Two workers have been rescued from a malfunctioning platform on a luxury high-rise 40 stories above lower Manhattan, a frightening incident that brought the area near West and Murray streets to a halt as the morning rush peaked on Friday. No one was injured in the mishap around 8:30 a.m. at a building under construction on Murray Street, about 10 blocks from the World Trade Center. It's not immediately clear what went wrong with the platform. An NYPD official tweeted that the device was around the 40th floor. Chopper 4 showed nearly a half-dozen fire and emergency vehicles near the scene. An empty scaffolding was seen hanging on the side of the building, several firefighters near a broken window inside.
