Three people see orange lights in the western sky at night. One dims and re-lights in a horizontal row. 50 second video taken.On January 14, 2014, at 1845 hours, I got a call on my cell phone from my sister to come look at some strange lights in the sky. I drove to her location and arrived about 1 minute later. We observed two yellowish-orange lights in the western sky. The lights moved up and down and dimmed out, and then lit up. At one point, a series of three lights lit and dimmed in a straight horizontal row. The night was clear and calm.I pulled out my cell phone and was able to video the lights for 50 seconds until they disappeared.After the lights dimmed out, we heard a distant rumble like a jet engine. We could not see the cause of the sound, but assumed it had a connection with the lights.
