White orb seen trailing airplane at same speed.One white circular aerial object was witnessed trailing an airplane. The sky was blue and the white object was easy to see against the background of the blue sky. The white object was traveling behind the airplane, seemingly at the same speed.((NUFORC Note: The witness provides high-quality video and stills of the object, but it is barely visible. It is little more than a tiny, light-colored speck. We do not know what it was. PD))
