The tragic crash of Germanwings Flight 9525 has left the world in mourning. The 150 victims hailed from 18 different countries, including the United States. Right now, the families of the deceased and those investigating the accident are urgently trying to figure out what went wrong. One portion of the crucial black boxes, the cockpit voice recorder, though badly damaged, has been recovered and apparently reveals that the co-pilot was responsible for intentionally crashing the aircraft. Due to the rugged and inaccessible terrain of the crash site and the high speed of impact, investigators are having a difficult time finding the flight data recorder.
