My take on what he said about this is he recognized two of the terrorists from the pictures of the 9/11 terrorists. One was especially easy to recognize, the one that had a v-shape hairline, because he looked to Woods exactly like an actor. Woods became a little fuzzy here because not only was O'Reilly interrupting him but Woods said he couldn't speak too much about this because of legalities and the fact he may be called as a witness. From my understanding of what Woods said, there are two men who were on his flight who are still out there, who did not die on 9/11. [I'm impressed you noticed this and apologize for being more clear on this important fact.]
