There won't be an alien unmasking. Two officials briefed on the report say it found no extraterrestrial link to the sightings reported and captured on video. The report won't rule out a link to another country, according to the officials, who spoke on condition of anonymity because they weren't authorized to discuss it. While the broad conclusions have now been reported, the full report may still present a broader picture of what the government knows. The anticipation surrounding the report shows how a topic normally confined to science fiction and a small, often dismissed group of researchers has hit the mainstream.
