Large group of white objects with four red objects flying away from itAt 7:45 AM on September 14 I was playing doubles tennis in Henderson, NV. The players on the other side kept looking up in the sky and pointing so my partner and I went to see what they were looking at. They thought it was a flock of white birds way off in the distance. We all watched the irregular formation of about thirty white objects and noticed that it was completely still and not moving like birds would do. We watched it for about a minute and said if it was balloons they’d probably be moving around in the wind. The formation remained still but then we noticed 3 red objects come from within and they were definitely moving in formation away from the white objects. The three red objects were joined by a fourth and they were moving to the south. The red objects were so high you could barely see them but the four of us did see them and watched until they were so high they were no longer visible.
