As part of a company-funded study, based on its earlier analysis of the 1993 World Trade Center bombing, Engineering Analysis Inc. has produced a preliminary three-dimensional graphical representation of the September 11 World Trade Center attack.  The view presented is looking from west to east with the North Tower on the left and the South Tower on the right.  Also included are World Trade Center Buildings #3, 4, 5, 6, and 7.  This representation was generated by means of the VEXDAM 5.2 software, utilizing the concept of distributed vapor cloud explosions.
