De Brouwer wrote the preface for the book "UFOs above Belgium', writtem by John van Waterschoot, reknowned mathematician and economist, professor at the University of Leuven. Here are some excerpts:
"Personally I was very sceptical about the sensational press reports of triangular UFOs being sighted above Belgium on November 29th 1989, which was the start of the UFO-flap - I thought the cause of the phenomena were either laser beams or holograms."

"The witness accounts were coherent and convincing. The witnesses themselves were credible, even if their stories seemed like something out of science fiction."
>>>
"...newspapers suggested that F-117 Stealth planes were responsible, planes invisible to radar. This is easily determined as wrong: no permission was granted for such activities in the Belgian air space, on top of which these Stealth planes were incapable of flying at around 60 kilometres per hour, then shoot off at incredible speeds, without any loud noise."
"The reaction goes from indifference to rejection to disbelief, and to the intense conviction that UFOs are from extra terrestrial origin. The fear of being ridiculed is real and is inspired by the fact that many find it difficult to accept we are visited on a regular basis by extra terrestrial craft, be it manned or unmanned."
