Twenty-one years after the Sept. 11 terror attacks, a photo of a group of White Plains firefighters is being shared with the public for the very first time.

Retired Lt. John Donahoe, now 70, and a group of nine others from Station 2 took a Metro-North train to help assist with efforts to find human remains.

"A whistle blew and that meant that FDNY had found one of their 343, either body or body parts, which was a signal to all outside agencies to leave the area out of respect," Donahoe recalled.

"It was during that short break this photo was taken," he added.

Donahoe says nine of the 10 firefighters who responded with him are now retired.

Then-firefighter Vinnie Wadden is still with the department, and now serves as lieutenant.
