The English idiomatic phrase X originates from a World War II song, with lyrics by Harold Adamson and music by Jimmy McHugh, published in 1943. The song describes the aftermath of an Allied night bombing mission.

Despite the danger, the crew remains optimistic as the aircraft struggles home, capturing the spirit of X. What X?
