According to the UK and Ireland edition of Yahoo! News, experts at the Committee for the Studies of Anomalous Aerial Phenomena (CEFAA) have ruled, "It is not any weather phenomenon or any other known object made by man."
That's a bold statement to attribute to scientists of a country -- any country -- especially if it's true. The problem is, that's not what the organization said.
"We usually pay no attention to press articles of this nature," said Jose Lay, international affairs director for CEFAA, Chile's official government organization that studies UFOs. CEFAA is part of the ministerial department of civil aeronautics (DGAC) -- equivalent to the Federal Aviation Administration in the United States -- which is under the authority of the Chilean air force.
"This policy has earned us, in this country, the respect of the public at large who no longer go to pseudo-ufologists to make their reports or to sensationalist press as the one that published the article in question," Lay told The Huffington Post in an email from Chile.
Other media sources that carried the same story about the UFO not being made by man included Fox News Latino.
Here's what actually happened.
After the sighting, the pictures were eventually sent to CEFAA for examination. In 2014, Lay told HuffPost blogger and best-selling author Leslie Kean that the UFO could not have been a drone operating in the mine area.
"Officials also ruled out any experimental aircraft, planes, weather balloons or anything else that could explain the incident," Kean wrote.
CEFAA investigated the photos and released its results in 2014, suggesting that the object, photographed from two different positions in the sky (see second image below), left witnesses with the impression that it was under intelligent control.
