A Missouri witness reports watching a slow moving "triangle craft with two slow blinking lights in the back" moving over Independence under 1,000 feet about 9:10 p.m. on April 28, 2012, according to testimony from the Mutual UFO Network (MUFON) witness reporting database.
"It was very odd - a triangular-shaped flying object that had two blinking lights in the rear only," the witness stated. These very, very bright white lights were circular and blinked on and off every two seconds (I timed it). There were no other lights on the craft like you would see on a plane."
The witness called a co-worker outside to watch the event, which lasted about 5 minutes.
"We were both perplexed because it was moving so very slowly and we decided that it could not have been a conventional aircraft. It did not look like a helicopter either. It was triangular with one end (the front) being longer than the other two sides and the edges were quite thick. The object was moving in a Northeast to Southwest direction in a straight line and did not waver from its path."
