After investigating 800 sightings, NASA has been able to confirm that none looks like they come from another planet. Of the 800 phenomena investigated, the hired experts were able to explain almost everything.

The panel represents the first investigation of its kind ever conducted under the auspices of the U.S. space agency on a subject once entrusted to the exclusive and secretive purview of military and national security officials.
