"Untersuche" is "Investigate" in GermanWibren Visser is a key member of the Architects and Engineers for 9/11 Truth Translation Team. Born in Holland, and now living in Linz, Austria, he studied philosophy for two years, graduated from a hotel management school, and has a degree for Dutch translators from the University of Vienna. He currently works as a sales controller specializing in reporting and data mining, but has been doing translations – German to Dutch and vice versa – as a sideline for over 25 years.

In 2008, Wibren was searching the internet on the subject of weapons inspections in Iraq and stumbled onto some information related to 9/11. He says it was "a total surprise to me, as I was not aware of any doubts about the official theory. That intrigued me and I started looking for more information." Coincidentally, Richard Gage, AIA, was touring Europe at that time and likely passed close by Wibren's hometown.

Soon after, Wibren noticed materials from AE911Truth. He felt that our group was the most credible organization within the 9/11 truth movement and signed our petition.

WTC Tower construction showing core columnIntroduction

To believe the official conspiracy theory regarding the destruction of the three World Trade Center high-rise buildings requires an Olympian leap of faith. It asks us to accept impossible coincidences, to assume the laws of physics don't always apply, and to ignore common sense. Being one of 9/11's least likely hypotheses, it requires that we emotionally moor ourselves to its tenets, because an intellectual examination or inquiry would quickly reveal dots that don't connect. Fortunately, a much more cogent theory exists. It suggests that controlled demolition, not fire, was the cause of the collapse of WTC Buildings 1,2, and 7.

But this theory, although supported by overwhelming scientific forensic evidence, eyewitness testimony, and visual documentation, is nevertheless rejected by official conspiracy theorists. On the grounds that it presumes impossibly high logistical hurdles for the perpetrators, the official conspiracy theorists argue that a plan of such magnitude would have been impossible to carry out. How was security breached? How were necessary cables and other equipment moved into the buildings unseen, and how did a demolition team gain access to structural members? To investigators and degreed professionals who have studied the evidence, these questions are elementary. What follows is a simple, yet compelling, visual and scientific narrative, which explains how the controlled destruction of World Trade Center Towers 1,2, and 7 was accomplished.
