The pings at the centre of the search for missing aircraft MH370 are no longer believed to be from the Malaysian Airlines black boxes, CNN has reported.
Australian authorities narrowed the search area for the missing Boeing 777 aircraft some 1,600km off the north coast of the country after picking up a series of pings near to where the satellite data last placed the doomed plane.
CNN said authorities now almost universally believed the pings did not come from the onboard data or cockpit voice recorders, but instead from some other man-made source unrelated to the jetliner that disappeared on 8 March.
According to Michael Dean, the US navy's deputy director of ocean engineering, "Our best theory at this point is that (the pings were) likely some sound produced by the ship … or within the electronics of the Towed Pinger Locator."
