Reentry.


Is a very brief portion of the total mission, not the total mission.
Without a SM, you'll never complete the mission and get to reenter.

I believe you said: "the CM is wedded always and forever to a SM."

Not only is this not true, but in fact there is a portion of *each and every
mission* in which, if it were true, it would lead to a loss of the vehicle
and crew.
