According to videos posted on the internet, strange aircraft have been circling US naval vessels in apparently safe seas in recent years. No one knows exactly what they are. Unidentified Aerial Phenomena, or UAPs, is how the military refers to them. Whatever they might be, the government is taking serious steps about them. Congress ordered the intelligence community to send a complete analysis on the instances in December. The Pentagon’s inspector general declared a probe earlier this month to “determine the degree to which the Department of Defense has taken measures on Unidentified Aerial Phenomena.” Several members of Congress have also pledged to investigate the situation.
