Large metallic cylinder seen floating in New Hampshire sky before disappearing.

At about noon time Monday afternoon my father and I spotted a long, narrow, cylindrical object floating away from us in the sky. It was very breezy outside but the object seemed to be moving at its own pace.  The object had a slight arc in its shape but beyond that looked like a large metallic pool noodle and at one point seemed to reflect the sun back at us. It was far enough away that it was hard to tell just how big it was.
The object was floating away from us over a lake, we were watching from just  behind a group of trees on the shoreline. Once the object passed from our view ( beyond the trees) I ran to the water line and looked up for it, it was gone.
There was no noise from the object.  My father and I have no explanation it.
