Condensation trails coming off the trailing edge flaps can appear especially odd, since the trail is being " spun " by aerodynamic forces.

And you can see the flare, a flash of light from the rocket's rear and a misty condensation trail, reflected in the water.

The hot, humid exhaust produced by jet engines forms condensation trails, a familiar sight high in the sky, particularly near air travel corridors.

Some of the changes in Asia caused by America's war on terrorism may fade as quickly as the condensation trails of the B-52 bombers over Afghanistan.

The white lines, known as condensation trails, are produced not by jets alone; they are also visible in footage of slower World War II-era aircraft, he says.

These clouds are commonly known as condensation trails ( contrails ) and are initially lineal " cirrus clouds " that could be called " Cirrus anthropogenitus " ( Cia ).
17.
These arguments have been dismissed by the scientific community : such trails are normal water-based contrails ( condensation trails ) that are routinely left by high-flying aircraft under certain atmospheric conditions.
18.
Figures from British Airways suggest carbon dioxide emissions of 100g per passenger kilometre for large jet airliners ( a figure which does not account for the production of other pollutants or condensation trails ).
19.
In certain atmospheric conditions where the humidity of the air is high, aircraft flying at low altitudes sometimes leave a condensation trail that can come off the top of the wing, wingtips, or trailing edge flaps.

The military command responsible for the defense of North American airspace scrambled fighter jets in response to unverified reports of an airborne condensation trail, or contrail, moving from the Caribbean to the United States, defense officials said Thursday.
