The most notable US Navy losses, which have occurred in the Bermuda Triangle, are USS Cyclops in March 1918 and the aircraft of Flight 19 in December 1945. The Navy believes that the Cyclops probably sank in an unexpected storm and that Flight 19 probably ran out of fuel and crashed into the ocean. No physical trace of either vessel has ever been found. Did they travel in time? Or were they taken from an unknown force?
