A diamond-shaped UFO appeared over Lincoln, Nebraska, on September 4 ABC's KLKN Television

A diamond-shaped UFO appeared over Lincoln, Nebraska, on September 4. The sighting was videotaped and broadcasted by ABC's KLKN television affiliate. The twinkling, color-changing object remained in the sky for 45 minutes until it finally disappeared at sunrise.

"I have never seen anything like this before. Even I don't know what this is," KLKN's morning meteorologist Sean McMullen said. "At times, it seemed to have tethers hanging from it, but I really think that's just an artifact."

Open Minds.tv reported that the sighting was not the first one to occur. Rich Webb, a local member of the Mutual UFO Network, told KLKN that a triangular-shaped UFO was reported 200 miles away from Nebraska.

A source in Federal Aviation Administration (FAA) said to have no accounts of unusual activity in the air on that day. Professor Timothy Gay of the University of Nebraska-Lincoln physics department said that he could not guarantee that extraterrestrials do not exist. However, he suspected that the footage was a government aircraft of some sort or a human lens reflection phenomenon.
