A security camera from a downtown energy corporation captured a bizarre sight in the eastern sky over Kansas City last week.

The video shows an object that appears to be slowly falling in the sky around 8:30 a.m. on Jan. 14.

Bob Lindsay, a security worker at Trigen Energy Plant, spotted the object on security monitors and asked a co-worker to zoom in on the mysterious image.

"It had the appearance of more of a really light yellow -- wasn't quite white, wasn't quite yellow," Lindsay said.

Lindsay believes he saw a long vessel, like a missile or rocket aircraft with flames shooting over the nose and up its sides. The staff at Trigen has come up with several theories about the nature of the strange image.

"We got UFOs, we got experimental airplanes -- a jumbo jet maybe? There's a lot of guesses going around," Lindsay said.

Kansas City TV station KMBC-TV showed the tape to astronomer Tom Armstrong, who has worked extensively with NASA.

Armstrong guessed the object could be man-made space debris, but it's more likely just a meteor skimming across the atmosphere.

"If you've watched a meteor shower and you put this at night against a star background, you'd probably think meteor," Armstrong said.

He added that meteors often give off what looks like a long tale.

The North American Aerospace Defense Command, known as NORAD, said it was not tracking any man-made space junk reentering the atmosphere on Jan. 14.
