This is why I refuse to listen to these things when they're released. The thought of eavesdropping in on someone's frantic hopeless fight for survival just doesn't sit right with me.
Being from the same airline, these pilots often are at least acquainted with the crew they are hearing die. The show said that sometimes after listening it shakes the pilots up enough that they soon retire from flying.
Edit: The tape is actually owned by Jewel Palovak who this scene is also with; She's a former girlfriend of Treadwell, not his (or his girlfriends) mother.
