No debris found yet to aid MH370 search WEST Australian coast dwellers have been diligently reporting discoveries of potential debris from the Malaysia Airlines plane wreck lost in the Indian Ocean. BUT so far none have been connected to the missing MH370. The plane disappeared with 239 people on board during a March 8 flight from Kuala Lumpur to Beijing and its whereabouts remains a mystery. Ocean experts at the CSIRO are undertaking modelling to identify areas where debris could potentially wash ashore if it crashed into the Indian Ocean search zone. Initially they expected some on the west coast of Sumatra within 120 days of the crash, but nothing has been found. Search co-ordinator Peter Foley said people in WA and other Indian Ocean rim countries were regularly handing in flotsam and jetsam to police. Photographs are forwarded to experts at the Joint Agency Coordination Centre, Boeing and Malaysian investigators. "Every week we've had someone reporting something," he told reporters in Canberra on Wednesday. Authorities have combed 7000 square kilometres metres of the 160,000 kilometre search zone to date. The high tech underwater sonar search was progressing well and weather conditions were favourable. The Fugro Equator vessel is conducting mapping while Fugro Discovery is resupplying at Fremantle. The two ships are towing sonar equipment that feed data back in real time, covering about 120 square kilometres per day. A third ship, Go Phoenix, will soon return to resupply at Fremantle. It covers about 140 square kilometres a day. Each ship has 35 personnel who work 12 hour shifts monitoring the search. They stay out at sea for 42 days at a time. It takes the ships 5.5 days to return from the search zone to Fremantle. Experts involved in the Air France Flight 447, 2009 plane wreck recovery off the coast of Brazil had provided valuable lessons to the JAAC. For example leaving some unnecessary equipment behind so the search ships are not weighed down too much and can cover more ground. Authorities believe the search could take up to a year.
