Mass of Black DOTS MORPHS into distinct V-shaped cloud

At Appox 10:15 am on the 1 of May, I was travelling near RTE 1, Green St Intersection when my attention was drawn to the south-west, where  a black/charcoal grey  mass of semi transparent  "DOTS" that was "floating" North  was viewed by me  as it traveled   at a constant speed and direction,  changing shape at approx 1000ft altitude. A state trooper was also  stationed at traffic duty, he observed it too, and joked as long as it don't suck his brains out, it's OK! I continued  west on Green St for 1/4 mile, keeping morphing cloud in sight, it also had Tendrils with smaller spheres hanging off of it,  then the "cloud" with and ill defined rear, changed shape into a sharp "V" formation and contined over the tree-tops out of my line of sight. No sound was heard and no birds or insects could produce this straight line, constant ballastic type of flight. Weather cover  was ashen grey sky  with the clouds above this "thing", which I feel was a controlled object of mechanical or biological in nature. See also NY report for morphing cloud for similar description of type of  "object"
