I know that the terrorist that planed the plane crash was, Osama Bin Ladin. Three planes were taking over and two went to the twin towers. One went to the pentagon put it crashed in an empty field in Pennsylvania. The men that did this act were part of a religion that told them that if they went out in suicide they would go to heaven and have a bunch of women. They died to kill american citizens just to have a lot of women and because they thought it was right.
