Watch: Series of Missouri UFO Sightings Continue to Baffle

Missouri resident Justin Johnson captured something extraordinary on his phone-- a silver cube spinning like a disco ball. But what was it? Johnson is still waiting for an answer. He reached out to weather balloon enthusiasts and air traffic controllers, but no one could identify the hovering object. He tried to follow it in his pickup truck but lost sight of it. Three years later, the memory still baffles him. At the time, it was hard to find someone to objectively assess the video.

Just a few weeks ago, Johnson recorded a new video that shows enigmatic white light objects moving in the sky at sunrise. But today, he has a new option for analysis-- an app called Enigma that allows users to upload videos and information about unexplained objects in the sky. The goal is to create a comprehensive database of these sightings for researchers to analyze.

Alejandro Rojas, a consultant to Enigma Labs, says most cases are simply explained-- airplanes, drones, military flares, or satellites. But sometimes, Enigma's experts encounter something more puzzling, like footage an airline passenger recorded of a thin, white object zooming across the sky over north central Missouri.
