When flying too far over the northwestern island, lightning will hit your plane, destroying it. Stunt Jump out of it or you might die from hitting the wings or other parts of the plane. While slowly going down you will find the crashed airliner Oceanic 815 and the word "search" written on the beach (at coordinates X1275, Y3663). Run into the jungle to find the hatch (at coordinates X1769, Y4351), as well as hear the sounds of the "black smoke" monster.
