Officially, no children were present or killed at WTC or Pentagon.I think you may be mistaken on this. I saw a story on one of the networks of a young African-American boy killed in the Pentagon. He had been at work with his father, the father left his office for another area of the pentagon (for a brief meeting or something)...the plane hit during the father's absence in the area of his office...killing the son, but the father survived!
I hadn't read that report. I did read in People about the African American man who worked at the Pentagon who was playing golf and so wasn't in his office at the time the plane hit. Their 11 year old son was on one of the planes that hit the WTC. He was one of the group of children on their way to educational program in Las Vegas.
