The album gets its title from a line of this song's lyrics. The song was co-written by David Gilmour and Roxy Music guitarist Phil Manzanera, who later co-produced Gilmour's On an Island album and played rhythm guitar on the subsequent tour.

It was first released as the B-side to "Learning to Fly". It was then re-released as the third single from the album in the UK where it was a minor hit and was the fourth single from the album in the US where it did well on the Billboard Mainstream Rock Tracks chart.

The track was the final song from the album played live when it was the first encore on the Momentary Lapse of Reason tour from 1987–89. The band resurrected the track on one show on their 1994 The Division Bell tour when the band performed it in Oakland, California.

The video for the track is footage of a vintage 1930s plane flying interspersed with concert clips filmed during the band's three night run at The Omni in Atlanta, Georgia. The live footage was shot in November 1987 and was directed by Lawrence Jordan (who has directed concert films for Rush, Mariah Carey and Billy Joel). Videos for "On the Turning Away" and "The Dogs of War" were also filmed from this concert.
