Caribbean Sea, revolving boomerang shape with lightsDuring a cruise in the Caribbean (somewhere north of Cuba) my wife and I were looking out to sea from our balcony and noticed a light (star sized moving in a north easterly direction). At first I thought it must be a satellite but it then changed direction very rapidly (90 degrees) as it approached our ship at an unknown height. We could clearly see it had a boomerang shape and was revolving (with multicoloured lights). It then passed over the top of the ship so we lost sight. I looked at my wife and said "did you see that?" and she confirmed. Any idea what it could have been? Anyone else se it?
