Was Malaysia Airlines Plane Hijacked? Plane Turned Around, 2 Mystery Men On Flight Traveled Together

A Malaysian Airlines plane missing without a trace for almost 48 hours as of Sunday morning may have turned around and reversed course before vanishing from radar and losing all radio contact with air traffic control, Malaysian authorities said Sunday.

The bizarre development was just one of several elements that deepened the mystery surrounding missing Malaysia Airlines Flight 370, raising fears that the plane may have been hijacked.

A separate, unconfirmed report said that the flight also plummeted about 650 feet before disappearing.
