very low , triangle shaped craft, with no sound

My husband ,2 daughters and I were returning from a visit with my in-laws in Savannah.The kids were sleeping,and it was a warm night,so we had the truck windows down.We were going west,and at the time of sighting,there were fields,on each side of the road.I looked out of my window,to the right,and saw a large dark object flying low ,over the field ,about to enter the road .I told my husband to look and he stoped our truck to look.The object was flying very low,and slow moving,it was triangle shaped ,I would say about 21/2 to 3 times size of our truck.The object came over our truck,so low ,that I think ,that if I was on the hood, I would have been able to touch it.I looked out of the back truck window ,checking to see if any one was coming behind us ,that might have seen it too.I saw a vehicle in the distance, and it looked like it was stoping. We could hear no sound at all from the object,I saw white lights underneath but I can't remember in what shape and pattern.It was a clear night,and the object was dark colored ,I would say black.When the object went over us, it went over the field on the left,never getting any higher up,and not changing speed. I am a christian,and I know that my church does not believe in ufo's and related things,but I know what I have seen,and I know that they are real.
