Rio de Janiero, Brazil ? Emergency workers on Saturday recovered the flight-data recorder and the bodies of 19 people who died when their plane exploded on impact in a crash in a mountainous region outside Rio de Janeiro.

Remains of the victims were brought to the city’s morgue for identification. Only four people had been identified by Saturday night, said Roger Ancillotti, the morgue director.

“Most bodies are beyond recognition,” he said.

The LET 410 double-propeller plane owned by the local airline TEAM, which was carrying 17 passengers and two crew members, crashed Friday night in a remote area near Saquarema, some 60 miles east of Rio. The cause of the crash was not immediately known.

Authorities said that there could have been light rain and fog when the Czech-made plane crashed.
