BEIJING (Reuters):China said on Wednesday (April 20) the black boxes of a Boeing 737-800 jet that crashed last month were badly damaged, leaving virtually no publicly available clues to explain its violent plunge into a wooded hillside, killing all 132 people on board.

China Eastern flight MU5735 from Kunming to Guangzhou plunged from cruising altitude into the mountains of Guangxi on March 21 in China's first fatal air crash since 2010.
