Where is that missing Malaysian plane? Every day that goes by brings more theories.
FOX News Radio's Simon Owen has the latest on the search:
Some reports suggest the plane was still giving off tiny bits of data after it vanished, despite dropping off radar screens and its transponder going silent.
There are suggestions it could have flown for as much as four hours, leaving its north-easterly flight path and heading west.
But authorities are cautious.
(Huessein) "The investigation team will not publicly release information until is has properly been verified."
Malaysia's Transport Minister Hishammuddin Hussein confirming the search zone is being expanded again.
