Katherine McGarry Noack was at the top of one of the World Trade Center towers, attending a conference, when terrorists struck 15 years ago. Noack's new husband, Brad, worked at the World Trade Center.

They were in different areas of the twin towers complex that day. He made it out. She was at the top of the north tower and knew she couldn't escape. In her last phone call she asked him to tell her family she loved them.

"She mentioned to him the thick smoke and the fact that they were trapped," said her sister Marianne Burke. "She feared they would not be able to escape. She asked Brad to tell us that she loved us. Brad did escape and outside when the towers fell."

Katherine was 30. Her remains were never recovered.

"Although it's been 15 years, sometimes it feels like yesterday," Burke said.

Burke shared the painful memory at a sunrise service Sunday morning at Kennesaw Mountain. On Saturday, volunteers organized by the Marietta Kiwanis club placed nearly 3,000 flags in memory of the victims who died in the Sept. 11, 2001 terrorist attacks. See the video of the flag installation here.

"The horror of that day is difficult to remember but it also reminds me of the love and support that we have received from family, friends and the Marietta community over the past 15 years," she said. "This fields of flags .. is a wonderful tribute to each and every victim that died that day and also those that continue to defend this great nation and our freedom."

Sunday's event included remarks from former Georgia Gov. Roy Barnes, U.S. Sen. Johnny Isakson and former U.S. Rep. Bob Barr, who all live in Cobb County.

"Fifteen years ago today, on a morning just like today, 19 radical Islamic terrorists hijacked four American domestic airliners and attacked New York City and Washington D.C. in what I've called the first battle in the war between good and evil," Isakson said. Referencing more recent terrorist attacks including the mass shootings in  Orlando, San Bernardino, Calif., Fort Hood, Brussels and Paris, he said, "We are in a full-scale war that we must win."

Barnes and Barr spoke of American resolve in times of adversity.

The event featured a military flyover a 21-gun salute and the reading of all of the victims of 9-11, including Katie MGarry Noack's. Here is a video clip of her sister's remarks:
