The day of 9-11 was a very sad day for families who lost important people in their lives.Four planes crashed that day.Two of them crashed into the World Trade Center.Hijackers killed the pilots and took over the planes crashing them into the Twin Towers.One plane had kids on it that were going on a field trip to Washington D.C.The plane also had hijackers on it. The plane crashed into the Pentagon.All of the kids including other people on the plane lost their lives.The last plane had people who cared about not hitting the White House.So the people took over the plane and they crashed it into an open field.They also lost their lives.Never forget the day of 9-11!!!!
