On June 10, 2010, Dr. Fahim Sadek of NIST (fahim.sadek@nist.gov), an investigator who produced the Bush Administration's report on the WTC, gave a lecture at the Engineering College of Aarhus on the entire WTC Investigation. This is apparently the only time that NIST has given a detailed talk on their entire investigation.

It was expected that Sadek would take questions at the end of the lecture. However, nobody was allowed to ask any. Nevertheless, before Sadek left, Dr. Niels Harrit managed to catch him for a brief talk.

Three months before on February 28th, 2010, Dr. Niels Harrit gave a presentation on the collapse of World Trade Center 7 in Aarhus, Denmark, as well. Hundreds of invitations were sent to both journalists, city council members and various members of the scientific community. More than 300 people attended, among them several professors from the Engineering College of Aarhus.

Despite prohibiting filming or any other documentation of Sadek's presentation, over an hour of video the presentation was pieced together from several hidden video- and sound recorders. This is that presentation and the Sadek-Harrit exchange.
