The search for missing Malaysia Airlines flight MH370 is now into its second week. On Saturday Malaysian Prime Minister Najib Razak said, "We are still investigating all possibilities as to what caused MH370 to deviate from its original flight path."

Razak also said that the plane was steered off course by someone on board. ABC News reports Razak also said the flight was airborne for more than seven hours and it may have traveled as far as Kazakhstan.

During the Saturday press conference Razak presented a different timeline than what was previously disclosed. The last confirmed communication between the plane and a satellite was at 8:11 a.m. Malaysian time, a week ago. The search has now expanded to the north to Kazakhstan and to the south to the South Indian Ocean. The search area stretches more than 5,000 miles.

The missing MH370 was carrying 239 people when it disappeared above the waters between Malaysia and Vietnam.
