I am wondering what is involved with trailering and setting up an average
(popular model) glider.

As we lawyers reply to most questions... "It depends".
It depends on the trailer fixtures and how easy, or difficult, they make it
to move your glider parts around.
It depends on whether your glider has automatic control connections. If
not, it further depends on what type of connections the glider has.

Can one reasonable expect to park the car, unload the trailer, and have
glider ready to fly in under 90minutes?

Again, it depends on the glider. I used to own a 2002 Glasflugel that I
could assemble, tape, preflight and be ready to stage in 45 minutes. It
took an hour if I didn't have a helper.

Does it usually take two people?

Yes. unless you have some type of one-man rigging aid. Some gliders,
particualrly those with heavy wing panels or difficult control connections
will require a third person to assemble.

Do gliders ever have wings separate in flight due to weak attachment
points?

I don't know of any instances of gliders breaking at the assembly point.
Maybe someone who's been in this a lot longer than I have can answer that.
