Interesting footage posted to YouTube
When the Calbuco volcano erupted last week, several observers caught what looked like a UFO hovering near the ash plume. The object appeared to be two glowing spheres, and it reportedly hovered in mid-air for several minutes before vanishing.
Several experts analyzed the footage and determined that it was legit, and not either a hoax or a CGI effect. But that left the question, what was it?
Enter Marc Dantonio, an FX expert and the chief photo and video analyst for the Mutual UFO Network (MUFON). Dantonio looked at the footage from several angles, and determined that it was most likely a drone.
According to Dantonio, the various angles show that the drone was smallish and close to the camera. It's difficult to tell scale from video like this, which is why it's understandable that some people thought the object was large and far-away.
Most likely the drone belonged to someone in the nearby town who decided to use it to get a better view of the ash plume. Understandable, certainly.
