🇺🇸 USAF — Project Blue Book
In August 1949, several witnesses in San Francisco observed unidentified aerial objects with oval and square shapes, traveling at speeds higher than jet aircraft. These objects, described as silvery and solid, showed no signs of propulsion or landing. Some witnesses reported seeing between two and seven objects in formation, disappearing behind fog. Military authorities confirmed that radar testing devices, called "kites," were regularly launched in the area, but witness accounts did not fully align on details like shape, altitude, and direction. Despite investigations, no clear explanation was found for the sightings.
