On the morning of Sept. 11, 2001, Dora Menchaca, an associate director of clinical research at Amgen Inc., boarded American Airlines Flight 77 to Los Angeles.
Her flight home was cut tragically short when terrorist hijackers crashed her plane into the Pentagon.
On the same day, Karleton Fyfe, a senior analyst at John Hancock, boarded American Airlines Flight 11. His flight was the first of two planes to crash into the World Trade Center.
In the north tower, where the first plane hit at 8:45 a.m., Ryan Kohart was going through his day as an equities trader for the firm Cantor Fitzgerald.
Andrew King was also in that building, carrying out his duties as president of the company's ESpeed desk. Neither man knew that the tower would collapse at 10:28 a.m.
In the south tower, hit by United Airlines Flight 175 from Boston at 9:03 a.m., Christopher Quackenbush oversaw the day's developments at Sandler O'Neill, an investment banking firm he helped to establish.
A few floors below him, Mary Lou Hague was working as a financial analyst at the investment banking firm Keefe, Bruyette, and Woods when the building collapsed at 10:05 a.m., clouding lower Manhattan with dust and debris.
All six victims of the Sept. 11, 2001 attacks were UNC alumni.
On Tuesday, members of the class of 2005 voted to construct a 9/11 memorial garden in honor of the alumni as their senior gift to the University. Planning is already underway.
