An Unidentified Flying Object (UFO) spotted by thousands of protesters in Sao Paulo on the evening of 17 June has been identified as a drone controlled by a TV station.
A video of the glowing light hovering over the skies was recorded and posted on YouTube by one of the protestors. The video soon started circulating on the internet and led many to believe it was a sign of alien life.
However, the UFO's mystery was solved following another video uploaded on YouTube displaying the footage recorded from the flying object.
The drone, with a camera attached, was apparently controlled by local news station Folha TV.
According to a report in The Huffington Post, experts believe that in future with cheaper drone technology, there certainly will be a surge in the number of UFO sightings - which could spread panic among the general public.
"The whole business of UFOs is sold under the faulty logic of ignorance. We don't know what it was, therefore we know what it was," Joe Nickell, an investigator with Skeptical Inquirer, told the publication. "If you put anything up in the sky it will end up a UFO to many people.
"We don't call in planes or weather balloons as UFOs anymore, but drones are small, peculiar aircraft. They're unfamiliar."
Marc D'Antonio who has constructed a flying saucer in collabration with National Geographic to demonstrate how easily people can be duped into an alien hoax, added: [My project] showed I could walk into any hobby shop and in just 24 to 48 hours produce a craft.
"Already, five percent are probably drone-related. Drones themselves are going to be taking centre stage for a great deal of time."
In a similar incident in 2011, a mass UFO sighting was reported by a crowd of 25,000 people who were protesting in Moscow. Later it was discovered that the UFO was a drone controlled by a local TV station.
