Search For Missing Jet Focuses On Objects Seen Off Australia

Developing: Satellite images of what might be debris from the jet are the first "credible lead" in the hunt for Malaysia Airlines Flight 370, an official says. Follow the news as it comes in.

Satellite images showing objects floating in the Indian Ocean have focused the search for Malaysian Airlines flight 370 and the 239 people who were on board to an area about 1,500 miles southwest of Perth, Australia.

This is, in the words of acting Malaysian transport minister Hishammuddin Hussien, the first "credible lead" since the plane disappeared on March 8 while on what was supposed to be a flight from Kuala Lumpur to Beijing.

As NPR's Frank Langfitt reports, one of the objects is thought to be about 80 feet long. He adds this cautionary note: Officials say debris is not uncommon in that part of the Indian Ocean. Objects often seen floating there include containers that have fallen off ships.

We'll be updating as the story develops. The Sydney Morning Herald is among other news outlets that are also live blogging. Bear in mind: Perth is 12 hours ahead of the East Coast of the U.S.

6:30 a.m. ET. First Flight Crew Unable To See Anything:

"RAAF P3 crew unable to locate debris. Cloud & rain limited visbility. Further aircraft to continue search for #MH370," the Australian Maritime Safety Authority tweets.

RAAF is an acronym for the Royal Australian Air Force. P3 refers to the P-3 Orion maritime patrol aircraft built by Lockheed Martin.
