I understand that Jet Trails form when the hot exhaust from the jet turbine engines get in contact with the cold air found in altitudes of 20,000 ft. and above. It is the same principle as when the warmer air from human breath get in contatc with the ambient air on a cold winter day. I hope this helps you in any way to undersatnd the jet trail formation.
Vapour Trail
The jet contrails are exaust from the jet engines, which is mostly carbon dioxide and water vapour.
smoke
Water vapour.
Blue Light - 1966 Jet Trail 1-11 was released on: USA: 6 April 1966
The possessive form for the noun trail is trail's.Example: We seem to have arrived at the trail's end.
Jet Lag ;) get it ? Now for the actual answer. It's called a contrail, short for condensation trail.
The possessive form is jet's.
it does not form
The weatherman said that the latest jet stream would bring more cold air to the region on Friday. The jet flew over Wichita, leaving a trail of jet stream behind it.
Hit the trail: to start a journey or go for a hike. Blaze a trail: to make a new path or create a new approach. Leave a trail: to leave a visible path or evidence behind. Follow the trail: to track or pursue someone or something.
Commonly known as a contrail (condensation trail), the white vaporous trail that is visible coming out of jet aircraft is a result of three concurrent events: 1. Hot jet exhaust cooling as it exits the jet engine. 2. Atmospheric moisture (humidity. 3. Particulate matter as residue from the burning of the jet fuel. As the jet exhaust cools, water molecules condense on the minute particles of carbon in the exhaust forming water droplets and visible vapor, which appears as the white trail behind the jet. The length of the trail generally is determined by the relative amount of atmospheric moisture (humidity) present in the plane's path. The more humidity, the longer the contrail, and conversely, the less humidity, the shorter the contrail. As time passes, the contrail disperses. Wind speed at that altitude can affect how long the contrail is visible. More wind will disperse the contrail more quickly.
