Query: At what time did the first tower of the World Trade Center fall on September 11?
The Twin Towers of New York City's World Trade Center collapsed after being deliberately struck by two commercial passenger jets during the September 11 attacks. A total of four commercial aircraft were hijacked by al-Qaeda terrorists on 9/11 and two of those were crashed into the Twin Towers.[1] American Airlines Flight 11 was crashed into the north side of the North Tower (One World Trade Center) and United Airlines Flight 175 was crashed into the south side of the South Tower (Two World Trade Center).[2] The collapse of the Twin Towers destroyed the rest of the complex, and debris from the collapsing towers severely damaged or destroyed more than a dozen other adjacent and nearby structures. The South Tower collapsed at 9:59am, less than an hour after being hit, followed by the North Tower at 10:28am. Later that day, the nearby Seven World Trade Center collapsed at 5:21pm from fires that had started when the North Tower collapsed.[3] As a result of the attacks to the towers, a total of 2,763 people died including 2,192 civilians, 343 firefighters, and 71 law enforcement officers as well as all the passengers and crew on the airplanes, including 147 civilians and the 10 hijackers.[4]
Glens Falls is also home of The Glens Falls September 11 Memorial, on the May Street side of the Glens Falls Fire Department headquarters at 134 Ridge Street. The memorial is a tribute to the lives lost on that day as well as a tribute to all first responders involved in rescue efforts at the World Trade Center and the Pentagon. The memorial consists of 12 foot, solid granite towers resembling the trade center encompassed by granite walls to resemble the Pentagon. It also incorporates a piece of steel from the World Trade Center on permanent loan from the NY/NJ Port Authority.
The original World Trade Center was destroyed in the terrorist attacks of September 11, 2001; One World Trade Center was the first of the famous Twin Towers to be struck by a hijacked aircraft, at 8:46 a.m EDT, and the second tower to collapse, at 10:28 a.m. Of the 2,977 victims killed in the attacks, 1,402 were in or above the North Tower impact zone. 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.
Swann has questioned whether 7 World Trade Center collapsed on September 11, 2001, the way authorities said it did. See also 9/11 conspiracy theories. The National Institute of Standards and Technology  (NIST) investigated the events of 7 World Trade Center. NIST determined that diesel fuel did not play an important role, nor did the structural damage from the collapse of the Twin Towers. Fires burned out of control during the afternoon, buckling critical columns, and ultimately causing the building to fall downward as a single unit. The fires, which were fueled by office contents and burned for seven hours, along with the lack of water, were the key reasons for the collapse. This made the old 7 WTC the only steel skyscraper at the time to have collapsed from fire. The NIST report found no evidence supporting the conspiracy theories that 7 World Trade Center was brought down by controlled demolition. 
On September 11, 2001, two of the four hijacked planes were flown into the Twin Towers of the original World Trade Center, and the towers collapsed. The 7 World Trade Center was not struck by a plane, but collapsed because of heavy debris falling from the impacts of planes and the collapse of the North Tower. The other buildings of the World Trade Center complex were damaged beyond repair and soon after demolished. The collapse of the Twin Towers caused extensive damage to surrounding buildings and skyscrapers in Lower Manhattan, and resulted in the deaths of 2,606 people, in addition to those on the planes. Many rescue workers and residents of the area also developed several life-threatening illnesses and some have since died.
The original World Trade Center was a large complex of seven buildings in Lower Manhattan, New York City, United States. It featured the landmark Twin Towers, which opened on April 4, 1973 and were destroyed in 2001 during the September 11 attacks. At the time of their completion, the Twin Towers — the original 1 World Trade Center, at ; and 2 World Trade Center, at — were the tallest buildings in the world. Other buildings in the complex included the Marriott World Trade Center (3 WTC), 4 WTC, 5 WTC, 6 WTC, and 7 WTC. The complex was located in New York City's Financial District and contained of office space.
This just in. You are looking at obviously a very disturbing live shot there. That is the World Trade Center, and we have unconfirmed reports this morning that a plane has crashed into one of the towers of the World Trade Center. CNN Center right now is just beginning to work on this story, obviously calling our sources and trying to figure out exactly what happened, but clearly something relatively devastating happening this morning there on the south end of the island of Manhattan. That is once again, a picture of one of the towers of the World Trade Center.
On September 11, 2001, two of four hijacked planes were flown into the Twin Towers of the original World Trade Center in Lower Manhattan, and the towers collapsed. 7 World Trade Center also collapsed due to damage from fires. The other buildings of the World Trade Center complex were damaged beyond repair and demolished soon thereafter. The collapse of the Twin Towers caused extensive damage and resulted in the deaths of 2,753 victims, including 147 aboard the two planes. Since September 11, most of Lower Manhattan has been restored. In the years since, many rescue workers and residents of the area have developed several life-threatening illnesses, and some have died.
