The Story

From 1989 to 1991, over 13,000 people reported large black triangular craft with bright lights over Belgium. On March 30–31, 1990, F-16 fighters scrambled twice and obtained brief radar lock-ons on objects performing extreme accelerations. SOBEPS documented over 600 reports with photographs.
