Jerry Panowski works at an airport, and his friend Chuck Lambert was piloting Flight 2485 when the plane crashed. Dean and John Winchester helped Jerry with a poltergeist in the past, so he calls Dean and Sam to investigate.
Jerry had encountered a poltergeist problem a few years earlier in Pennsylvania and had already been helped out once by John and Dean. So when he listened to the voice recorder from the crashed Flight 2485, he knew instantly that it was worth calling again. He phoned John's cellphone number, but received a recorded message telling him to call Dean.
