Who owns these pyramid-shaped UFOs that are flying in restricted airspace?

Over the years, reports of pyramid-shaped UFOs have surfaced online. 


For example on December 18, 2009, a large triangle-shaped craft hovered above Red Square in Moscow and on December 18, 2018 a pyramid-shaped UFO was spotted over the Pentagon. That same year a leaked footage surfaced online of a meeting at the UN where the pyramid-shaped UFO was also discussed. 

During the meeting Maria Garces said that on December at 4.07 pm an extraterrestrial contact occurred. A metal object, shaped like a pyramid appeared over the Pentagon, Washington DC, USA. The unidentified object with a diameter around 100 meters rotated around its own axis at an altitude of around 500 meters. 

NASA operational task group, specializing in the receiving and processing of space data; received incoming data from the object. The data (information from the radars, the visual information and the fixation of the radio signals incoming from the UFO).  After analyzing all data of the object that hovered over the Pentagon, NASA explained that the object can be identified as an craft of unknown origin, hypothetically of extraterrestrial origin. 

The question is, who are they, where are they from, and what is their intention? Moreover, while the US shoots down an alleged Chinese spy balloon with a stinger missile (if you have to believe the hyped stories of the mainstream media about the Chinese spy balloon) then why are these unknown craft equipped with advanced and sophisticated technology allowed to fly with impunity within restricted airspace.
