5th Signal Might Not Be From The Missing Plane

The search is still on for the missing Malaysian airplane Flight 370. All hopes on finding the airplane were tempered on friday (11/4/14) when the joint search said the the latest signal probably isn't from the missing airplane.

The most recent acoustic signal detected by an
Australian aircraft in the search Thursday is
"unlikely to be related to the aircraft black boxes,"
Australian chief search coordinator Angus Houston
said in a statement Friday.

"On the information I have available to me, there
has been no major breakthrough in the search for
MH370," Houston said.

But Australian Prime Minister Tony Abbott told
reporters in China on Friday that authorities are
"very confident" the signals picked up by acoustic
detectors are coming from the black box of missing
Malaysia Airlines Flight 370, CNN affiliate Sky News
Australia reported.

It's unclear whether Abbott was referring to four
signals detected earlier this week.
