The American flag that was hoisted by firefighters amid the wreckage of the World Trade Center on 9/11 will be returned to lower Manhattan, where it will be displayed at the National September 11 Memorial & Museum.

An image of the firefighters raising the flag was captured by a photographer for The Record, a New Jersey newspaper, on the day of the tragedy.

After a long search, The History Channel claims to have found the flag, according to The New York Times.

“There was a lot of work to determine if it was the Ground Zero flag,” a senior historian at the network told the Times.
