I AM AN AIRCRAFT TECHNICIAN I HAVE DRIVEN THIS ROUTE TO WORK FOR YEARS. ON THIS MORNING IT WAS CLEAR NO CLOUDS AND NO BLINDING SUN. I OBSERVED AN OBJECT OF CYLINDRICAL SHAPE HOVERING OVER THE SANTA CATALINA MOUNTAINS AT ABOUT 0630 MARCH 18, 2016. I WATCHED CURIOUSLY AS MUCH AS I COULD AS I WAS DRIVING. I WITNESSED A BRIGHT LIGHT ILLUMINATE FROM ONE SIDE OF OBJECT JUST BEFORE THE OBJECT DISAPPEARED, AS IF IT JUST MELTED INTO THE SKY. I WAS DRIVING NORTHBOUND AT THIS TIME. AFTER TURNING SLIGHTLY EAST THEN BACK NORTH ONTO A DIFFERENT ROAD I LOOKED BACK TOWARD THE MOUNTAIN WHERE THE OBJECT WAS HOVERING OVER THE MOUNTAIN AGAIN. ANOTHER OBJECT IDENTICAL IN SIZE AND SHAPE APPEARED NEXT TO THE FIRST OBJECT THE DIRECTION WAS NORTH NORTHEAST. I REACHED FOR MY CELLPHONE AND OPENED MY CAMERA THE SECOND OBJECT WAS GONE AT THIS TIME. AS I ENTERED ONTO HIGHWAY I10 EASTBOUND I TRIED TO SNAP A PHOTO. IM NOT SURE IF I CAPTURED ANYTHING YET. THE OBJECT REMAINED OVER THE MOUNTAIN THE ENTIRE TIME I WAS ON I10 ESTIMATE 20MILES. I LOST SIGHT OF OBJECT BECAUSE OF MORNING RUSH TRAFFIC AND A SOUTHBOUND EXIT ONTO I19. THE OBJECT WAS GONE WHEN I LOOKED AGAIN INTHE PARKING LOT AT THE TUCSON AIRPORT. TIME 0700. I KNOW AIRPLANES AND ALL ABOUT FLIGHT CHARACTERISTICS IM 100% CONVINCED THE OBJECTS I OBSERVED THIS MORNING WERE NOT OF THIS WORLD.
