February 13, 1975 fire�

On February 13, 1975, a three-alarm fire broke out on the North Tower's 11th floor. It spread to the 9th and 14th floors after igniting telephone cable insulation in a utility shaft that ran vertically between floors. Areas at the furthest extent of the fire were extinguished almost immediately; the original fire was put out in a few hours. Most of the damage was concentrated on the 11th floor, fueled by cabinets filled with paper, alcohol-based fluid for office machines, and other office equipment. Fireproofing protected the steel and there was no structural damage to the tower. In addition to fire damage on the 9th through the 14th floors, the water used to extinguish the fire damaged a few of the floors below.

February 26, 1993 bombing�

The first terrorist attack on the World Trade Center was on February 26, 1993, at 12:17 p.m. A Ryder truck filled with 1,500 pounds (680 kg) of explosives (planted by Ramzi Yousef) detonated in the North Tower’s underground garage. The blast opened a 100ft (30 m) hole through five sublevels with the greatest damage occurring on levels B1 and B2 and significant structural damage on level B3.Six people were killed and 1,042 others were injured in the attacks, some from smoke inhalation.

January 14, 1998 robbery�

In January 1998, Mafia member Ralph Guarino gained maintenance access to the World Trade Center. He arranged a three-man crew for a heist that netted over $2 million from a Brinks delivery to the North Tower’s 11th floor.

The fall of the WTC

The World Trade Center experienced several major crime and terrorist incidents, including a fire on February 13, 1975: a bombing on February 26, 1993: a bank robbery on January 14, 1998, and finally a terrorist attack on September 11, 2001. The latter began after Al-Qaeda-affiliated hijackers flew two Boeing 767 jets into the Twin Towers within minutes of each other. Between 16,400 and 18,000 people were in the Twin Towers when they were struck. The fires from the impacts were intensified by the planes’ burning jet fuel, which along with the initial damage to the buildings’ structural columns, ultimately caused both towers to collapse.

How many people did it killed and how it looked after?

It killed about 3000 people.
