Dr. Wood says this is the only comprehensive-forensic investigation to date in the public domain.

Dr. Judy D. Wood is a former professor of mechanical engineering with research interests in experimental stress analysis, structural mechanics, optical methods, deformation analysis, and the materials characterization of biomaterials and composite materials. She is a member of the Society for Experimental Mechanics (SEM), co-founded SEM’s Biological Systems and Materials Division, and has served on the SEM Composite Materials Technical Division. Dr. Wood received her B.S. (Civil Engineering, 1981) (Structural Engineering), M.S. Engineering Mechanics (Applied Physics), 1983), and Ph.D. (Materials Engineering Science, 1992).

She started to question the events of 9/11 on that same day when what she saw and heard on television was contradictory and appeared to violate the laws of physics. Since that day she has used her knowledge of engineering mechanics to prove that the collapse of the World Trade Center twin towers could not have happened as the American public was told.

In her book she describes how the towers were disintegrated with a process described as “dustification” which turned the debris into dust before hitting the ground.
