Do modern jet airliners still have a noticeable dutch roll? I haven't
flown in anything for a couple decades, and was wondering if it's been
damped out to zero by modern control theory, or still exists.

I first noticed it trying to take solar sights with an elaborate
protractor and bubble level setup on trans-Pacific flights, in
DC-6's and later 707's (something to do). It was a few degrees
in roll magnitude, quite noticeable. You'd think today it would
be gone completely, though, but I don't know.

It came to mind because my bicycle seems to do the same thing under
heavy baggage load. No doubt from a different cause.
