Strange UFO seen in Colorado

There's a new kind of UFO being seen in Colorado.

It's not an egg. It's not a football shape. It's not a cigar. And it's certainly not a flying saucer.

Tim Butler, a sound engineer from Durango, says he saw a silent, silver, flying boomerang – about 40 to 60 feet long – sweep over Fort Lewis College while flying a little higher than 1,000 feet, according to a report in the Durango Herald.

Butler witnessed the craft in the sky Sept. 28 and has since found out others in Colorado saw something similar about that time.

Other similar reports of a boomerang-shaped craft were recorded in the Silverton Standard more than a week earlier.

Butler told the Herald he is a scientist at heart and believes what he saw was evidence of unknown technology – possibly military.

"It wasn't thermalling and didn't make a sound," he said. "There was no heat distortion behind the end. I thought it had to be a military drone at one point but there was no contrail, no propulsion."
