Search for missing Malaysia flight to resume in August

Australian investigators are about to announce the next phase in the search for Malaysia Airlines Flight 370.

More than three months after it vanished, there is still no trace of the jet, CBS News transportation correspondent Jeff Pegues reports. For weeks, a team of international experts has been analyzing satellite data from the missing plane, trying to pinpoint once and for all where it may be.

The search zone will shift but investigators remain convinced the missing jet will be found along the 7th arc in the southern Indian Ocean where the plane last communicated with a satellite.

The search is expected to resume in August.

It was suspended in late May after failing to find any signs of the missing plane and the 239 people on board.

But British satellite company Inmarsat claims the initial phase of the search did not reach the region where the plane likely crashed.

The search location was rerouted when investigators discovered a series of pings they believed came from the plane's black boxes. After seven weeks of scouring the ocean floor, investigators announced those pings were most likely unrelated to Flight 370.

An Inmarsat company spokesperson said so-called "handshakes," or contact between the plane and the satellite, indicate, "the refined search area will be large and encompass the region of highest probability."

Without the plane's black boxes, questions also remain about why the jet veered off course.

On Sunday, Malaysian authorities denied a British newspaper report claiming that new leads in the investigation are focusing on the pilot and his flight simulator.

The report claims, "The official Malaysian police ... has identified the captain as the prime suspect after checks cleared all the other people on board."

The Malaysian police called the report "irresponsible" and "baseless."

There are currently two vessels mapping the sea floor, a process that is expected to take three months to complete. That work is underway in a 23,000 square mile area, almost the size of West Virginia.
