All 21 people aboard a military aircraft that crashed into the Pacific Ocean off the remote Juan Fernandez islands perished, Chile's government said on Saturday, as rescuers and fishermen searched for bodies. Search and rescue teams have recovered four bodies so far from Friday's crash, one of Chile's worst air disasters in recent years. "One arrives at the conclusion that the impact was so strong that it must have killed those aboard instantly," Defense Minister Andres Allamand said. The CASA 212 military plane tried twice to land on Friday before it disappeared as heavy winds and sporadic rains hit the area, according to a report of Reuters.
