How many terrorists were on the second plane to hit the World Trade Center?
United Airlines Flight 175 United Airlines Flight 175 was a scheduled domestic passenger flight from Logan International Airport, in Boston, Massachusetts, to Los Angeles International Airport, in Los Angeles, California. On September 11, 2001, the Boeing 767-200 operating the route was hijacked by five al-Qaeda terrorists and flown into the South Tower of the World Trade Center in New York City, killing all 65 people aboard and an unconfirmed number in the building's impact zone.
Survivors' Staircase The Survivors' Staircase was the last visible remaining original structure above ground level at the World Trade Center site. It was originally two outdoor flights of granite-clad stairs and an escalator that connected Vesey Street to the World Trade Center's Austin J. Tobin Plaza. During the September 11 attacks, the stairs served as an escape route for hundreds of evacuees from 5 World Trade Center, a 9-floor building adjacent to the 110-story towers. The staircase is now an important feature of the National September 11 Memorial & Museum.
