Two complementary videos are combined here in the order that they were presented at the 9/11 Truth Film Festival in Oakland, CA, on Sept 10, 2015.
The first video is a preview of the witness section of a forthcoming film by Ken Jenkins titled The Pentagon Plane Puzzle.
That is followed by a PowerPoint presentation by David Chandler titled Going Beyond Speculation – A Scientific Look at the Pentagon Evidence. In post-production, Ken Jenkins of 9/11 TV added many additional graphics to the live video footage of Chandler’s presentation.
David Chandler’s presentation starts at 26:40.
