Songbird
performed by Eva Cassidy

The film begins with a voiceover from David, commenting that, whenever he gets gloomy with the state of the world, he thinks about the arrivals terminal at Heathrow Airport, and the pure, uncomplicated love felt as friends and families welcome their arriving loved ones. David's voiceover also relates that all the known messages left by the people who died on the 9/11 planes were messages of love and not hate. The film then tells the "love" story of many people, culminating in a final scene at the airport enacted to the tune of The Beach Boys' "God Only Knows", that closes their stories. The film ends with a montage of anonymous persons greeting their arriving loved ones that slowly enlarges and fills the screen, eventually forming the shape of a heart.
