The September 11th National Memorial Museum preview site in Lower Manhattan will unveil Wednesday a collection of almost 600 audio recordings from families and friends of the terrorist attacks' victims.

The listening station at 20 Vesey Street will also features remembrances of people who experienced the 2001 terrorist attacks firsthand.

Visitors will be able to hear the stories and record their own memories in a separate booth, and many of the recordings will become part of the museum's permanent archives.

One recording comes from Dianne DeFontes, a woman who worked on the World Trade Center on the morning of the attack.

"I was on the 89th floor of the World Trade Center [on] September 11th and I am a survivor. And I remember what an absolutely beautiful day it was," DeFontes says. "The sky was that beautiful blue, there were very few clouds. When I got into my office I took one last look at the window and went to my desk. Then all of a sudden this bang happened. The bang and being thrown out of my chair and having the door partially open, it like all happened at the same time."

Brooklyn resident Richard Pecorella shares how he met his fiancee Karen Juday at a car race in 1996. Five years later, Juday was killed in the World Trade Center attack.

"I knew as soon as I looked at he she was the one. It was magical, I can't describe it," says Pecorella about the first meeting.

There are also stories from first responders who performed jobs under extraordinary circumstances.

"You wanted to hear, 'They found a cluster, we've got 10 coming in one ambulance, we're ready.' When that stopped, that was very hard," says St. Vincent's Hospital nursing supervisor Francine Kelly.

September 11th National Memorial President Joe Daniels said the exhibit serves as an educational resource for those wanting to learn more about the attacks.

"The fact that 9/11 happened to happen during a time of incredible technology gives us the opportunity to do this oral history project, to talk to the very people who were there or who knew the victims," said Daniels. "In a way, we'd love to have recordings from 2,000 years ago from major historical events, but [now] we're going to get a recording from every victim."

Meanwhile, the Port Authority announced Monday that the two signature reflecting pools for the September 11th National Memorial at the World Trade Center site are completely framed in steel.

The completed memorial will contain about 8,100 tons of steel, which is more than in the Eiffel Tower.

The reflecting pools, which are situated in the footprints of the original Twin Towers, will pump 52,000 gallons of recycled water per minute.

The memorial is scheduled to open by the 10th anniversary of the attacks and the museum is set to open on September 11, 2012.

The preview site is free to the public and located across from the site of the permanent memorial. For more information, visit national911memorial.org.
