13 children of firefighters who died in 9/11 graduate from FDNY training academy

Six are sons of firefighters or police who died of 9/11-related illnesses.

"They are honoring their fallen loved ones," Fire Commissioner Dan Nigro said. "They are continuing their family’s legacy of service and they are making all of us immensely proud."

There had never been a probationary class filled with as many children of 9/11 victims, Nigro said.

"These legacies are no longer children dreaming of the careers their fathers loved and of serving in the world’s greatest fire department," Nigro said. "Today, they fully achieved their dreams."
