Wikipedia
Contrails (; short for "condensation trails") or vapor trails are line-shaped clouds sometimes produced by aircraft engine exhaust, typically at aircraft cruise altitudes several miles above the Earth's surface. Contrails are composed primarily of water, in the form of ice crystals. The combination of water vapor in aircraft engine exhaust and the low ambient temperatures that often exists at these high altitudes allows the formation of the trails. Impurities in the jet exhaust from the fuel, including sulfur compounds (0.05% by weight in jet fuel) provide some of the particles that can serve as sites for water droplet growth in the exhaust and, if water droplets form, they might freeze to form ice particles that compose a contrail. Their formation can also be triggered by changes in air pressure in wingtip vortices or in the air over the entire wing surface.
Depending on the temperature and humidity at the altitude the contrails form, they may be visible for only a few seconds or minutes, or may persist for hours and spread to be several miles wide, eventually resembling natural cirrus or altocumulus clouds. Persistent contrails are of particular interest to scientists because they increase the cloudiness of the atmosphere. The resulting cloud forms may resemble cirrus, cirrocumulus, or cirrostratus, and are sometimes called cirrus aviaticus. Persistent spreading contrails are thought by some, without overwhelming scientific proof, to have a significant effect on global climate. Persistent contrails are sometimes called chemtrails in reference to the conspiracy theory regarding the undisclosed spraying of chemical or biological agents by various high-flying aircraft.

"Contrail" is a song recorded by Japanese recording artist Namie Amuro for her eleventh studio and second bilingual ( Japanese and English language) album, Feel (2013). The track was entirely written, composed, arranged, and produced by Japanese musician Nao'ymt. The single premiered on May 29, 2013 as the lead single from the album, and her second digital-only single. Musically, "Contrail" is a dance song, influenced by electronic dance music. Lyrically, it is a self-empowerment anthem that discusses themes of confidence and hope.
Upon its release, the track garnered generally favorable reviews from music critics. Many critics highlighted as one of the album's best tracks, and complimented Nao'ymt's songwriting and production. Although it was unable to chart on Japan's Oricon Singles Chart because of their restriction of digital sales, it did achieve success on the Japan Hot 100 chart provided by Billboard, peaking at number eight. It was certified platinum by the Recording Industry Association of Japan (RIAJ) for digital sales of 250,000 units. An accompanying music video was shot in downtown Los Angeles, California at Pershing square, which featured Amuro walking through the city with children. Amuro has performed the song on her Feel Tour (2013), and her 2014 Live Style Tour.
