Hudson Valley area. Large, silent, triangle shaped vehicle hovered about 100-200 ft over the house for about 3-4 minutes.

My neighbor's three children came running and pointing to the sky.  I looked up and saw lights in a a triangle shape not more than 200 feet overhead.  It moved VERY slowly and made NO noise.  My boyfriend was also with me at the time.  He is an amateur pilot but could not explain what the object was.  My first thought was that it was small planes flying in formation, but there was no deviation between lights and no movement...it seemed to be one huge object...about the size of 3 football fields.  Later, they said it was ultra-lights, (from Stormville) but nobody who saw this and other similar sightings agreed.  There were several sightings over the course of the year in  the Hudson River Valley.
