[Tense Sound Design Driving Sadness] Haunting, foreboding cut that uses snippets of airplanes' black box recordings of ill-fated flights, heartbeat-like loops of airplane ambience, machine gun cockings, samples of news music, orchestral strings and, @:29, a simple prepared piano figure that repeats throughout. Distorted, filtered drum breaks start @1:07 and trade back and forth with the theme. @1:45 the full mix begins with a more driving, questioning mood that makes the cut great for investigations and mysteries.
