Respiratory hospital admissions increased significantly among lower Manhattan residents the first week after 9/11 compared with a similar demographic in Queens. Cardiovascular and cerebrovascular disease admissions also increased two to three weeks after 9/11, especially among women and those over 65 years of age.
After 9/11, all passengers 18 years or older must now have valid, government-issued identification in order to fly. Airports may check the ID of any passenger (and staff member) at any time to ensure the details on the ID match those on the printed boarding pass.
The 9/11 terrorist attacks on America caused significant economic damage in the immediate aftermath, rippling through global financial markets. Airlines and insurance companies took the hardest immediate hit, and U.S. stock markets initially fell more than 10% in the days after.
Logan International Airport
Early on the morning of Septem, 19 hijackers took control of four commercial airliners (two Boeing 757s and two Boeing 767s) en route to California (three headed to LAX in Los Angeles and one to SFO in San Francisco) after takeoffs from Logan International Airport in Boston, Massachusetts; Newark Liberty …
At the end of the process $7 billion was awarded to 97% of the families. A non-negotiable clause in the acceptance papers for the settlements was that the families were to never file suit against the airlines for any lack of security or otherwise unsafe procedures.
200 people
Last Elevator Down Michael Nestor, Liz Thompson and Richard Tierney were three of the four passengers on the last elevator down from Windows on the World. Everybody who was at Windows on the World at the time of impact on Sept. 11 — approximately 170 men and women — perished.
Of the 2,977 victims killed in the September 11 attacks, 412 were emergency workers in New York City who responded to the World Trade Center. This included: 343 firefighters (including a chaplain and two paramedics) of the New York City Fire Department (FDNY);
9:59 a.m.: The south tower of the World Trade Center collapses 56 minutes after being hit by Flight 175. The collapse, which lasted 10 seconds, killed over 800 people and first responders inside the building and the surrounding area.
In addition, the south tower, though hit second, collapsed first, just 57 minutes after being struck, before deterioration had spread as widely. In both towers, the people and debris that fell forced officials to reroute the evacuation, away from the plaza between the buildings.
9:59 am
One World Trade Center (WTC 1) (the North Tower) was hit at 8:46 a.m. Eastern time and collapsed at 10:28 a.m. Two World Trade Center (WTC 2) (the South Tower) was hit at 9:03 a.m. and collapsed at 9:59 a.m.
Engineers suggested that the south tower of the World Trade Center collapsed first, even though it was hit by the second plane, because the fireball caused by the crash was larger and because the plane hit the corner of the building, rather than the center, where there is more structural support.
According to a theory advanced by a materials scientist in Norway, a mixture of water from sprinkler systems and molten aluminum from melted aircraft hulls created explosions that led to the collapse of the World Trade Center’s Twin Towers in Manhattan on Sept. 11, 2001.
Nineteen al-Qaeda terrorists hijacked four US passenger airplanes. Between at 8 and 9 am, two of the planes crashed into the twin towers of the World Trade Center complex in Manhattan. Within two hours, both the 110-storey towers collapsed.
The analysis shows that if prolonged heating caused the majority of columns of a single floor to lose their load carrying capacity, the whole tower was doomed. Despite optimistic simplifying assumptions, the structural resistance is found to be an order of magnitude less than necessary for survival.
