9/11 was a very sad day. So many people died that day.Even first responders died that day trying to save people. 2 hijacked planes hit the World Trade Centers another hijacked plane hit the Pentagon. another plane was in the air it was hijacked and was heading for something else but then the people on flight 97 made a plan they has boiling hot water hot coffee and then they charged to the cockpit the hijackers started moving to planed up and down side to side to knock them to their knees. but then they said bring the plane down and then it crashed in a pennsylvania field. if it wasn’t for those heros the plane would have hit something else.
