Still no sign of missing airplane

KUALA LUMPUR, Malaysia (AP) — Investigators say they're chasing every angle on a jet that's been missing since Saturday morning.

The Malaysia Airlines plane carrying 239 people on board was flying from Kuala Lumpur to Beijing when it disappeared over the South China Sea.

A Vietnamese official says searchers have not been able to locate a rectangular object spotted from the sky Sunday afternoon. The floating debris was thought to be one of the doors of the missing Boeing 777.

Investigators are looking into whether the disappearance has anything to do with the two passengers who were flying with stolen passports.
