condensation trails at ground level clouds

According to the proponents of the existence of "chemtrails" there would be quota limits under which contrails can not form and therefore any trail emitted by aircraft below this level would be abnormal and therefore " chemistry ". The facts belie this claim

. A contrail is formed if there are appropriate conditions of temperature, pressure and relative humidity (pre-existing or generated by the engine exhaust). The fee is not a parameter: simply, the above condition for the formation of contrails usually occur above a certain altitude. But nothing to prevent that occurring at low altitude or at ground level.

The photograph below is the most eloquent demonstration of this fact. It was taken November 24, 2009 at Bodaybo, Russia, and portrays a turboprop Antonov An-24RV, brands RA-46625, which takes off with a ground temperature of -43 ° C to generate contrails at ground level. The original and the details are available on Airliners.net .
