Saw craft overhead red lights changing from 2 to 3 triangles together

I was on my backyard deck with my dog just as a clear night settled in. I noticed a triangled red light set just above the horizon from the east...as I watched it, it began to rise in the sky (or had been moving straight at me) and began flying at me at a quick speed. As it started to fly directly over there were at first 2 triangles, red in color, then it looked like there were 3 red triangles flying side by side overhead. As I was watching there were 2 triangles flying directly back east a bit more to the north. I was a bit shaken because I had never seen anything like these things before. I ran in to get my phone to get pics if it came back and accidentally (or my phone had)woke my husband. He eventually came out as another set of red-lighted triangles (2) flew overhead from the east but he said it was a plane. It didn't look like any plane I have ever seen or ever flew that low east to west over our home. They were huge. And we live northwest of a small airport and Interstate 88. As that one disappeared, I saw one more set maybe a mile south of us fly west. Was there noise? I couldn't say for sure because of the noisy interstate but there was no normal hum of an engine had any other plane flew over to the airport nor was there a jet engine sound as I would suspect of a plane that large (if it was one). Very strange, and may have not been anything BUT it was unlike anything I have ever seen in 66 years on earth. Lasted about 5-8 min maybe and to be honest it could have been closer to 9 PM.
