Amidst fading hopes of finding survivors, search and rescue efforts continued Wednesday to locate the last two passengers unaccounted for after Monday's Air China passenger jet crash near Pusan. The disaster countermeasures headquarters, overseeing rescue efforts, stated that some 500 firefighters, police and lower-ranking military personnel were mobilized to search for the two missing passengers. Crash investigators from South Korea, China and the United States will also visit the site for field investigation into the cause of the disaster that left 126 people dead, 38 injured and two others missing. Investigators are also expected to begin analysis of "black boxes," that will provide critical information about what went wrong with Air China Flight CA129 before its impact with a hill. The 38 survivors included Wu Xinlu, 31, the pilot of the doomed flight. In an interview with investigators Tuesday, Wu said he felt no plane malfunctions at all prior to the collision and he could not remember much else about the crash as he was thrown from the plane. So far, only three of the 126 fatal victims have been identified. Officials said they would conduct DNA test on bodies damaged beyond recognition.
