Two world trade center
WTC towers refers to the twin towers at the World Trade Center in New York City.
The number who jumped or fell from the Twin Towers is believed to be about 200.
No, the second tower (the one which was hit by the second plane) collapsed a few minutes after the first tower.
If the WTC towers did not collapse, they would eventually be due to the extensive damage beyond repair
They are identical. (Edit: The twin towers were two buildings: WTC 1 and WTC 2. The World Trade Center was actually a complex of buildings, rather than simply one. I believe there were seven buildings that were a part of the complex, but none of them were quite as prominent as the twin towers. )
The Twin Towers of the World Trade Center fell in a specific order on September 11, 2001. The South Tower (WTC 2) was struck by American Airlines Flight 175 at 9:03 AM and collapsed first at 9:59 AM. The North Tower (WTC 1), hit by United Airlines Flight 11 at 8:46 AM, collapsed later at 10:28 AM.
The North Tower (1 WTC) was impacted at 8:46 AM and fell at 10:28 AM, standing for 102 minutes after American Airlines Flight 11 hit. The South Tower (2 WTC) was hit at 9:03 AM and fell at 9:59 AM, a mere 56 minutes after impact.
On September 11, 2001, three buildings of the World Trade Center complex collapsed due to the terrorist attacks. The Twin Towers, known as WTC 1 and WTC 2, both collapsed after being struck by hijacked planes. Additionally, WTC 7, a nearby building, collapsed later that day due to fire and structural damage. In total, three buildings in the WTC complex fell that day.
The explosions caused by airplanes impacting the World Trade Center towers first caused huge holes in the respective north and south faces of 1 WTC and 2 WTC. The fire started by the explosions, combined with the damage to floor beams and inner support structures, weakened the towers to the point of collapse.
The height of WTC 1 was 1,368 ft (417 meters) and WTC 2 was 1,362 ft (415 meters)
The WTC has been attacked twice. Once in 1993, with a bomb that didn't do much damage, and in September 2001, which brought the Towers down.
The WTC is known as "The Twin Towers"
