It was red-eye flight the terrorists onboard could have force landed it at Sultan Ismail Petra Airport, Kota Baru, towed the plane to a big hangar under the cover of darkness, took all onboard captives except for the terrorists, confiscated all mobile phones, etc.
Do you know if there are hangars at Kota Baru that could conceal a 777?
I kinda doubt it, but if you know better, say so.
