What are these helicopters up to?

I was out snowshoeing off of the Foxfarm Road on Friday (March 15), and two helicopters and a fixed-wing aircraft passed overhead, flying in sort of a formation.  The lead helicopter was a huge twin-rotor thing, with some sort of device hanging from it which almost seemed to be emitting some sort of vapor trail. Strange. Did anyone else see this, or better yet, does anyone know what they were up to?
