The death toll from the September 11 attacks is 2,977. I have a few more facts about the attacks that I could share with you. For example, the two hijacked planes crashed into the Twin Towers of the World Trade Center in New York City. The first plane crashed into the north tower, which collapsed, killing everyone on board. The second plane crashed into the south tower, which also collapsed, killing everyone on board.
