Looks like a bug to me.
I think they need an outdoor fogger.

One such case has just come to light in Chile, and was presented by government officials for the first time at a press conference on March 13. It was a glorious, sunny morning on Nov. 5, 2010, when crowds gathered to celebrate the changing of the Air Force Command at El Bosque Air Base in Santiago. From different locations, spectators aimed video cameras and cell phones at groups of acrobatic and fighter jets performing an air show overhead. Nobody saw anything amiss.
But afterward, an engineer from the adjacent Pillán aircraft factory noticed something bizarre while viewing his footage in slow motion. He turned it over to the government's well known Committee for the Study of Anomalous Aerial Phenomena, or CEFAA, for analysis.
The stunning conclusion: The Chilean jets were being stalked by a UFO.
In the clips below, the UFO is difficult to see because it's moving so fast. The clip is repeated with the UFO highlighted as it makes passes around three separate groups of airplanes

CEFAA officials collected seven videos of the El Bosque UFO taken from different vantage points. Bermúdez commissioned scientists from many disciplines, aeronautical experts, and air force and army photogrametric technicians to subject the videos to intense scrutiny. They all came to the same conclusions.
