A formation of approx. 16 round fire orange guided craft entered the western sky at "10 o'clock" attitude. As I was watching the clear sky the objects appeared to blink on as if entering the atmosphere and heated up. There was a larger craft leading 5 or 6 wings of 3 of about one third the size. First they were viewed from above then made a turn upward and toward the north at which the bottom of the formation could be seen. As they continued they took a sharp angle upward and the top of the formation was again observed. The exit angle was at about "11 o-clock in the northwestern sky. The formation was approx. 6 times longer than it was wide.
