Airline pilots see plenty of weird things while flying passengers from one place to another, but most of it occurs in the plane's cabin. However, what one pilot spotted outside of his plane has a lot of people talking. His name is Cesar and he flies Airbus A320s for Viva Air, a low-cost Colombian airline. While soaring over Medellin recently, Cesar saw a strange craft and decided to film it. He then shared the footage on TikTok.

It shows a metallic cube that seems to be moving at a high rate of speed, even though it doesn't have any noticeable wings, tail or exhaust.
