The Twin Towers was the name most people referred to 1 World Trade Center (the North Tower) and 2 World Trade Center (the South Tower). These two buildings, along with 3, 4, 5, 6 and 7 World Trade Center, comprised the World Trade Center complex, which stood in lower Manhattan, in New York City until September 11, 2001. The total cost of the complex was $400 million. When the Twin Towers, designed by Minoru Yamasaki and Emery Roth, were opened on April 4, 1973, they were the tallest buildings in the world, standing 110 stories.
On September 11, 2001, in arguably the most horrific act of terrorism ever committed in a single day, members of al-Qaeda, an Islamist militant group that was founded by Osama bin Laden, flew a Boeing 767 jetliner into each tower. One hour later, the South Tower had collapsed followed a half hour later by the North Tower. By the end of this ghastly day, 7 World Trade Center had also collapsed, leaving 2,753 people dead and many more injured. All other World Trade Center buildings were later demolished due to being damaged beyond repair.
In the coordinated terrorist attack on that fateful Tuesday morning fourteen years ago, nineteen members al-Qaeda hijacked a total of four planes. One of the four crashed into the Pentagon, located in Washington, D.C., the fourth plane crashed in a field outside Shanksville, Pennsylvania after passengers, who learned of the other hijackings via cellphones, attempted to retake control of the plane. All told, nearly three thousand innocent people lost their lives that horrendous day.
