The Indonesian search and rescue workers have recovered a black box from a Lion Air passenger jet that crashed into the Java Sea, killing all 189 people on board on October 29. The black box may provide clues on what went wrong with the flight that crashed just 13 minutes after taking off. Authorities said that the box has been sent for analysis. Reports suggest that it may take over six months to recover entire data from the black box. Search operations for bodies and debris are still underway.
