“Taking care of our fallen airmen’s families and loved ones is our top priority,” said Puerto Rico National Guard Brig. Gen. Isabelo Rivera, according to CNN.

The plane was traveling from Puerto Rico from the 156th Airlift Wing when it crashed; the cause of the crash remains unclear.  Georgia Air National Guard Captain Jeffrey Bezore said the plane was being used for a training mission when it went down, according to CBS News. The aircraft was headed toward David Monthan Air Force Base in Arizona, WTOC-TV reported.

Images from the scene showed the wrecked aircraft on fire beneath an immense plume of black smoke.

“It was horrible,” Denver Goodwin, who works down the street from where the plane crash, told CNN. “The ground shook like a bomb was going off. All the people in the building started panicking. It was absolutely horrible.”

Prior to the doomed flight, the plane had been in Savannah for about a month undergoing maintenance, The New York Times reported. The plane was at least 50 years old, an official told CNN.
