A local villager living near the crash site of the China Eastern Airlines plane recalls the moments after the fatal incident. At least 1 piece of the Boeing 737-800 appears to have broken loose well before impact. "There is no use to be afraid. I didn't know what it was, just heard an explosion and then guessed it was a plane crash," said Shi, who only gave his last name. Local villagers were also being enlisted to help deliver food and supplies, according to state broadcaster CCTV. The piece suspected to have come from the China Eastern Airlines jet was found about 10 kilometers (6 miles) from the main wreckage area, Chinese officials said at a briefing Thursday. If investigators confirm that the part came from the jet, it would indicate the plane suffered some kind of midair breakup, which could offer clues about what led to Monday’s crash or at least shed light on the flight’s final seconds. “The questions are: exactly what piece was it and when did it come off?” said Jeff Guzzetti, the former chief of accident investigations at the U.S. Federal Aviation Administration. Flight MU5735 from Kunming to Guangzhou went down without an emergency radio call from pilots, slamming into a forested hillside about 100 miles from its destination, according to the Civil Aviation Administration of China. There were 132 people aboard. The highly unusual dive has baffled crash investigators and safety experts. Aircraft such as the 737-800 are designed not to dive so aggressively, so some kind of aircraft failure or pilot action would be required to keep its nose pointed down for so long. A piece about 1.3 meters (4.3 feet) long and 10 centimeters (4 inches) wide believed to be from the plane was found on farmland, Zheng Xi, head of the Guangxi fire-fighting rescue team, said at a briefing. It’s impossible to know at this early stage in the investigation whether the piece came loose as a result of stresses during the high-speed plunge or broke off before the sudden descent. Guzzetti said it most likely occurred as the plane plummeted from a cruising altitude of about 29,000 feet in about 1 minute and 35 seconds. “In my view, that’s the aircraft shedding parts as it’s coming down,” he said. If that’s the case, it would provide clues about the plane’s speed and possible pilot maneuvers.
