How many times have we looked up at the sky and seen the long white lines jet aircraft make? And how many
times have we said " Boy I wish I was on that plane?" Those long white lines are called Contrails. Contrails are made by the condensation emitted by the jet aircraft exhaust. They form when the hot, humid air
from the jets exhaust mixes with the cold air; similar to the cloud you see when you exhale and "see your breath " on cold days.
Boaters and sailors can make predictions on the weather from looking at contrails. If a jet is flying through air with low humidity, the moist air might produce a short- lived contrail. Thus, the weather will be fair. However, if
the contrail is a thick, long lasting trail it indicates that high humidity is in the atmosphere and it could be a sign of a storm brewing.
But the big storm a brewing is the effect contrails are having on our weather and climate. They are a concern to NASA and The Department of Energy. Increase jet aircraft traffic may result in an increase in cloud cover.
Cloud cover has increased by as much as 20 % in certain heavy air traffic corridors. This can have an effect on the solar energy reaching the earth's surface. This may result in surface cooling! Also the contrail clouds also
reduce energy losses of the planet, thus resulting in a warming effect of the planet! Sound familiar? Global Warming! Could jet aircraft have an impact on our weather, climate and atmospheric chemistry? NASA sent up a test
aircraft over California and it made an oval-shaped contrail. This contrail drifted across the state for 6 hours and finally turned into a 60-mile long cloud system! By the way-, it was a clear – no cloud day at the start! In the
past 30 years the number of clear days over the United States, has decreased and scientists suspect that this is the result of the increase in air traffic. So it is possible those clouds you see in the sky, were once contrails.
Jet exhaust also plays a role in changing the composition of the upper atmosphere. What happens to the pollutants and where do they go? As far as the eye can see! If the contrail expands and drifts downwards sooner
or later, it all falls down on us! People have reported that contrails clouds have fallen down on them and have made them sick. They reported that after the occurrence they have had coughs, colds, ear infections, weakness,
headaches and respiratory infections. Are jet engines using pollution controls to clean the exhaust? Is the composition of jet aircraft safe after being burned? Are people getting sick from jet aircraft? We need answer's
to these questions! Many Americans believe also that the U.S Government is conducting a secret spraying campaign over populated
areas of the country! They report that some of the contrails, when viewed with polarized glasses that the contrails have a rainbow composition when seen. This they call "Chemtrails". They also report that aircraft are making
what looks like patterns in the sky. From "X" type patterns to rows and rows - like a tractor makes plowing a field. Some say it's a chemical and biological experiment on the population of this country. And they have
formed a network of observation and reporting of these patterns! Global warming, pollution, weather experiments, chemical and biological warfare and maybe more, make those
long, puffy white lines in the sky as sinister as the mind can travel! Below are Different Web Sites for you to look into this subject of Contrails. Some are just
informational sites and some are technical. In addition, I have included some that want you to get involved in this subject! Whether it is Pro or Con – Serious or not so serious - It's up to you! Contrails | The CERES S'COOL Project | Strange Haze | Contrail Connection |
