Two Potential Clues To Location Of Plane

There are two potential clues to the disappearance of an AirAsia plane off of Indonesia -- but they are hundreds of miles apart.  

Searchers have spotted oil patches in the Java Sea, near where the plane lost contact yesterday. Samples are being collected and analyzed.  

The crew of an Australian aircraft has also spotted what are called ``suspicious'' objects in the water about 700 miles from where the plane disappeared. Officials say they don't yet know if there's any connection to the missing plane, which carried 162 people.  

The search will be expanding onto land areas in Indonesia after daybreak there -- but the search and rescue chief says it's believed that the plane is ``at the bottom of the sea.''  

It disappeared from radar yesterday -- shortly after the crew had asked for permission to increase altitude because of rough weather. The request wasn't immediately granted because of heavy traffic.  

The plane was last seen on radar four minutes after the final communication from the cockpit.  

At least 15 ships and nearly a dozen aircraft are involved in the search.