On September 11, 2001, two of four hijacked planes were flown into the Twin Towers of the original World Trade Center, and the towers subsequently collapsed. 7 World Trade Center collapsed due to fires and structural damage caused by heavy debris falling from the collapse of the Twin Towers. The other buildings within the World Trade Center complex were damaged beyond repair and soon after demolished. The collapse of the Twin Towers caused extensive damage to other surrounding buildings and skyscrapers in Lower Manhattan, and resulted in the deaths of 2,606 people, in addition to those on the planes. Since 2001, most of Lower Manhattan has been restored, although there has been controversy surrounding the rebuilding. Many rescue workers and residents of the area developed several life-threatening illnesses that have led to some of their subsequent deaths. A memorial at the site was opened to the public on September 11, 2011, and the museum opened in 2014. In 2014, the new One World Trade Center, at and formerly known as the Freedom Tower, became the tallest building in the Western Hemisphere, while other skyscrapers were under construction at the site.
9/11: The Twin Towers (also billed as Inside the Twin Towers) is a television special documentary film which uses re-enactments and computer-generated imagery to re-create a minute-by-minute account of what happened inside the twin towers of the World Trade Center in New York City during the September 11 attacks. In the United States it premiered on the Discovery Channel on 3 September 2006, narrated by Harry Pritchett. In the United Kingdom it premiered on BBC One on 7 September 2006, narrated by Terence Stamp.
The original 4 World Trade Center was a 9-story low-rise office building that was completed in 1975 that was 118 ft (36 m) tall and in the southeast corner of the site, in Lower Manhattan, New York City. The building's major tenants were Deutsche Bank (Floor 4, 5, and 6) and the New York Board of Trade (Floors 7, 8, and 9). The building's side facing Liberty Street housed the entrance to The Mall at the World Trade Center on the basement concourse level of the WTC. It was practically destroyed as a result of the collapse of the South Tower during the September 11 attacks and its remains were later demolished to make way for the construction of the new skyscrapers, Four World Trade Center and Three World Trade Center. 4 World Trade Center was home to five commodities exchanges on what was at the time one of the world's largest trading floors (featured in the Eddie Murphy movie "Trading Places").
After years of delay and controversy, reconstruction at the World Trade Center site started. The new complex includes One World Trade Center, 3 World Trade Center, 4 World Trade Center, 7 World Trade Center, and one other high-rise office building being planned at 2 World Trade Center. The new World Trade Center complex also includes a museum and memorial, and a transportation hub similar in size to Grand Central Terminal. 7 World Trade Center opened on May 23, 2006, making it the first of five skyscrapers to have been completed in the World Trade Center complex. 4 World Trade Center, the first building completed as part of the site's master plan, opened on November 12, 2013. The National September 11 Museum opened on May 21, 2014, and the memorial opened on September 11, 2011. One World Trade Center was opened on November 3, 2014. The World Trade Center Transportation Hub opened to the public on March 4, 2016, and 3 World Trade Center opened on June 11, 2018. 2 World Trade Center's full construction was placed on hold in 2009, with a new design announced in 2015.
Gage criticized NIST for not having investigated the complete sequence of the collapse of the World Trade Center towers, and claims that "the official explanation of the total destruction of the World Trade Center skyscrapers has explicitly failed to address the massive evidence for explosive demolition." In particular, Gage argues that the buildings of the World Trade Center could not have collapsed at the speed that has been observed without tearing apart several columns of their structures with the help of explosives. To support its position, Architects & Engineers for 9/11 Truth points to the "free fall" acceleration of 7 WTC during part of the collapse, to "lateral ejection of steel," and to "mid-air pulverization of concrete." Gage also said that the absence of "large gradual deformations" associated with the collapse would indicate that the buildings have been destroyed by controlled demolition. That the three buildings of the World Trade Center "fell through what should have been the path of greatest resistance" would, according to the organization, require "precisely timed removal of critical columns, which office fires cannot accomplish". As the mass of the top of the North Tower had been blown outward during the collapse, there was "nothing left to drive this building to the ground," Gage says.
The local, state, federal and global reaction to the September 11 attacks on the World Trade Center was unprecedented. The equally unsurpassed events of that day elicited the largest response of local emergency and rescue personnel to assist in the evacuation of the two towers and also contributed to the largest loss of the same personnel when the towers collapsed. After the attacks, the media termed the World Trade Center site "Ground Zero", while rescue personnel referred to it as "the Pile".
After the 1993 World Trade Center bombing, radio repeaters for New York City Fire Department communication were installed in the tower complex. Because they were unaware that several controls needed to be operated to fully activate the repeater system, fire chiefs at their command post in the lobby of the North Tower thought the repeater was not functioning and did not use it, though it did work and was used by some firefighters. When police officials concluded the twin towers were in danger of collapsing and ordered police to leave the complex, fire officials were not notified. Fire officials on the scene were not monitoring broadcast news reports and did not immediately understand what had happened when the first (South) tower did collapse. 
