Malaysia Airlines Flight 370

Malaysian, American and other authorities investigating what happened to a missing jetliner en route to China one week ago are concluding that its disappearance was a deliberate action. Malaysia’s prime minister confirms that whatever took Flight 370 off course was not an accident.

The search for a Malaysia Airlines passenger jet, which vanished last Saturday, has expanded — with more seemingly conflicting information emerging about its last known position. Vessels from various coast guard agencies and navies, including the United States, are expanding the search across a vast swath of southern Asia for any trace of Malaysia Airlines Flight 370.
