query: At what time did the first tower of the World Trade Center fall on September 11?
passage: Collapse of the World Trade Center
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]
passage: Windows on the World
Windows on the World was destroyed when the North Tower collapsed during the terrorist attacks of September 11, 2001. That morning, the restaurant was hosting regular breakfast patrons and the Risk Waters Financial Technology Congress. World Trade Center lessor Larry Silverstein was regularly holding breakfast meetings in Windows on the World with tenants as part of his recent acquisition of the Twin Towers from the Port Authority, and was scheduled to be in the restaurant on the morning of the attacks. However, his wife insisted he go to a dermatologist's appointment that morning, whereby he avoided death. Everyone present in the restaurant when American Airlines Flight 11 penetrated the North Tower perished that day, as all stairwells and elevators leading to below the impact zone were destroyed immediately. Victims trapped in Windows on the World died either from smoke inhalation from the fire, jumping or falling from the building to their deaths, or the eventual collapse of the North Tower 102 minutes later.
