I was one of the people who saw the UFO in 1989, there was nothing special
about it, we noticed it (my family and I) because of the travelling speed

Does anybody know of what it was exactly ? Unable to find any valuable
information on this...

The belgian research group 'SOBEPS' published something
on the flap (at least in french (in german at 'Zweitausendeins'),
and excerpts should be found on the net.

Translations in english as well, AFAIK, for example the reports
from the intercept trials made by the belgian F-16s.


German excerpts on Belgium
(and some reports from elsewhere/elsewhen)
can be found at

The radar analysis' where made by Prof. August Meesen,
a physicist from Leuwen/Louvain.

Maybe this is useful
