It was distinguishable from its twin, the original 2 World Trade Center, also known as the South Tower, by the 110.3-metre (362 ft) telecommunications antenna on its roof. Including the antenna, the building stood at a total height of 1,730ft (527,3m). Other things that made the North Tower distinguishable from its twin was that there was a canopy connected to the North Tower's west facade on street level and there were two small pedestrian walkways that extended from the west and south promenades of Three and Six World Trade Center to the North Tower's north and south facades on plaza level, while the South Tower lacked any of those. The building's address was 1 World Trade Center, and the WTC complex had its own ZIP code (10048) due to its large size.
The original World Trade Center was destroyed in the terrorist attacks of September 11, 2001. Struck by American Airlines Flight 11 at 8:46 a.m., the North Tower was the first of the Twin Towers to be hit by a hijacked aircraft, and the second to collapse, at 10:28 a.m. The North Tower stood for 102 minutes after the aircraft impact. Of the 2,977 victims killed in the attacks, around 1,600 were in the North Tower or on the ground.
The North Tower was replaced by the present-day One World Trade Center tower, which was opened in November 2014 as the lead building of the redeveloped World Trade Center site.[3][4]

92nd floor
The 92nd floor, though intact and below the initial impact, did not have any survivors. Several 911 calls were recorded from employees at Carr Futures, a tenant on the 92nd floor. The workers reported that the elevators were destroyed and the stairwells impassable. A number of employees in a meeting were trapped in a conference room when its door jammed shut from the crash; the remainder made their way to an unoccupied area on the west side of the floor initially free of smoke and flames. However, by the time the North Tower collapsed at 10:28 AM, fire had spread to that part of the floor, making conditions there unsurvivable. The last 911 call from that floor came from Tom McGinnis at 10:26 AM.[8][9]
Tenants that left prior to the attacks
Between 1978 and 1995, the Consulate of Paraguay was located in Suite 1609 of 1 World Trade Center.[10][11] Home Lines once occupied Suite 3969.[12]
