This UFO sighting took place on March 19, 2020. It was SpaceX’s fifth launch of Starlink satellites, and it won’t be the company’s sixth since it failed to land on the company’s drone ship in the Atlantic as planned. As the rocket’s first stage returns to Earth, a flying object unidentified passes it.
The item is likely to be a fairing, or any other component of the rocket because it is moving at a rapid speed up while the first stages are returning.
The UFO comes dangerously close to colliding with SpaceX’s Falcon 9 rocket! You can take a look at the video to make your own decision.
