HUGE MISTAKE - Aircraft flying at cruising altitude generates fear and dread in residents of Rio de Janeiro, Brazil

Aircraft flying above 33,000 feet across the sky of Rio de Janeiro

RIO - The fall of a meteor in Russia on Friday left the Brazilians, especially the Cariocas (residents of the City of Rio de Janeiro), with an eye to the sky. In recent days, there were several reported sightings of similar events. At the end of Sunday afternoon, several people scattered around the metropolitan area of ​​Rio photographed and filmed what they believed to be the trail of a bright meteor. Since yesterday was the turn of the residents of the Lakes Region to witness what has been described by some as "a fireball" in the sky. According to experts, in the first case the duration of the phenomenon completely rule out the possibility that it was indeed a meteor.

To make matters worse the big mistake, nothing more, nothing less than an astronomer at the National Observatory, which by the way, do not know much about a phenomenon called "Contrail" which is vapor cloud created by the exhaust of the engines of an airplane flying loudly. The residues from the burning of fossil fuel are carbon dioxide and water vapor. At high altitudes, hot steam that is released in a very cold environment and, therefore, increases the relative humidity that exceeds the saturation point. The steam then condenses into small particles of water that freezes at low temperatures. These thousands of tiny water droplets frozen form a contrail.

Moreover, the time of day, the bright reddish color and must have been produced by the reflection of the sun, which was already very low on the horizon.

Encouraged by the press, Many thought it was a meteor as it fell in Russia

The most striking is the complete lack of care and good sense of news websites, considered important in the country, who published the news without even consulting experts or federal departments and security control of Brazilian air space. Sometimes these attitudes suggest that the media or someone with more wins all the fear generated by these events largely unknown to the population that despite all the social networking, still do not understand much of which reaches they like information.
