Police say a 29-year-old woman plunged about 30 feet to her death off an escalator inside the famed World Trade Center Oculus. They say she was apparently trying to retrieve a hat while on the escalator with her twin sister at about 5:30 a.m. today inside the lofty transit hub. She fell to the main concourse floor. Port Authority police spokesman Joseph Pentangelo said the woman was taken to a hospital where she was pronounced dead. Police are investigating the incident. Her name hasn’t been released. The striking USD 3.9 billion transportation hub was designed by architect Santiago Calatrava and provides connections between New Jersey’s PATH trains and New York City’s subways and contains a shopping mall. It’s also a major tourist attraction.
