THIS WAS RECORDED IN SYDNEY AUSTRALIA ON SATURDAY 8 APRIL 24TH 2011 THERE WAS A LOUD RESONATING SOUND OUTSIDE. WE WENT OUTSIDE TO INVESTIGATE AND NOTICED A BLACK OBJECT IN THE SKY MOVING VERY VERY FAST. GOT THE CAMERA AND TOOK VIDEO IN THE DIRECTION OF THE SOUND AND THIS IS WHEN WE CAUGHT THE SHIP ON VIDEO, ONLY WHEN WE SLOWED IT DOWN REALLY SLOW DID WE ACTUALLY NOTICE THE ALIEN CRAFT. IT IS NOT A BIRD OR A PLANE, IT WAS BLACK , LOUD & MOVED ABRUPTLY EXTREMELY FAST IN ALL DIRECTIONS.
