A Lee's Summit, MO, witness walking in John Knox Village reports watching a "large, dull, black craft" that was triangular in shape, silent, less than 300 feet away, and under about 210 feet off of the ground that appeared to be "surrounded by a vacuum of some sort," according to December 8, 2011, testimony from the Mutual UFO Network (MUFON) witness reporting database.

"I was walking north parallel to Pryor Road, and as I ascended a small hill, I happened to look up," the witness stated. "There was an object descending and coming towards me which at first I took to be a small plane on a very dangerous downward trajectory."

The witness did not recognize the object as any known aircraft, but noticed something even more unusual.
