Large rectangle 168th blondo Omaha neAt first sight it appeared to look like a pair of bright white headlights in the sky with a flashing red light on the back when it turned 90* to the west. It was heading from approximately 156 and blondo and we saw it coming toward 168 and blondo. Flying low - the altitude of a helicopter. When we got closer, and were practically underneath it we looked up. No noise made by the craft completely silent. Very large rectangle shape with mini white and red lights underneath. It turned sharply to the southeast and took off. The last time we could see it it looked like a string of white lights in the sky moving rapidly toward the dodge expressway.Side note: think we saw the same crafts about 45 mins earlier at 156 and dodge area.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
