Dozens of firefighters, family, friends and neighbors bid farewell to an FDNY hero Wednesday.

Public visitation for firefighter William Moon II began at 2 p.m. at Chapey Funeral Home in East Islip.

The 47-year-old father of two died of a brain injury during a training accident at a Brooklyn fire house.

"He was probably one of the most incredible firemen that I've ever met," said FDNY Capt. Pat Connolly. "He was so good at his job that it made my job much easier. We lost one of the best people that ever wore our uniform and I mean that from the bottom of my heart."

Connolly said Moon's first priority was helping others. Now, he says the department's priority is to come together to help Moon's family.

Moon, who also volunteered with the Islip Fire Department, saved five other lives through organ donations.

A funeral will take place on Thursday at St. Patrick's Church in Bay Shore beginning at 11 a.m.
