S1·E4 Souls On Board

Just as the Others board a plane to Sedona, Arizona for a psychic conference, they learn that an inquisitive Miles purposely booked them on the same flight path previously occupied by an aircraft that recently crashed, and the harrowing activities they witness are thought to be somehow linked to parts salvaged from the wreckage -- and recycled onto their jetliner. As the Others react to the sight of tormented faces pressed against the outside windows and through the cabin walls, Marian has a strange encounter with the captain of the doomed crew, who has an urgent message only Miles can decipher.
