I was on a yacht headed south off the coast about 5 miles. There was hard to above me so I saw the bnb object when it dropped below the obstruction of my view. It was very bright and the light cloud cover was lit up by the objects. It was moving very fast and seemed to have a flash right before it disappeared. I listened for a boom but didn't hear anything. One of the coolest and most startling things I have ever seen. My view only lasted a couple second. It seemed to come from the west moving east.
