A television camera filming a football match captured the moment a strange white object flew overhead.
The incident took place at el Nuevo Gasometro in Argentina during a match between San Lorenzo and Botafogo.
The footage shows the crowd cheering and chanting at what's happening on the pitch just as the peculiar object emerges from above the stands on the left. It moves across the picture at considerable speed and then disappears off the right side of the frame towards the stands on the opposite side.
There are no flashing lights or other indicators that the object is a conventional aircraft and it seems to move too quickly to be a blimp or balloon. The object also appears to change direction slightly just before disappearing out of view.
