The Belgian wave, fighter response and Petit-Rechain photograph
Eupen and other locations across Belgium
Witness account
Reports of unusual lights, often described as triangular craft, accumulated after the night of 29 November 1989. On 30–31 March 1990, two Belgian F-16s were scrambled following further reports and radar indications. The pilots did not visually identify an anomalous craft. The frequently reproduced Petit-Rechain triangle photograph belongs to a separate alleged episode in April 1990.
Public record
Belgian military reporting is discussed in released British Ministry of Defence files, confirming a real response and contemporary uncertainty. Radar contacts, ground observations and later civilian testimony are not automatically observations of the same object. In July 2011 the Petit-Rechain photographer acknowledged constructing a model, fundamentally changing the status of that image.
