I agree, Jay. I usually fly with a pilot/friend, and we don't split
preflight duties for that very reason also -- too easy for both to think
the *other* checked/did it. We do overlap each other though (both do the
checks) on the verification of fuel, oil and cowl latches.

With the kids now nearly grown, I find that (if I'm not fetching a
quart of oil, or a rag, or something from the hangar) I will usually
follow Mary around during the walk-around, viewing things at a
discreet distance.

I've never caught her forgetting anything yet, but IMHO two sets of
eyes are better than one.
