Big and triangle. Super fast. 3 round big lights under it with the colour of orange fire

Me, my daughter and my girlfriend were laying on the gras at home at night looking at the stars on a clear and cold night. Then suddenly I saw a triangle shaped craft fly by fast, faster than anything I have ever seen. It was high up to so I couldn’t see all the details on the craft. It was big and triangle and had at least 3 big round lights under it with the color of fire orange. All I could see was that it was triangle shaped and fast and the lights under it. I was shocked and said loud, I hope I wasn’t the only one who saw that. And my 10 yo daughter said yes dad I saw that. I asked first what she saw, and she said a big plane with lights under it going fast. And before I told her that I saw the same thing, I asked what shape it was, and she said triangle. My girlfriend did not see it though, but me and my daughter did. And knowing what is north and south here. It was flying west, coming from the direction of Sweden. I haven’t told this to that many people, because I was afraid, they would laugh at me. But today me and my daughter was watching top secret UFO projects declassified on Netflix. And when they came to the part of a triangle shaped craft. Me and my daughter just looked at each other and said, oh my god that is what we saw last year. It was 100% similar to what was on the documentary. And the speed was incredible. Just wanted to share this with you. This is the first time I have ever written anything like this to someone.
