.3 X Cream/white solid circle shape objects moving in different ways very fast in the sky, no noise came from themAt approx 3am I was awake looking out on our cruise ship balcony going from Bari in Italy to Katakalon in Greece on the MSC Orchestra cruise ship. I saw what I thought was a shooting star so went onto balcony and saw a circle shape object fly towards the right of the ship, it then did a circle round and shot across and went over the left side of ship, over the top. I nudged my husband and he said go back to sleep. I could not sleep and around 10 mins later I saw 2 side by side objects coming up again. This time, I shook my husband awake and we both ran out on the balcony and watched them as they quickly side by side shot up into the sky before, turning around and shot down out of sight. It was a clear night and we could see stars, but these were fast moving white circles moving at all angles very quickly. The were solid white objects. My husband thought they were creamy yellow white colour. There was no noise at all from the objects.
