EgyptAir Investigators May Have Caught a Break

A possible big break in the hunt for the wreckage of EgyptAir Flight 804: Investigators say they've detected a signal from an emergency beacon on the plane, reports the BBC. The discovery will narrow the scope of the search to an area with a 3-mile radius in the Mediterranean, says the chief Egyptian investigator. The signal came not from the black boxes but from a separate transmitter on the plane, reports the AP.

Still, the signal's detection should be a big help to a French vessel that on Friday reached the area with equipment designed to zero in on the black boxes. While debris and human remains have been recovered, authorities have no hard evidence yet to determine what brought down the jet with 66 people last week. (More EgyptAir crash stories.)
