On the night of last July 30 a green bright craft the size of a commercial jet flew for approximately two hours over three countries in South America, Argentina, Uruguay and Brazil, covering a distance of approximately 3400 km (2125 miles). It was witnessed by hundreds of people. Dozens of videos were posted on YouTube. Media tried to suppress the real measure of the event, giving false explanations to the phenomenon and in a hastily manner. Authorities involved are completely silent. I was at home at the time teaching English. I received an email from a friend on the next morning with a link to a news report about the case. At a first glance it really appeared to be a meteor, but it didn't take too long to notice that the press was hiding something due to the vast area where the object had been seen. It flew at variable speeds and altitudes over 3 countries in several directions. I had the feeling I should do something about it, and I did. I have prepared and stored in Dropbox a 25 page very detailed report. It contains pictures, 32 videos, several calculations, proving that it was an intelligently controlled craft. Please contact me, I suspect you will appreciate seeing my report published in your monthly journal.
