According to the AARO report, a majority of documented UFOs are described as spherical, glowing white orbs ranging in size from 3 to 13 feet in diameter.
Their surfaces often appear translucent or metallic.
These orb-shaped craft can remain stationary in midair or travel at extreme velocities up to 7,000 mph - twice the speed of sound.
Notably, the objects produce no visible exhaust or discernible propulsion system, suggesting they employ advanced, unconventional forms of propulsion.
Uncle Sam narrowed it down, so what are they?
