Married Couples and CRM (followon to Courious Crash)

What I am trying to understand is, how a husband and wife, both pilots,
would not challenge their spouse's decision to press a situation which
might lead to an uncertain outcome?

(Taking this thread into a new direction)
Ron and Margie, Jay and Mary, and the Tcraft couple are the only married
couples who use this forum that I am aware of.
Maybe there is a new thread, do spouses that fly together use a
challenge
and response type of CRM when they fly together?
What type of resolution do they use?
If either one or the other expresses a concern, do they land and sort it
out?
Does one or the other have overriding veto?


Just some anecdotal info:

At the AOPA Expo, John and Martha King (arguably the best known
Husband/Wife
flying duo) mentioned that this was at one time a huge problem for them.
As
they tell it, after many arguments and disagreements (and you get the
sense
that some affected their flying) they came up with a pretty simple
solution:
The person in the right seat calls the person in the left seat "Captain"
which immediately difuses any question as to who is PIC.

Now, they go on to explain in their presentation that they have forged CRM
meathods that work specifically for them. The biggest one is that they
have
learned to make their point(s) to each other by pointing out trends as
they
fly. Instead of the right seat saying something like, "Uh, aren't you too
far right of the localizer?" they'd say "I show we're right of the
localizer...trend continuing...no change." Seems like taking a more
business-like approach with the right seat aknowledging the left seat as
PIC
but supporting the left seat with simple information has made a world of
difference for them.

This was also revisited in the September 2006 issue of AOPA Pilot.
