Paul "Paulie" Veneto, a former flight attendant, is pushing an airline beverage cart over 200 miles from the Boston Public Garden 9/11 Memorial to the National 9/11 Memorial and Museum at Ground Zero.

Veneto's poignant journey honors the bravery of his colleagues, including nine close friends, who lost their lives on American Flight 11.

As of today, Veneto has approximately 13 miles remaining in his tribute.

"I'm doing this in honor and memory of the heroes of American Flight 11," Veneto said, remembering his colleagues who perished in the World Trade Center's South Tower.
