29 November

A stretch of the western Atlantic between Florida, Bermuda and Puerto Rico, described in a 1964 magazine article as a zone where ships and planes vanish. Losses linked to it include the five bombers of Flight 19 in 1945; the U.S. Coast Guard and NOAA say the losses there have ordinary physical causes.

From November 1989, starting near Eupen, people in Belgium reported large triangular objects flying low and silent, in a wave of sightings that ran until 1991.
