COMING BACK FROM WORK ON NORTH DIRECTION ON MONUMENT BLVD. I SAW A PERFECT BOW LIKE FORMATION CONCAVE FROM MY POINT OF VIEW OF 5 PLUS OBJECTS. AT FIRST I THOUGHT THEY WERE HELICOPTERS,BUT THERE WAS NO BLINKING RED AND WHITE LIGHTS, AND NO SOUND AT ALL CONSIDERING THAT THEY WERE FLYING LOWER THAN A HELICOPTER. THE ORBS WHERE FLYING BELOW THE SPEED OF 50MPH BECAUSE I PASSED THEM SHORTLY AFTER, TOOK A RIGHT AND LEFT AT THE T INTERSECTION AND LEFT TO SEE THEM BETTER, BUT ONLY 2 REAMINED STATIONARY, AFTER BEING UNABLE TO RECORD THEM I TRAVELED SOUTH NOTICING 2 MORE ORBS AND THEN AFTER THOSE DISSAPEARED FLYING EVER SLOWLY NW, 2 MORE SHOWED UP BUT THIS TIME THEY SEEMED TO BE VANISHED IN FRONT OF ME AT APROXIMATELY A MILE AWAY. I HEARD 3 DISTINCTIVE VOICES ACROSS FROM NEIGHBOORS A WOMAN ONE OF THEM, THE NIGHT WAS QUIET AND 80% CLEAR, JUST A COUPLE OF COUPLE OF CLOUDS.AFTER I RECORDED VIDEO SAME NIGHT OF AN OPEN AREA FROM A PARK NEAR BY AS COMPARISON.ALSO RECORDED TRAJECTORY DURING THE DAY, AND SEVERAL AIRPLANES AND HELICOPTERS, AND NO MATTER HOW FAR SOUND WAS AUDIBLE
