Rhode Island, Providence, Nantucket, 19th January - formation flying craft of ther skyWe were driving home from a meeting of our local sports club when 4 bright lights passed in front of us, above us, following the path of the highway. At first we thought they were aircraft but then we realised there was no noise and they seemed to be dancing around each other. Then one of them suddenly changed direction instantly and flew off behind the tree line. The others stopped, wiggled a bit in the air and then disappeared as if covered by cloud. Birds looked quite confused.
