A man walks past as the Tribute in Light is illuminated on the skyline of lower Manhattan during events marking the 13th anniversary of the 9/11 attacks on the World Trade Center in New York, September 10, 2014. Until a few months ago, the part of New York City where crowds will gather on Thursday morning to mark the 13th anniversary of the September 11 attacks on the U.S. had been mostly fenced off to the public. This year, for perhaps the first time since the attacks, a sense of normalcy and openness has taken root in the city blocks where two airliners hijacked by militants from al Qaeda crashed into the World Trade Center’s twin towers.
