What to do?

The ongoing "discussion" of the LEX accident reminds me
of an incident I experienced many years ago of potential
pilot error. I was a passenger on commercial flight on
a smaller airplane (make and model not recalled but it
was twin-engine turboprop). As we were making the
approach to land, I could see out the windshield and
noticed that we were overshooting the field on final.
Other observations indicated that whoever was doing the
piloting wasn't very good at it in the sense of at least
being lightly experienced. A question I pondered at
the time and since is whether I should have hollered
at the flight crew to correct the descent path or go
around. One doesn't want to panic the other passengers
needlessly but one also doesn't want to quietly be one
the first to arrive at the crash scene either.
