3 spheres above the Los Angeles HarborMy daughter saw what she thought was a mylar balloon just hovering high above the sky. When I looked up, I saw 3 spheres just hovering in the sky. I am going to guess at least 20K feet above the ground. The spheres where in a triangle form. After about 10 minutes the all moved to the north. A few minutes later, one shot to the south at supersonic speeds.
