A Chinese patrol vessel searching for the remains of missing Malaysia Airlines flight 370 has detected a signal in the Indian Ocean, according to Chinese media.<br /><br />The state-run news agency Xinhua said that ultrasonic pings have been captured at the same frequency as the flight recorders on board the plane. <br /><br />But they’ve stressed that this does not confirm that flight 370 has been found. <br /><br />The boat forms part of a nine-strong search and rescue operation to the west of Perth off the coast of Australia. <br /><br />“Haixun 13” carries specialised rescue personnel and is equipped with three facilities, one of whose job it is to search for the aircraft’s “black box” of flight data. <br /><br />The batteries on black boxes last around thirty days. As that deadline approaches, the race is on to find the plane in the remaining narrow window of time.<br /><br />Relatives of the missing remain frustrated after being told by Malaysian officials that the aircraft had gone down with no survivors, despite an apparent lack of evidence to support this.
