UFOs were reported flying near the McGuire Air Force Base and nearby Fort Dix Base in Trenton, New Jersey, before state Police requested entry to investigate.
But the events which allegedly then unfolded go way beyond the traditional UFO sighting.
It is claimed a military police officer based at Fort Dix reported seeing "a low-flying object pass over his car" as he drove.
After braking, he claimed to see in front of his car "a small being with a large head, black eyes, and a very slender body".
He claims he panicked, got out of the car and pulled out a .45 automatic gun, before demanding the being lay on the floor.
But, after his request was ignored, he fired a number of shots.
The wounded creature is alleged to have jumped a fence into the McGuire base before heading down a runway.
But, according to the case, it then collapsed dead.
