Ex-US Navy Rear Admiral Tim Gallaudet said the US government is hiding the truth about UFO sightings, including 'Go Fast' and 'Tic Tac'. Gallaudet added that the government is not revealing if such spacecrafts could be hostile or not. The 'Tic Tac' UFO was sighted in 2004, while the 'Go Fast' incident was recorded in 2015 by a Navy aircraft.
