SEE the Photos of some of the passengers on missing Malaysian plane

Malaysian passenger jet with more than 200 people on board vanished in the skies over Southeast Asia.

On Monday, investigators appeared to be no closer to explaining how a large plane could disappear into thin air

 It's also been revealed that aside from 2 passengers boarding the plane using stolen passports, 5 other passengers checked on to the flight but did not board the plane. Their baggage was removed before the plane departed.

Dozens of ships and aircraft from seven countries are searching the seas around Malaysia and south of Vietnam, but so far nothing.

People are speculating that maybe the plane was hijacked, flew under the radar, to land somewhere. If this happened then it means the passengers are alive somewhere, but this theory is very unlikely.  Continue to see photos of some of the passengers on the missing plane...
