Heavily populated area with incoming and outbound aircraft from the airport, UFO objects overhead, and visible to witnesses.A friend and I were traveling 60 mph, going west on SR-500 in Vancouver. 1/4th of a mile before the I-5 on ramp going North. We spotted objects that had several bright lights. They were in the sky directly in front of us. In the distance at a glance they looked like aircraft, but not airplanes. They were lined up too close and moving too slow to be incoming airplanes, they almost seemed to be hovering very low above downtown Vancouver, WA. As we approached our freeway on ramp,the biggest craft went over the top of us and was literally less than 100 yards directly south of the Driver side window, we were able to watch as it passed over the front/ top of us and lowered almost to ground level. It was very big triangle shaped, as it lowered it seemed to be slowly rotating, so we saw the underside of it. It was grey, metallic looking almost liquid. The light configuration was strange, there were several very bright lights that seemed to run along the bottom with brighter bigger lights on the corners of the bottom of the craft. There were several other similar objects in the sky immediately in front of us, we were on the freeway and had to turn and head north and the sky is not visible from where we are in Vancouver.
