In February 2020, an Airbus A320 was on a routine flight soaring over Medellin, Colombia. Little did the captain know that he was about to discover that he was sharing the friendly skies with an unidentified flying object.
The pilot kindly shows us his altimeter, indicating that he is flying at an altitude of approximately 30,000 feet. He then points his camera phone out of the cockpit window, and as he zooms in, a metallic-looking object, which appears to be a polyhedron of some sort, whizzes by in a straight line.
We slowed down the footage and zoomed in further, revealing a cube-like object with protruding points. The object appears to be darker in color and does not resemble a bright, shining balloon.
Whatever it is, it certainly shouldn't be there. One theory is that if we were visited by another civilization, they might send probes ahead of their actual arrival.
