Investigators looking into the June 1 crash of Air France Flight 447 already have a "remarkable amount of information," even though the plane's voice and data recorders have yet to be found. A U.S. military official said two ships were halting their search for the black boxes on Friday, though submarine searches are likely to continue. Meanwhile, investigators continue to pore over physical evidence and computer data from the crash. Kevin Darcy, a former accident investigation chief at Boeing Co. says the long, plodding investigation is good for the aviation industry. "There's almost always a wealth of information that comes out from a thorough investigation that not only helps you figure out how to prevent that accident, but other accidents as well that share the same links," he says.
