out to sea if they did abort on
the pad?
