After five days of searching there still isn't any concrete answered about the disappearance of Malaysia Airlines Flight 370.
The jetliner carried 239 people.
Interpreting radar data may be key as Malaysian officials say military radar indicated flight 370 may have turned left changing course toward the Malacca strait, hundreds of miles from its last known position in the South China sea.
Authorities are also digging into the personal lives and professional records of the pilots, but insist they have an excellent service record.
"We have no reason to believe that there was anything, any actions, internally by the crew that caused the disappearance of this aircraft," said Hugh Dunleavy.
Malaysian officials told frustrated families the last words from the cockpit to air traffic control were "all right, good night" as flight 370 headed for Vietnamese air space.
