UFO sightings began increasing in the early 1900s and peaked after World War 2, with over 800 reported in June and July 1947 alone. The government claims to have stopped investigating UFOs but some believe it still secretly searches for and potentially possesses information about encounters. Two retired air force commanders described interacting with UFOs near the same location in France after leaving the military. While the full truth is unclear, many think governments know more than they share about UFO activity and potential extraterrestrial life.