Tom Kaminski: Alright uh, Pat, we are just currently getting a look...at the World Trade Center, We have something that has happened here at the World Trade Center. We noticed flame and an awful lot of smoke from one of the towers of the World Trade Center. We are just coming up on this scene, this is easily three-quarters of the way up...we are...this is...whatever has occurred has just occurred, uh, within minutes and, uh, we are trying to determine exactly what that is. But currently we have a lot of smoke at the top of the towers of the World Trade Center, we will keep you posted.
One of the first memorials was the "Tribute in Light", an installation of 88 searchlights at the footprints of the World Trade Center towers. In New York City, the World Trade Center Site Memorial Competition was held to design an appropriate memorial on the site. The winning design, "Reflecting Absence", was selected in August 2006, and consists of a pair of reflecting pools in the footprints of the towers, surrounded by a list of the victims' names in an underground memorial space. The memorial was completed on September 11, 2011; a museum also opened on site on May 21, 2014.
After American Airlines Flight 11 crashed into the North Tower (1 WTC) of the World Trade Center, a standard announcement was given to tenants in the South Tower (2 WTC) to stay put and that the building was secure. However, many defied those instructions and proceeded to evacuate the South Tower (most notably, Rick Rescorla, Morgan Stanley Security Director, evacuated 2687 of the 2700 Morgan Stanley employees in the building). All people evacuating were ordered through a door on the mezzanine level that led to a bridge to another building, and everyone was evacuated through the neighboring building. The firefighters in charge did not want anyone going through the front doors at first due to falling debris, and then because of falling people who had jumped from the towers.
A memorial to the victims of the September 11, 2001 attacks, built on the pedestrian promenade of the Baltimore World Trade Center between the building and Pratt Street, was dedicated on September 11, 2011,
the tenth anniversary of the attacks. The memorial structure includes three 22-foot long steel beams from the New York World Trade Center, which were part of the 94th to 96th floors of the north
tower. Twisted and fused together, the steel beams and damaged limestone pieces from the Pentagon’s west wall rest atop marble blocks bearing the names and birthdays of the 68 Marylanders who died in the 9/11 terrorist attacks. Windows on the top floor of the Baltimore World Trade Center are marked with all of the names of the September 11 attack victims.
In the United States, since the film was released on September 28, 2001 (about two weeks after the 9/11 attacks on the World Trade Center), Stiller made the executive decision to digitally remove any backgrounds that originally contained the Twin Towers in the background skyline. Stiller defended his decision to erase images of New York's World Trade Center Towers from the film, saying he did what he thought was appropriate at the time.
The address of this building was 2 World Trade Center with the WTC complex having its own ZIP code of 10048. It was destroyed along with the North Tower (1 World Trade Center) in the September 11 attacks. The South Tower was the second tower to be struck, at 9:03 a.m., and the first tower to collapse, at 9:59 a.m. Of the 2,977 victims killed in the attacks, 614 were in or above the South Tower impact zone. At the National September 11 Memorial & Museum, the southern pool marks the spot where the South Tower stood.
The command post located across West Street was taken out when the South Tower collapsed, making command and control even more difficult and disorganized. When the North Tower collapsed, falling debris killed Peter Ganci, the FDNY chief. Following the collapse of the World Trade Center, a command post was set up at a firehouse in Greenwich Village.
One World Trade Center (also known as One WTC, 1 World Trade Center, 1 WTC, or Freedom Tower) is the main building of the rebuilt World Trade Center complex in Lower Manhattan, New York City. One WTC is the tallest building in the United States, the tallest building in the Western Hemisphere, and the sixth-tallest in the world. The supertall structure has the same name as the North Tower of the original World Trade Center, which was destroyed in the terrorist attacks of September 11, 2001. The new skyscraper stands on the northwest corner of the World Trade Center site, on the site of the original 6 World Trade Center. The building is bounded by West Street to the west, Vesey Street to the north, Fulton Street to the south, and Washington Street to the east.
Following the attacks, plans were announced to rebuild the World Trade Center site. 7 World Trade Center became the first World Trade Center skyscraper to be rebuilt in five years after the attacks. One World Trade Center, four more office towers, and a memorial to the casualties of the September 11 attacks are under construction as of 2011. One World Trade Center opened on November 3, 2014.
Six World Trade Center, building 6 of the World Trade Center in New York City was a U.S. Customhouse. It was completed in 1972 at a height of 105 ft (32 m). It was heavily damaged during the September 11, 2001 attacks by the collapse of the North Tower at 10:28 a.m. EDT and later demolished in December 2001.
The following is a list of tenants of 6 World Trade Center prior to the September 11, 2001 attacks:
