The flight crew of a Saudi Arabian Airlines plane mistakenly pressed a hijack warning button as it approached Manila's airport on Tuesday, causing airport officials to mobilize security forces and isolate the jet after it landed.
Flight SV872 from Jeddah made the distress call about 20 miles (32 kilometers) from the airport.
Airport authorities asked for a verification of the emergency message and one of the pilots confirmed the distress call verbally with the airport tower, aviation security chief Mao Aplasca said.
He said the pilot did not immediately say the emergency call was a mistake. The Boeing 777 was isolated after it landed and security personnel were deployed as a precaution. The passengers were later allowed to disembark.
