"We currently lack sufficient information in our dataset to attribute incidents to specific explanations." The report made no mention of the possibility of — or rule out — that some of the objects sighted could represent extra-terrestrial life. The military and intelligence community have conducted research on them as a potential threat. "UAP clearly pose a safety of flight issue and may pose a challenge to US national security," the report said. Some could be US rivals' intelligence collection operations or represent other technology so advanced that the United States military has nothing similar. The report was ordered after more UFO sightings by military pilots became public and pilot and radar videos leaked out showing flying objects behaving strangely with no explanation.
