A vapor trail , or contrail, is a condensation trail made by the exhaust of an aircraft engine.
Vapor Trail or Vapour Trail may also refer to:
In physics, a vapor or vapour is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapor can be condensed to a liquid by increasing the pressure on it without reducing the temperature of the vapor. A vapor is different from an aerosol. An aerosol is a suspension of tiny particles of liquid, solid, or both within a gas.
Contrails or vapor trails are line-shaped clouds produced by aircraft engine exhaust or changes in air pressure, typically at aircraft cruising altitudes several kilometres/miles above the Earth's surface. They 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 at high altitudes causes the trails' formation. Impurities in the engine exhaust from the fuel, including soot and sulfur compounds provide some of the particles that serve as cloud condensation nuclei for water droplet growth in the exhaust. If water droplets form, they can 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. Contrails, and other clouds caused directly by human activity, are called homogenitus.
Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation. It is less dense than most of the other constituents of air and triggers convection currents that can lead to clouds and fog.

Vapor Trails is the seventeenth studio album by Canadian rock band Rush. It was released on May 14, 2002, on Anthem Records, and was their first studio release since Test for Echo (1996), the longest gap between two Rush albums. After the Test For Echo tour finished in July 1997, drummer and lyricist Neil Peart suffered the loss of his daughter and then his wife in separate tragedies. As a result, the group entered an extended hiatus during which it was not certain they would continue. They eventually reunited in January 2001 to rehearse material for a new album, recording for which lasted until December. For the first and only time since Caress of Steel (1975), the group did not use any keyboards or synthesizers in their music, incorporating many layers of guitar, bass and drums instead.
The chemtrail conspiracy theory is the erroneous belief that long-lasting condensation trails left in the sky by high-flying aircraft are actually "chemtrails" consisting of chemical or biological agents, sprayed for nefarious purposes undisclosed to the general public. Believers in this conspiracy theory say that while normal contrails dissipate relatively quickly, contrails that linger must contain additional substances. Those who subscribe to the theory speculate that the purpose of the chemical release may be solar radiation management, weather modification, psychological manipulation, human population control, biological or chemical warfare, or testing of biological or chemical agents on a population, and that the trails are causing respiratory illnesses and other health problems.

"One Little Victory" is the opening track and first single from Rush's 2002 album Vapor Trails, with music by Geddy Lee and Alex Lifeson, and lyrics by Neil Peart. The title phrase was inspired by a line from Joni Mitchell's "Sunny Sunday." To herald the band's comeback after a five-year hiatus, the single was designed to grab the attention of listeners with its rapid guitar and drum tempos.

A vapor is a substance in the gas phase below its critical temperature.
The Stars Look Down is a 1935 British novel by A. J. Cronin.
A homogenitus, anthropogenic or artificial cloud is a cloud induced by human activity. Although most clouds covering the sky have a purely natural origin, since the beginning of the Industrial Revolution, the use of fossil fuels and water vapor and other gases emitted by nuclear, thermal and geothermal power plants yield significant alterations of the local weather conditions. These new atmospheric conditions can thus enhance cloud formation.
"Contrail" is a song by Japanese recording artist Namie Amuro, taken from her eleventh studio and second Japanese–English bilingual album Feel (2013). The singer was approached by the Tokyo Broadcasting System team to record the official theme song for their television series Flying Public Relations Office, which resulted into the process of "Contrail". The track was written, composed, arranged and produced entirely by long-time collaborator Nao'ymt, and recorded at Daimonion Studios in Shibuya, Tokyo. Musically, "Contrail" is a dance number that includes instrumentation of synthesizers, keyboards and a drum machine. A self-empowerment anthem, the title derives from the literal term, and is delivered as a metaphor for confidence and hope.
On the evening of Monday, November 8, 2010, an unusually conspicuous contrail appeared about 35 miles (56 km) west of Los Angeles, California in the vicinity of Catalina Island. News footage of the event from a KCBS helicopter led to intense media coverage and speculation about a potential military missile launch, with many reporters and experts discussing the contrail and theorizing about its source.
