0 Twin Beams Of Light Mark Where The World Trade Centre Once Stood.
Twin beams of light reaching toward heaven, that's how many relatives and friends see the Points of Light at Ground Zero. The lights mark the footprints of the World Trade Center, where the twin towers once soared over the Manhattan skyline. They also pay tribute to the people who died that Tuesday morning six years ago. Tuesday night's display marks the end of a daylong gathering of family members, friends and former co-workers whose lives changed when terrorists destroyed the World Trade Center and killed nearly three-thousand people. The lights faded at dawn.
