GB I had a passenger sleeping while I was following one of those
GB large tow trucks that was towing a semi-tractor by its
GB tail. She woke up and screamed at first until she realized we
GB weren't on a collision course with the semi. Sure startled
GB me...

I had a kid scream a few seconds before landing in a C182 "we're going
to crash!!!" I remember thinking, humm, I don't think my landings are
that bad, does he see another plane??...then I realized he wasn't used
to the sight angle out the front of a Cessna in a steep descent with
40 degrees flaps.

I've had other pax ask if something is wrong when the throttle is
pulled back on downwind.

An instructor told me that one time slipping a plane to landing, his
wife thought they were going to crash.

Makes you realize that what to pilots are perfectly normal things, to
pax may be their last moments.
