"There is no airport in the area," the eyewitness said. "...Flickered in and out, then one disappeared as another flicked into view."

The driver believed the lights may have been flares before seeing the last light move "rapidly to the east at a 90-degree angle until it was out of sight beyond the treeline."

The Mutual UFO Network said it received the video as part of a reported UFO sighting in Katy.

The sighting is under investigation, MUFON said. You can report your own UFO sightings on MUFON's website.
