Two powerful beams of light in the sky became a tribute to those who lost their lives on 9/11

In 2001 on September 11, there was an air attack on the World Trade Center. On that day, 17 years ago, 3000 people lost their lives.

This year, the anniversary was commemorated in Lower Manhattan, New York. Two beams of light shined in the night sky for all to see.

On September 11, the “Tribute in Light” installation was dedicated to those who died during the attack on the World Trade Center in 2001. The tribute was in its 17th year.

The lights were made to reach up to 4 miles in height and are made of 887,000-watt xenon light bulbs. They only faded away on Wednesday.

They were positioned that way to resemble the shape of the Twin Towers. The installation was sponsored by the Carnegie Corporation of New York.

In March 2002, the “Tribute in Light” made its debut according to Time Out. At first, the lights were placed in a vacant lot across from ground zero, but they were moved to the roof of a nearby parking garage.

They were said to be so bright, that they've disrupted the flight patterns of migrating birds. The National September 11 Memorial and Museum hosted the annual ceremony in remembrance of the victims of the 2001 and 1993 World Trade Center attacks.

The event started at 8:39 a.m. At the time, family members of those who died began reading the victims' names at the World Trade Center's Memorial Plaza.

There were six pauses during the readings to mark when each plane struck the towers, when each tower collapsed, when the plane hit the Pentagon, and when Flight 93 crashed in Pennsylvania.

The facility was closed to the public until Tuesday afternoon to allow the families of those killed to remember their loved ones. The Plaza was kept open to the public from 3 p.m. to midnight.

President Donald Trump and his wife First Lady Melania Trump attended the annual observance at the Flight 93 National Memorial near Shanksville, Pennsylvania. There the new Tower of Voices monument was dedicated over the weekend.

The ceremony was free and open to the public. In turn, Vice President Mike Pence attended the annual ceremony at the Pentagon Memorial in Arlington, Virginia.

There he honored the 184 people who died when American Airlines Flight 77 crashed into the Pentagon on September 11, 2001. This ceremony was not open to the public.

On the morning of September 11, 2001, hijackers took control of four planes and crashed them into New York’s World Trade Center towers. The planes also crashed into the Pentagon in Arlington County and a field in Shanksville.
