Search for MH370 yields little

Australian authorities released their first update on the latest underwater search for missing Malaysia Airlines flight MH370 on Wednesday, saying more than 670 square km had been searched without success.

The jet, which was carrying 239 people, vanished en route from Kuala Lumpur to Beijing on March 8, and no sign of the jet has been found despite a massive air and sea search.

Flight MH370, which is believed to have crashed into the southern Indian Ocean after inexplicably veering off course, is now the subject of a renewed underwater hunt far off Western Australia state.
