You are using the term "survey" literally, as if this was a geodetic survey
of some sort.

I meant it as being a survey of bird distribution/density and
the risk it might pose to aircraft. I was only intrigued by the
seemingly risky birdstrike situation.

Instead the goal of these passes was apparently to closely
replicate, for the benefit of ground observation and (likely) noise level
monitoring instruments, the kind of air patterns that would be flown by USN
aircraft if one of these sites were selected for use to replace Fentress.

I really hadn't considered the noise factor for that flyby
other than how the birds might react (sudden flock getting airborne,
etc). The flightpath planning aspect is a good point, and thanks.
