To be an airplane with jet engines? All jet airplanes leave contrails.
Any kind of powered airplane can leave contrails under the proper condition. Rocket planes always leave contrails. Jets usually leave contrails but may not if the atmospheric conditions are not right. Even internal combustion engine planes can leave contrails if they operate at very high altitude and the atmospheric conditions are just right.

The contrails are the result of 1200 degree jet exhaust being released into much, much colder ambient air.
Airplane's contrails do not form clouds; they dissipate soon after they are formed.
The white trails left behind jets are known as contrails.

No it is the weather that facilitates the production of contrails.
Contrails is a shortening of condensation trails.
First of all, its not smoke. Its Vapor! Since its so cold when you fly at 35,000FT, and the engines are so hot, you get vapor.
Jet contrails are water condensation resulting from the rapid compression and decompression of the air around the wing as the airplane moves through the atmosphere. The atmospheric conditions have to be just right for contrails to occur, and that is why you sometimes see contrails seem to wink off and on, as the airplane passes through drier air the contrails will stop.
contrails are "clouds" formed by the hot, humid air from plane/jet engines which mixes with water vapor high in the sky, then turning into ice crystals which then create contrails.
Airplanes do not release water into the atmosphere. Those cloudlike trails that you see following aircraft are called "contrails" and they are caused by the agitation of the air by the aircraft passing through it, causing water molecules suspended in the air to collide and join to create droplets.
Cirrus clouds only form at high levels, so jet plaanes fly at super high levels.
