The missing Malaysia Airlines jetliner probe is now focused on anyone connected to Flight 370, including ground crew at the airport. 

Malaysia's acting transport minister says a key focus is on the flight crew. 

Authorities found a flight simulator at the home of the missing airliner's captain. 

A police official said the simulator's programs seemed to be normal ones used to practice flying and landing in various conditions. 

Meanwhile, postings on the captain's Facebook page indicate he was a politically active opponent of the Malaysia's ruling coalition.
