3 triangle craft, 2 red and one yellow/amberStrange orange light appeared against the stars in the north east. Seeing that this was a bit strange, I went to get my binoculars after a few minutes of observing this strange light. After retrieving my binoculars, it came closer at a high rate of speed. As it turned to go west I observed what was orange, now become 2 red objects and one yellow/amber object. The light from all 3 objects did not strobe and the lights appeared as orb/arrowhead shapes in single file one behind the other with two red and one the amber object trailing. As the craft came closer these craft were of triangle shape and all were of equal distance, but then converged into a triangular formation. The amber was at it's highest point in the triangle formation, and as the objects traveled through the sky, the formation changed to a single file formation and then back to a triangle formation with the amber object now at the bottom of the formation. There was no sound from these craft and there were no aircraft in the area at the time of the sighting. The speed was enormous for the distance I observed. The objects were about 32-36 thousand feet (perhaps less), descending quickly and were about 3 to 4 miles away. I was able to observe the object for about 6-7 seconds going west. I have a nearly unobstructed 180 degree panoramic view from the back of my house which points almost directly north. I live in an area that has a lot of airplane traffic, so I know these were not planes. However, soon after, there was a plane that flew over my house and then abruptly changed direction, the same direction that these craft were headed. My background- I have served in the Air Force for 12 years, and held a Top Secret/SCI clearance and have worked around aircraft during my time in and I was also stationed At Cheyenne Mountain/NORAD for 8 years.I would have sent this in sooner, but I wanted to make a better drawing to send in so I could show the time line and events
