No Jim, I actually know that report, and the statements of both the
airline and Airbus too. The surprise is in knowing that such action,
which I think is natural, isn't automatically built into in the design
of an aircraft. Why do you think that's so? Aren't such boat-turns
normal? Should be, isn't it?

Turns in aircraft are most often intended to be what is called
"coordinated." That is the ailerons and rudder are used in conjunction so
that there are *no* purely horizontal forces felt by the passengers. In
airline and corporate flying this is sometimes called "not making the ice
cubes clink." You try to maneuver the aircraft so that the passengers, and
their drinks, are not disturbed.

Making these boat turns would be like filling a station-wagon automobile
with children, accelerating to highway speeds, and then making an abrupt
turn of the steering wheel. The children wuld go sliding all over the car's
cabin.
