(CNN) - President Barack Obama made his first public comments Wednesday about the search for missing Malaysia Airlines flight 370.
"We have put every resource that we have available at the disposal of the search process. Obama said, "Our thoughts and prayers are with the families, but I want them to be assured that we consider this a top priority."
It's day 13 of the search for the missing plane and still more questions than answers.
Investigators are in a race against time.
They have just 17 days to find the plane's black box before it stops transmitting that crucial signal that could help them locate the wreckage.
What do we know?
Malaysian officials announced today that some data on the flight simulator owned by Malaysia Airlines Flight 370 Capt. Zaharie Ahmad Shah had been deleted before February 3rd.
But it's unclear who deleted the information and why.
The FBI is now examining the simulator's hard-drive as well as computer hard drives belonging to both the pilot and co-pilot.
