I was on my deck grilling dinner near dusk and I could hear an airplane so I turned and looked up and the sky was a beautiful blue color with pink clouds and pink after trails from multiple planeswhen I noticed that there was something following a plane and closing in it I took out my iPhone and started to video it for about 1 minute till I lost sight of it.. It was chrome in color saturn looking about the size of one wing. I'd say it was within 1000 below of the plane aproximenttly on the same path going faster then the plane. It traveled under the plane and past it with no path change from either one I video'ed this object till the house next door blocked my view.. It was awesome
