Numerous reddish orange spheres moving at high speed from north to south.Neighbor rang our door bell around 8:30 PM on Saturday, September 13, 2014. Upon going outside, my wife and I saw several groupings of round, reddish orange objects, in a very loose formation, traveling north to south at a high rate of speed. What appeared to be sparks were falling from the sides and trailing edge of several of them. I was looking at them through 16 power binoculars. The bottom of each round object appeared to be composed of multiple circles of light such as an LED flashlight. We heard no sound from them. The height was above the cloud layers. The clouds appeared to be at or above 15,000 feet. The cloud layer they overflew was approximately 10 miles due south of our location. They appeared to be well above that cloud level. There were 3-4 loose formations of 8-10 objects. Several minutes after the last formation there were two “Tail End Charlies.” I am an ATP/CFII/MEI with over 4000 hours.
