I saw a white ball moving slowly across the horizon. it was moving in a straight line. i could hear no noise. it moved past a hotel, over a small island, and i believe eventually out over the water past the island. it moved in a straight line. we see many helicopters out there and this was nothing like a helicopter. it eventually disappeared from sight. i am guessing it turned to moved across the island, out towards the water where we could no longer see it.
