CNN has learned more about the actions of the pilot and co-pilot of Malaysia Airlines Flight 370 leading up to moments the plane vanished two weeks ago.
U.S. investigators say they found evidence that files were deleted from the pilot's simulator after February 3rd.
Malaysian authorities had originally said the items were deleted before that date.
Britain's The Telegraph newspaper reported Friday it had obtained a transcript of the final communications between the Malaysia Airlines flight cockpit and air traffic controllers.
The report showed what's being described as routine conversations about what runway to use and at what altitude to fly.
Included in the search is a high-tech U.S. Navy surveillance aircraft called the P-8 Poseidon.
The military is not allowing camera crews on that plane.
But our David Mattingly got exclusive access to that exact same plane.
