Yeah it was nuts. At least four helicopters hovering for quite some time in
the pattern, just south of the field. I'm surprised ATC let them get so close
since the pattern is usually so busy, especially around sunset it can be hard
to get in the D, let alone stand still in the pattern. As soon as they
finally got their shot they left quickly. Not sure if the newly arrived
spent any time visiting the Customs double-wide before getting nine squad
cars for the escort to hopkinton.
