Police isolated and surrounded the Saudia flight after it landed just after one of its pilots released a distress signal indicating a hijack incident. A pilot of a Saudi Arabian Airlines flight accidentally pressed a hijack alarm, triggering a major security response at Manila airport on Tuesday, authorities said. The aviation authority statement said the distress signal pressed by the pilot alerted authorities "that a hijacking incident is on progress on board". "Apparently the pilot committed an error activating the 7500 squawking signal," the statement said, referring to the hijack alarm. It said an investigation would still be needed to confirm why the distress signal was pressed.
