WTC towers refers to the twin towers at the World Trade Center in New York City.
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 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"
Two world trade center
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 World Trade Center Twin Towers were office buildings that leased office space to many businesses both large and small. The link below states that 'WTC documents indicate from 435 to 500 businesses were housed in the WTC Twin Towers' and includes a list of tenants known to that organization.
One World Trade Center is currently under construction at the former WTC site. Construction has started on three more office towers one block east of where the original towers were.
The people running from ground zero as the towers collapsed. Sheer pandemonium and panic.
The number who jumped or fell from the Twin Towers is believed to be about 200.
Yes, the North Tower (also referred to as 1 WTC) was the second of the towers to collapse.
