This week on 9/11 Free Fall, architectural engineer Jef Bishop joins host Andy Steele to give a recap of his recent, well-received presentation on Building 7 to the Biloxi, Mississippi, branch of the American Society of Civil Engineers.

They also talk about the larger battle to get the 9/11 evidence out to engineers and the general public in the face of a growing clampdown on the free exchange of ideas by professional institutions and internet platforms alike.
