Black triangle sighting.It was a partly cloudy, south of my destination. I was driving my truck on I-70 W. near Concordia, Missouri. During my trip at around 4:30 PM I turned and saw an object in the sky, flying west along the same route I was on. The object was flying very low and was quiet. I heard nothing related to an aircraft. The object was black and in the shape of a triangle. I saw no visible windows. It was pitch black in color. I never seen anything like it. I thought it was flat and I was assured of this when the object shifted direction and started traveling southwest. When it started turning it was flat and almost turned to its side in flight.((NUFORC Note: Witness forwarded video of the sighting, but we are unable to see the object well, given that its image is very small in the frame of the camera. PD))
