List of tenants in 1 World Trade Center (1971–2001)

The original One World Trade Center (also known as the North Tower, Tower 1, Building One, or 1 WTC) was one of the Twin Towers of the original

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 succeeded 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.^[4][5]

92nd floor

The 92nd floor, though technically the first floor below Flight 11's impact zone, did not have any survivors.^[9] Sixty-nine people reported to work that morning, including 67 employees of Carr Futures, a tenant on the 92nd floor. The impact itself spared every single person on Floor 92 and did no damage to the floor directly. However, the force of the crash collapsed walls and inflicted nonstructural damage such as smashed windows,^[10] broken ceiling tiles and severed electrical wires, as well as causing knee-deep flooding throughout various rooms on the 92nd floor after the water pipes burst. Multiple calls were recorded from people trapped on the floor, the workers reporting that although the stairs on the 92nd floor had not been destroyed, they were walled off by fallen debris from Flight 11's impact zone immediately above.^[11] In addition to the stairs being rendered impassable, the centralized impact into the North Tower's core also interrupted elevator service in the skyscraper from its 50th floor and higher, severing all escape routes for anyone above the 91st floor.^[12]

Initially, conditions on the 92nd floor were likely not dissimilar to what they were on the 91st, from which everyone survived and escaped.^[13] The situation changed very quickly when flammable aviation fuel spilled down into the 92nd floor, igniting fires that rapidly began consuming its east side; within 12 minutes of the impact, the first known fatalities from the floor occurred over a three-minute period when eight workers were forced to jump from the northern end of the tower's east side to escape a rapidly advancing wall of flames.^[14] Those who remained made their way to an unoccupied area on the west side of the floor that was initially free of smoke and fire. However, images show that the blaze on the tower’s north face eventually spread westward to their safe haven in that section of the floor, making conditions there unsurvivable.^[15]

The last phone call from the North Tower came from Thomas McGinnis, a trader on the 92nd floor, when he got through to his wife Iliana at 10:18. McGinnis and a number of others had been confined to a conference room the entire time after the door jammed shut from the building buckling as the plane hit, separating them from everyone else on the floor. Most of the floor was engulfed in flames by the time McGinnis called, with extremely limited space for the group to avoid being burned.^[16] Despite his wife's attempts to reassure him, McGinnis did not believe they would survive. The South Tower had already collapsed, and McGinnis revealed to her that he could see people jumping from the floors above. The line went dead at 10:26, two minutes before the tower collapsed.^[17]
