The University of Alaska Fairbanks will host a public presentation on an ongoing study into the collapse of World Trade Center Building 7 at 4 p.m. Wednesday, Sept. 6, in Schaible Auditorium.

UAF researcher Leroy Hulsey is leading the study. He will present the findings outlined in his team’s September 2017 progress report, which will be released the same day. A draft report of the two-year study will be issued later this fall, followed by a six-week public comment period, with a final report scheduled for release in early 2018. Hulsey’s study is being funded by the nonprofit organization Architects & Engineers for 9/11 Truth.

WTC 7 was a 47-story office building that fell nearly seven hours after the collapse of the World Trade Center’s Twin Towers on Sept 11, 2001. In a 2008 report, the U.S. Department of Commerce’s National Institute of Standards and Technology attributed the collapse to office fires in the lower stories of the building.

The presentation is open to the public and will be streamed live at 4 p.m. Alaska time at https://media.uaf.edu.
