There is no breakthrough in the search for flight MH370, but strong denials of dramatic media reports.<br /><br />Officials have rejected a Wall Street Journal report that the plane may have flown for four hours after losing contact with air traffic controllers. <br /><br />The paper said this was based on data automatically sent to the ground from the Boeing engines. But Malaysian officials deny that.<br /><br />Transport minister Hishammudin Hussein told a news conference: “Rolls Royce and Boeing teams are here in Kuala Lumpur and have worked with MAS *(airline) and the investigation teams since Sunday. These issues have never been raised. <br /><br />“Whenever there are new details they must be corroborated. Since today’s media reports MAS has asked Rolls Royce and Boeing specifically about the data; as far as Rolls Royce and Boeing are concerned, those reports are inaccurate.”<br /><br />Officials also say reports of debris showing up on Chinese satellite images have come to nothing.<br /><br />Amid mounting criticism, officials have also again strongly defended their search efforts, in what is being described as the most baffling mystery in modern aviation history.<br /><br />It is an agonizing wait for relatives of the 239 people on board.<br /><br />Efforts to locate the plane are being hampered by conflicting reports about its possible flight path. The searchers are now combing an area of 100,000 square kilometres.
