*Now in its 12th year, the Tribute in Light sent two high-intensity beams of light four miles up into the night sky in a poignant memorial marking the absence of the original Twin Towers.
*Several dozen onlookers including victimsâ family members and city officials watched the beams emanate from the top of a parking structure just blocks from Ground Zero in a solemn expression of remembrance.
* “It is a symbol of New York and of the resilience of New Yorkers after the attack.â said Ryan Pawling, assistant director for public programs at the 9/11 Memorial.
*Designers included John Bennett, Gustavo Bonevardi, Richard Nash Gould, Julian Laverdiere, and Paul Myoda with lighting consultant Paul Marantz. MAS continued the show annually through the tenth anniversary in 2011.
*The technology behind the Tribute in Light and skill required to pull it off are as impressive as the display itself.
*Pawling said each cannon had to be individually alignedâbeginning with the corners of each of the squares — to ensure the light beams point directly skyward with one unified glow.
*The cannons were adjusted fractions of a degree using specialized mounting gear that miles up in the sky accounts for a wide berth. If the lights are not all in sync, the beacons would appear fuzzy from far away.
*While the official Tribute in Light was only one night, New Yorkers for miles around could see the beams at night as crews traveled ten to fifteen miles away in several directions to ensure the beacons were plumb.Source: blog of archpaper | Credits: BRANDEN KLAYKO | EAST | THURSDAY, SEPTEMBER 12, 2013
