" A reporter with the Chinese state broadcaster, CCTV, who is on board Haixun, said the ship had first picked up the signal on Friday, when pings were detected intermittently for about 15 minutes. But other vessels were in the vicinity, raising the possibility that they might have been the source.
Haixun then heard the signal again on Saturday, when the pings were picked up every second for 90 seconds.
Objects floating in the sea, which may have been wreckage, were also photographed by a Chinese reconnaissance aircraft about 60 miles from where Haixun detected the pings.
Haixun is a patrol and survey ship operated by the China Coast Guard. Weighing 5,400 tonnes and with a length of 430ft, the vessel is capable of conducting search, rescue and survey missions thousands of miles from its home base. "
