I got a copy of this letter from the LDS-YW Yahoo Group:

Dear Brethren:

Wearing of White. Non-ceremonial Clothing Outside the Temple

The Temple Department continues to hear reports of events where
the white, nonceremonial clothing is being worn outside the temple and
where the sacred symbolism of temple ordinances is being spoken of
publicly. Such events have included a stake presidency dressed in white for a session of stake conference, appearances on handcart treks and at firesides, and participation in an activity depicting an airplane crash
where the passengers end up in a room full of people dressed in white.

The white, non-ceremonial clothing worn in the temple is a
reminder not only of the purity required of those who participate in the
sacred work of the temple, but also of the special and sacred place in which that work takes place. Such clothing should always be treated with great respect and never allowed to become commonplace.

Inasmuch as there is significant symbolism attached to changing
from everyday street clothing to white clothing in order to participate
in sacred temple ordinances, it is felt that this clothing should not be worn outside the temple.

We request that you discuss.this matter with priesthood leaders as
you meet and counsel with them. It would be particularly helpful if
this matter could be on the agenda of a Coordinating Council at which you
or one of your counselors were invited to attend.

It would also be helpful to remind priesthood leaders and members
who have been endowed of the sacred nature of the temple covenants and
of their obligation to avoid speaking outside the temple of ordinances or instruction that should only be spoken of in the temple.

Sincerely,
Ronald A. Rasband
Executive Director

I used to have the airplane crash activity on this website, but because of various doctrinal concerns, I removed it. Now it appears there are several temple-related flaws including the wearing of all white (among others).

So, my advice is -- avoid the airplane crash skit:

1) it's insensitive to those who have actually had a friend die in a plane crash -- this did happen in our branch
2) the skit called flight 409 is actually based on a real event! How offensive to the families of those deceased!!!
3) even with my own limited knowledge, I've spotted serious doctrinal errors in every airplane crash skit I've seen.
4) we've been asked not to try to recreate the reverence found in the temple by wearing all white
5) in those skits where people are separated -- some don't "make it" to the Celestial Kingdom -- this can be taken as judgemental by those struggling members, and spiritually crippling to youth and adults trying to be better.
6) the skits come dangerously close to mimicing temple patterns
7) motivating people by fear isn't an effective long-term teaching strategy
