Triangle shaped craft that moved like nothing I’ve ever seen.

While driving with my wife we both saw what at first appeared to be a large helicopter moving horizontally across the sky , it quickly turned and came straight at us and went right over head and we saw it plainly. It was moving like something out of a sci fi movie and was triangular in shape with what looked like a green and red arrow lights underneath. Definitely not a drone, helicopter or airplane. Just after we saw it my wife said , watch out for that deer crossing the road. It wasn’t a deer and we can both only describe it as a mix between a llama and a hyena. Don’t know if the two are connected but that’s what we saw. Was looking for a place to pull over to try to get a pic or video of the craft when we saw the animal then decided to just get the hell out of there. Rural road and we weren’t taking any chances.
