Has any military attempted to shoot one down?
Why not?
Military have.
Iranian pilot interviewed. Usually the weapon systems or disabled or - in his case - the entire plane went ‘offline’ until the UFO was out of the area.
The UAPs can make right turns and accelerate to 20,000 mph within a second. Not really going to shoot one of those down.
They’ve also disabled nuclear systems - put them ‘offline’ when in the area.
