Identified airborne objects have been recognized by a government agency called the CDC. In early May 2021 the CDC finally recognized that COVID-19 is airborne instead of strictly droplet based.
The droplet based theory meant that 6 feet of physical distancing would prevent the virus from spreading between people. However studies have shown that the virus can linger in the air for up to three hours in tiny particles and spread much further than 6 feet. The risk of transmission is greatest within three to six feet of an infectious source where the concentration of these very fine droplets and particles is greatest.
Once infectious droplets and particles are exhaled, they move outward from the source. The risk for infection decreases with increasing distance from the source and increasing time after exhalation. Two principal processes determine the amount of virus to which a person is exposed in the air or by touching a surface contaminated by virus.
An MIT research paper concluded that the risk of being exposed to Covid-19 indoors can be as great at 60 feet as it is at 6 feet in a room where the air is mixed. Existing safety guidelines have omitted too many factors to accurately quantify the risk of airborne transmission, such as time of indoor exposure, mask use and ventilation rates. The danger of exposure now is mostly for those who have not been vaccinated.
On April 27, 2020 Pentagon officially unclassified three videos taken by US Navy pilots showing “unidentified aerial phenomena,” known as UFOs. It seems very mysterious that they would release these videos shortly after the start of the pandemic. When the $2.3 trillion coronavirus relief and government funding bill was signed into law in December, 2020, a 180-day countdown began for US intelligence agencies to tell Congress what they know about UFOs. In June 2021 the Office of the Director of National Intelligence and other agencies are scheduled to deliver unclassified reports on UFOs to Congress.
