Large low-flying craft with orb like lights in a cross shape.My 16 year old neice and 3 year old son were in the car. He was sleeping in his carseat. I exited I-235 westbound exit 5 -56th street and turned northbound on 56th street. Immediately my niece and I simultaneously saw a large triangular ufo with many orb/sphere like lights on the bottom. There was a light at the point of each of the three angles in the triangle. And a cross of lights from the top tip down. It did have a sound it was very low to the tree line right over the hospice house there I shut the radio off and we were the only car right there. The craft was large and was flying quickly in a nw motion swopped behind the trees and we turned to follow it and it literally disappeared behind the trees. We didn't "see" it take off and we looked for it but couldn't find it.
