SYDNEY: MH370 plunged into the ocean at high speed — up to 20,000 feet a minute — reinforcing analysis that the missing Malaysia Airlines jet crashed in the current search zone, a report said on Tuesday. The Boeing 777 disappeared on March 8, 2014 en route from Kuala Lumpur to Beijing with 239 people onboard. An extensive underwater hunt in the southern Indian Ocean has not yet found the crash site, fuelling speculation it may be outside the current search zone, particularly if someone was at the controls at the end of the flight. A manned plane could have been glided down, allowing it to enter the water outside the 120,000 square kilometer (46,000 square mile) area being searched, some experts have suggested. But extensive testing by aircraft manufacturer Boeing and new Australian defense department data analysis both suggest that — regardless of the possible actions of one or both of the pilots — the jet dived into the ocean at high speed, The Australian reported.
