2 triangular shaped objects moving quickly, smoothly and quietly together

My boyfriend and I saw two triangular shaped objects traveling south above us. They had three lights in the shape of a triangle and there were two. They were moving so fast and got so close to each other in complete silence. I’ve seriously never seen anything move the way they were moving in my life. They were probably as high up as an airplane when you can still see it all the way and they were at least the size of a plane. I don’t even know how to explain it they were moving so weird, quick and hovering kind of. It was like the 3 lights weren’t in a perfect triangle they were moving separately together in the shape of a triangle. The way the objects moved is nothing like I’ve ever seen before. No plane could move this fast, has this shape and is able to move the way these objects were moving. It was like something out of a movie and one of those things you have to see to believe. The lights were brighter at first but faded as they moved. The lights were a dim white. They just looked like little metal saucers and they weren’t blinking. They flew south over us for a second or two and then disappeared. I am the last person to believe in UFOs, I’ve never believed the stories I read but there is nothing else this could have been. It was mind blowing and it happened so fast. It was something I really wish I could have caught on camera because it sounds unbelievable when I say it out loud. I’ve never seen anything like it in my life.
